I'm going to list all potential plot twists (inspired by a post by a leaker on twitter. Original post undercut) for the FNAF 2 movie. I'll add to it as the movie gets closer. Please note that I don't agree with all of these. I'm just listing plot twists. Actually, most of these I really, really hope don't happen.
(Minor FNAF 2 movie leak, maybe? We have no way of knowing if Deducer is telling the truth).
Also, feel free to add to this list as you see fit.
Potential Plot twists:
Michael is William’s son.
William actually killed Mike.
Blond ghost boy (or BGB) is Vanessa’s brother.
Vanessa is a robot.
Jeremy F. is somehow related to Mike.
Mike is a robot.
Garrett and/or Abby are robots.
Garrett’s alive.
Mike is Sammy Emily.
Mike was adopted.
Mike actually killed Garrett (bite of ‘83).
Mike helped kill BGB (bite of ‘83), so William taking Garrett was revenge against him.
Mike and Vanessa are twins and/or siblings.
Vanessa was kidnapped.
Mike was a DCI victim.
Mike witnessed Charlie’s death.
Mike is Henry’s son.
Jeremy F. is an Emily.
Jeremy F. is Garrett.
Golden Duo is a thing, and its BGB and Garrett.
Garrett is the puppet.
Mike was murdered as a child, and his soul is in the puppet. So, it’s his soul/ghost saying “Come find me.”
Mike, BGB, and Vanessa are siblings.
Vanessa is actually Elizabeth.
Mike returns to Freddy’s as “Fritz.”
Mike witnessed the DCI.
Mike witnessed the bite of ‘83.
Mike was used against Henry to send him to prison.
Gregory is Vanessa’s brother.
Gregory shows up.
Gregory is Vanessa and Mike’s son - obviously if Mike isn’t an Afton.
Garrett is alive, and he’ll be the one to lay his brother to rest.
Vanessa is aware that Mike’s her brother (please ignore the novel for this one).
BGB is actually working for William.
Abby will die.
Mike will die.
Vanessa will die.
All three of the main characters will die.
Mike told on William after witnessing the DCI (leading to him losing custody of Mike), but he passed the blame off on Henry.
Vanessa and Mike were friends as kids.
Mike’s name isn’t Mike. Whether that means he’s Sammy or something else… I have no idea.
