Beckett and Castle in “The Dead Pool”

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 humour] 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.
