- Gideon: Special agent Ness has suffered severe hypoxia. It will take some time to reverse his brain damage.
- Nate Heywood: You can undo brain damage? Why haven't you helped Rory out?
- Gideon: Who says I haven't?
- Mick Rory: By the time you find Ness, he'll be swimming with the fishes.
- Nate Heywood: Mick, you beautiful genius, that's it.
- Mick Rory: About time someone noticed.
- Amaya Jiwe: Aren't you forgetting something? Nate and Ray?
- Mick Rory: Those idiots have done nothing but get in the way.
- Ray Palmer: Uh, guys, we're - we're standing right here.
- Mick Rory: Well... get in the back.
- Nate Heywood: [in a Scottish accent as Sean Connery] Isn't that just like a thug? Brings a Tommy gun to an ion blaster fight.
- Eliot Ness: You expect me to believe that Al Capone is gonna be taken down by tax evasion? Sounds screwy.
- Ray Palmer: Actually, it'd make a pretty good movie one day.
- Damien Darhk: Mr. Capone... It's a pleasure to make your acquaintance.
- Al Capone: I cancelled tickets to the opera, 'cause I heard there was new players in town. No one told me it was Halloween.
- Eobard Thawne: Well, it's more like Christmas.
- Damien Darhk: That's - I like that, that's very good.
- Nate Heywood: What just happened?
- Ray Palmer: Well, it's the strangest thing. Uh, two cops just escorted Eliot Ness to the bureau.
- Nate Heywood: They're not escorting him to the bureau. They're gonna throw him in the river.
- Ray Palmer: What?
- Nate Heywood: Ray, 1920s Chicago PD was the most corrupt police force in history. Almost all of them are on Capone's payroll. Did you or did you not see "The Untouchables"?
- Eobard Thawne: My speedster weapon. Impressive. Unfortunately for you, the effects are only temporary.
- Jefferson Jackson: What did you do with Stein?
- Eobard Thawne: Oh, I wouldn't waste my energy worrying about him right now.
- Jefferson Jackson: Whatever you're gonna do, do it now.
- Eobard Thawne: In a rush to die, are we?
- Jefferson Jackson: I'm not talking to you.
- Al Capone: [to Martin] Don't be so glum, professor. You'll be in good company at the bottom of the river. Thieves, snitches, do-gooder cops, they've all run afoul in my organization, but you... I've never had to whack a professor before. Guess I'm moving up in the world, hey, boys?
