Castle, Season 6

Castle:
You know it must be weird for you, being back here at the precinct, working a case.

Beckett:
Yeah. Yeah, it is.

Castle:
Yeah, especially since McCord's little gag order prevents you from accessing your most effective investigative tool. [Hands her a cup of latte] Me.

Beckett:
[Taking the cup] Yeah, you are a tool, all right. Wow.

Castle:
So, uh, she's not here right now, so what's the harm in giving me a little tidbit?

[Beckett pauses, looks up at Castle, then the cup, and then back at him]

Beckett:
This is a bribe. Castle, you're bribing me with a latte?

Castle:
No, I am not. Come on. Don't be ridiculous.

Beckett:
This is low, even for you.

Castle:
Look, I can solve this. I just need a little more to go on.

Beckett:
Castle, you're not gonna "Castle" me on this one.
