OK, there's one thing I don't quite get... if this person from Sister Location is Springtrap, how can he be? I mean, Purple Guy died inside of Springtrap years before Sister Location took place, and the spirits that possessed the FNAF1 animatronics, died by Purple Guy's hands. How can someone who made a new family attraction afterwards, be the same Springtrap we see in FNAF3? Unless the same thing happened to William too, that he was trapped in another similar animatronic, and shared the same fate as Purple Guy. Just wondering, it had me confused. William could also be a murderer, but he's not the one who killed the children in FNAF1. It's not possible, since FNAF1, FNAF2, FNAF3 and FNAF4 are past events. William must've murdered some other kids (their spirits possesing the Sister Location animatronics?).
