Welcome to Gravity Falls!
The Reason Behind Grunkle Stan's Greed?Credit to /u/DevanteX of Reddit.
In the Gravity Falls universe, High Five Ghost is the great, great, great (However many greats) grandson of Abraham Lincoln. Only instead, he's deadIn "Irrational Treasure", Mabel finds a document that shows that underneath Abraham Lincoln's hat was a hand that stuck out of his forehead, just like our little high fiving ghost.
Candy will (or already has) create BMO, maybe even a line of them.Candy (as the strange girl), will get the idea to create an old-school gaming system, and then uses her own voice for programming.
Bill is Walt Disney's soul.
Bill's circle.This is just a theory of what the symbols on Bill's circle represent.
The author of the book was someone who associated with Stan.Stan was accompanied by someone ; possibly a friend, a lover or a relative; who wrote down all the creatures they encountered and all the rituals. There was only one book at the time, possibly heavily encrypted in a code only Stan and his associate were able to read. Later, the author 'translated' the book into standard English, dividing the content into different books and hid them away in separated places. Originally the Author intended that the books might only be used by people who knew what they were doing and who were aware of the risks they took.
Stan originally summoned Bill Cypher.He made a deal with him, resulting in him getting the Shack and all its mysteries. But after he gained all of that, Stan used his knowledge of magic and screwed Bill over. Bill went back empty handed. However he took precautions and encrypted Stan's mind, before Stan sent him back. Thus Stan has huge memory gaps.
The carpet in "Carpet Diem" belongs to (or was created/stolen by) Stancan tell by his reaction to the carpet that he knows what it is. He's not surprised by its existence or anything, and he seems pretty eager to get rid of it.
Stan's secret room behind the vending machine is actually an apocalypse bunker.I actually don't believe this one myself, but it was worth putting on here! Plus, information to back it up is found all throughout the episode "Boyz Crazy".
Gravity Falls takes place in the same universe as the Disney Animated Canon.Think about it: Almost every episode has featured at least one element that was in a Disney animated film. Living video game characters, merpeople, numbered "experiments", etc.
The warning "Stan is not what he seems" is not what it seems.It's not saying Stan is untrustworthy; quite the opposite, in fact. It's stating that Stan's borderline evil Miser act is just an act, to throw suspicion off himself. Stan is some benevolent being that's been subtly leading Dipper & Mabel in their adventures.
There will be an episode with giant vampire bats.Its obvious, in the opening while the caracters are around a campfire a face of a bat flashes by and one of the entries of the book was about vampire bats,so far most of the monsters were forshadowed like the gnomes, gideon, the time traveller ect. why not bats?
The Book was written by Dipper's future self.Being that the book had many different references to Dipper, Mabel, and everyone else.
Stan wrote the book, but then met something so horrible he blocked all memories.He still sleeps in a bunker, which he built to hide from evil creatures.
Old Man McGucket has something to with the book.He made a metal creature like the Gobblewonker look real. The journal was hidden near the metal tree that also looked real.
The Book was written by Stan's wife, who ended up getting killed in a supernatural manner.Combined with a Never Got to Say Goodbye with Stan. His terrible joke in episode 2 could've had more behind it.
There will be a crossover with Phineas and Ferb in the future.
Clyde and Betty Jo Flynn's cabin is close to Gravity Falls.Which is going to be the in-universe justification for this crossover.
In the season 1 finale, either Dipper or Mabel will either disappear or be presumed dead.And this will be a big Tear Jerker/Cliff Hanger moment.
Dipper and Mabel will gain Twin Telepathy.Twins in a supernatural town? Obvious.
This show will be the Breakout Hit of 2012, on the level of My Little Pony: Friendship Is Magic.There have already been tons of positive feedback on the show almost instantly with many calling it Disney Channel's best show since Phineas and Ferb.
Uncle Stan is some kind of supernatural creature himself.The backwards phrase during the first episode's end credits already spelled "Stan is not what he seems", and in the show's intro, look at Stan's shadow at about 0:14.
Decapitated Wax Larry King's head will be a Chekhov's Gunman.Mostly because the episode's secret code translates to HE'S STILL IN THE VENTS.
Stan is training up both Dipper and Mabel to take over the shack should (or when) something happen to him, with them unknowingly becoming his apprentices.In Tourist Trapped, he specifically chooses Dipper to go out into the woods instead of either Wendy or Soos, which is how Dipper finds the third journal. Also, as Dipper attempts to get Stan's attention to tell him about Norman, he completely ignores him and therefore forces Dipper to go out and fight on his own. In other episodes, like The Legend of the Gobblewonker and Double Dipper, he introduces Dipper and Mabel to the strange things Gravity Falls is hiding but remains an uninvolved force in the overall plot.
Gideon will be a recurring antagonist, and will either directly oppose Dipper, or keep trying to win Mabel's affection.At the end of Episode 4, it's revealed that he also has a book, presumably also full of knowledge about the mysteries and supernatural goings on about Gravity Falls. He could probably use that to his advantage in terms of getting what he wants, which is Mabel, and would probably be on the lookout for other artifacts like the amulet.
Mabel's grappling hook will make a return, either being a common or occasional tool for her and Dipper, or it will be a Chekhov's Gun.They introduced it at the end of the first episode, and it will most likely have its uses.
Stan is Obfuscating Stupidity.Stan is definitely not what he seems. He's hiding something too, and he probably knows that Dipper has the book.
Gravity Falls' nefarious undead will appear later in the series.Bonus points if Dipper initially misidentifies them as gnomes.
Waffle with big arms is real.He's one of the weirdest monsters in Gravity Falls and at some point Mabel met him.
Robbie is a Zombie.
Jeff the gnome will come back and try to get back at the twins.I mean, come on, you don't send a character flying over the horizon screaming "I'll get you for this...!" in a show with a story arc and not have him come back.
Gideon isn't human.Dipper did say "Maybe your next boyfriend will be a vampire." Now, I'm not saying he's a vampire, I have no idea what he is, but he just seems...off...
Gideon killed his parents.Well, maybe his mom since his dad, Bud Gleeful, is alive. There's no mention of her at all.
Stan is A Time Lord.That vending machine he went into in the first episode, a TARDIS. Those books, his journal of all the alien stuff he encountered on his journeys. It would also explain why Gravity Falls seems to attract the strange and supernatural.
Stan's secret bunker is a vault of the most precious thing he ever stole.This blue light was its Power Glow, and it will be MacGuffin at some point. Stan doesn't even know what it is.
Little Twelvetoes wrote the journals.Why else do you think they each have a six fingered hand on each cover?
The machine in the tree is a Reality Warper device.Once activated, it made Dipper's deepest dream come true. For all we know, Dipper's an Agent Mulder.
The characters are reincarnated/AU versions of the characters from EarthBound.Dipper=Ness. They both wear hats, Dipper attempts to use a baseball bat as a weapon in Episode 4... Gideon=Porky. Likes to call Dipper "friend", is pretty evil, doesn't seem so at first, is Dipper's enemy, might be the Big Bad, and looks like a pig and is fat. Etc?
Soos will be revealed as the Big Bad.His Idiot Man Child persona is likely a bit of Obfuscating Stupidity, especially since Dipper says in the first episode that Soos is usually right. Unlike some of the other characters, he has rat-like teeth, a possible hint at a duplicitous nature. And was his discovery of the Wax figures the fortuitous accident he claimed, or was he actually looking for something else, such as Stan's secret vending machine entrance?
Uncle Stan is somehow related to Mr. Krabs.Both are greedy, mentor-like figures, and Jerks With A Heart Of Gold.
The book was written by John Winchester.John discovered Gravity falls and, amongst all the weirdness he encountered there, he left the town, leaving the book behind and deciding the town was far beyond his abilities. The book was hidden in the forest so no one could find it and connect it to him, forcing him into a job he will never be able to complete.
The Cryptogram does not mean anything.The writer of the book was one of the first few people Stan managed to con into the Mystery Shack. The cryptogram, "STAN IS NOT WHAT HE SEEMS" was just the writer suspecting that there was nothing important in the shack, whether he though Stan was distracting him or was just a con man is unknown.
Gravity Falls is an American Gensokyo.And everyone there is a Youkai. Dipper and Mabel are de facto Youkai busters, solving potential incidents. The book is similar to the side material, explaining to the reader about the native species. The reason the Boy-to-Girl ratio is normal is because of the Manotaur's existence.
Gravity Falls takes place in the same universe as John Dies at the End.We know that Undisclosed is special, being a sort of town-sized portal to hell, but there's no reason why it has to be the only one. Gravity Falls's wacky supernatural shenanigans, like Undisclosed's, are due to a portion of the populace using soy sauce and the presence of doors to other dimensions. One citizen we can be sure is on the sauce is the old man from Gobblewonker: Single-handedly building insanely-complicated models of monsters that might in fact exist? Sounds a lot like what Big Jim used to do in his basement... Also, I like to think that at some point Dipper was at the very least one of the many people who e-mailed Dave and/or John with a crazy story or two, since between his snarkiness and straight man role to his crazy ditz of a partner in crime he's like a pint-sized, more innocent version of Dave himself.
At some point, Gideon will capture Dipper and hold him hostage to blackmail Mabel into going out with him again.It's the perfect scheme. Is it weird that I really want to see this? Mostly to see what Dipper would do, and also because I really want to see Mabel go absolutely nuts on that little twerp.
Soos was right.The mailman will really turn out to be a werewolf, or were-something.
Stan is a Plumber or a universe equivalent.The pyramid man seems to have a similar bow tie and hat to Grunkle Stan, and he is not what he seems apparently.
Symbols around the eye of providence from the opening are some kind of occult symbols stuck in Gravity Falls residents' subconsciousSo they put it on their clothes. Several Mabel's sweaters has symbols (star, llama) - in "Headhunters" she was knitting, so she could've made them herself, or whoever made them is also affected. There's also a tree from Dipper's hat and broken heart from one of teenagers' shirt. It may be coats of arms of families who ruled Gravity Falls earlier. And tree from Dipper's hat could be meant to be pine, so Pines could be one of such families.
