Beckett: Definitely not. You are exactly her type. And the last thing I need to watch someone from my past trying to seduce my fiancée while talking about the goddess that lives in her hoo-ha.

Beckett: You didn't call because you were in a private room, making out with a geisha?

Perlmutter: What you don't know about postmortem analysis could fill a book, Mr. Castle. In fact, it has. Numerous times.

Saya: This is not what you think Detective Beckett.
Beckett: That's what all guilty people say. Is this a badge?
Castle: Your a cop?
Saya: Not just a cop. I'm Jade's sister.

Castle: That's the perfect ninja disguise: a white American working as a Yakuza enforcer. He's hiding in plain sight!

Castle: I guess ninjas really do exist.
Saya: No, I was not lying about that. There are no more ninjas Mr. Castle. I am merely a practitioner of the martial arts. But I am very, very good.
Castle: I'll say.

Gates: (after Castle hits her with a ninja star) Ow! Mr. Castle!
Castle: Not boring.
Beckett: Nope. Not at all.
