Castle: I hate going to weddings alone.
Beckett: Well maybe we could be each others' plus ones.

Beckett: That's espionage.
Castle: More like sexpionage.

Beckett: Castle, if we were getting married, would you want to know about all of the men I've been with?
Castle: ALL sounds like a lot.

Ryan, why don't you take The Situation down to the bar?

Beckett

Beckett: Oh my God, that's Jenny!
Castle: Not just Jenny. Gyrating Jenny.

I'm not showing up solo when Lanie's bringing Captain America!

Esposito

Esposito

Castle: If you find out a man is cheating on you, how would you kill him?
Martha: Knife.
Alexis: Shoot him.

It's like the beginning of The Bachelor, but without the appletinis.

Castle

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

Castle

I know, we're nauseating.

Ryan