Grunkle Stan is in wayyyyy deep in whatever's really going on in Gravity Falls.I realize this is super obvious, so I'm using this space to round up the evidence. There's the secret passage behind the vending machine, of course, but in "Dipper Vs. Manliness" we can see part of a tattoo on his right shoulder blade. I'd bet my lunch money there are a lot more little clues to come this season.
An upcoming episode will feature the merpeople of Gravity Falls.There's a picture in the opening credits that could be a mer... thing, and we already know that some- if not all- of the pictures are significant, from Gideon and the Gnomes appearing. Merpeople 'living in the water' where mentioned in Dipper vs Manliness by one of the Manotaurs.
There is going to be a time traveler in an upcoming episode.Aside from the obvious—episode 9 is called 'The Time Traveler's Pig'—there's a man who keeps popping up repeatedly in the background, as one of Dipper's suspects in episode 3, and in one of the photo's in the intro.
The Multibear was testing Dipper.Took a Level in Badass or not, Dipper being able to defeat the Multibear that easily seems implausible, even by the standards of this show. The Manotaurs were bigger, stronger and more well-trained than Dipper. How likely is it that they should fail to defeat a physically stronger enemy where Dipper succeeded? Upon realizing that its latest challenger was a human child, the Multibear decided that Dipper might still be redeemable, and let him win just to test his moral fiber. What the Multibear would've done if Dipper had failed the test, is anyone's guess. But it's unlikely that it would've allowed itself to get killed.
The whole town is in on it.The whole town, or most of Gravity Falls knows about at least some of the supernatural occurrences:
Marginally related to that, EVERYTHING—that is, all the supernatural stuff—is/will be connected somehow, perhaps in the finale of the first season.It kinda jumps around all over the place—Gnomes! Ghosts! A time traveler! Living waxed figures—-to the extent that a troper can't help but feel something will come out of it.
The town was once visited by The League of Extraordinary Gentlemen.They did visit Twin Peaks before, and that's in Oregon as well... plus what's to say Dipper might form a League of his own when he becomes more badass?
Gideon will make a Heel-Face Turn.And the Mystic Amulet is going to be a Chekhov's Gun in defeating the real Big Bad of Gravity Falls.
The "Charm" in Dipper's book...Is a magnifying glass, not really a charm that gives the wearer mystic powers. But it might reveal things not visible to human eyes.
Wendy is/will be the mother of Marceline the Vampire Queen.They share a similar physique and attitude. Given the amount of crazy shit in both shows, it doesn't seem unlikely that Hunson Abadeer might visit there, and find a mate. And who better than the sole female employee of the Mystery Shack? The great Mushroom war begins roughly 10-20 years after the current time of the story in Gravity Falls.
The amulets have different abilities.Assuming every volume has an amulet with it, and every volume is different. The amulets were likely placed away separately because when combined they might be too powerful.
The first machine's switch did something else.The machine Dipper found in the tree had two switches. He flicked the first one on and off, but that did nothing. The second one opened the trapdoor. So the question is, what did the first one do?
Gideon will form a League of Evil Exes.Granted, the only other identified possible members are a bunch of Gnomes, but...
Grunkle Stan is actually trying to prevent a destructive supernatural/alien force from getting out.The force is kept locked in the bunker behind the vending machine. Grunkle Stan just checks on it on a regular basis. Someone will get into it, either Gideon hoping to control the power or someone else (perhaps Dipper) who mistakenly believes that Grunkle Stan is the bad guy.
There are eight journals in Gravity Falls.The number eight is repeated multiple times through out the series, in the form of the numeral, it being mentioned, the letter H (the eighth letter in the alphabet), and the infinity symbol. We know that multiple volumes of the journals exist, and is seems like owning all of them could be influential to the plot. So it's possible that there could be eight journals, and the ensuing Myth Arc could play out like slightly kid-friendlier version of the Survival Game from Mirai Nikki.
Soos is short for Jesus.Pronounced the Spanish way, of course (hay-SOOS).
Double Pacifica.When Wendy is waiting for the bathroom, we see Pacifica still on the dance floor, but then Pacifica comes out of the bathroom. This isn't a continuity error. Pacifica found and used the copier, and the Pacifica that came out of the bathroom was a clone. Note how she has duller colours than normal.
The Northwest family has a history of constipation problems.This is why Pacifica was looking so frustrated when she came out of the bathroom. It's also the reason why her forefather tried eating a tree - He was desperate for a source of more fiber. (The Double Pacifica theory fits into this, with one small modification: It was the real Pacifica who went to the bathroom. She knew that she might have to spend some time there, so she made a clone of herself to keep people's attention on the dance floor)
The "Adam WarRock Gravity Falls Theme" will be featured in the show at some point.Alex Hirsh knows that it exists and claims to have liked it.
Each numbered volume is actually a part of one big book.Basically, whoever wrote the book found some way to split the book into multiple volumes to keep it from falling into the wrong hands.
Pacifica might team up with the Pines Siblings.How many episodes, I am not sure.
Pacifica will team up with Gideon.Pacifica could be considered Mabel's Sitcom Arch-Nemesis, while Gideon is one to Dipper (Although less sitcom-y, with all this attempted murder and stuff). Of course this would take some Motive Decay for Gideon to team up with Mabel's enemy, but hey - dude's crazy. He and Pacifica can even start a relationship - two rich sociopathic narcissists.
The Book is alive.In the first episode, it was actually trying to warn Dipper that he was facing gnomes rather than zombies.
Dipper clones 3 and 4 will return.After stealing the bike, 3 & 4 are never again seen. While it might be difficult for the two to survive in a world full of liquids, they were not confirmed to be dissolved.
Each volume of the book has instructions on making some powerful item.The one Lil' Gideon has shows how to acquire the amulet that gives psychic abilities. Each volume of the book shows how to make certain items, each one giving a different power. Having every item at once makes the user pretty unstoppable. Powers given by the other items may include invisibility, mind control, and shape shifting.
Each volume of the book has a different "topic" on the supernatural.The one Dipper found features information about supernatural beings. The one Gideon has features instructions on creating magical artifacts, or perhaps instructions on powers and forms of attack. The other book(s), which hasn't/haven't been found yet, follow(s) different topics. This would make it possible for there to be more than three volumes, despite Volume 3 being ominously unfinished.
Dipper will meet the author of the Books, who will beg him to stop his crusade and forget about the unknown.Dipper's answer won't be shown directly. We then see him living a completely ordinary life, writing and doodling innocently in a journal, and putting it down to run off and play... but then we see the journal's cover: a six-fingered hand marked with the number 4.
An ambitious six-season story arc has been planned.Each season will cover one summer. This will mirror the six years the author of the Books spent researching Gravity Falls.
Wendy is not as old as she claims she is.Wendy is/was freakishly tall and has been for quite a while, as shown in "Double Dipper". It's not unreasonable to suppose she may be a year or two younger then she claims she is. Which, incidentally, means Dipper might have a better shot with her then he thinks.
Dipper and Mabel are Thomas Jefferson.In "Irrational Treasure", one of the secrets◊ is "President Jefferson was just two kids on each other's shoulders in a trench coat", and considering the next episode is about time travel...
Dipper's birth name is Abel.And it's going to be very important for one reason or another.
Dipper's birth name is Alex.And it's not that important.
Dipper's birth name is Alejandro.After all, it is the Spanish equivalent of Alexander, isn't it? And Alex is short for Alexander, which means it would be a stealth way of naming Dipper after the creator, without technically doing so.
Dipper will find the scary skull from the opening credits.Now, after the pig appeared, it seems inevitable.
The President's Key will be a Chekhov's Gun.Again, inevitable.
Disneyland will make a Gravity Falls ride.Perhaps the most inevitable thing of all. Most likely it will be relegated to California Adventures due to not exactly fitting the "Disneyland Experience", but there's seriously no reason not to:
Stan is somehow involved with SCP Foundation.Behind the vending machine is perhaps the SCP Foundation warehouse.
The show shares a universe with Puzzle Agent.The feel and humor of the two series is pretty similar, and while we haven't seen any supernatural beings in Scoggins, Minnesota yet, there's so much unexplained there that they might possibly exist.
The Time Baby is related to that creepy floating Giant Baby Head in Phineas and Ferb.And it may be an impetus for a crossover per a previous WMG.
Pacifica likes Dipper.Pacifica has picked on Stan and Mabel, but not Dipper. When Mabel saw Waddles, Pacifica joked that Waddles was "Mabel's real twin," suggesting Mabel is a pig, but not Dipper. The pig episode came after "Irrational Treasure", so she may have respected Dipper for defending his sister, being more serious, or for giving into his need for revenge.
There will be a falling out between Dipper and Mabel.The author of 3 said not to trust anyone, but Dipper learned he can trust others. This will be Dipper's undoing: he will be (possibly accidentally) betrayed by Mabel or someone close to him, causing him to rip out the message about trust he wrote.
There will be an episode dealing with an alien invasion.And it will have tons of references to famous sci-fi movies like War of the Worlds and Invasion of the Body Snatchers.
The series is a prequel to Left 4 Dead.Most of the cast are the special infected. As listed by /co/:
Waddles the Pig is the key to unlock the secrets of Gravity Falls.Somehow.
The fair was a fixed point in time.Notice how hard it was to keep Wendy from getting the black eye? And how the only way to get it to work is to keep Mabel from her pig? The universe NEEDS Mabel to have that pig and for Dipper to fail at that date. When Dipper went around it, that's when bad things started to happen.
That pyramid thing's name is Bewarb.You know that pyramid thing that shows up at the end of the show's intro? The mosquitoes in the first episode were trying to warn Dipper about him, hence Bewarb.
STAN IS NOT WHAT HE SEEMS is misleading.Everyone seems to think that he might be evil. Maybe the message means that he's a merman or something.
Gideon's mother died.We never see Gideon's mom, nor is she ever mentioned, but his dad has a wedding ring. If she died, it could be a reason why he's not quite right in the head.
Gideon killed his mother.As an alternate to the above theory, Gideon's mother is dead, but he killed her. He uses mind control on his father so he would forget. Gideon's mother knew about the amulet and didn't like how her son was becoming corrupted so she attempted to destroy it, but he killed her, possibly on accident, possibly on purpose, when she tried to destroy it.
