Castle, Season 3

Beckett:
Yeah, speaking of mentor, I heard that you guys were pretty hard on Conrad last night.

Castle:
Hard on him? No, no, it was just a little friendly hazing.

Beckett:
To hear him describe it, it sounds like someone was trying to teach him a lesson.

Castle:
[Laughs in a forced manner] What? Why would I want to do that?

Beckett:
Because you didn't want him to spend time with me?

Castle:
That is completely-

Beckett:
True?

Castle:
[Drops his false humor] Yes. Fine, it's true. I'm jealous. There, I said it. I-I want you all to myself, and to have you spending time with another writer? That upsets me! And if that makes me petty, so be it. Guilty as charged.

Beckett:
[Smiles] Actually, I kinda think it's sweet.

Castle:
You do?

Beckett:
I do. And that's why you don't have to worry about me hanging around with Conrad anymore. From now on I'm a "one writer" girl.
