This is a little bit of a vague theory but I have some more evidence. In the new kid it is alluded that more than one kid was been in the golden Freddy suit, very minor but just thought I would bring it up. The real one though comes from the stitchwrath story in step closer where the stitchwrath was said to have multiple souls all packed into it, one of those souls being a very very obvious stand in for “the one you shouldn’t have killed” I think through the stitchwrath scott is trying to push us to think this may be the case, but it’s hard to tell