This story is canon.The show we see is Mabel's Dream World where Stan isn't abusive, Soos didn't go to jail, Dipper wasn't murdered, and Wendy actually gave a shit about the twins. Before the incident Mabel was a fan of fantasy which explains the weird creatures and such. Gravity Falls is nothing more than a dream a teenage girl pretends to live in to cope with her abuse. Stan wanting Mabel to put on a blindfold and get in his car is another hint, she still loves the dream version of him, but will never forget what he did to her and her baby in reality.
Blubs and Durland are a gay couple.The subtext may be unintentional but it's becoming quite blatant.
Dipper and Mabel's birthday is February 29th.Admit it, it makes sense. When Dipper told Mabel they were going to pose as thirteen-year-olds, she asked, "Is it a leap year?" She associates leap years with their birthday. This would mean they were born in 2000. It would also make them Pisces, which makes sense for Mabel — less so for Dipper. This would tie in with Gilbert and Sullivan's opera The Pirates of Penzance, which features a hero whose birthday is February 29th and a heroine named MABEL STA Nley.
Dipper's first name is Kane.Trust no one, after all.
Alternatively, Dipper is a direct descendant of Cain.
Mabel was supposed to find the book.Weird stuff is always gravitating toward her—the gnomes and Gideon, for instance—and, in The Inconveniencing, she was possessed, rather than 'punished' by the ghosts. In Irrational Treasure, she was even the one to solve the (ahem) mystery of Gravity Falls' founder. It's easy to imagine her stumbling across a metal tree and just rolling with it. On a side note, she would have a harder time getting the "Trust no one" thing than Dipper did, potentially explaining why it was written multiple times on one page—to drive the message .
Each volume of the book has a different author.
Old Man McGucket is (Even) Older Than He Looks.Fertillia's baby in the Oregon Trail sequence of "Time Traveler's Pig" has a band-aid on the left side of its chin too.
The books were co-authored.Though the easy distinction is ink color, there are two sets of handwriting in the book. One of the Freeze Frame Bonuses from the first episode includes a game of tic-tac-toe in red ink on the "Giant Vampire Bats" page, suggesting that more than one person had access to it before Dipper found it. The person writing in red ink usually only draws symbols in the margins (or writes reminders about overdue library books...), but sometimes he or she crosses out existing information or writes relevant notes, like an editor would. Perhaps "He" got to one of the authors, stopping work on the third book, and inspiring the remaining author to go back and add "TRUST NO ONE" once more in big, bold letters before hiding it.
Dipper Goes To Taco Bell is canon.During the events of the time travel episode Dipper and Mabel travel a few days into the future and see their future selves murdered by the Taco Bell guy. They go to the photocopier from "Double Dipper" and clone copies of themselves and go to the day the original twins died and leave them there. Every episode after the time travel one features the clone Dipper and Mabel and Soos will never know he ate his friends.
The Slender Man will appear.There was a famous shopped pic of Slendy in the background, and even Word of God commented on it. Maybe it'll be an Ascended Meme.
Some theories about this guy◊ in "Irrational Treasure".
Wendy is based on the creator's wife.Wendy, according to the Trivia page, is based on someone that the creator, Alex Hirsch, knows. I believe it may be his wife. Of course he hasn't said who she's based on yet; that would be a massive spoiler if Wendy and Dipper ever got together at/near the end of the series.
Mostly every villain faced in the show will team up to make a Legion of Doom in the season finale.Many villains of the individual episodes vow revenge, and imply that they'd be back.
Gravity Falls is actually Heaven, a la Narnia.What if Dipper and Mabel died on their way to the real Gravity Falls and are instead in a sort of heaven? It would definitely explain all the weird going-ons. (Mabel's mind in action, maybe?)
Mabel is a imperfect cross-dressing clone of Dipper send from a parallel universe to stop Grunkle Stan from breeding gnomes with Manotaurs.Look into your heart, you know it must be true.
The Giant Caterpillar that Dipper accidentally expands will make a comeback in the season finale.It's gonna happen, you'll see.
Soos will be the next Mr. Mystery."Soon..."
Gideon knows about Stan's secret room.At the end of Little Dipper, Gideon mentions the Mystery Shack hiding a secret. This likely means the mysterious room that Stan was seen entering in episode one.
Grenda's uncle gave her one of his lizards.And his name was Alex.
Time Baby will be the series' Big Bad.In addition to being shown twice in "The Time Traveler's Pig" with destructive psychic powers (and doing so in an apocalyptic future), the "Northwest Coverup" document from "Irrational Treasure" mentions, among other things, a time-devouring baby from another dimension who is frozen in the Antarctic.
the pyramid guy (aka Bill Cipher) is the big bad/big goodCome on, he seems to be the center of the whole mess. Maybe he'll help the others out. He's important anyway. Or...
there's an even bigger bad behind the scenes.In the opening credits picture of the pyramid, there's a bunch of letters somewhere on the left. It's binary code for " the word smuggler lives." Also, if you take a look at the whole picture from the out takes (the one with the crossed out eye) there's a bunch of numbers which have been covered in the red paint used to cross out the eye. Pretty sure its in the other journal pages and maybe in the other important bits of the show. So maybe the big bad isn't actually Bill Ciphers, but actually the word smuggler, as he seems to be terrifying the socks off the author. Or he'll just be another big bad in the later seasons. He'll be really important, anyway.
Book 3 was written in defense against book 2.In "Little Dipper", Gideon mentions one of the entries in book 2 to be "Zombie attack", while book 3 mentions how to recognize a zombie. It's likely that the author wanted to protect the owner of 3 from such attacks.
Grunkle Stan wrote the books.Stan wrote all of the books while he was younger after Mabel and Dipper made a bunch of strange noises outside his one day. After which, he began to study the area more closely, and things went completely downhill from there. As a result, he wrote the books (however many there are) as a journal to keep a record of what he found so that he wouldn't seem so crazy. He also has the first book, disguised as a diary or some other type of book.
A relative of Gideon's, possibly his grandfather, co-wrote the books with Stan.Stan and Gideon's relative were friends, as well as fans of the supernatural and the strange. Together they wrote the books containing the secrets of Gravity Falls. But at some point, Gideon's relative grew power hungry. He knew that he could use the forces of Gravity Falls to take as much power and control as he wanted. This was too corrupt even by Stan's standards, so he set to stop Gideon's relative by hiding the thing that would have given him the power. Hence why 3 has the "trust no one" message. The part about Stan not being what he seems was written by Gideon's grandfather, who assumed that Stan also wanted power. This caused a rift between the two and Stan attempted to hide the books. Gideon's relative managed to find 2, but by then he was too old and weak to do anything. He passed the book, and the legacy, on to Gideon because a child could be more easily influenced. Or, alternately...
Stan is part of a secret society, as was Gideon's relative, dedicated to uncovering the secrets of Gravity Falls.There are/were many other members and all wrote what they found. Different members had different priorities, so the different books might end up focusing on different things. Gideon's relative was obsessed with power and his book focused on how to use the things and creatures found in Gravity Falls to obtain power. Stan may or may not have helped write 3, however, whoever did help write it intended for it to be used, in part, as a guide on how to protect oneself not just from the creatures of Gravity Falls, but from whoever possessed 2 and would try to use the information for evil. The pages about trusting no one were mostly or entirely inspired by Gideon's relative. The bit about Stan not being what he seemed refer to him holding a huge secret, not necessarily that he's evil.
An invisible wizard will appear in a later episode.Episode 11: THE INVISIBLE WIZARD IS WATCHING.
Mabel is taller than Dipper because of what happened in "The Time Traveler's Pig".Mabel spent at least a month being upset over losing Waddles, and since she seems to remember everything at the end of the episode she must have gone back with Dipper for the final change. That means that she's a month older than her twin, which is why she is slightly taller.
The creature from the upcoming episode "Summerween" is a reference to the Slender Man.An earlier post mentioned that a future episode would contain a reference to the famous screenshot with the Slender Man photoshopped into the background. Think about it: A tall, humanoid abomination with multiple arms who (based on the trailer) seems to have a thing for kidnapping children. Sound like anyone we know?
Gideon grows up to be Gideon.He's already got some of the characteristics: He's a malicious business tycoon, he has an affinity for supernatural powers, and he's very persistent about getting the girls he wants. If he moves to New York and makes some changes to his appearance, he could easily turn out to be Gideon Graves.
Grenda and Candy will become Sixth Rangers to Dipper and Mabel.Obviously, they won't appear in every episode but the episodes where they appear will have them help out in some way.
The shipping focus will eventually shift to Dipper/Candy.Am I seriously the only one who noticed Candy's reaction to the Trickster's ultimatum Clinging to Dipper's arm while cowering in fear? C'mon, Dipper's not gonna persue Wendy forever. . .
Dipper's first name is Roderick.That's why Quentin Trembley called him "Roderick", Mabel told him Dipper's real name.
Candy and Grenda are vampires.They only appear in two episodes: "Double Dipper" and "Summerween". Both episodes took place at night. Coincidence?
Soos is the stepson (or at least is an adoptive son) of Grunkle Stan.That's why Soos put on Stan's fez and said "One day,". This was mentioned before in this forum, but this explains some other stuff.
Gorney, from "Summerween" is Grenda's little brother.Think about it. When Gorney was supposedly eaten by the Summerween Trickster, She was the only one who said his name. Luckily, Gorney was all right in the end.
Gravity Falls doesn't actually exist.Or more specifically, it isn't an official village. After Trembly founded the area, due to people no longer viewing him as an official president (Despite him still being one due to not signing an official resignation), they ignored the town. So officially, Gravity Falls doesn't exist.
Gravity Falls is a computer simulation.Mr and Mrs Pines were concerned that their children were spending too much time on the computer, so they sent them INTO the computer. The kids are inside a prototype video game where Waddles of all things was the intended protagonist. Thanks to Mr. Pines’ near-perfect programing and Mrs. Pines astounding graphics, the kids think this is all very real.
