** Mabel is excited to go to high school next year, and confides in Dipper that they'll be taught about "''You know''..." Dipper eagerly replies "Trigonometry?" It turns out that [[StrangeMindsThinkAlike was indeed what Mabel meant.]]

* FriendOrIdolDecision: Ford offers Dipper an apprenticeship in Gravity Falls, which means Dipper wouldn't be returning home to Piedmont with Mabel. Dipper decides to accept the apprenticeship, which Mabel learns via the walkie talkie Dipper left at the Mystery Shack, to her chagrin.

The end of August is approaching, and so is Dipper and Mabel's 13th birthday. Mabel is eager to begin party preparations, but Stan refuses to hold the party at the Shack, as the last one ended in a ZombieApocalypse. Soos suggests that they see if they can use the high school gym, but before the Shack crew can leave, Ford calls for Dipper; the Rift's container is starting to break! If the Rift becomes exposed, Bill Cipher will be able to merge his dimension with Earth's creating a disaster called "Weirdmageddon". However, Ford has also found an answer to the problem. It's a super-powerful extraterrestrial space-adhesive strong enough to seal up the Rift for good. Ford asks Dipper if he would like to come along, and while Dipper is ecstatic to go on an adventure with the Author, he also doesn't want to leave Mabel behind. Mabel, however, tells Dipper to go on whatever important mission Ford needs, and that they'll stay in contact with walkie-talkies.

Out in the woods away from the Shack, Mabel is approached by none other than Blendin Blandin. Blendin claims to have overheard her woes, and offers a solution; To freeze Gravity Falls in a "Time Bubble" that will keep summer there from ever ending. All he needs is some weird thing her brother has…the cracking Rift. Mabel, tempted by the opportunity for "Just a little more summer" gives the Rift to Blendin- who shatters it! Laughing maniacally, Blendin takes off his goggles to show that he has Bill Cipher's eyes! With a snap of his fingers, Bill knocks Mabel out and leaves Blendin's body. He then tears open a hole in the sky, ecstatic that the day he's waited for has finally arrived.

* AesopAmnesia: All of the Aesops Mabel should have learned are being ignored here; not much "If I love them, I should let them go" (from "Boyz Crazy"), "I can't expect my brother to give up everything for my sake" (from "Sock Opera") or even "Using strange weird things to interfere with people's lives is wrong" (from "The Love God"). Her emotional state is in the gutter after having everything she thought she could count on (TV's depiction of high school, and Stan's assurance that Dipper will always be there) shot down in the space of a day. She only hesitates a second before giving up the weird thing in her brother's backpack if it means not facing the future and inadvertently allows Bill Cipher to bring about a WorldGoneMad.

* AncientAstronauts: A spaceship crashed on the present site of Gravity Falls millions of years ago. Ford speculates whether the crash caused the anomalies in the area or it was the anomalies that caused the crash.

* BreakTheCutie: This episode is just one broken dream after another for Mabel. High school turns out to be much less glamorous than she thought, her friends won't be able to attend her party, and Dipper is planning to become Ford's apprentice, so she won't even have Dipper to rely on when summer ends. Mabel is left emotionally vulnerable to the manipulations of Bill Cipher.

** Ford read the new stuff Dipper has been adding to Journal #3, like the Gnomes' weakness being "leaf blowers" all the way back in the first episode.

** Bill is possessing Blendin Blandin, who was seen as one of his possible suggestions outside the Mystery Shack during TheStinger of "The Last Mabelcorn".

* DownerEnding: Mabel and Dipper end up in an argument that ends with her running off into the woods crying, unwittingly taking the rift with her. But that's not the REAL bad part. Blendin Blandin shows up offering to help her have an eternal summer in exchange for the rift. She obliges... only for him to smash it open, laugh maniacally and remove his goggles... REVEALING BILL CIPHER'S GOLDEN EYES BEFORE HE KNOCKS HER OUT. He then pops out of Blendin, rises up and projects the rift into the sky, laughing maniacally while Ford and Dipper can only watch in horror as Weirdmageddon begins.

** Dipper can't take Mabel seriously when she yells "the future!" because of the face on the chin.
** Dipper tries to run dramatically joining Ford but hits the wall, then trips on the way out.

* TheHerosBirthday: Dipper and Mabel's 13th is approaching. Notably, this marks not only the end of their childhood, but also the end of the summer and their time at the Mystery Shack. Of course, if Dipper follows through on his deal with Ford, he'll be staying for a long time... y'know, provided they both survive the incoming apocalypse.

