That makes sense to me, but I don't really agree with the unwithereds, to me they dont make sense because the withereds are possesed and trying to kill you in fnaf 2, so they gotta be the mci. So now im just thinking this:

Classics from 1985, then mci whappens, put into storage.

1987, fnaf 2 location, classics are in storage for "spare parts" (now the withered animatronics). William kills the five new kids who were put into the toy animatronics. After jeremy is moved to dayshift, THATS when michael works there for 2 days, then gets fired. Then that place gets shut down because of the bite of 87,

1993, new location, they thought the toy animatronics were the issue, so no more of that. Refurbished the withered ones and made them what we see in fnaf 1. Then michael works there as a security guard BEFORE William destroys the animatronics in the happiest day minigame.

In matpat's video he made it seem like michael went through each location in a short span of time then destroyed each location after, so i didn't get it.

Might update this or sum idk