Li'l Gideon is a demon.His true name in an anagram of the one he uses. His “Parents” are an older couple who made a deal with the devil for a child. Satan sent Gideon, and he’s been manipulating them ever since.
Soos, one way or another, is involved with Gravity Falls' secret.I know this might be obvious...but when think about it, Soos seems to have some knowledge on certain things, or isn't too surprised by the supernatural activity in Gravity Falls. Some examples:
At one point, Dipper will have to choose between saving Mabel's life or Wendy's life.Or, a third option: He will need to sacrifice himself to save them both...
Pacifica's parents are the Big Bads of the show.They will take revenge upon Dipper for exposing their secret to their daughter and there will be a big TV movie about it.
Gideon's mom killed him.He's a ghost how else would he know about all the crazy shit that's going down? It would also explain why Gideon's mom is kinda... well you know.
Gravity Falls is a purgatory for aborted/rejected Disney characters a la Epic Mickey.It's Wasteland 2.0. Let's take a look:
The photos in the credits sequence will change for Season 2 to feature villains for that season's episodes.
The Wax figures murdered Wax Abraham Lincoln because he didn't want to go through with the murder plot.
A brief history of the pyramid guy.The Pyramid Guy was fighting the Time Baby for some Applied Phlebotinum in the other dimension. They then got knocked into our dimension by the Phlebotinum's effect. The Pyramid Guy then landed in Washington DC. After forming a secret society, he took the body of Quentin Trembley. Although all his actions had meaning (like making peace with the Time Baby by appointing babies to the supreme court), they were thought to be silly, so he left with his Phlebotinum for Gravity Falls. His Phlebotinum had unusual effects on the area, so he needed something to clean it up. He tried using Old Man McGucket to clean the mess up, but failed, so he recruited another society, consisting of Stan and Gideon's relative. He required them to go and get the items seen around him in the mysterious image of the Pyramid Guy at the end of the opening, and wrote Book 1 about the quest. The objects would heal Gravity Falls. However, during their next mission to battle the creatures, Gideon's ancestor came up with an idea to battle them with other mystical artifacts and wrote it in Book #2. Stan didn't like that idea, so he kicked Gideon's ancestor out. Stan then wrote Book #3, but the hid it because Gideon's relative tried to stop him with his idea. The Pyramid Guy, fearing something similar might happen to Stan, brainwashed him and gave the secret identity of a con man , and used his merchandise to heal Gravity Falls. The Pyramid Guy created Soos to make sure it went perfect, hence Soos being a Cloudcuckoolander like McGucket and Trembley. However, when it came time to intrust the secrets to someone else, the Pyramid Guy exited Soos and told Stan somebody must inherit the books and then hid in a vending machine. So Dipper and Mabel came, and their mission became successful. To make sure that Dipper and Mabel stuck with each other, The Pyramid Guy created Waddles. This enabled Dipper to stick with Mabel instead of Wendy. Eventually, the Time Baby escaped, and the Pyramid Guy, after being freed by Dipper and Mabel, time traveled back as Blenidin Blandin to check on Dipper, Mabel, and Waddles.
Dipper and Mabel are in a Truman Show Plot.Stan needed to make them like their trip, so he set up a scheme in which Dipper and Mabel would like their town.
Dipper is the heir to the Hokuto Shinken.His birthmark says it all.
Gideon is cursed with 7 x [however many mirrors he broke] years worth of bad luck.Thus dooming himself to Failure Is the Only Option.
Gravity Falls is a literal Ghost Town.Once someone enters Gravity Falls, they can never go out, because while there are many ways to stumble upon it, it becomes very difficult to exit. Remember how in Irrational Treasure Dipper, Mabel, Trembley and the Cops were on their way to Washington, but never made it? And how the cops were apparently gone for the duration of Time Traveler's Pig but back during Summerween? That's because they never actually left Gravity Falls. Also, every tourist we see entering the Shack can still be seen in the town in later episodes, but doing different things. It's the kind of place that gives people goosebumps because people go into the woods, but never seem to come out.
Stan lives a very kinky double life
Dipper is Disney’s shot at DibThey’re both into mysteries, and they both have big heads and said there arms are like noodles.
Dipper is the sacrificial lamb, and Mabel is the one who will (at least try to) kill him.We don't know Dipper's real name, Stan has a sister named Jan, and twins seem to run in the family. So having similar names may be tradition as well. Mabel is literally one letter away from being Abel, who was killed by his older sibling in the Bible. Dipper's real name may be Abel, and it would make sense based on what we've been shown so far. And finally, the book says not to trust anyone. When Dipper brings this up to Mabel, her reaction is along the lines of "Aw, you can't trust me?" The first person the show dismisses the warning in favor for someone Dipper undoubtedly can trust is Mabel. Though this won't be too much of a setback for Dipper in the end, as there are plenty of (some only theorized right now) undead who seem totally cool with it.
The brain creature seen in the ice machine in "The Inconveniencing" is somehow part of the greater mystery of Gravity Falls. It has some sort of connection to ice, cold places, or even ice machines.
A little on Stan's historyStan used to be a lot like Dipper. To make sure someone will know how to defend themselves, he wrote the books (however many there are) One of them (probably 1) is in that secret room of his. That secret Gideon talked about? He either meant Dipper's book, Stan's, or something else in that room. Plus, ever wonder if there was some other reason he locked up the wax guys? Furthermore, he's well aware of the supernatural things going on in that town, and of Dipper & Mable's adventures, but he pretends not to for their own safety. (Otherwise, he's pretty much exactly how he acts.)
Gravity Falls will have a console video game.And it will be a point and click adventure game. Because that genre would suit Gravity Falls perfectly.
Dipper and Mabel are descendants of Quentin Trembley.Why was the Quentin Trembley cover-up such a big deal? Because it was a shameful chapter in American history, right? There's more to that. A mysterious power lies within the Trembley bloodline, which could possibly have been the reason for Trembley to have been such an eccentric individual (either it corrupted him mentally as a side effect, or he feigned insanity to hide it from the crowds). It's probable that the people of Gravity Falls want to harness this power, and Trembley probably froze himself to stop this very thing from happening. In the meantime, a son or daughter of Trembley went on to live their own life, continuing the Trembley bloodline under the radar of the general public, eventually going down the line to one of Dipper and Mabel's parents, and then to the twins themselves. Why do Dipper and Mabel attract so much danger from outside forces? Maybe it lures monsters to signal Gravity Falls's higher-ups to their whereabouts and thus allow them to harness Trembley's power. And since Stan is not what he seems, chances are there's a reason the twins are in Gravity Falls with him instead of a more suitable vacation spot, and it involves him.
Pacifica would have taken good care of Waddles.Mabel, Waddles, and the audience just assume Pacifica would mistreat or eat Waddles because we know her as an Alpha Bitch, but we don't know that for sure. It's entirely possible Pacifica thought Waddles was cute and wanted a pet, just like Mabel, but didn't try to win him at that moment because she didn't want her friends to know she likes "ugly" or "dirty" farm animals. So at some point in Pacifica got away from her friends and went to win Waddles, but since Mabel got him she got a chicken instead. Both Waddles and the chicken don't like her, implying it's because she's evil, but she could just have bad luck with animals.
Gideon is older than he looksHe's actually Stan's contemporary, but either because of a curse or self-inflicted, he was regressed to a child, and uses his appearance to manipulate the town to do his bidding. The family he stays with is not his; he used the amulet to brainwash them into believing he was their son. Although their mother is well aware that he's not her child, she complies anyway, knowing what he's capable of (which is why she always looks so terrified). Moreover, Gideon uses his psychic persona to investigate the events surrounding Gravity Falls without arising suspicion, looking for the other books to gain enough power to rule over the town.
The book was written by a girl.
Soos is fantastically wealthy.And there will be an episode where he invites Dipper and Mabel to his home and they find it's full of cool toys and geek stuff. Yet he thinks that none of it compares to the Mystery Shack, and works there because it was the most fun he ever had as a kid and he wants to repay Stan for the good times. However, he keeps his wealth a secret from Stan because he thinks the shoddy look is part of the charm, so Stan just thinks Soos is a weirdo that doesn't mind not being paid.
There is 6 Books.The hand in the book cover has 6 fingers. And one of those books might be the one which is literally just a log.
There will be an episode where Dipper and Mabel get transported into a TV set.One day, Dipper and Mabel find a mysterious TV remote. Then all of a sudden, the remote zapped them into the TV. From there, Dipper and Mabel visit parodies of TV shows like:
Mabel will lose the braces.And with them, Chickification will happen. I've seen enough cartoons with identifiable geeky characters to know where she's going...
Mabel, like Dipper, has a birthmark .But it is not that.... "cool".
Dipper and Mabel will meet Randy Cunningham.I know everyone is interested in a crossover with Phineas and Ferb, but what about the Mystery Twins meeting the Norrisville Ninja? Don't tell me I'm the only one who wants to see that happen!
Merfolk can change shape.The merfolk seen in "The Deep End" (Mermando and his family) look very different from the mercreature seen in one of the pictures in the opening.◊ There could either be subcategories of mercreatures, or they can perhaps make themselves look humanlike, and the more grotesque "creature from the black lagoon" look is their actual appearance. ...could cause Mabel to go through some Fridge Horror if that's the case.
Stan knew about the hidden room.Pretty obvious as he only seemed annoyed at it being found. Combined with him immediately going for and hiding something only he in the Mystery Shack would have any need of, those glasses on the desk. Big Bad who conjured up all the mysteries in Gravity Falls.
In "Carpet Diem", the body-swapped characters' Voices Are Mental only to us, the viewers.That explains why everyone else doesn't notice that Dipper and Mabel are part of a "Freaky Friday" Flip.
Wendy is a siren and the old gnome queenShe impressed the gnomes, and the gnomes decided to marry her. However, she was found by Robbie and plucked out of the forest, and so she decided to try to undermine the Mystery Shack and isolate the magical thing there. The gnomes wound up using Wendy as a model for Norman. Also, Dipper said he doesn't trust big hair and was right, so why should he trust Wendy?
