* From a neutral perspective, Annabeth's running away when she was seven makes sense. Children's minds are programed for black and white thinking, so if she got into trouble a lot, it would make sense that she would come to the conclusion that her father and stepmother didn't love or want her. Adding to that, it would make sense as well that Annabeth's choice would be foolish; there's a big difference between intelligence and wisdom. Intelligence is determine by genetics, but wisdom almost always comes from experience, which a seven-year old girl fresh from a comfortable home wouldn't have yet, regardless of having a divine parent or not.
* Athena's apparent dislike of Percy might be only partly because he is Posiden's son. Aside from the fact that Percy has been known to act recklessly, the boy has a powerful scent as a child of the Big Three, and is effectively a monster-magnet. Keeping that in mind, it's understandable that Athena doesn't like him hanging around her favorite daughter so much; she only wants to protect Annabeth. It could also be due to Athena being the goddess of battle strategy, she tends to see people, especially mortals as pieces on a chessboard. It's not that Athena doesn't like Percy (in the past she has help out numerous children of Posiedon before such as Bellerophon, and Theseus was even a king of her patron city), it's that she doesn't trust him.
* We're told that Sally Jackson chose the name "Perseus" for Percy because he, pretty much alone of the great Greek heroes, got a reasonably happy ending. However, Perseus [[spoiler: killed his grandfather (by accident); Percy, by comparison, is responsible for the defeat of Kronos, who is ''his'' grandfather]]. So it's only fitting that history repeated itself.
* An earlier example from the first book: Perseus in Greek mythology killed Medusa on the orders of Polydectes, a king. Polydectes was interested in Perseus' mother and wanted him out of the way so that he could force her to marry him. Perseus returned with Medusa's head and turned him to stone. Percy's abusive stepdad Gabe befalls the same fate.
** [[spoiler: Annabeth's TakingTheBullet in TLO. She was attacked by Ethan, a son of Nemesis, the spirit of retribution against hubris, something that Annabeth admits to.]]
** [[spoiler:If you look at it that way, Ethan and Nemesis even joining Kronos' side. Hubris is considered to be Zeus's flaw, after all. Then Ethan balances this out--while his mother still fights for the Titans, he turns and fights for the gods, against Kronos, who's ego is big enough to have its own gravity field. Really, for all the myths that were messed up in the books, Riordan was ''perfect'' with some of this stuff.]]
* In Book 4, Chiron makes a big deal about how only [[RuleOfThree three]] people can go on a quest. However, by the end there are six, and none of them die. At first, I thought this was a PlotHole or something. Then I realized: six is a multiple of three! Meaning the rule wasn't violated at all through their new knowledge of [[LoopholeAbuse a certain bureaucratic loophole]]. Makes one wonder why they don't just send nine kids(3x3). Or twenty-seven(3^3).
** Because having a bunch of demigods in a single place would collectively create a smell based neon sign declaring "Come eat me" to every monster in a ten mile radius.
** Well, the original quest is actually only 4 people, they need new people to advance the plot.
** But after they first came back, three of them didn't return. Percy was on Calypso's island and Tyson and Grover were still somewhere in the labyrinth.
* Notice that Hades was absent from the winter solstice meeting in ''The Titan's Curse''? He didn't want to draw attention to himself with Nico out there.
** This troper always thought that Hades was there all along, invisible. However, your theory still holds weight, since he's not drawing attention to himself.
* Surely you'd assume that demigod children would know about their divine origins - actually; a lot of gods probably try to keep this hush hush because when some people know it's not turned out well - I mean, Tantalus, a favored child of Zeus, probably left a ''bad'' taste in a lot of mouths in Olympus (Especially Demeter), Phaeton was allowed to drive the sun because his fellow kids didn't believe him, etc. Not to mention when ''mortals'' know that they were in love with a god, not all of them turned out that well. ([[spoiler: It's mentioned in "The Lost Hero" that Thalia and Jason's mom was...kinda screwed up in the head and Zeus didn't really help her that much, until he came around in his Roman aspect.]] [[spoiler: In regards to Piper's dad, this is outright confirmed. Knowing the gods existed [[TheseAreThingsManWasNotMeantToKnow seriously messed with his head]].]]) Plus in today's society being a demigod is a burden than a blessing, as oppose to ancient times, where demigods are practically (and some cases are) worshiped, nowadays being told your a demigod will only make you die faster. Naturally the kids have a right to know are told when they're old enough to handle it; and some mortals who do know about it are told because they can maturely handle it.