** Once again the fate of the world lies in Mabel's hands, and she goes with her heart rather than with her mind. This time though, it comes back to bite her in a world-ending way.

** Dipper and Ford keeping the rift a secret from Mabel leads to her giving it to Bill without her knowing what it is.

** The last scene before the credits is Bill turning Earth [[HellOnEarth into a nightmare]]. The credits clip is just a shot of a crumpled up invite to the party as the screams and lamentations of the entire town can be heard in the background, alongside various explosions and a helicopter flying past.

* PassingTheTorch: Invoked by Ford; he's aware that he's getting old, and Gravity Falls will need someone to keep track of its weirdness. He offers Dipper a chance to be that someone, citing Dipper's past experience makes him the prime candidate.

* ShaggyDogStory: Ford and Dipper's quest to find adhesive for the rift. After nearly getting launched into outerspace and facing killer droids, not to mention getting a few head injuries, they lose the rift thanks to a misplaced backpack, an informational lock-out and Mabel's emotional breakdown.

* UngratefulBastard: Mabel and her friends fought and obtained unicorn hair to protect the Shack, something even Ford couldn't do, but this episode shows that he still doesn't understand how Dipper could possibly need her. In large part this is him [[GenerationXerox projecting his and Stan's relationship onto Dipper and Mabel]], where Stan's attempts to keep Ford at his side probably felt restrictive due to everyone in Ford's life emphasizing how Ford was responsible for the family's future and Stan was just "riding on [his] brother's coattails."

* WhamEpisode: In the one of the most shocking twists yet; Bill achieves his goal of unleashing the dimensional rift, opening a hole in the sky that will end the world. And how does he achieve it? Through ''Mabel''.

** Blendin removes his goggles, showing his possession by Bill.

* YouAreTooLate: This what Ford says when he and Dipper see that Bill has opened the gate to his world.

* AesopAmnesia: All of the Aesops Mabel should have learned are being ignored here; not much "If I love them, I should let them go" (from "Boyz Crazy"), "I can't expect my brother to give up everything for my sake" (from "Sock Opera") or even "Using strange weird things to interfere with people's lives is wrong" (from "Love God"). Her emotional state is in the gutter after having everything she thought she could count on (TV's depiction of high school, and Stan's assurance that Dipper will always be there) shot down in the space of a day. She only hesitates a second before giving up the weird thing in her brother's backpack if it means not facing the future and inadvertently allows Bill Cipher to bring about a WorldGoneMad.

* TheBadGuyWins: The episode ends with with the Rift being broken and Bill starting Weirdmaggedon. The credits scene showcases the terrified screams of citizens while Bill laughs maniacally.

** Grunkle Stan refuses to host Dipper and Mabel's birthday party after "that zombie incident" in "Scaryoke".

* CrossReferencedTitles: With "[[Recap/GravityFallsS1E6DipperVsManliness Dipper Vs Manliness]]".

* DownerEnding: Mabel and Dipper end up in an argument that ends with her running off into the woods crying, unwittingly taking the Rift with her. But that's not the REAL bad part. Blendin Blandin shows up offering to help her have an eternal summer in exchange for the Rift. She obliges... only for him to smash it open, laugh maniacally and remove his goggles... REVEALING BILL CIPHER'S GOLDEN EYES BEFORE HE KNOCKS HER OUT. He then pops out of Blendin, rises up and projects the rift into the sky, laughing maniacally while Ford and Dipper can only watch in horror as Weirdmaggeddon begins.

** The alien ship is full of writing on the walls in Bill Cipher's secret code from ''Dipper and Mabel's Guide to Mystery and Nonstop Fun'', including "[[https://en.wikipedia.org/wiki/Barney_and_Betty_Hill BETTY AND BARNEY]] WERE HERE" and, more chillingly, a message [[CouldntFindAPen written in blood]] that seems to be a reference to the Shape-Shifter from [[Recap/GravityFallsS2E2IntoTheBunker "Into the Bunker"]] ("SPECIMEN HAS ESCAPED IS CHANGING FORM").

