Fnaf 2 is a prequel we know that, but I don't think it's by that much I thinks it's by only a week. so, i think this because we know Ralf died but I think in the week before he was also recording for the second location. but oh, how are the withered animatronics that damaged considering fnaf 3 hasn't happened, yet you might say. well in the books and movie there are many different locations we don't see in the games I think that the withered animatronics are those ones possessed by the same remnant as they did with the toys. if you want to challenge my theory I willing to discuss in the comments.
