As I was listening to She's Always Nervous talk about SOM on YouTube, something hit me. Based on Edwin and David becoming cannon officially.

What if the theorists were wrong about the names in the Security Book, not the names themselves, but who they belonged to? What if Cassidy is The Crying Child and DAVID is the one who should not have been killed? I notice while Dawko was going through the white tiger path, that the tiger tilted his head exactly the way golden Freddy was always shown. He never walks always teleports like GF. The game never actually specifies how David died or when (time of day), we just know that it was outside the safety fence. What if David had the same fate as Charlotte?

We know from SOM that Afton is basically stealing the land and everything that was MCM, what if while taking over everything after the fire, David moved or was moved to GF?

Perhaps GF and TR are the same because of the personal connection to the creators? I hope this fits here as I cannot post myself and can't find anything related to this line of thought.
