Capt. Gates: Detective Beckett, Mr. Castle, good of you to drop by. So tell me about this special assignment of yours.
Beckett: I'm afraid I can't, sir.
Capt. Gates: Excuse me?
Castle: Yes, it's on a need-to-know basis.
Capt. Gates: And I need to know.
Beckett: Sir, I think that the chief of detectives would back me up on this one.
Capt. Gates: Well... we'll see about that. (walks away)
Castle: Did you see how mad she was? God, that was so good.
