Fanfic: George Weasley And The Computational Error
The universe knows that J. K. Rowling is bad at math and it is used to ignoring the computational errors it comes across. And if an extra Weasley twin is running around in 1989, it probably won't notice—even if that twin happens to be forty years old and from the future.Basically, a George Weasley goes back in time to save Fred fanfic with some bizarre twists on the Peggy Sue genre. There is no mental time travel, but the person who sent him back makes it so that whenever Fred drinks pumpkin juice, Old George starts or ceases possessing his younger counterpart. Also, George is not allowed to let the fact he's a time traveler leave his head for a year or the universe will notice he doesn't belong and it'll kick him out. These two facts combine to make no one trust this "Saintlike One" who can possess Young George and knows far too much.Written by pisoprano. You can read it here.
Becoming the Mask: George becomes legitimately crazy from being possessed by Voldemort
Bittersweet Ending: Dumbledore and Voldemort are the only casualties, but Old George ends up insane in the process (though it is implied that he'll eventually recover).
Blatant Lies: George does a lot of this, primarily when acting as Charlemagne and when he's possessed by Voldemort.
Break the Cutie: Almost everyone who is cute in any way gets this eventually.
Bullying a Dragon: Old George and the young pranksters annoy Voldemort at every available opportunity.
Chekhov's Gun: The fact that one of the only things George was able to take with him was his wand. It is used multiple times to confirm his identity.
The fact that George has an undetectable extension charm on his pocket.
Convenient Coma: Anytime George possesses himself, he goes into one (unless he's used Legilimency and the Imperius Curse on himself before hand). It comes in handy while looking for a unicorn.
Crappy Holidays: When George is more or less alone on Christmas. Subverted for April Fool's Day.
Crazy-Prepared: It's implied that Old George kept Gryffindor's sword in his pocket for a year, and that was before he was even possessed by Voldemort. Of course, he may have had Fred leave it in his pocket at a later date, but he's still over-prepared.
Old George also appears to be this when Fred, Young George, and Lee try to prank him. Of course, almost all of the pranks they tried were attempted by him before, but even when they make a truly random prank, he still takes it in stride.
Demonic Possession / Symbiotic Possession: Fred, Young George, and most people when they find out about the Saintlike One think he's doing the former when it is actually the latter. It's definitely the former when it comes to Voldemort, though.
Figure It Out Yourself: George sends Dumbledore on the Horcrux Hunt without all the information, as that will make the Saintlike One seem even more suspicious than he already is. This backfires with a vengeance because George forgot that the first Horcrux Dumbledore found on his own was the ring that killed him. Afterwards, George is more forthcoming.
Fighting from the Inside: When learning Occlumency, Young George does this. Old George also does so against Voldemort, eventually failing.
Impersonation Gambit: George claims that he's Mundungus' long lost friend Charlemagne. It helps that George has heard Dung's stories about him, and the fact that Charlemagne has and will continue to be missing for decades.
Inane Blabbering: When George pretends to be insane. And when he actually goes insane.
Infraction Distraction: Mundungus thinks George had him visit Azkaban to steal the wands of convicts. While that is useful, the real reason is so George can contact Sirius and convince him to escape.
Is This a Joke?: George's initial reaction to being offered the chance to jump back in time.
Subverted with Chapters 10 and 11, which Word of God says were originally part of the same chapter, but she split them to lessen the whiplash a bit.
Mundane Made Awesome: Pumpkin juice. Also, grading papers as a means of secret communication and making Voldemort bored.
Mysterious Employer: George is sent back in time by a mysterious voice known only as "The Trickster." He eventually finds out that it's a time traveling Lysander Scamander who wants George to send someone else back in time and to save his grandma.
Mysterious Past: Since George isn't allowed to talk about where he comes from, he's got one of these in all of his various personas.
Obfuscating Insanity: Lots. George pretends to be insane so that he's sent to St. Mungo's instead of Azkaban when Mundungus and Aberforth find out he isn't who he says he is. It turns into a running joke that everyone claims George to be insane, which makes it all the worse when he has to fake insanity to Voldemort and eventually become legitimately insane.
Only One Me Allowed Right Now: Why most people can't use long-range time travel. The universe acknowledges twins as an exception and since it's bad at counting anyway, it just thinks the miscount is its own fault.
Apparently he has seen his universe's version of A Very Potter Musical, if him calling himself "Harry Freaking Potter" and his legitimate mad babbling before Voldemort sends his snake after him is any indication. And he may or may not have shown Fred and Young George his memories, considering that their imitation of the troll incident has them dressed up like the actors in the musical.
Spanner in the Works: George is usually his own spanner, but occasionally someone else messes up his plans too. Also deliberately subverted with the case of Hermione, who was petrified before she did something to throw off George's plans.
Stable Time Loop: Mentioned by name and averted. The whole point is to break this in such a way that the universe doesn't notice until too late.
Stupidest Thing I've Ever Heard: Tonks says this about Young George being possessed. And about the Saintlike One wanting her to rob Bellatrix's vault for him.
Trapped in the Past: Well, more like trapped in the present after George breaks time travel for everyone to send Remus farther back.
Younger than They Look: Invoked so that George's story of fighting during the war against Voldemort while a teenager holds water. Also noted as being the case for Severus Snape, which doubles as an Actor Allusion.
