Maybe not spoilers alarms
Last warning if you have not completed night 2, but anyway it look like the security guard and marie going to trying talking to cock "the soda cola machine" in night 3 hoping to find out some answers since he was there when shit went down with the girls. Also think she might know who purple guy is. Also the point about Golden Freddy/type 0 if the security guard going to bring her up to Marie or anyone, and if their a connection of any with phone guy.
