I'm obsessed with Fahnuff's new theory about the timeline. It explains everything and makes the books canon and not canon because I'm pretty sure Scott had an idea and just kind of pushed forward when he realized fnaf's not going away and his ourple serial killer had to be more than just purple.
It also solves fnaf4 because if (as fahnuff and ryetoast say along with MatPat) then they're trying to build robot kids and the 'afton' house is a sim. One way or another this is yet another new au~
Genius inventors Henry Emily and William Afton meet in college at Utah state. Together they go on to plan an entertainment empire that they want to take on Disney with their animatronic creations and innovative spring lock suits.
A horrific accident ends those dreams as the youngest son of Afton ends up killed and Afton himself is maimed in one of the suits he created. After his survival, he seeks revenge against Henry, the man he blames for his accident. He kills Henry's daughter Charlotte only for him to witness her spirit being seemingly brought back to life via Henry's love. Henry, going insane with grief, rebuilds Charlotte info an animatronic.
He's a rational man, so he enlists Henry to help him study it. They've collected some and he attempts to bring back his young son. Their experiments fail. There's not enough remnant. Afton is getting older, he's in pain, his mind still broken. He puts it together that Charlie's remnant was collected in copious amounts. So he needs more. He convinces Henry to help him build the funtimes. Henry doesn't put together they're for child murder until much later when Elizabeth dies on the opening day of circus baby's. He flees, taking Charliebot with him.
Afton flees as well leaving the Afton Robotics board and Fazbear Ent board to pick up the pieces. He is still intent on continuing his experiments so he kills the hapless security guard Fitzgerald, stuffs kids in the animatronics, and ends up reaping the consequences of his actions.
It taking a more magic mixed with sci-fi approach is my favorite part. I just want to keep imagining William in the Sister Location control room just barely watching some sort of CC/EVAN bot almost waking up...then flattening mysteriously at 6am every night.