Dipper and Mabel are bullied and/or have no friends at their home.This is why in "Double Dipper" Mabel seemed so happy to have friends that actually wanted to hang out with her.
Candy Chiu has a crush on DipperShe is seen clinging to him in Summerween, and in Carpet Diem she chooses to switch bodies with him.
Stan invented the body-switching carpet.Think about it for a second. The calendar in the room is dated in 1982. In "The Time Traveller's Pig", Dipper and Mabel are transported back to (what's implied to be) that time at one point during their time-travel montage. They run past the Shack back when it was just Stan's house, and he peeks out the door. In that scene, Stan is wearing the same glasses he picks up and hides in "Carpet Diem" when the secret room is found. Perhaps he invented and forgot about the carpet when it failed to work the way he planned, and he abandoned it in the room that was later discovered by Soos. It explains "Wow, this carpet is amazing!" "Yeah, if you're into things that are terrible." and why Stan happily obliges when Dipper asks him to get rid of it at the end of the episode. Also, the carpet is labeled 'Experiment 78', as if there are others. What if his other inventions are what's hidden in that secret room behind the snack machine? Maybe they're what's making Gravity Falls so weird.
The Gravity Falls Earth eventually becomes Ooo.The Summerween Trickster seems to be an amorphous mass of SOMETHING that craves candy and flesh. We have seen in Adventure Time that candy people can absorb "candy biomass" to heal and grow, and both the candy zombies and Peppermint Butler have expressed cravings for human flesh.
Stan's ramblings about the apocalypse are more than it seems.As said by many people when thinking up theories about him, "Stan is not what he seems." Stan is mysteriously and calmly expecting the apocalypse to happen. Soon enough that he's stocking up on food. Stan doesn't really seem like the kind of guy to plan ahead several years, so it's reasonable to assume he expects it to happen sometime soon. Like, within four episodes soon, the number of episodes remaining in this season. And it has been confirmed that something big is going to happen by the 21st episode. And now Robbie has reason to hate Dipper. Robbie. The guy the fandom has been speculating as a zombie since his first appearance. And what's one of the things Lil' Gideon comments on being hard to control? Zombies. The symbol as of yet only shown on his jacket is in the 3rd book. My current theory is that it will be a zombie apocalypse, as they are the only creature in the book that Dipper paid special attention to, that has not yet been shown to either Dipper or Mabel throughout the series whether onscreen or as a casual mention of them. And that Stan knows it's coming. Possibly because of whatever the hell he has behind the snack machine.
The Season One finale, or at least an important episode, will be Dipper vs Mabel.But it's not because of a mere sibling rivalry, oh no; it's for something greater, like a valuable artifact that they could kill each other over. Think about it; Mabel sacrifices for the needs of the many (Sev'Ral Times, Mermando and his family, Waddles) while Dipper sacrifices for the needs of the few (Himself). Whenever Dipper had a chance for Wendy, Mabel's kindness and compassion got in the way. Dipper is becoming more like Grunkle Stan, while Mabel becomes the exact opposite. If Dipper and Mabel ever have a climatic showdown, Dipper will represent his isolation by being alone using only Book 3's paranormal information and his wits, while Mabel will represent teamwork and have Candy and Grenda (and a grappling hook) by her side.
Grunkle Stan is Satan.First of all, the name. Second, the warning about him. Third, in "Boys Crazy", he predicts the apocalypse in the near future, and he seems to look forward to it.
Grenda will grow up to be Connie from Brickleberry.
Grunkle Stan is a reincarnation of Stan MarshBecause, why the heck not.
Robbie has one of the booksIt would definitely explain how he was able to create that mind control song in the first place.
There is an unspoken agreement among the town's residents not to discuss the things that go on there.A lot of the people in the town seem aware that paranormal things happen, but most don't make them out to be a big deal. But Dipper, an outsider, reacts to these things with surprise, indicating that people outside the town aren't aware of those things. For whatever reason, the townsfolk have decided not to make a big deal about these things to the rest of the world. Maybe out of some sort of respect for the supernatural, or they don't want people crowding over and messing things up.
Gravity Falls sits on top of a Hellmouth.Thus attracting all sorts of strange supernatural activity to the area.
The members of Sev'ral Timez will make brief appearances in future episodes.Mostly them doing silly stuff in the background.
In a future episode, Dipper will turn into a werewolf.His wolf-boy costume in "Boss Mabel" and the way a Wolf (Coyote?) gnawed on his leg in "Carpet Diem" could be foreshadowing. Of course, if it does happen, he'll probably be back to normal by the end of the episode.
The Sev'ral Times song asking "Girl, why you acting so cray-cray?" ...... is inspired by their favorite talk show host — the one from "Fight Fighters".
There are actually ten books...... and each of the symbols on the last frame of the opening intro for the show represents the owner ( or destined owner for each one. So far: Dipper (tree symbol(confirmed)) has the third volume. Stan (glasses(confirmed)) most likely has the first volume. Gideon (pentagram) has the second volume. Robbie (broken heart or ice bag) has a volume. Mabel (shooting star(confirmed)) will receive a volume. Soos (question mark(confirmed))has or will receive a volume. Grenda (llama) has or will receive a volume. Author (original owner of the fez) wrote a volume. The Pyramid Man is the controller/author/owner of all the volumes.
Gideon will be a Not-So-Harmless VillainMore wishful thinking, but still...
There are two MabelsIn the image at the end of the intro, each symbol around the Pyramid represents one of the characters. However, two symbols have appeared only on Mabel's sweaters. Why is Mabel assigned two symbols? It could be possible that there is a doppelganger occasionally taking the place of the real Mabel.
Mabel has Asperger's Syndrome.She has No Indoor Voice and no sense of personal space. She is often unaware of when she is being annoying, offensive, mean, or upsetting. The friends she is able to make are very nice people and equally eccentric, though not to the extent of herself. She is very emotional and easily upset. She has the tendency to not understand social cues, and to accidentally startle/sneak up on people. It would not be suprising if she was somewhere on the mild end of the autism spectrum- though given her ability to function in society and do things for herself, she is only very mildly on this spectrum.
Blendin Blandin later went insane and died, and his soul was later reincarnated, minus memories, into another body.After dealing with his scary boss, two annoying kids, and a potentially life-or-death situation involving time anomalies, Blendin Blandin had a nervous breakdown and became emotionally fragile and imbalance. He died young as a result of the stress crushing his immune system. After Blendin Blandin died, there was an apocalypse. The universe of Adventure Time came into existence as a result of this. When Princess Bubblegum attempted to make a person with candy biomass, she somehow caused Blendin Blandin to be reincarnated (minus his memories) into the body of a lemon candy man. In short, Blendin Blandin later became Lemongrab.
Soos will make a Heroic Sacrifice.His name is Jesús and he talked about being a side character who gets killed.
The Invisible Wizard is real.And Grenda was kissing him during the sleepover.
The goat that appears every now and then will turn out to be important.Because nobody suspects the random goat. Also, the goat was looking right at the panel concealing book 3 when it opened, and soon after tried to take the book, or eat it. The llama symbol on the Cipher wheel may be a stylized goat.
Robbie has a very difficult home life.Maybe he's had a Hilariously Abusive Childhood, something that may or may not serve as a Freudian Excuse that explains why he's such a jerkass, and is so fiercely defensive about Wendy when it comes to Dipper's interest in her.
Human-sized hamsters exist in Gravity Falls.That's why the magazine in "Legend of the Gobblewonker" was offering human-sized hamster balls.
Soos is a Bigfoot.In the opening sequence there is a section with trees casting shadows, and an image of a man flashes. When frozen, it resembles Soos. Soos probably wanted to live like the humans did, or was tired of being chased after, so he shaved off all of his hair except for his head hair, which resembles the color of bigfoot hair.
Pacifica will become a Rival Turned Evil in a future episode.It will involve Pacifica coming across an Artifact of Doom and she uses it to get revenge on the Pines for disproving her family's heritage. It ends with an epic battle between Mabel and Pacifica that spoofs Sailor Moon or just anime in general. Also, Pacifica will invoke Evil Is Sexy.
The Stan look-alike in "Time Traveler's Pig" isn't Stan.The shape of his nose and his face is slightly different than the younger Stan seen in "Boyz Crazy". He may be Stan's brother (Dipper and Mabel's grandfather) or even Dipper in the future.
Dipper will cross the Moral Event Horizon in his quest for Wendy.Dipper uses paranormal stuff to forcibly attract Wendy. Examples include him altering fate itself and making clones of himself to do what no human could do on his own in one night, and it's glanced over and viewed as acceptable. When Gideon does it to attract Mabel or accomplish his goals, it's considered immoral and wrong-granted, his usually involve murder, like in his very first episode or in "Little Dipper" where he tries to kill Grunkle Stan, plus he's obviously insane, but Dipper still receives nothing of the sort when he wants to get his way. Dipper will get desperate if Wendy still is upset at him after Boyz Crazy, and use the CD (or something far worse) to get Wendy to love him. Mabel will have to break him out of it, and ends up rescuing Wendy and Dipper from himself. Or, if used in a different way...
Dipper and Gideon will have a Not So Different moment.Near the end of the season, Dipper and Gideon will have a battle over Book #2. Whether it be physical or mental, Gideon will bring up that he's been watching Dipper the whole time and was aware of what he did to get his crush to love him. When he compares this fact to his attempts with Mabel, Dipper will have a Heroic BSOD.
Stan is Pyramid guyThe warning that Stan isn't what he seems is that he isn't human at all, he is somehow related to the pines family and maybe even gave Dipper his intelligence and Mabel her ability to think outside the box, only when they work together can they solve the mysteries and Stan may act like he doesn't believe them, but the bunker under the mystery shack and the fact the pyramid guy has the same hat that can change symbols and no one notices. now pyramid guy maybe the Big Good of the series or the big bad, but i have a feeling since Stan does genuinally love the kids he well turn out to be the big good well something connected to that B*stard Gidion well end up as the big bad
Grenda is transsexual.She identifies as female but is biologically male, hence her deep voice.
