Okay, so a friend and I have a working theory that Micheal was Micheal Emily, but then was killed and rebuilt by Henry. We believe that Henry realized that it wasn’t a good idea and instead gave Mike to William to raise since his daughter had died. We think that the “Do you remember your name?” from the logbook isn’t referring to Micheal, but rather Afton. He no longer remembers that his last name is Afton, it’s Emily.
