Robin discovers that Gil Mason is working with the mob and goes after him, running into Batgirl. They discover Batman has been captured and Mason is working with Two-Face to frame Commissioner Gordon. Batman and Robin now have to trust in their new ally.
- Death by Secret Identity: Gil is in a coma, but nonetheless he's incapacitated so that he can never reveal Batgirl's identity as Barbara.
- Never Say "Die": Gil Mason is in a coma by the end of the episode and never returns.
- Pin-Pulling Teeth: When told to "bury" Batman, Batgirl and Robin, a thug pulls the pins off two grenades at once using his teeth.
- Wounded Gazelle Gambit: In Part 1 a rally seemingly being held to raise bail for Gordon, Batgirl saw a car full of black-masked gangland assassins suddenly tear through the plaza and open fire with machine guns on the speakers' stage. Gil Mason was nearly shot, but the bullets hit the podium instead of him. Batgirl chased one of the assassins into an alley and managed to unmask him, but he escaped just after she got a good look at his face. In Part II, Robin reviews a videotape of the rally in the Batcave and gets suspicious when he plays the tape in slow motion and sees Mason duck behind the podium before the masked men reveal their guns to the crowd; his suspicions are confirmed when Barbara visits Gil's apartment and sees the very assassin she unmasked lounging in Gil's armchair! It turns out that Mason has been secretly cooperating with Two-Face, and the men in masks were Two-Face's own goons; Mason and Two-Face had arranged for the conniving deputy to be shot at so that no one would ever suspect that Mason had been in on the plot as well.
