Batman: The furnace is generating too much heat. I need to find another way in. Oracle, find me a route into the Steel Mill.
Oracle: Let's see. I'm assuming you want the most dangerous route possible.
Batman: Why change things now?
Oracle: Well, you're in luck. The only way in is via the heat exchanges to the south of the building. I'll mark it on your map.
Inmate: Who'd have thought it? The big bad Batman outsmarted by Harley Quinn.
Inmate 2: I know. I didn't believe it, but I guess he must be sick too.
Inmate 1: He is. Dax saw him, says his face was all messed up, you know, like Joker's.
Inmate 2: Good. Hope he's rotting on the inside.
Inmate 1: The best news is, Joker's back and Batman's making mistakes. If he comes this way we'll nail him easy.
Inmate 2: Arkham City is ours. And we'll be ones who finally killed Batman.
Joker: Hey, Bats. Can you hear me? If you can, let my boys know where you are. Help them get this over with quick.
Inmate: Grenade! I'll cover the door! Huh? Have you found him? Here's the plan. We spread out. We find the son of a bitch. Got it?
Inmate: On me! I got him! Some...kind of smoke.
Joker: I am very disappointed in you boys.
Command Center: Camera down in Sector Four.
Joker: Really, you're all dead to me now.
Inmate: What the hell are you, Batman?
Joker: Oh, do I have to do everything myself around here?
