Hey guys!! Today I have a theory from Twilight_is_Best!! Let's get to it! I'm pretty sure the timeline goes like this, MY THEORY, at the Original restaurant where their was only Freddy Fazbear, phone guy was probably a guy who trained employees and recorded them for people to hear! In Freddy Fazbears 2nd pizzeria, I think he transferred over to being a person who gives info to the player, he probably did this through the 3rd and 4th pizzeria, in The 4th Restaurant he died due to a heart-Attack from the animatronics! In Freddy's Fright, I believe the phone guys son was talking on the phone, and they looked for the old pizzeria, and found those old training tapes! So he played them for the player to hear from long ago! THIS IS MY THEORY!!
Let me know what you think!! If you have theory leave a comment or message me!! I read them all!!
