Beckett: Murdered Medina just to boost ticket sales? No, that would make this Scooby-Doo... And I'm not Velma.
Castle: Velma, you kidding? You're Daphne... You're hot, smart, not aggressively brainy, but long legs, short skirt...
Castle: Got it.
Ryan: You know what I don't get?
Ryan: Why go to so much trouble to create such an elaborate scam? Fletcher must have spent weeks going through all the prep work.
Beckett: I can give you 50,000 reasons why.
Castle: Yeah, but for con men, it's not just about the money. I mean, for them, it's about the game. The... The thrill they get from pulling a con, it's like a drug high.
Montgomery: [approaching] Con man was on drugs?
Beckett: No, sir. Castle is just giving us psychological insight based on his extensive experience as a fraud.
Beckett: Exactly how many times have you been married, Castle?
Beckett: That's it?
Castle: Isn't that enough? How 'bout you?
Beckett: Me? No. Never been.
Castle: You'd be good at it, you're both controlling and disapproving. You should really try it.
Beckett: I'm not an "if at first you don't succeed" kind of a girl, Castle, when it comes to marriage, I'm more of a "one and done" type.
Castle: Hmm, any serious candidates?
Capt Montgomery: Feds say he's a white male, 25 to 45 years old...
Castle: Could be me.
Capt Montgomery: With a dysfunctional relationship with his mother...
Castle: Still me.
Capt Montgomery: He has a menial, unimportant job...
Beckett: Definitely you.
Castle: Just for that, I base my next book on Esposito.
Castle: I can't believe you got dressed up for this. Tell me again why Ryan and Esposito couldn't come with you?
Beckett: Well, they agreed as a volunteer assistant homicide detective you could really sink your teeth into this avenue of investigation. And they called "not it."
Castle: You know, ever since I've been following you, I've been dreaming of the day that you'd say "let's go to the strip club and get this dirt bag." I just never imagined it would feel like this.
Beckett: Let me know if you need any singles.
Gina: What kind of idiot kills off his best-selling main character?
Castle: Are you asking as my blood-sucking publisher or as my blood-sucking ex-wife?
Gina: Oh, is that what you're doing? Punishing me by killing the golden goose?
Castle: Oh, come on. I may be petty and short-sighted, but I'm not that petty and short-sighted.
