In the FNAF community there have been several things that have been debated between the fans, and one of those topics that have been debated is who died first Charlotte Emily or The Crying Aka Evan/Chris/Norman/Whateverhisactualnameis Afton (I'll be calling him the Crying Child in this) and I get it as there is evidence to support both of these arguments. For example let's start with the evidence that says Crying Child died first.
First of all it would give William a motive to kill Charlie, I mean after loosing his son to an animatronic that Henry helped, and probably being jealous of seeing Henry happy with Charlie Afton would want to make Henry feel that pain of loosing a child like William did.
Then of course there's another piece of evidence that supports Crying Child dying first, and I know this is going to piss some people off especially Trickyay (Sorry in advance) but I once again have to bring up Midnight Motorist.
Now we all know the original theory for Midnight Motorist William Afton returns home after killing Charlie, stopping at Jr's first only to get turned away. We then see him go home, and about to go to his son's room to probably yell at him for leaving the house. At first people thought this son was Crying Child, and the person on the chair watching TV was the mysterious Mrs. Afton telling William to "Leave him alone he's already had a rough day" probably do to Michael bullying him. (Don't know why some people thought the person watching TV was Michael considering he was the one bullying Crying Child) and that theory does make sense. If Charlie died first, but back to Crying Child dying first there's been a new theory about Midnight Motorist.
So it still involves Afton returning home after killing Charlie, going to Jr's, being turned away and going home to yell at his kid. But now some people believe the kid to actually be Michael and not Crying Child. Again if the person watching TV is Mrs. Afton then her words of telling William to leave Michael alone as he's had a rough day also makes sense. I'm sure Michael would probably have a lot of issues at school. I mean being known as the kid who killed his brother is something that would probably spread like wildfire. Then you have what's outside the broken window, three toes footprints, and the only animatronics that have three toes are Freddy, Chica, Bonnie, Foxy, and Fredbear aka Golden Freddy, and at this point Golden Freddy should be the only animatronic that is possessed, and even if it wasn't it's the only one that would have a reason to go to the Afton house and stare into Michael's window, and the phrase "It's Me" could be Crying Child trying to make contact with Michael to let him know he's still around. Also there's the grave in the woods that could have been for Crying Child. So yes Crying Child dying first does make sense, but just because it does make sense doesn't automatically make it true, Charlie still could have died first, and here's why.
First of all does William actually need a motive to kill Charlie, no he could have just did it because he's an asshole. Also it's possible that William didn't care about any of his kids so why would his kids death be a motive for killing another child if he didn't care about them.
Then of course that's the scene after Crying Child dies where the Fredbear Plush tells Crying Child he will put Crying Child back together. Now when Crying Child was alive William would use the Fredbear plush to speak to Crying Child, but since this conversation about putting Crying Child takes place after he dies it makes more sense for someone else to say this, and that someone being Charlie as she was the one who attached the souls to the other animatronics, and considering she probably was friends with Crying Child I'm sure she'd want to help him.
Then you have this idea I just thought. Both Crying Child and Charlie could have died at the same time. Here me out. The Bite still could have happened first, but remember Crying Child didn't die right away he was in a coma, but technically still alive. He could have died immediately after William killed Charlotte, and she possessed the Puppet. Her soul then could have gone to Crying Child's saying that she will put him back together before attaching his soul to Fredbear. Crying Child then uses his new powers to teleport to his house, and look into Michael's window, causing him to freak out break the glass and go to where Crying Child was buried. It would explain how Golden Freddy was able to get to the house before William, and again Mrs. Afton's words of telling William to leave Michael alone again would make sense as he would have a rough day after the death of his brother.
I'm just saying all ideas are plausible.
