#puppet!garrett

with that in mind, lets look at the fact that Golden Freddy is inhabited by TOYSNHK. aka the movieverse Cassidy. that slot is filled.

Its Me appeared on the mirror in front of Mike. the puppets music box played during the credits. immediately after 'COME FIND ME' is spelled out with the fnaf 2 minigame robotic letters.

mike himself even said Garrett felt closer in the pizzeria! theres a lot of evidence right now pointing towards Garrett being the puppet. he was the first kill. the first before the MCI, like Charlie

not to mention how the Schmidts seem to be replacing the Emilys in a way. the family name vs family name type thing. dont forget theres also that theory of mikes dad being Henry.

but back to my other point about Evan and Charlie, and how either of them could be the first based on what you believe, it still counts. garrett takes both evan AND charlies roles in the story. like how Vanessa takes Vannys and Michael Aftons. Like Mike schmidt takes michael aftons but also the story of an innocent family who are victims of williams killings by losing a loved one.

Garrett is both the lost first kill of the 'good' family of the story (the emilys in gameverse), AND he has the role of Evan with mike, with mikes guilt and the idea that he can avenge him or save him in a way. hes the Its Me. hes the puppet

(the family (afton + schmidt) duality also works because of the symmetry theme in the movie. also Garrett would be two game characters combined, also applying. just like how the characters i mentioned above also have combinations of two game characters as their own)
