6. Spirit of the Goat

Complete story — includes the ending

Ten years ago, a masked killer calling himself the "Spirit of the Goat" targets the firstborn of Gotham's elite, leading Bullock and his partner Dix to investigate the case. They find the killer, Randall Milkie, who is shot down by Bullock after Dix falls through a trap door and ends up badly injured. In the present day, Bullock finds another elite firstborn murdered by someone with the same "Goat" motive. At the autopsy, Bullock sees Milkie's trademark, which only he and Dix knew, meaning that he was not a copycat. During a debrief, Dix tells Gordon about Bullock's enthusiasm for justice, to Gordon's surprise. Bullock deduces that hypnotherapist Marks coerced both Milkie and the new killer to become the Goat to scare Gotham's rich and corrupt, leading to Marks' arrest. The "murder" of Cobblepot is also investigated, with Gordon the prime suspect as Montoya and Allen finally find a witness near the river. When they attempt to arrest Gordon and Bullock, Cobblepot enters the precinct, causing friction between Bullock and Gordon. Meanwhile, CSU operative Nygma is revealed to be in love with archivist Kristen Kringle, who ignores him. Selina infiltrates Wayne Manor and steals a component of Bruce's investigation.