The Mystery Shack is sentient.The changes to the shack are not continuity errors, The Mystery Shack is literally changing its appearance based on mood. In fact the building has all sorts of emotions including affection towards Grunkle Stan.
Ice is significant, and is a bad omen for Dipper.The fact that a bag of ice is one of the symbols one the page of the book visible in the opening indicates that it is significant somehow. It's a bad omen for Dipper because the only time ice/bags of ice show up so far, something unpleasant happens to Dipper:
Scooby-Doo! Mystery Incorporated will be referenced at one pointSlightly possible, with the similarities of the two shows (kids find horrible mystery/conspiracy in a podunk town).
Next time Stan and Gideon are alone together, they'll have a little "chat" that takes us further into the shows mysteriesMaybe something like...
When you've lived in Gravity Falls for a certain period of time, you become one of its creatures.This might be a long shot, but it fits when you think about it. Wendy is a Siren (explaining why everyone is so attracted to her), Robbie is a zombie or a vampire, Soos is Bigfoot, etcetera. Peoples' outward appearances stay the same to everyone, including themselves. No one realizes what's going on except Stan (and/or possibly Gideon). This is the secret of Gravity Falls, and if Dipper and Mabel stay for too long, the same will happen to them.
There is a Book 4, Book 5, etc.The owner lost the third book in the middle of writing it, but there is no sign that outright confirms that he died after that. In fact, it's implied that the author(s) is/are still alive. That opens up the possibility of the author writing more volumes after he lost the third book.
The llama symbol in the opening represents Wax Larry King.And all the characters represented by the symbols will somehow play a role in summoning "BILL" (the triangle guy).
Dipper, Mabel, Soos, and Stan are in a different dimension.They traveled to a whole different dimension when they went through the hole in "Bottomless Pit".
It wasn't the summer heat that melted the dinosaur outIf it was, they would all have gone on a rampage during "The Deep End". Clearly something (or maybe someone) else released them.
The golden pendant Stan had in his Self-Serving Memory about the dinosaur has some significance.There was no explanation for it, and it was glowing!
The pyramid guy is summoned when all items in the circle are brought togetherHe can clearly be seen in the trailer for the new episode "Dreamscapers", and this trooper thinks he saw Mabel in the same sweater as in the first ep.
The pyramid guy has something to do with alchemyMy sister came up with this. Alchemy is from ancient Egypt, right? He's a pyramid, which is a triangle, which is the alchemist symbol for fire. (As Dipper pointed out in "Irrational Treasure")
The T. rex and possibly the other dinosaurs trapped in the amber in "The Land Before Swine" will come to life.Obvious Sequel Hook is obvious.
Whatever reason the symbol on Stan's fez has switched from 'crescent moon' to 'Pac-Man' is important.And I'm 100% sure it has something to do with the same moon symbol being on the circle in the opening.
Bill has fourth wall peering powers.According to Bill in Rumble's Revenge, "Your reality is a game to me. And I like games...". And, who am I kidding, I really want to see this show break the fourth wall.
Carla "HotPants" McCorkel is the same Carla referenced in "The Hand that Rocks the Mabel".Not sure whether or not this was inherently obvious, but I figured it constituted a WMG.
Dipper and Mabel's hands will be a plot pointThere is a very weird inconsistency with the number of fingers on the character's hands. It seems like all the adults have five fingers, while all the kids (except Gideon, for some reason) have four fingers. The journal on the two books concerning the phenomenon around Gravity Falls have six fingers on them. Possibly this might be brought up in a future episode of Gravity Falls, and might be a vital plot point.
Wendy's family is ridiculously wealthyBut she hides it because she wants her friends to like her for who she is.
The woodpeckers are not what they seem.They are a form Killer BILL takes.
Leaked Image Person and Stan's twin worked together on a government project to study Gravity Falls.They did it For Science while the government agency that funded them was looking for something supernatural to weaponize. Leaked Image Person was assigned to the project first (or perhaps studying Gravity Falls on his own accord before the project began), and "Grandpa Stan" joined later and was the one making edits to the books. They eventually found something so powerful (the thing in the Shack that Grunkle Stan is hiding and Gideon wants), they decided to hide it from their superiors and the world. They both went insane and paranoid of one another (and even their own family) while hiding it. Grunkle Stan eventually stumbled across it or saw his brother attempting to use it and had no choice but to fight him. "Grandpa Stan" eventually fell down a cliff, uttering ominous words of vengeance as he fell, thus explaining Grunkle Stan's temporary fear of heights and why he was so terrified at Wax Stan at first. The thing he was hiding or one of the experiments he performed with Leaked Image Person has made him superstrong/immortal, so he has indeed survived (or become undead) and will return for revenge. The thing they are hiding is instrumental in bringing about Bill's (the 2D triangle guy) true form (a 3D pyramid) into the mortal realm, and he is just using Gideon as a pawn to obtain it. The floating eyes are all fragments of Bill peaking into their universe.
There will be a Bigger Bad.Near the end of Dreamscapers, Bill warns us and the characters of a mysterious darkness that is approaching and that will change everything. It will probably be a being more dangerous than even Gideon is.
In return for helping Gideon get the deed to the Mystery Shack, Bill was going to ask for Gideon's book.Either for his own purposes, or to deliver it to the previously hinted at Big Bad.
Stan's mind has ciphered words and such because his mind has been ciphered, possibly by Bill Cipher.He actually doesn't remember anything, he isn't faking. His mind has been tampered with.
That golden pendant Stan wears is an amulet from one of the booksAs stated above, it was glowing during his story in "Land Before Swine". Plus, we know that there's at least one other book out there, and both of the ones we've seen so far came with what look like amulets.
The time paradox Dipper & Mabel created when they were messing with the time travel device will come back to bite them somehowI don't know how, but they probably affected history more than we know. And when that creates a problem, Blendin will return and have to help them fix it (and the twins will befriend him in the process) leading to a Some Anvils Need to Be Dropped that TIME TRAVEL IS NOT TO BE PLAYED WITH!!! [[spoiler:Look in the background of the scene where Gideon gets reveled as a fraud in "Gideon Rises". Blendin Blandin is there
Wendy will fight back in the season finale.She'll get her dad to kick Gideon's ass since she hates him as much as Soos and the Pines do.
Gideon's ultimate fate will be an eternity of torture from BillNothing too graphic, but something pretty unpleasant.
Stan knew full well he was under the truth teeth's influenceHe just managed to use Half Truth and You Didn't Ask to keep from giving away any important secrets. The whole thing was to teach Mabel a lesson. (The one she learned at the end)
Soos was expecting to see Jennifer Aniston in Stan's mindI'd say she qualifies as a "hot old lady".
Alex Hirsch reads TV TropesSee the above theory about Gideon being a living puppet? Bill joked about it.
Next episode, we'll FINALLY find out what the hell is behind that vending machineThe Shack was getting destroyed at the end. It's now or never.
Stan's fez used to belong to someone else. Someone important.When Gideon was summoning Bill to go into Stan's mind, he drew an arrow pointing to the glasses, but not the symbol on the fez. Meaning the glasses represent Stan, but the moon/Pac-Man thing is someone else.
Bill is the big good of the serieswith heaping doses of good is not nice, and manipulative bastard. he frequently makes comments about people being useful and one of his last comments before disappearing is to warn them of a great evil coming, also once they best him he comments on them being impressive and useful he may be planing on using them to hold off the great evil, but he thinks in cosmic scales and geological time so a our lives are small and insignificant, his issues with Stan come in that Stan actually values human life will bill views them as a pawns in is cosmic war against evil
The 10-Point Symbology CypherThat wheel of symbols DEFINITELY correlates to specific characters in the show, if not also character traits akin to the Elements. The confirmed ones are listed below, along with gaps for theorists to fill in:
Bill Cipher is Nyarlathotep.
Bill will fight the Time BabyHow epic would that be?
The Quentin Trembley cover-up was a cover-up.Trembley was actually sent to Gravity Falls to research all the supernatural happenings there. He eventually discovered something groundbreaking that couldn't be taken advantage of with the technology of the time. Writing down whatever he discovered risked the possibility of the information falling into enemy hands, so instead he preserved himself to pass on the information to the future. They came up with the president story as a lie to the people sent to retrieve him so that they wouldn't be suspicious of the true nature of their mission.
Bill will turn out to be a morally gray character.Sometimes he does bad things, but he's not completely evil.
The main characters will all take on some kind of magic to fight whatever Big Bad comes along.One character might practice witchcraft, another might opt for becoming a werewolf, etc.
There will be a big return of mythical creatures that appeared in previous episodes.
Behind Stan's vending machine is a room where a great evil is sealed.When Gideon and his father destroy the place, the evil will be unleashed.
The Cipher on the dream-shack will be importantNo, not the one above the door, that just says Mystery Shack in the original Cesarean. If you look at the roof in the same scene, in big letters is "OAUVG" and this troper has run it through both Atbash and Cesarean and come up with bup-kiss, so it must be a cipher not used yet. And if you look carefully at Bill's Bloodstained chapter you'll see what might be conformation to the part about a new cipher, as scrawled at the top, in descending order, is Cesarean, Atbash, and A 1 Z 26, all crossed out.
The books are the records kept by individuals belonging to a secret societyIts been hinted at on this page, but never out right said, so now putting it down. A secret society that Grunkle Stan may or may not be part of (aka he totally is) that is dedicated to at least monitoring, if not out right influencing, for good or for ill, the supernatural element centered in Gravity falls. Membership into the secret society could be passed down through family lines
"Stan is not what he seems" is exactly what it says on the tinMeaning, that the code is supposed to make you suspicious of Stan, when actually, he's not as suspicious as he seems, and really knows nothing.
Behind the vending machine is....The heart of the house. It is a living object by itself, it's personality and knowledge based on what it contains at the time. It will end up defending itself in some way against Gideon and his father, and go back to its dormant state after its settled, like nothing happened.
