Fnaf3 phone calls confirm Bite of 83’ happens before MCI
The phone guy tapes in FNAF3 display a clear series of events
~Night 4- Phone guy mentions the springlock suits are not to be used at all due to “multiple and simultaneous springlock failures.” Most likely referencing the bite of 83’
~Night 5- Phone guy reestablishes the safe room policies and reminds the performers that they are not to bring customers into the safe room. He also mentions that the company has noticed the spring bonnie suit has been noticeably moved and reminds everyone that it is not safe to be used.
~If the “multiple and simultaneous springlock failures” does reference the bite of 83’, and the customers being taken to the back are the MCI, then due to the spring bonnie suit being deemed unsafe to use by the time the MCI is taking place, then the bite of 83’ would have to have happened by the time the MCI took place. Which means what bite victim saw couldn’t be the MCI.