* FromBadToWorse: This episode marks this in both the series and the episode itself. While Dipper has what he considers the best day in a long time, Mabel has her worst; her naive ideal of high school is destroyed and her friends can't come to her birthday party. She's inconsolable until Stan tries to cheer her up by reminding her that she'll always have her brother -- right before Mabel hears that Dipper's agreed to become Ford's apprentice and stay in Gravity Falls after the summer is over. When Dipper comes in, happy and oblivious to Mabel's despair, she starts crying at the thought of him taking Ford's offer without her permission, and then runs out after becoming more upset when he tries to explain, because his reasons all have to due with what upset her in the first place -- summer's ending, the future is coming, and Dipper's got to decide his life for himself. Mabel becomes so upset she retreats to Sweater Town, wishing that summer would never end, until Blendin Blandin finds her, offering to grant her wish by [[TimeStop freezing time for all of Gravity Falls forever]]. Too emotional to notice the warning signs, Mabel follows his instructions to search her brother's bag for the Rift -- which Blendin, revealed to be possessed by Bill, smashes to pieces. He puts Mabel to sleep and starts the apocalypse, and the episode ends with the terrified screams of the unseen Gravity Falls townsfolk.

* HoistByHisOwnPetard: Ford not realizing how much Dipper leaving would hurt Mabel when offering Dipper the apprenticeship leads to Mabel unknowingly giving the rift to Bill. Dipper's love for Ford and his exploits into the paranormal also contributes to Mabel's departure. Mabel's paranoia about the future and growing awareness of the problems in her relationship with Dipper (which, despite being briefly brought up in nearly every episode since "A Tale of Two Stans," is a topic Mabel has avoided) contributes to her HeroicBSOD during the episode and her unwillingness to talk it out with Dipper towards the end. Her following drastic attempt to avoid the problem by force everyone she knows to stay the same forever causes the Apocalypse.

* KnightOfCerebus: Bill. When he takes off Blendin's Goggles to reveal his eyes, it is ''terrifying''.

* MenstrualMenace: Wendy implicitly refers to this when listing off the awful things about entering adulthood at the High School.

* PlotMandatedFriendshipFailure: Mabel having all of her unrealistic expectations of the future shot down in one day, plus her paranoia over Dipper leaving her and her fear of growing up, plus Dipper's lack of knowledge of this fear due to him being distracted by Ford and the possible end of the world, ''plus'' Dipper getting the opportunity of his dreams requiring him to live separately from Mabel, equals one damaged relationship, two broken hearts, one horrifying attempt at freezing Gravity Falls so everything is the same a little longer, [[ApocalypseHow and one broken Rift]].

** Because Mabel wasn't informed about the dangers Ford and Dipper were dealing with, she used [[SealedEvilInACan the Rift]] as a bargaining chip in a deal with Bill-possessed Blendin, never realizing what a horrible mistake this was until Blendin took off his goggles.

* ShooOutTheClowns: Soos disappears after the second act of the episode, which makes way for the dramatic part of the third act.

** Mabel became so frightened by the idea of growing up and being separated from her brother that she gave [[CosmicKeystone the Rift]] her brother and uncle tried so hard to protect over to Blendin Blandin, who promised he would use it to freeze time for her so she and the rest of Gravity Falls would never change. Instead, Blendin revealed himself to be possessed by Bill, who promptly broke it and began the apocalypse.

* OneWingedAngel: Cipher is finally free from dimensions to take over that Earth.

** Mabel asks what about the old Disney Channel adage of following your dreams. Particularly about a [[Film/HighSchoolMusical certain musical set in High School]]. Wendy retorts with:

* TeensAreMonsters: When Wendy is telling Mabel why High School is terrible, the thing even worse than super hard classes or your body turning against you is that everyone hates you.

* ContrivedCoincidence: Mabel visits the school gym just as Wendy feels like ranting about how awful the future is. The non-functioning walkie-talkie suddenly starts working just in time for Mabel to hear Dipper's acceptance of Ford's offer. Really, everywhere she goes during the episode, someone's implying or directly stating how unhappy Mabel's future will be.
** Also, the way Bill gets to open the portal to his dimension depends on pure chance, as it wouldn't have worked if Dipper hadn't fixed the orb as soon as he could, if Mabel hadn't accidentally picked up Dipper's backpack, and if Mabel hadn't been kept in the dark about what the orb is.

** Dipper has it when he realizes Mabel took the wrong backpack

* WhamShot: Blendin removes his goggles, showing his possession by Bill.

* BadassFingersnap: Bill knocks Mabel out just by snapping his fingers, which shows how powerful he is now that the Earth and and the Nightmare Realm are merged.

* TheFourthWallWillNotForgetYou: After Bill succeeds in destroying and freeing the rift, we get an extreme close-up of his eye front and center as he rambles, almost as if he's staring at the audience.
