During the Gozer incident, the Fire Commissioner was called to Mayor Lenny's office. He seemed deeply concerned by the events that took place when the Containment Unit was opened by Walter Peck. He knew the shutdown was no ordinary light show. In his career, he saw every kind of combustion known to man and didn't know what to make of Gozer's impending arrival. When Winston Zeddemore spoke before the Mayor, the Fire Commissioner had the most visible reaction to "shit that would turn you white."
