First appearing in "Beasts of Prey", Gordon and Bullock investigate the murder of missing model Grace Fairchild after Gordon accepted the case from police officer Len Moore; Gordon later realises that he was ordered by Commissioner Loeb to give him the case as an act of vengeance. In "Under the Knife", Gordon publicly tells to the public the details about him and his murder spree. He and Bullock discover his background and his father. During that time, Skolimski encounters Gordon's ex, Barbara Kean, inviting her in his house. Although he attempts to kill her, he saw something more in her, but Barbara tries to resist, forcing him to bound her in torture room. After freeing Barbara, Jason forces her to tell him whom to kill next. In "The Anvil or the Hammer", Gordon tries to find him, through the Foxglove club in which one member Sally (who was kidnapped by Jason before his murder spree, only to be spared by unknown reason) reveals that he is in Gotham Royal Hotel. Gordon and Bullock then go to Barbara's parents mansion, finding her parents murdered. Gordon finally shoots him and saves Barbara, albeit in shaken psychological state.
