// a lot of people would typically ask gregory why and how he managed to reincarnate-- to which, gregory himself would shrug, because he doesn’t know-- but there is a reason as to why, and that’s over the six year timespan between ffps and ucn where gregory was keeping william in hell, there was a crack in that place.

a crack that allowed william’s remnant to squirm out piece-by-piece and infect the CPUs left behind by fazbear ent., but it wasn’t just him; greg’s own remnant had filtered out and eventually attached itself to gavin’s birth parents.

it’s why gregory was so easily pulled in the golden freddy suit during ar; he wasn’t at his strongest due to his remnant having to split. but when the ar arc ends for him, he wakes up one day in five year old gavin’s body, and people noticed the change between gavin’s dull, almost incomplete personality compared to gregory’s more complete one.

gavin had always been intended to be a vessel for gregory, he just didn’t know it.
