You can't give up. That's the deal. We want the happy ending, we can't give up.

What's a great love story without obstacles to overcome? Every fairy tale has them.

Beckett: Tell me this is still part of the fairy tale.
Castle: If it is, it's a Grimm one.

What's a fiance for if not to find her future wife's current husband?

No place to get married and no one to get married to. I'd think disaster is an understatement.

Here I thought you were a one and done kind of girl.

I'm so happy for you detective, despite of who you're marrying.

Gates

Ryan: Just imagine your wedding guests are murder suspects.
Esposito: In their underwear.

Castle: She's proud of you. Wherever she is. She's proud.
Beckett: I never could have done this without you.

Bracken: Everything you are. Everything you've accomplished is because of me.
Beckett: Is that how you justify murder? It builds character?

Detective, you are radioactive. You can't even help yourself.

Smith

Between the cops and Bracken's guy, Beckett's right in the crosshairs.

Esposito

Castle Season 6 Quotes

Kate, I'm not proposing to you so you'll keep your job or because I'm afraid I'm going to lose you. I'm proposing because I can't imagine my life without you.

Castle

Oh my god! Oh my god! You're proposing!

Beckett
