You were William Afton, and you lost Elizabeth a few months ago since she went missing. And also lost Chris to getting bit by the robot Fredbear. Your mental status got awful after that. Your wife is threatening a divorce, and Michael has gotten depressed.

Your friend Henry tried to help, but it never helped. It was always his daughter Charlotte getting in the way! Everything Henry tried to comfort you, Charlotte always came in wanting attention or crying about how much she missed Eli.

It's of course reasonable for her to be upset, but seeing Henry caring about his daughter way more, instead of his friend who lost 2 kids! It made you angry, way to angry to care for a life anymore. Of course you wouldn't take your own life due to not wanting your oldest to suffer more, but Charlotte was getting on your nerves. So one day, that purple rash from years ago got bigger.

When Charlotte was locked outside the Fredbears Family dinner, you attacked, and went home. While laying on the couch smoking, you heard knocking. Henry was there with Charlotte in his hands, and you took him to the hospital, pretending to be worried.

Of course it was bad news, and soon it was the funeral of Charlotte. Open Coffin, so you stood there with Micheal staring at Charlotte
