Gordon and Bullock get a lead on the balloon vigilante, realizing that the vigilante has more targets. The next target is Lt. Bill Cranston, a corrupt member of the GCPD. The fact that the case only started to matter and get attention after Cranston was targeted, doesn’t sit well with Gordon who confides his feelings to Barbara.
Cardinal Quin, a man accused of molesting children, is the third victim of the Balloonman. Gordon realizes who the Balloonman is after Cranston’s body falls after the weather balloon pops, and the reason for why he snapped becomes quickly apparent when Bullock and Gordon have a confrontation with him.
The show actually reveals Gotham to be a horribly corrupt place, and all of the characters are willing to accept it. Unlike Gordon, no one seems to be in any hurry to change the way things are. Everyone’s comfortable with the corruption, and the criminals aren’t going to change anything anytime soon.
