Hello, Internet. Welcome to True Theory, the only series on the internet where you’ll hear nothing but the truth. No lies to be found here. Alright, today’s theory. You know William Afton? Wholesome owner of Fredbear’s Family Diner? MURDERER. Boom. Weren't expecting that, huh?!! “But Mack! Where’s your proof?” I hear you typing in the comments…Well allow me to burst your thin little hand soap-bubble. My source has told me of a long time secret hidden by the Afton and Emily families.
