I have to chase you all night long and watch Batman take down the Russian with one punch! I have to fight my way through the legion of losers, a small mountain that thinks we're engaged, faces, both clay and two – plus I outsmarted the Joker! At the very least, I wanted to clean Riddler's clock!

Synopsis for "The Cat and the Bat, Conclusion"
Batgirl fights various villains in Arkham Asylum, while the Riddler gives her hints. She uses these clues to figure out the access code to the security control room. However, when she enters the room, she finds that Catwoman has already taken care of the Riddler. Catwoman hands Batgirl Gordon's notebook, and they meet up with Batman, who has stopped the Russians.
Batgirl leaves, knowing her father will be home soon, while Catwoman admits that she has what it takes. Overhearing their conversation, a satisfied Batgirl returns home to rest, only to be woken up by her alarm as soon as she gets on her bed.
