Speaking of sweet...who's your date to Ryan's wedding?

Castle: I always liked your legs, but now I respect them.
Beckett: Yours aren't so bad either. For the next police picnic, we should enter the three legged race.

If we ever get out of here, we should seriously consider joining the circus.

You would make a terrible conjoined twin.

Castle (to Beckett)

What if we're in some psycho's lair and have to kill each other off like in Saw?

Would it kill you to let someone open the door for you for once?

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.

Castle Quotes

Castle: How do you know when you're in love?
Beckett: All the songs make sense.
