I don't even know how to do this!

Beckett

Really? You're going to play the jealousy card now?

Beckett

Are you wearing makeup?

Esposito

Castle: You and I were just friends for four years.
Beckett: You were trying to sleep with me the whole time.

Apology not accepted.

Esposito

It is what it is.

Ryan

You just want me to take my shirt off again.

Beckett

Beckett: Castle, what do you think of this one?
Castle: Sexy.
