Bullock is heading home on a snowy night, when suddenly a masked man nearly runs him over. Later, the Bat-signal lights the sky and Batman arrives only to discover that Bullock sent it, not Gordon. Bullock explains that someone is sending him death threats and it could be anyone. He does not want to go to the department for help, given his checkered past. Batman agrees to help and takes some of Bullock's file cases. As Bullock heads back to his apartment, his landlord, Nivens, complains to him about his filthy habits.
Bullock and Montoya go after a gang of robbers. Bullock chases one to the roof who nearly shoots him but Batman knocks the thug unconscious. An ungrateful Bullock tells Batman to meet him later. Batman arrives at Bullock's apartment and thinks that the culprit is trying to scare Bullock, but not kill him. A professional would have killed him in his home, not on the street.
Batman approaches a distressed Bullock at work and brings up Vincent Starkey, a.k.a. "Vinnie the Shark", a drug dealer Bullock arrested 8 years ago. Vinnie is out and seeing how Bullock cost him an empire, he and Batman suspect him. Bullock goes to see Summer Gleeson, who might know something having done a piece on crack houses. Summer is reluctant to help, but Bullock goes through her files without permission. When Summer catches him, she is furious and kicks him out.
Batman has discovered where Vinnie the Shark is and takes Bullock there. They take down Vinnie and his thugs, but Batman is not sure Vinnie is the suspect. At police headquarters, Bullock interrogates Vinnie, who maintains he knows nothing about the letters. Bullock is not convinced but he cannot do anything.
Bullock returns home, where the masked man appears, ready to shoot him. Batman stops the culprit and unmasks him revealing Nivens. Nivens was trying to scare Bullock away because he was fed up with him. As Nivens goes hysterical, Bullock mentions he was thinking of moving anyway. Bullock thanks Batman, but Batman just leaves.
- Brutal Honesty: Bullock makes no bones about his view of Batman, even when asking for his help:
Let's get something straight form the git-go, I think you're a freak and a menace, and those are your good points. But the Commish
says you serve a purpose, so I go along. Batman:
I appreciate your honesty.
- Dirty Cop: Bullock enlists Batman's help in a private matter, claiming he does not want internal affairs looking too closely at him. Batman immediately asks if he is on the take; Bullock vehemently insists that he does not take bribes, but he admits he might be a little careless with suspect rights and police brutality.
- The Dog Was the Mastermind: Bullock's landlord.
- Grudging Thank You: Bullock gives one to Batman.
- Irony: The whole episode was the result of Bullock's landlord wanting to force him out of the apartment and find a more desirable renter. As he's taking him away, Bullock admits he was thinking of moving out anyway.
- Jerkass: Detective Bullock seems rough around the edges, and his main claim to fame was merely distrusting Batman. Then he gets his Day in the Limelight and spends it proving that he is nothing short of an asshole. Gleeson offers him help figuring out who tried to kill him, but has work to do and asks him to wait a half hour before she shows him whatever he needs to see. Bullock decides to break into her office and dig through the files like a burglar instead of just waiting like he agreed to.
- Merry Christmas in Gotham: Batman is asked for help by, of all people, Harvey Bullock, and the Aesop is that you should always be helping people, even if they don't like you.
- Not So Different: Bullock suggests this to Batman while explaining that he (Bullock) doesn't want Internal Affairs involved in a case because Bullock is implied to have leaked information to the press and violated the rights of suspects. Batman rejects it but considering that a few minutes later he intimidates a drug dealer for information by dangling him in front of a car...
- What Does This Button Do?: Harvey Bullock asks this about one of the Batmobile's buttons. Batman half-grins and says, "Passenger ejector seat".
