Ok, I know it sounds crazy, but it actually makes sense in many ways. If Gregory were an Afton it would partially explain why he is living inside of the Pizzaplex. Why did Gregory want to upgrade Glamrock Freddy with all of the old parts from Monty, Chica, and Roxy? Because Aftons like him are always working on creating the newest and deadliest form of the original animatronic band. He probably wanted to make Glamrock Freddy into a Frankenstein-like project. See what I mean? Could this also be why the other animatronics are after him? They know he is from the Afton family and they are still seeking revenge. Freddy believes that he can trust Gregory, but we have already seen Gregory break Freddy's trust! Freddy told Gregory that the other animatronics were his friends so Gregory shouldn't destroy them. Gregory not only destroyed them anyway, but he also began lying to Freddy about where his new and improved parts came from. This theory would also show that Vanessa is also after him because she knows his true intent. Gregory is fascinated with the Pizzaplex and the animatronics....because he is an Afton! We have been introduced to a new member of the Afton family because *Drumroll please* "THEY ALWAYS COME BACK!"

What do you guys think about this? It is just a theory and all, but it would make so much sense!
