OK, so, when Sulley traps Waternoose out the simulator room, he takes the simulator room closet door of the control panels. Earlier in the film, we see Waternoose send said door to the door station.
My question is: If activated, where would it lead? Or is the red light broken, like Sulley did to the door they banished Randall through? Or is it a door simply made for the simulator room and it CAN’T be activated?
