- James Gordon: Where is he? Where is Potolsky?
- Isaac Steiner: Those hypocrites! Empty altruism will not erase what they've done. They must pay.
- James Gordon: Who? Who must pay?
- Isaac Steiner: WellZyn. Wayne Enterprises. Everyone will finally see them for what they are.
- James Gordon: How? Where's Potolsky headed?
- Harvey Bullock: What's 'altruism?'
- Harvey Bullock: Where the hell have you been?
- James Gordon: Personal business.
- Harvey Bullock: You disappear in the middle of a case, and you can't even tell me why?
- James Gordon: That's what "personal" means.
- Nikolai: I assure you, in my country we have all modern conveniences. Only difference ladies. Ladies are in kitchen or in bed, depending on their talents.
- Fish Mooney: I bet your mother was a lousy cook.
- [first lines]
- Alfred Pennyworth: Fancy a stroll? It's a lovely day. Stretch the legs, breath of fresh air.
- Bruce Wayne: I'm busy...
- Alfred Pennyworth: I got a question for you, Master Bruce. What if all of this was a complete and utter bloody waste of time? What if you never discovered who killed your mom and dad? Hmm? What if you never get to wreak revenge?
- Bruce Wayne: I don't want revenge. I wanna understand how it all works. How Gotham works.
- Alfred Pennyworth: Well, you'd have more chance digging to China with a teaspoon.
- Stan Potolsky: [taking over the television broadcast] Good evening. This is a public service announcement on behalf of all living creatures. You've heard of a drug called Viper? That's me. I made it for Wellzyn, a subsidiary of Wayne Enterprises!
- Bruce Wayne: Is this true?
- Molly Mathis: Of course not, Bruce! This man is obviously insane.
- Stan Potolsky: I'd hoped that a demonstration using street people would suffice. But it seems that bad things only truly happen when they happen to important people... like you!
- [last lines]
- Carmine Falcone: I couldn't help but overhear that aria you were humming.
- Liza: [taking out her headphones] Oh, yes. It's my favorite.
- Carmine Falcone: Mine too.
- Liza: Ah, well, there you go.
- Carmine Falcone: I'm sorry. I just... I didn't mean to bother you. My mother sang that to me when I was young. Her whole life, she sang that to me. I hadn't heard it in a while, and I had to smile because you look... Anyhow, sorry. I'm rambling on.
- Liza: No, that's okay. Do you wanna listen?
- Carmine Falcone: Well, yes. Sure. Thank you.
- Liza: Let's sit down...
- James Gordon: Wait a minute. One guy did this? Stole your ATM over milk?
- Cashier: Little skinny-ass dude, guitar case, drinking milk like there's no more cows. "Don't vex me, mortal", he says.
- James Gordon: I'm sorry, what?
- Cashier: Listen, if I had a dollar for every hobo skeez that walks through that door thinks they're God, I wouldn't be here. But this son of a bitch, he wasn't fooling around.
- James Gordon: All right, you get a description of the vehicle? License plate, something?
- Cashier: He didn't have a vehicle.
- Harvey Bullock: Then how'd he pull your ATM from the wall? How'd he take it away?
- Cashier: That's what I'm telling you, man! He pulled it out of here with his bare hands!
- [Gordon and Bullock trade an alarmed look]
- Isaac Steiner: Yes, I know Stan Potolsky. He was a student of mine, a very brilliant student. He may be a biochemist, but philosophy is a passion of his.
- James Gordon: You stayed in touch?
- Isaac Steiner: Yes.
- James Gordon: What do you know about Wellzyn firing him?
- Isaac Steiner: Stan's work for Wayne Enterprises led him into some dark moral corners.
- Harvey Bullock: Wellzyn told us Potolsky made shampoo. Where are the dark moral corners in that?
- Isaac Steiner: [bark of laughter] Shampoo? They say that, do they? No, no, Stan designed pharmaceutical weapons, to be used by combat troops. Drugs that worked on an epigenetic level. Imagine an army made up of soldiers so strong, that they can tear a man in two with their bare hands.
