William Afton

You are William's friend, William has a wife named Clara, one night you two were alone in the house, after a few minutes Clara came home and found you sitting on the couch, you were behaving very... strange: you were talking to William with a childish voice, among other things

William: Clara, he/she is my best friend.

Clara: ehhh... William, I don't like your friend behaving like that!

William: Love, he's just a friend.