* Thalia's last name is Grace. This seems innocuous at first, but I did some digging. Turns out there is another daughter of Zeus, also named Thalia, who is one of the Graces.
** Goes farther than that. Thaleia, the muse of comic theatre, also a daughter of Zeus is sometimes translated as blooming and usually spelled in English as Thalia.
* In the fourth book, Calypso says that she has always sent someone who can't stay, but in the original myth, Odysseus leaves because he is in love with someone else. Meanwhile, Percy is worrying about Annabeth...
* It makes sense for Annabeth and her dad to live in such a high-military area as Jamestown, Virginia, with many universities nearby, since he is a professor of military history. And a lot of the Revolutionary War and Civil War happened in the area. Why he should move out to San Francisco makes no sense, but the Presidio there is also a former military installation.
** Annabeth states he moved to San Francisco because he got a research job there.
* Prometheus was right about the Battle of Manhattan being a reenactment of the Trojan War. However, [[spoiler:he was wrong about which side was which]]. That's because Prometheus is the god of ''forethought'' not ''foresight''. He can predict the future, but as anyone from Greek mythology tell you, the future is not always what you think it is.
* Chiron is seriously dedicated about winning the Titan War because if they lose, civilization falls and then heroes may stop rising. So he is no longer needed. May make Greek History lessons a tad more essential.
* Zoë Nightshade's name becomes this upon reflection:
** "Zoe" means "life"--both appropriate given her longevity, and painful given her ironic demise.
** The nightshade flower is breathtakingly beautiful--and nightshade is a deadly poison. Beautiful and deadly--coincidence? I think not. Also, the flower is deep purple except for the very center, which is bright yellow. In other words, it has a dark exterior but a heart of gold.
** In addition, Zoë was once a Hesperid, a nymph of the sunset. Sunset = shadow of night = Nightshade.
* Percy. Perseus. Annabeth. Athena.
* A chance comment by my niece while we were watching the movie of ''[[Literature/PercyJacksonAndTheOlympians Percy Jackson & the Olympians: The Lightning Thief]]'' made this one occur to me, but I doubt it doesn't apply here, too. Hermes' son is Luke. One of the items Luke provides/uses are winged shoes. This basically means Luke is flying because of his feet. The chance comment my niece made: She called him "[[StarWars Luke Skywalker]]." -- {{Sgamer82}}
* We're told in ''The Last Olympian'' that Nico and the Pegasi dislike each other. This mostly seems to be because his father is [[spoiler: Hades and children of him are generally outcasts]], but in ''The Sea of Monsters'', Percy mentions that Pegasi are sort of neutral territory between Poseidon and Zeus only. [[spoiler: So naturally the Pegasi would dislike a son of Hades!]]
* I was always a little confused about how [[spoiler: Silena Beauregard got the Ares cabin to believe she was Clarisse and follow her into battle, because she and Clarisse don't look anything like each other. But then in ''The Lost Hero'', it's revealed children of Aphrodite sometimes have the ability to make other people do stuff with their voice. No wonder they believed Silena was Clarisse, she ''charmspoke'' them into it!]]
** It's never stated that [[spoiler: Silena could charmspeak]], but it's a possibility.
*** I think it's more likely that the entire cabin wanted to go to the fight (because it was the right thing to do) and took any excuse they could get.
