We're in handcuffs. Kinky.

Don't get up yet, stay in bed.

Castle: We're gonna catch this guy.
Beckett: Yeah, like we caught the guy who shot me.

Castle: I know what the paper dolls mean!
Gates: Mr. Castle, now is not the time for your theatrics.

You got this.

Castle (to Beckett)

She's spinning out of control. Losing her ability to cope.

Beckett: Do you know what he has that most men don't?
Castle: A Josh Groban cd?
