Up on a Gotham Sky-Rise Apartment, a group of poker players grumble about the indecision of one of their players, Bennie. The conversation indicates that they are all criminals. Bennie claims he hears someone outside and sends his goons to check. While searching, the goons are assaulted by Ten.
The game continues, and Ten tosses her own exploding card onto the table, taking the bet money. She quickly tries to make her getaway but her card glider is shot and destroyed. Trapped, she hides from the angry gang while the shooting attracts Batman’s attention. Batman arrives and throws the take over to the players but they continue their shooting. Using a gas bomb, Batman manages to distract the players long enough to allow himself and Ten to escape.
Terry tells Bruce about the incident and learns that he got too close to the Derby: a high stakes poker game that’s been around since before Bruce was Batman. Bruce believes that Ten only went for her greed. Terry insists that she was only desperate but Bruce chalks it up to his youth and naivety.
