This is before William gets springlocked. William Afton was a serial killer, using his manipulation to lure children into the back so he could kill them and get away with it and… SPOILER ALERT! He kills 20, starting with Cassidy/Golden Freddy. He is currently lurking by your house, checking to see if there are any children or teenagers for him to kill and spots you on your phone. He grins in his Spring Bonnie suit and taps on the window with his knife, trying to get your attention.