** The above is pretty much explicitly stated, but it's also a pretty obvious allusion to The Iliad (the need-to-know book for info on the Mist). Achilles (Clarisse) was the best fighter and led the finest men in the Greek army, but (s)he sulked due to having a prize earned in battle awarded to someone else. (Thankfully, Clarisse's prize was a flying chariot, not a slave girl.) At the battle's most desperate point, Patroclus/Silena took Achilles' armor and led his men into battle to hearten the Greeks. Achilles' men knew it's not really their leader, but they want to help the Greeks and will follow ''anyone'' at that point.
* Something this troper realized after reading the Great Prophecy a few times: Hades got his wish! All three children of the Big Three were the child mentioned in the prophecy! Just hear me out for a moment: Thalia skips out a few days before her age-16-birthday, but she had already been around for at least 16 years before that and did that against all odds (she got turned into a tree after she died). Her choice to 'pass' allowed Percy to be the child. Same for Nico: he too survived against all odds (getting a lightning-bolt thrown at the place you're in is usually deadly) and his choice to allow Percy to 'be' the one gave Percy the chance for HIS choice to give Luke the knife to save Olympus. Ergo: if either Thalia or Nico had chosen differently, Percy would not have gotten his choice and Olympus might have fallen!
** Not how prophecies work. The Great Prophecy always referred to Percy, it's just that Thalia could have theoretically been the demigod it spoke of, and Nico (or Bianca, for that matter) could have as well if Percy had been taken out of commission. They didn't know for certain which one it referred to, hence the confusion and manipulation, but it was always going to be Percy.
** Also, Nico is younger than Percy. Nico was 10 when introduced, meaning he is about 13 during the Mark of Athena.
* After reading through Battle of the Labyrinth, it struck me that one chapter is titled "We Meet the Two-faced God". Well, yeah, of course, it makes sense in this book that it's got such a weird title, so I was expecting them to literally meet a two-faced god. And of course they did -- Janus. But who else did they meet in that chapter? Hera. I recall how nice she was to Percy and the others. I also recall a story in which it's said she threw Hephaestus off a cliff... Odd for the goddess of marriage and family...
** In the same book, it is pretty much stated that she is almost obsessively devoted to the ideal of a PERFECT family, and, as Hephaestus bitterly remarks, he doesn't quite fit in that with his looks... Not that Zeus' chronic infidelity helps anything.
* Rachel, a mortal who had no ties to the gods until [[spoiler: she became the oracle]], has a very much Jewish name.
** This Troper just reread the story of Rachel and Jacob; when she was having problems getting pregnant she used the magic of the Greeks to conceive Joseph and Benjamin.
* For quite some time, I was wondering what Blackbeard was doing on Circe's island. After all, he was killed by the Royal Navy. Then I realized: it fits. Blackbeard is the son of Ares. Eurytion is another of Ares' children. Eurytion made a deal with his father to come back to life each time he died, making him functionally immortal. Moreover, contemporary accounts of Blackbeard's death describe his headless corpse swimming around the ''Queen Anne's Revenge'' three times. Take all this into account, and it's obvious: Blackbeard made a deal with his father to be effectively immortal.
* If the Oracle hadn't made the prophecy that is the driving force behind the series, then Zeus wouldn't have made the law that him and his brothers should have no more children. If Zeus hadn't made that law, then he wouldn't have tried to kill Bianca and Nico. If Zeus hadn't made that attack, then Hades wouldn't have cursed the Oracle which means Luke's mum wouldn't have gone insane which means Luke wouldn't be the person that he was. The fact that the prophecy was made is what made sure that all the pieces were in place ready for Percy 70 years later.
** Hence the saying; Those who try to change fate, dooms to fulfill it. In this instance, Zeus tried to stop the prophecy, by killing any children of the Big Three and stopping more to be born. The events sparked by his actions lead to the prophecy actually coming true.
* Rachel Elizabeth Dare's initials spell out RED--and incidentally, her red hair is definitely one of her defining characteristics. (Also take into account the fact that her middle name is explicitly mentioned--often--whereas other characters' aren't)
* Pollux and [[DeathByIrony Castor]]. Guess which one of the twins dies while the other one lives.
