Just a quick thought; we all know the Immortal and the Restless soap opera transitions in Sister Location, right? We know that the man is a parallel to William and the woman is a parallel to Clara. Now, one thing that keeps coming up in those segways is "The baby isn't mine." Plus, in the Survival Logbook, Cassidy keeps asking someone, "Do you remember your name?" Like the receiver's name changed or they just forgot their name. There's another spirit speaking as well through reversing letters and numbers. What if Cassidy is communing with Evan within the pages of the Logbook? We know they share the same suit. There's a parallel to that in one of the books. Plus, Evan continually speaks to Michael, saying "It's me" over and over again. Who's to say he isn't using his brother's logbook (on the first page, Michael wrote his name)? If it is Evan she is talking to (remember, we also see a lot of fnaf 4 easter eggs, in which we play as Evan), then that would mean that "Evan" isn't his real name. Either that or he forgot his name. Either that or he was losing himself and Cassidy was trying to bring him back, but then again, Cassidy is the "Vengeful Spirit" that traps William in his own personal Hell and torments him for the suffering he has caused her and others. I doubt that she'd be concerned about Evan remaining Evan.

Now, we've heard William speak, Michael speak, and Elizabeth speak, but not Evan or Clara. Both Michael and Elizabeth have their father's native accent, alluding to him being their biological father. Not always the case, but there's no other man with that accent in fnaf as of yet. As we all know, Scott doesn't do coincidences. What if either Evan was adopted or Clara was a single mother when she married William? I will keep the story the way it is, with Evan being William's biological son, but it's something to think about... I may do another story about that theory. May just be a one-shot. Let me know if y'all would like to see that.

Thank y'all for reading, saving, commenting, and following! God loves y'all!
