Richard Castle: What?
Detective Kate Beckett: Nothing. It's just I'm so used to you acting like a twelve year old all the time it's kinda refreshing to see you as a father.

Richard Castle: Do I look like a killer to you?
Detective Kate Beckett: Yes, you kill my patience.
Richard Castle: [Castle to Alexis] Okay, you know, I - you know what? I think it's time we reset the parental controls on your computer.

[seeing Beckett's expression, he trails off]
Richard Castle: What I just said was not confusing enough for your face to do what it's doing.
Detective Kate Beckett: [on the phone with Perlmutter] He just hung up on me.
Richard Castle: There's a reason he hangs out with dead people.
Detective Kate Beckett: [Beckett to suspect] Don't leave town.