* The reason why gods do not care about incest? The thing about the gods are that they are physically perfect, part of what makes them godly is that they don't have any flaws in their body(except for Hephaestus). So, the practical reasons behind the taboo on relatives marrying when it comes to people related through gods is void, and assuming they aren't related through their mortal parent, two demigods are as likely to have a child with a genetic disorder as two completely unrelated individuals.
* At the end of TLO, Annabeth takes Nico aside and says something to him that makes him agree to go back to camp with them. However, he acts really embarrassed after having the talk with her. But in House of Hades, we find out [[spoiler: Nico has a crush for Percy]]. Annabeth, being the daughter of wisdom, must have figured it out and used it to blackmail him! This explains why she didn't want Percy to hear them talking and also why Nico was so flustered afterwards!
** Jossed-Annabeth mentions in Heroes of Olympus that she suspects Nico has a crush on her, not Percy. It's more likely that she talked to Nico about that, and that's why Nico was embarrassed. Also explains why Nico plays up the rumor that he has a crush on Annabeth
** I always figured she mentioned how Percy had been looking for him, and maybe some of the things he said at the end of Titan's Curse.
* In TLO, Silena reveals that her father owns a chocolate store, which is how he caught the attention of Aphrodite. This pair seems a bit odd, but consider the role chocolate has in Valentine's Day, which is a day of love, and how love is what Aphrodite represents. The whole situation makes more sense now, doesn't it?
** [[Film/TheRoom They say chocolate is...the symbol of Love.]]
* There's much saying about Riordan "getting myths wrong". However, one thing about myths is that there isn't an actual "canonical" version, they have multiple ones that can say far different things (Uranus would be an example: the most common version has him just eraviated, but in some stories he was actually killed, as it's stated in the series). Most often Riordan isn't wrong, just following lesser known versions.
** Spelled outright in ''Percy Jackson's Greek Gods'': "Now there might be some of you reading this who will be all like, 'But Percy this is wrong this is not the way I heard it so you must have made a mistake!' To those of you like that, all myths had several versions, I'm just telling the ones that I heard and what make the most sense to me, so deal with it."
* [[spoiler: Kronos]] seems far too easy to defeat, in the end, however the sequel reveals that [[spoiler: the giants starts awakening after he is defeated.]] ''The House of Hades'' also reveals that [[spoiler: Gea's favourite children are the giants, and she was planning on their victory all along.]] Of course he was easily defeated, [[spoiler: he was victim of a BiggerBad's schemings.]]
** It's also revealed that the Titans are no where near their full power at all in the series. Kronos was trying to reborn himself using Luke's body like an egg. If he was full power, Percy and all the other demigods would literally be incinerated just from his mere presence.
* After rereading the battle of the labyrinth I realized that Riordan was setting up the groundwork for the [[spoiler: revelation of a roman camp]] in the lost hero and Chiron's knowledge of it early. When Quintus [[spoiler: actually Daedalus]] appears Percy is skeptical of a grown up demigod who had never been to camp halfblood. But Chiron seems to feel uneasy but accepting.[[spoiler: He probably assumed that Quintus was a roman demigod doing what Nico was doing in the Son of Neptune]] this is further supported by the fact that [[spoiler: Quintus was a common Roman name]].
* In ''The Sea of Monsters'', Clarisse is traveling with a Confederation battleship. She states Ares gets the ''losing'' side's equipment and dead men after a battle or war as the reason for this. Why the losing side if he's a god of war? For one, the losing side is less likely to get a proper burial, meaning they would be forbidden from entering the Underworld and their spirits would be forced to wander as ghosts, so he's just putting them to use. Two, since the losing side's dead bodies are more likely to be left on the battlefield to rot, Ares' sacred beards, the vultures, and crows/ravens, would find them quick and eat them, which might be almost like sacrificing the bodies to him.
