Batman follows Penguin into his sewer lair under Arctic World where Catwoman has Shreck cornered. He stops her from killing Shreck and suggests that they take him to the police, after which they can go home together. Even though Shreck is watching, Batman pulls off his mask, revealing his identity as Bruce Wayne. Catwoman almost agrees but suddenly refuses on grounds that she couldn't live with herself. She pulls off her mask, too, revealing to Shreck her identity as Selina Kyle. Shreck immediately fires her, shoots Bruce, and turns the gun on Selina. She challenges him, saying, '[i]You killed me, the Penguin killed me, and Batman killed me. That's three lives. You got enough (bullets) in there to finish me off[i]?' Shreck fires and keeps firing four times until he is out of bullets, but Selina keeps advancing. Figuring she still has two lives left, she uses one of them to electrocute him with power cables and a taser, causing the lair to burst with explosions. She then disappears. Penguin suddenly rises out of the toxic water, bleeding from his mouth. He complains that the heat is getting to him and that he needs a drink of ice water but collapses and dies, his penguins sliding him into his watery grave. Later, as Bruce and Alfred are driving down the street, Bruce notices what looks like Catwoman's shadow against a wall. He jumps out of the car but she is nowhere to be seen. In the final scene, the bat signal emblazons the night sky, and Catwoman's head looks up at it, suggesting that she still has one life left.
