Five Nights At Freddy's: Theories, Facts, and Lore

Fritz Smith is The Phone Guy

Another very popular theory is that the night guard for Night 7 - Fritz Smith, according to his termination slip - is actually the Phone Guy himself. Supporters of this theory point out that Phone Guy offers to take Jeremy's shift at night, while Jeremy fills in for the newly-available day shift; Jeremy works on Night 6, so Night 7 theoretically would be the very next night.On the other hand, Phone Guy states on Night 6's call that they have "one more event scheduled" before the restaurant is forced to close due to an incident, and that he himself would take over the night shift "when the place eventually opens again." This implies that Phone Guy did not begin working the night shift immediately, but rather would begin if and when the pizzeria reopened. It is even possible that there was no guard necessary for that night at all, if the pizzeria closed up that very day - especially if The Bite of '87 occurred during the birthday party, causing a premature shutdown of the establishment.Furthermore, Fritz's notice of termination states, "First day on the job? Really?!?!" which likely rules out Phone Guy as he has obviously worked for much longer than just one day - unless management considered his first night shift as his first day as it would have been his first time working that particular task.It is also possible that Night 7 is simply not considered canon, much like the Custom Night from the first game, rendering the identity of Fritz Smith irrelevant to the story at large.