* If you live in UsefulNotes/WashingtonDC or are a major rail buff, you may have figured out the plot twist about Bianca and Nico di Angelo in ''The Titan's Curse'' prior to the reveal that they spent time in the Lotus Hotel & Casino: To evade their pursuers, they duck into the UsefulNotes/WashingtonMetro. Bianca says the Metro is new to her, and she even mentions that the last time she and Nico came through D.C. (which was no less than a year prior to the events of the story), the Washington Metro did not exist. But the story is set in 2007. The di Angelo siblings are in their early teens. It seems odd that Bianca would make such a remark when the first segments of the Washington Metro system opened in 1976, well before either Nico or Bianca would have been born. Once Percy deduces that they spent time in the Lotus Hotel & Casino, it makes sense that they must have entered it sometime ''before'' construction of the Washington Metro ever started. ''The Last Olympian'' reveals that they were actually born sometime in the mid-1930s, and put in the Lotus Hotel sometime around 1941.

!Examples of FridgeHorror
* Luke's mother is still making sandwiches and kool-aid for a son that will never come home. Ever.
* You know how Percy saved Ethan? Ethan, the son of Nemesis, resurrected Kronos because of that.
* Before Rachel Eliabeth Dare became the Oracle, the previous one was soul bound permanently to her body. Her corpse was still animated, even after it had been dead for presumably centuries. Therefore the Oracle had been living forever in the mummified body that was once hers. Since the Oracle would have lasted indefinitely until someone gave her a new body (Rachel), what exactly is gonna happen to Rachel's body in a couple hundred years?
** That only happened because of the curse Hades placed on the old Oracle. Rachel is not cursed. She'll probably retire at the standard retirement age of 65.
* In book two, Percy spots a father and his two elementary school-aged daughters on the ''Princess Andromeda'', along with other guests. In book four, all the guests are gone. Percy theorizes that they [[NeverSayDie "didn't get to leave with their bingo winnings"]]. This includes, of course, the father & his daughters.
** Take it one step further and consider the ship's inhabitants: ([[spoiler: Kronos' army of monsters]]). They were most likely [[spoiler: fed to aforementioned monsters]]. Full stop.
*** In Son of Magic (Short story by Riordan's son, found in Demigod Diaries), [[spoiler: Alabaster, son of Hecate, states that when Beckendorf and Percy blew up the Andromeda, not only were monsters lost, but demigods who were allied to Kronos.]]
*** Percy considers the implications of this himself in the book - [[spoiler: while creating a diversion so that Beckendorf can finish arming the explosives, he comes across a fellow demigod and tries to warn him about what's going to happen if he doesn't get off the ship.]]
* The Labyrinth was [[spoiler:destroyed. Now, imagine how many people may have been inside when it collapsed...]]
** [[spoiler: Considering the slim chance of anyone actually getting out and not dying an excruciating death from starvation, dehydration, and exhaustion, it was probably a MercyKill.]]
* Nico spends a lot of time just roaming around, especially right after he runs away from camp when he was ten. Just think about that for a moment. A ten year old living on the streets of Manhattan alone for who knows how long.
** Add to that, he is the son of Hades. One of the Great Three, whose children are said to have such a strong smell to monsters they are safer in camp for all of the year because otherwise they would be harassed and attacked very very often. No wonder Hades offered him to live in the Underworld, that's like the only other safe place for the kid!
* At the end of ''The Lightning Thief'', Percy's mom [[spoiler: turns her husband to stone, with Percy's help.]] For the entire rest of the series, no one brings it up again, or comments on the fact that this is murder.
** Well, with a just afterlife murder is going to be far less of a crime than it is in our world.
** Bear in mind that this is a Greek epic written in modern times. People got away with that stuff all the time in those myths, especially to people as foul as [[spoiler: Gabe.]]
** I'd like to point out that the nickname ''Smelly'' Gabe was said to be appropriate for a good reason: his smell was so bad that it could hide a demigod from monsters. Percy was son of one of the three greater ones, and it still took months for a monster spending several hours every day next to him to suspect him. Being the first one, quite far from the DarkerAndEdgier tones the series got from the third onwards, that subject is never really touched but it's quite implied he [[spoiler: used at the very least to beat Percy's mother.]] More than fridge horror, is that sincerely everyone just think he got what he deserved.
