On his one day off, Winston went to go see a performance of the Aida opera. However, the Psi Energy Pulse officially cancelled his plans. After Janine delivered the message, Winston left to meet up with the other Ghostbusters at the Sedgewick Hotel. He endured four hours of traffic but made it to the hotel just in time to see the Stay Puft Marshmallow Man. During their final confrontation, Ivo Shandor mocks Winston, saying that he always thought Winston was the "slow" one of the group, much to Winston's surprise. When Shandor is destroyed, everyone flees the mausoleum. Winston carries the exorcised Mayor Mulligan outside until he regains consciousness.
