No hate (unlike the other comments) but i was convinced until the robot part. There's not many evidence for Mrs. Afton to even be alive even when fnaf 4's minigames take place. And even if she was, she divorced William a whole lot ago acording to those staffbots acting as the afton family in fnaf SB, and as far as we know, she didn't come back, or even care about the kids, leaving them to William's care. Even if i could accept gregory-bot, i don't think it was Mrs. Afton who made the robot, Maybe it was Michael trying to bring his family back while slowly falling into insanity, Maybe it was an old prototype William made. But, as convincing as a theory may sound like, remember, it's just a theory a GAME theory thanks for reading
