Joker: Get back here, Harley!
Harley: But I want to know who he is, sweetie.
Joker: No one's who they think the are, my dear. Why spoil the fun?
Batman: It was all a lie. There's nothing wrong with you.
Joker: Nice of you to say, but you of all people should know there's plenty wrong with me. Take my blood, for example. I wish somebody would, this stuff is killing me.
Batman: Why should I care?
Joker: Because now there's a teeny little bit of me in you too, Bats. Oh come on. Don't tell me it's not what you always wanted. Look, we're running out of time. I need your help. I nearly had a cure. It was so close, and then it was taken from me.
Batman: So we both die. I'm fine with that.
Joker: Are you? Imagine sucking down that last breath knowing that Gotham is doing the same.
Batman: What are you talking about?
Joker: Oh, didn't I say? I've spent weeks shipping samples of my blood to emergency rooms all over the city.
Batman: So that's Protocol Ten, poison Gotham. I expected more.
Joker: Protocol Ten? Never heard of it. Hold tight. I'll be in touch!
Batman: I'm listening.
Joker: Is someone feeling a little down?
Batman: What do you want?
Joker: Oh Bats, cheer up. It won't kill you. Oops.
Batman: Where is the cure? Who has it?
Joker: I had our cold-hearted friend Mister Freeze making it, but he's gone dark on me.
Batman: I'll find him.
Joker: I'll bet you . . .
Batman: Alfred, Joker's poisoned me. He may have poisoned Gotham too. Mister Freeze has the only cure.
Alfred: What are you waiting for then? He's in Arkham City. Find him.
Batman: If only it was that simple. He'll be somewhere cold. He needs to be kept at subzero temperatures to survive.
Alfred: I don't wish to worry you, but it is the middle of winter out there.
Batman: I noticed. I've calibrated the cowl to track heat signatures. I'll find the coldest point in Arkham City.
Freeze's lab must be this way. I'm definitely heading toward the coldest point.
Joker: Woooo. I can't believe I didn't think of this earlier. A hotline straight to my bestest friend in the world. Just think, I can call you up whenever I get bored. I think our relationship is really maturing here. The next thing you know is we'll be exchanging emails or meeting up for romantic dinners.
Political Prisoner: Batman, Please help me!
Batman: The old GCPD building? Freeze must be using one of the old forensic labs. I've got to get in there.
Inmate 1: What's stopping it?
Inmate 2: The door. It's shut tight.
Inmate 1: So what now?
Inmate 3: You two keep trying to get in. I'll blow their faces off if they try to get out.
Inmate 1: And then what? We just grab Freeze and take him back to the Joker?
Inmate 4: Sounds like a plan.
Inmate 5: Think you can hide from me? Grenade!
Inmate 6: Oh God. Everyone, get your asses over here now!
Inmate 7: Wake up! Do you hear me? Wake up! Show yourself, chicken!
Inmate 8: Huh?
Inmate 9: It came from over here. I'm sure of it.
Batman: Throwing another Batarang will give away my position.
Inmate 10: Is that supposed to scare me? Come on, where are you?
Inmate 11: I'll cover this way.
Inmate 10: What? I'm sure it came from over there.
TYGER Helicopter: Target is lit. I repeat, we have positive on Batman.
Inmate 10: He went above us.
Inmate 11: What?
Hugo Strange: All prisoner must surrender themselves for psychological profiling at regular stages. Refusal will not be tolerated.
Inmate 12: He's gone. I lost him. Find him now!
Inmate 13: Huh? It came from over here. I'm sure of it.
Inmate 14: There you are, Bat. Get over here. I've found Batman!
Inmate 15: What?
Inmate 16: Over here! I got him!
Penguin: Can you hear me? What's going on? Oh, for the love of . . . If any of you idiots at the GCDP are still capable of breathing, switch to channel Puffin-Zero. Do you understand? Puffin-Zero, now!
