Fnaf Sister Location
Introduction
Hi I'm writing this theory book for fnaf fans and theorise about fnaf sister location.
First dialogue
At the beginning of the game the man says William afton meaning you would play as purple guy but at the cutscene after golden Freddy mode on custom night Michael says"they didn't recognise me" meaning you play as Micheal afton (purple guy's son).
Last cutscene
In the last cutscene of golden Freddy mode the character talking is Michael afton (purple guy's son) says "I've done it father" referring to freeing his sister from baby. But why if he safes his sister, kills his brother. And why at the end springtrap popping out. That would mean Michael afton is springtrap rather than William afton (purple guy).