** Look, let's cut to the chase and say that Gabe probably ended up in the Fields of Punishment, so......
* Imagine that you are one of the rare mortals who can see through the Mist, like Sally Jackson or Rachel Elizabeth Dare. You grow up, seeing monsters attacking the city and strange kids with powers your entire life. Because few others have your ability, nobody believes anything you say about what you've seen, and you start to wonder yourself if you're actually insane. Your only hope for mental safety is for your ability to help run you into a half-blood who might be able to explain things to you - and doing that means you've become involved in their dangerous lives...
* The Underworld/Afterlife. First, for the love of Hades, you better make sure you can pay a fee to Charon for transportation. If you can't? Oh, too bad, you're stuck until he feels nice. (And that can be up to 100 years.) Second, the judges of the underworld can show bias as evidenced by Minos meaning they might not always be fair. Third, where you go heavily depends on what the gods' opinions of you today are. If you have their favor, it might save you from the Fields of Punishment or even get you a retirement in Elysium. If you have angered a god unknowingly or hated the Olympians for them making your life miserable you can easily be denied Elysium or end up in the Fields of Punishment. Fourth, if a new group of deities takes over the laws that decide where people go can change and even those in Elysium might find themselves in the Fields of Punishment for supporting the old order. No wonder most people choose the Asphodel Fields. As Grover put it, "Just imagine standing in a wheat field in the middle of Kansas, ''forever''."
* The lives of the monsters. For the high crime of existing they're forced to fight a war in which their own kin kill them callously, over and over and over again . . .
** Not really if you think about it. Satyrs and Cyclops are monsters but don't have to fight over and over. Plus Percy and Co. were alright with having a hellhound. The only reason that monsters die is because they WANT to harm/eat/kill demigods. The average demigod is willing to leave monsters alone. Its the monsters who CHOOSE to fight and subsequently die "over and over again".
* Percy's release of Blackbeard and his pirates upon Circe's island makes you wonder, "just what happened to all the other women who were residing there and didn't escape?" You have to think that rape or murder are the most likely answers....
* Its stated in the first book that Yancy Academy had a math teacher before Mrs. Dodds, who had to leave because she had "a nervous breakdown". Add that to the trio's talk about Hades powers later in the book, and the fact that we know Hades specifically sent Mrs Dodds to find Percy....
* The hydra encounter in ''Sea of Monsters'' has Annabeth stating that fast food chain outlets are tied to a monster's life source, after the Monster Donut shop scene.
!Examples of FridgeLogic

* In the Lightning Thief movie, Persephone is present alongside Hades in the Underworld. Aside from the clear lack of research in this particular myth (i.e., Hades and Persephone in the myth had a loving, devoted marriage), there's also the fact that Persephone is present at all in the Underworld during the story, which takes place in summer. However (unless I miss my guess), Persephone only spends winter in the Underworld with Hades. In fact, her time in the underworld is the reason winter exists (at least according to the myth), because her mother Demeter, goddess of nature and harvest, misses her. What would she be doing in the underworld in the summer?
** I'm pretty sure this is a Headscratcher, not Fridge Logic...
** Because the movie sucked and they didn't know anything about Greek Mythology.
** While I can't deny the above statements, the movie was actually more accurate by accident with having Persephone in the Underworld. In the original myth, it was said that Demeter created a season of death for crops and farms. For most of the modern Western world, we would obviously assume this to be winter. But for the ancient Greeks, who lived much closer to the equator, this would be summer as it would be much too hot and dry to properly raise a farm.
** Though it also begs the question of why she couldn't just create another pearl for them to get Grover out, considering she created them in the film's verse.
* Prometheus' claim that the battle is a reenactment of the Trojan War is true, in a way - but as the AchillesInHisTent situation with Clarisse indicates, ''he was wrong about which side was which''.
* In the film, Luke says verbatim that Percy and his friends weren't supposed to leave the Underworld alive. Even though he's the one who told them about Persephone's pearls, and gave them a map showing them exactly where to find them. Unless they were killed by one of the monsters on the way there, there was never any chance of them ''not'' being able to escape alive.
