Castle, Season 3

[Castle walks into the station carrying two coffees. Natalie is writing on the "murder board", Beckett eyes at her uneasily]

Natalie:
[Takes a coffee] Thanks, Castle!

Castle:
[Stunned at her audacity] Tha-that's, I was- uh... you're welcome?

[Beckett looks shocked and distraught]

Castle:
So, where are we?

Natalie:
Ryan and Esposito are digging into Tanya Wellington.

Castle:
[Directly addressing Beckett] Mmm, what about Duke Jones? Did his neighbor confirm his romantic evening?

Beckett:
He-

Natalie:
[Cuts her off] So did a couple of other neighbors, who complained about the noise. So it looks like Duke Jones allibis out.

Beckett:
[Put out] What she said. [To Castle] Can we talk for a second?

Castle:
Sure.

[Beckett loops her arm through his and quickly leaves the room, ending up frantically dragging him into another room]

Beckett:
She took my coffee, Castle!

Castle:
It's just coffee.

Beckett:
Then what's next? My soul?! Everything I do, she does. Even when I'm thinking I can feel her in my head like some kind of a brain-eating parasite from one of her movies!
