Ezra: Miss Parker, do you have a favorite nut?
Audrey: Excuse me?
Duke: He means other than Nathan.

Nathan: It's password protected. Come on, Parker, where's the trust?
Chief Wournos: He's trying to hack into her personal files and he's worried about trust issues.

Julia Carr: Just how did you meet these fine gentlemen?
Duke: A friend introduced us. He said they like to play poker.
Julia Carr: Did he also say they like to kidnap their opponents and drag them out to the open sea?
Duke: I'm picking up on your sarcasm.

Julia Carr: So this is who you are now. I used to think you were the coolest guy. Turns out you're just a petty crook.
Duke: No. I'm an exceptionable crook.
Julia Carr: You're a delivery boy.

Agent Howard: We're dealing with killer and terrorist in the real world, while you're here holding hands with the "Children of the Corn."
Audrey: At least I'm not like that one guy you trained that was chasing aliens, what was his name?
Agent Howard: Hey, he was a genius. What happened to him in the last few years was a tragedy, but that's besides the point.

Nathan: Don't bring her into this.
Chief Wournos: Why shouldn't I bring her into this? She's your mother. We both miss her.
Nathan: I said don't.
Chief Wournos: So you think that's it? That if she were alive today, she could fix us.
Nathan: Yeah, that it. The selfish bitch died. Left you alone with your idiot son. So you, you did your best, which meant ignoring him until he stopped looking your way for much of anything. Well, that's what you wanted. You know what, Chief, that's what you got.

Duke keeps a copy of series creator Stephen King's The Tommyknockers on his bookshelf.

Duke: I got moves that Ralph Machio, the Karate Kid himself, never dreamed of.

The Karate Kid was a movie starring the aforementioned actor in the title role, as teenager who learns martial arts to deal with bullies.
