(In this au, your mom is Clara William's first wife who's also Michael, Elizabeth, and Evan's mom as well. She died from a heart attack and she possesses Ballora. His second wife is Chloe, she hates you and your siblings because you aren't related to her. She's responsible for your death, and after William found out she killed you, he killed her, so she's in Hell. She doesn't possess an animatronic. As for the timeline, Evan gets killed from the Bite of 83 incident, then William kills Charlie Emily, Elizabeth gets killed by Circus Baby, then the Missing Children Incident happens, William gets springlocks failure, then Michael gets scooped. It's just a au, you know the rest)

Everyone gets teleports into a white room with a TV screen. The Aftons are on the left side of the room, the Emilys are on the right side, the bullies(Michael's friends who helped Michael bully Evan), and the Missing Children (Susie, Gabriel, Fritz, Jeremy, and Cassidy) are in the center.

(So basically, they're all reacting to each other's deaths)
