This has been ticking me off for a while, How people think that the voice at the true ending of Five Nights At Freddy's 6 - Pizzeria Simulator is William Afton AKA "Purple Guy". It isn't. William wouldn't bother doing that, and he is pretty much Scraptrap. The voice belongs to the founder of Fredbear's Family Diner/Freddy Fazbears Pizza, Henry Emily. Why? Because why the heck would The Puppet (Aka "The Marionette") be related in anyway to afton? Trust me, I've read all the books, and im pretty sure that afton died in the Spring Bonnie suit due to a spring-lock failure. Henry died of natural causes, but supposedly brung many dark secrets to his grave. Charlotte Emily AKA Henry's daughter, in the mini game she died, only for her soul to move into the puppet to inherent for many decades to come. Want proof of clues? Links below will tell you EVERYTHING (Just as long as you're a good theorist like me.)

Henry even called him "Friend")