The books are representative of the three core rulebooks of Dungeons & Dragons.The books have a numerical order that can easily correspond with the books in the series. Dipper's book, the third, is the Monster Manual. Most of the contents we've seen are in some way about magical creatures. Gideon's, number two, is the Dungeon Master's Guide. It contains information on magic items, as well as fitting Gideon's manipulative nature. This leaves book number one, the Player's Handbook. Easily the most powerful of the three, as a large chunk of it is dedicated to describing, in detail, a large number of magic spells, from simple to world-shatteringly powerful. This is why it is the last book to appear in the series, as it will serve as the driving factor of the climax of the series as a whole.
The gnomes are somehow connected to Bill Cipher.Book 3 makes note of their hats' shape and according to the manotaurs they live in the trees. Book 2 makes note of Bill's connection with birch trees.
Old Man Mc Gucket will be extremely important somehow.The leaked image shows a man who looks like a younger version of him writing in one of the books. This suggest that he's a big part. Now, here are a few theories to the character in general...
Stan has had problems with Doppelgangers.In Headhunters, he massively freaks out when he first sees the wax figure of himself. He may have faced some kind of doppelgangers before. Possibly because of the copy machine they have that can clone things.
The Illuminati are a cult that worships Bill CipherHence why the pyramid eye is so prevalent in their symbology
Stan has one of the books.It's what he's hiding behind that vending machine and it's why Gideon wants the Mystery Shack so bad.
The twins will visit the distant future in one episode.They may accidentally meddle with the fates of their future selves.
Bill has been watching the entire time.You can spot images resembling him everywhere, all throughout the series. Since Bill can only manifest in the dreamscape, he uses these little areas as sort of a way to see what's going on at the Shack and other areas of Gravity Falls.
Eventually, we'll have to sort these into foldersJust throwing it out there.
The DVD covers for complete seasons will be designed to look like the journalsWouldn't that be pretty cool?
Theories on what the hell that thing Stan activated at the end of the season is
Old Man Mc Guckethas nothing to do with the books.
The circle with the pictures is magic and changes from time to time.It may change depending on who is reading it, or whoever fits the requirement for getting into the circle. If a person alters their appearance in a way that changes the symbol, the symbol on the circle will also change.
Bill does not have a physical form, and exists only as a mental or symbolic construct.
Playing off the above theory, Bill wanted Gideon's help to manifest himself into a physical form.Once Bill has physical form, he can use all his dream world powers in the real world. Perhaps he wants to cause damage or get revenge on Stan for something. His request to Gideon would've been something extreme, such as wanting to use Gideon's body as his own.
Regarding "Stan is not what he seems".That statement really means "Stan is not just a fraud". It's to tell the reader that Stan does, in fact, know about real magical creatures and oddities, and isn't just about the fake stuff.
"The Blind Eye" is the name of a secret society behind all the mysteries at Gravity FallsIf not the WORLD
The Butternut Squash with a human face and emotions will turn out to be the Bigger BadBecause how could something like that not be super evil and powerful?
Stan will cause the forewarned Apocalypse.Whether or not it'll be on purpose, we have yet to find out.
Blendin Blandin was trying to prevent Stan from getting journal #2(Take a close look when Stan drives up to the crashed robot. He's there.) Whatever that thing Stan activated was, it causes BAD things to happen. Things like what Bill warned us about. Blandin is trying to stop whatever it is from coming to pass.
Old Man McGucket will work for the next season's villain
If Grandma Pines shows up, she'll be voiced by Ariel Hirsch.
Bill Cipher drove the original writer of the book to madness.Assuming the leaked screenshots showing Old Man Mc Gucket as the writer of the books are accurate, and assuming that he was the only one writing the books, Bill Cipher was the one who drove him to madness. The second book talks about how to summon him while the third book talks about how to stop him. What's more, the third book's entry on Bill is initially written on a positive note, talking about how he's such a nice guy. It's all crossed out, and replaced with a warning about how dangerous he is. This might indicate that the writer trusted him for a while but was betrayed and saw his true power.
The red marks on Bill Cipher's page in the third book is really all just red ink.
Soos knows more about the books and/or the strangeness in Gravity Falls that he lets on.The cryptograms in the Rumble's Revenge game foreshadow the appearance of Bill and certain events of the season finale. (such as Gideon looking for the other books) One cryptogram that has yet to come true is "The handyman knows more than you think". Now, Soos seems to view Stan as a father figure and is willing to keep secrets for him. (such as in "Dreamscaperers", when Stan told him why he's so hard on Dipper. Soos never tells Dipper even as Dipper gets more and more upset and even gives up on Stan) It could be that Soos knows about the book, or the secret society that was mentioned in another cryptogram. (one that has also yet to come true)
Members of the Secret Society.With all the WMGs about secret societies, it's about time we try to figure out who the members are.
The goal(s) of the Secret Society.Playing off the above, if the Secret Society exists, why do they exist?
Stan's tattoo is the symbol of the Secret Society.And all the other members have similar ones.
Why Stan wants that huge gateway thing in the finale opened.I believe Stan wants that thing opened so bad because all the mysterious creatures and artifacts in Gravity Falls escaped the portal the first time the three books were brought together, possibly by Stan. Stan wants the portal opened because he wants to send all the mysterious things back.
Stan wants to open a portal to another universe to...
All the strange things in Gravity Falls are there because of the portal. A code in the book does suggest that the large device at the end of the season finale is a portal. The strange things in Gravity Falls are just that: strange. Indicating that they don't appear in many other places on Earth. And all the strange things there came out from the portal while it was open.
Gravity Falls doesn't exist except for five people.Of course Dipper and Mabel don't count, they're outsiders, not true residents of Gravity Falls. So we have four people, The author, Soos, Gideon, Stan, and Wendy. The creatures are real and just game pieces for this fight. Before hand, the author died to Wendy. Why? "Trust No One!" There's no coincidence that Dipper, the brains between the twins got the book. It's the key to ending this power struggle. And who in the entire town would Dipper trust more than the woman he is in love with: Wendy. Wendy is too tall and looks too old to be a 15 year old girl. Lumberjack genes aside, she has men going for her, Robbie and Dipper who are enemies merely because they want the same woman. What creature would have the same thing going? Wendy=Succubus, or as close as Disney would allow a Succubi. Gideon is very reminiscent of another psychic child in a movie, the Twilight Zone where a little boy with psychic powers changed an entire town to everything he wanted and tortured people at will with his reality altering abilities. His favorite target? His parents. Who is suffering the most from Gideon? His mom. Gideon=Reality Warper. Now, good guys, villains need their heroes right? Soos, everyone typically agrees that Soos knows more than he lets on. He helps the kids, actually shows an interest in them beyond the immediate and even guides them at times. It's quite possible that he's ultimately the force that led Dipper to the book. Combined with Bill noting Soos especially in Dreamscaperers, I think I know Soos' position. Soos=Guide Now for Grunkle Stan. He's a creep, a jerk, and a borderline crook right. He's not what he seems. He's in a dream town, surrounded by idiots, why not look hopeless and tricked and have some fun with it? Even heroes need fun. He also helps train Dipper in his own way. Think of it as Disney friendly Training from Hell. Stan=Teacher/Mentor Now for the author. I believe he's a neutral entity that realized that he was dying thanks to a succubus and reality warper and wrote the journals to combat them and with his dying breath gave them some power. Soos is possibly his son. Stan would probably have been a friend with Wendy being a demon they summoned for whatever reason and Gideon joined in later for a power struggle that Dipper and Mabel got stuck in the middle of with Dipper chosen to be a savior type.
The goat rules over everything.
More on the Stan has a twin hypothesis.Check the scene where Stan's father makes him take boxing. Although his face is obscured by the book he's reading, the kid in the top right corner looks identical to Stan.
Bill Cipher can see everything.Anything resembling his image or inscribed with his eye will allow him to see what's going on everywhere. This may include the audience.
There is an Insanity curse on Gravity falls.The rest of the world is normal like ours, but a curse makes everyone in Gravity falls varying levels of crazy. It is possible to be affected by this curse by being born there, living there for a certain amount of time, or being descended from inhabitants. Mabel received the curse, but Dipper didn't, or is only affected by it minutely. The curse stems from Quentin Trembly being frustrated by the rest of America not taking him seriously, so after he founded Gravity falls he summoned Bill Cypher and requested that he make the rest of the world understand him. Bill Cypher agreed, but only the town was affected because it took a while for the curse to spread, and during that time Quentin was sealed in peanut brittle, causing the curse to be contained only to the town.
We will see some kind of mutant monster piñata thing at some point in the future.Maybe Soos knows something about it. He did give Dipper a baseball bat in case he ever saw a piñata, but then again, this could just be Soos being Soos...
Grunkle Stan is a Time Lord.Once the Great Time War ended, he got stuck in a small town in Oregon and has been trying to get back to his home timeline ever since.
The author of the books is Old Man McGuckett.
Multiple books, multiple authorsAs someone else pointed out above, book 2 gives instructions on how to summon Bill Cipher, while book 3 warns against him and tells how to get rid of him. This might suggest to different people writing, one for aiding the demon (Either a result of brain washing by Bill or an honest thirst for power and chaos, that's another WMG) and one against. Maybe the three journals were the journals of three people who discovered the portal, divided the instructions between them to keep its power safe, but then something happened to turn at least one against the others.
The battle between humanity and the Time Baby only happened in timelines where Mabel never got Waddles.The Time Baby's seat of authority may have to do with the timeline being changed back to normal.
Dipper's real name is Darell
Bill Cipher is LuciferBased on a real thing, this troper was watching the show when my Uncle (an ex military codebreaker) walked by stopped and asked "What kind of cartoon has lucifer in it?" Bill Cipher is a coded version of LUCIFER. (Cipher = Cifer). Bill is harder to explain, basically if you but the alphabet in two rows I is across ( / in this direction) from U. Double L means keep it and the B is a fake letter in the name. The "joke" is the meaning of the word Cipher, to decode. Its normally used in reference to a code that makes no sense or ultimately has no answer/is untranslatable. Its also used to confuse the enemy with nonsense terms. Because Lucifer's thing is confusing or out right converting the righteous to evil through lies....
Grunkle Stan's twin brother went through the portal.Either by force or he went in on his own. Grunkle Stan wants to open the portal to get his brother back.
The town of Gravity Falls connects to the world of Chick Tracts, thanks to Bill Cipher.
