Castle Season 5 Episode 3

Martha: Alexis' moving out got me to thinking. And after many hours of soul searching, I have made a decision.
Castle: Have you now?
Martha: Yes. I have decided, out of the goodness of my heart, that I will continue to live here...
Castle: Rent-free.
Martha: Please don't interrupt. I will continue to live here so that you, Richard, will never, ever be alone.
Castle: You'd do that for me, mother?
Martha: It's a parent's sacrifice.

Alexis: It's always been fine, because no matter what, I'd wake up, and you'd be there, and I'd know that everything's fine.
Castle: Oh, and when you wake up here...
Alexis: Then I'm here. And you're there. Even though there is only 5 miles away, It's not here.
Castle: Well, everything is going to be fine. And you are gonna be fine. And though I am there, if you need me here, here is where I'll be.

(at the precinct, they whisper to each other)
Castle: I so wish I could kiss you right now.
Beckett: Yeah, I know.
Castle: (while holding hands like a shake) This is me...softly touching your face, pulling you in for a long, slow kiss.
Beckett: And this is me kissing you back, running my hands through your hair.
Castle: Best handshake ever.
Beckett: Yeah.

Beckett: Alexis hates me? Is it because we're together?
Castle: I guess she feels like she's being replaced, which is weird because she's never done this before, not with Gina, not with the hundreds of super-hot girlfriends I've...
Beckett: Okay, I don't need to hear this.
Castle: Right.
Beckett: So do you think I should talk to her?
Castle: No, no, no, no. No, she'll eat you alive. Let me handle it.

(Castle is at Beckett's precinct desk)
Beckett: Who said that you could answer my phone? And why are you going through my drawers?
Castle: I was just looking for a pad of paper.
Beckett: Sure you were. Stay out of my stuff, Castle.
Castle: Your stuff? Need I remind you, I've already seen your stuff.
Beckett: Yeah, well, some of my stuff is still private.

Castle: My little girl is going to college.
Martha: Seems like just yesterday, you were checking under the bed every night, promising her that monsters aren't real.
Castle: Well, I lied. Monsters are real.
