Castle, Season 3

Natalie:
Is Castle gay?

Beckett:
[So shocked that she spits out her coffee] I'm sorry, what? No. No!

Natalie:
Then you two are an item, but you're sworn to secrecy, right?

Beckett:
No, we are not an item. Why?

Natalie:
[Sighs] Last night I invited him back to my place. And he said something to me I have never heard from a man before.

Beckett:
What?

Natalie:
"No."

Beckett:
[Raises her eyebrows] No?

Natalie:
I don't get it! He's into you, but you're determined not to give into these feelings that you clearly have for him. So he fantasizes about you through his writing. It's literally verbal masturbation.

Beckett:
Uh-okay, so what does this have to do with me?

Natalie:
[Indicates her "Beckett costume"] I am not wearing this getup for my health. You're Nikki Heat, he's Jameson Rook. I need to sleep with him in the name of character research. Can you talk to him?

Beckett:
And say what?

Natalie:
[Shrugs] I dunno, give him permission or something.

[Beckett is momentarily speechless]

Beckett:
I have to go. Over there. [She disappears in a random direction]