The title of the show was originally going to be "Twin Pines."
Season 2's first episode will lampshade the long gap between season 1 and 2.
The Christmas special will feature Dipper and Mabel meeting Santa Claus
Bill Cipher has relatives
Gravity Falls was once an SCP Foundation research siteIt was abandoned (likely because one of the SCP's went really wrong) and for some reason or another was completely lost to the Foundation, allowing all the other SCP's it contained to run amuck and make Gravity Falls the weird and wonderful place we know today. Also, the journals are the research notes of the last Researchers from the forgotten site.
Gravity Falls shares exists in The Secret World universeThe coming Darkness will be an outbreak of The Filth in the town, Bill Cipher is actually the Pyramidon of the Illuminati, and the secret society in Gravity Falls is related to one of the three main factions. But which one?
Sheriff Blubs was actually a competent cop before he came to Gravity FallsDeputy Durland is using some kind of device on him that makes him more incompetent. After all Santa personally chose him to investigate the Quentin Trembley conspiracy. Deputy Durland who can't even read is always with him.
The changed fez symbol is significant. It shows Cipher gaining influence over StanThe symbol changed from a crescent to a "pac-man." The outline of the cut and the new circle is the shape of Bill Cipher and his eye. The corresponding crescent symbol in Cipher's circle in the opening credits has also changed to the pac-man symbol in the third book. Cipher made this change to get Stan under his influence, to seek to open the portal for evil purposes. The other portal seeker, Gideon, also has a symbol that is very Bill-like (the eye in the pentagram). Gompers the goat was the agent of the change; the last time we see the old symbol is before the fez falls off and Gompers grabs it in the "sorry dance" at the end of "Boss Mabel." This means that Gompers works for Bill. Gompers also chewed the "Shooting Star" sweater of Mabel's, which is the symbol by which Bill addresses her. (In the episode before "Boss Mabel" we can see the beginning of the change on the face of the "Stan Bucks", which has the "pac-man" without the ball.)
Bill is having more trouble influencing Mabel than the othersThe omelet Mabel made for Stan in "Carpet Diem" is significant because it had the old fez symbol. Stan ate it with extreme enjoyment because it made him feel like his old self. This may have been a setback for Bill. The fact that Mabel can still remember the old symbol and use it reflects that she is less under the influence of Bill than the others. Her changing wardrobe of sweaters may protect her. Bill seems to have dedicated a second symbol slot to her (the llama) to keep up the pressure.
The Blindeye is Bill's blind cousin who owes Bill 20 dollars and something that works for PIIIIIIIIIIIIIGS!Brought to you by Homework: The Candy.
Grunkle Stan betrayed his brother Stanley. Going off the theory that Grunkle Stan(ford) has a twin brother named Stanley who wrote the books, I propose that Stanford seriously betrayed Stanley at some point, hence the writing in the book that you can't trust anybody. Stanford is trying to build and activate the machine to in some ways make amends.
the author of the books is bigfoot.
Theory on Grunkle Stan's ex-wifeIf the Grunkle Stan has a twin theory is true, then I propose this other theory to go along with it. After Grunkle Stan's twin disappeared, Grunkle Stan's ex-wife had a hunch that her husband knew what really happened to his brother. She pushed him for answers, but he flat out refused to tell her anything either out of guilt and/or fear. Believing that her husband didn't trust her, she called for a divorce which Grunkle Stan was more to happy to oblige by. After that, she moved out of Gravity Falls and refused to ever return. But, considering the rumor that Grunkle Stan's ex-wife is said to appear on the show...
The "Hide Behind" is a HeartlessIt's all Black, except for it's eyes, which are yellow. Sounds like a pure heartless. And disney owns everything from Kindom Hearts other than Pre Existing Square Enix characters, so they could add a Heartless to one of their other properties with no issues. alternitivly, Gravity Falls might be a world in KHIII, with the Hide Behind as a Bonus Boss
Mabel has a doppelganger named Lebam. She has appeared in several episodes in Mabel's place.When Gideon first asked Mabel to visit for a makeover, he was preparing a spell from book 2 to make a doppelganger of her, possibly as a backup girlfriend. He took a sample of her hair and (possibly by accident) her llama-hair sweater. After she went home he completed the spell and Lebam was born. He took her around town in a plain sweater and got a photograph in the newspaper, and got a fan magazine quickly printed up featuring their relationship. Later she left her plain sweater in the warehouse (it can be seen draped over a table when Dipper enters). She eventually went to Mabel, who agreed to hide her and let her share her family life, wearing duplicate sweaters so they could switch back and forth. Credit for finding all these clues goes to "The Sqoou," who posted them on You Tube. To see how all this might work together as a story, see "The Life of Lebam" on fanfiction.net.
Wendy is secretly a yuki-onna or a water demonWendy is theorized to be what the bag of ice that on the cipher wheel represents. This is assumed because she is frequently near ice (The water cooler on the roof, the ice freezer at the convenience store, the snow cone at the fair, eating ice cream with deeper) she is supposed to be "cool" (she is often never fazed by anthing and Dipper and Mabel look up to her) That and combined with as of now (end of season 1) we don't know much about her history, some assume that she might have some kind of paranormal relation to water, ice or cold.
Stan is a member of a secret society that is somehow involved in the Gravity Falls conspiracy, his fez indicates his membership, his change of fez inbetween episodes 13 and 14 is representative of a change of rank in that society
Dipper is related to Ned Flanders"How are you diddly-doing, Soos?"
Bill Cipher is a robot constructed by the Time Baby organizationThe two main interfering entities in Gravity Falls are connected. Bill is a construct of the time travelers, only posing as an all-knowing demon. He works for the Time Baby. His bow-tie is his equipment logo, the triangular infinity symbol of the Baby. The time slow-downs and reversals around his summoning in "Dreamscaperers" look a lot like the first operation of the tape-measure time machine in "The Time Traveler's Pig." One of the things Bill revealed in "Dreamscaperers" as one of the "lots of things" that he knew about was the crashed Gideon-bot. Blendin was there and could have taken the picture that Bill displayed.
Dipper is Domiclese the shepherd robot, displaced in timeDipper shot lasers from his eyes in the dreamscape, and he's associated with lambs. Perhaps he is actually the robot shepherd Domiclese from ancient Greece (from "Mabel's Guide to Stickers"). Mabel may be a robot as well. This modification may have been protected, so new mind-wipes won't take. (Robot may be the wrong word. Dipper needs to be human enough for a mind-swap to work, so call him an android. But he's tougher than an ordinary human. He survived a super combo punch from an entity that can destroy a car with regular punches.) To see how all this might work together as a story, see "The Life of Domiclese" on fanfiction.net.
An Axolotl will appear at some point in the series, and it will either be benevolent creature to the Mystery Shack or a helper of Bill Cipher.I don't have any proof so this might be ignored, but I got an idea from reading-not seeing-that axolotl's pictures are used whenever a spoilery question is asked. Maybe the Axolotl, if it does appear, is benevolent and is on par with Bill Cipher on intelligence, which means he knows everything too, and wants to help Gravity Falls survive the Darkness that approaches. If it's malevolent though, then it will be a minion or possible messenger from Bill Cipher, whose appearence shall be the first clue that whatever Darkness Bill was talking about is about to arrive.
There is a lizard monster coming up in a winter-like episodeA new short from Italy shows a couple of snapshots of a new monster in Mabel's album. He looks like a human-sized lizard and wears clothes like those in a Dickens novel, with a top hat and a monocle. The background shows snow. Mabel will win a dogsled race against him. (The short is called "Visiting the Petting Zoo.")
Soos' name will be significant because it's a palindrome.Considering how important the idea of backwards messages and mirror images are in this show, Soos' name being the same backwards and forwards will make him immune to something. Especially if that something is a power of Bill Cipher's: he only seems to know individuals by their sigil on the wheel until he hears someone else say their name, and no one ever calls Soos by his full first name.
Bill Cipher can influence people through gold. Stan knows there's a connection, but not what it is.Old Man Mc Gucket has a gold tooth. What if gold acts as a sort of conductor for Bill's powers, and that's how he drove the poor guy insane? Stan asks about whether other people are buying gold and is apparently invested in having some himself, but he has no known reason to want to increase Bill's influence over anyone; he may think that gold and\or money acts as a ward against Bill, which is why he's so hell-bent on profits and ripping people off.
The "blindeye" is a ritual to stop Bill's omniscience.It's done by defacing currency, specifically putting an X mark across the Eye of Providence on the dollar bill. Bill is, literally, the almighty dollar! That's why Bill has to be reminded of Stan when he seems perfectly aware of everyone else: Grunkle Stan has more money pass through his hands than almost anyone else in Gravity Falls, and he's extremely reluctant to spend it in Gravity Falls. He has Soos mark out the Eye and then spends as much as possible on things not within the town in order to keep anyone from catching on!
Gravity Falls is an artificial Eldritch Location created by a men-in-black like organization for dumping dangerous items.The series already has established time police characters, and one can often be seen somewhere. It has been established that those characters are trying to maintain their time-line. The kind of secrecy required for that kind of goal would necessitate a men-in-black like organization. The organization probably encounters loads of random unstable junk that could be a threat. It's practically a rule. So they created a location to dump certain things that could be a threat, in the manner of Warehouse 13. The town is a secret place created by a secret organization to get rid of stuff that can't be destroyed and is extremely dangerous. That explains why the town is so weird. The odds are that someone probably noticed all the bizarre items, and started cataloging them, in the style that this wiki does. The secret organization found out about him, and eliminated him. That's why book 3 stops in the middle. He knew he was being followed, and hid the books so they couldn't be destroyed.
Mermando will returnAlong with his family. The episode will dive deeper into the Mermando x Mabel relationship. It will involve a parody of The Little Mermaid in which Mermando magically develops legs to get closer to Mabel.
The Northwest family knows about Gravity Falls' secrets.We know virtually nothing about Pacifica's mom or dad, other than the fact that she was related to Nathaniel Northwest (who didn't even found the town). Plus, Alex Hirsch has said that Pacifica will get more development in S2. Maybe this ties into it.
