Beckett: Half of the guys are waiting for prints. You don't just jump the line.
Castle: Oh, I think somebody feels threatened.
Beckett: I'm not threatened.
Castle: No, no, I get it. I can call the mayor and you can't.
Beckett: We have procedure. Protocol.
Castle: Yeah, and you always come to a complete stop at a red light and you never fudge your taxes. Tell me something: do you ever have any fun? Let your hair down? Drop your top? A little "cops gone wild"?
Beckett: You do know that I'm wearing a gun?

Beckett: How's the hand?
Castle: Uh, excruciating. How're Ryan and Esposito?
Beckett: Hmm. Mild hypothermia. Wounded pride. Guess which one'll heal first. [She finishes bandaging.] Thank you. For having my back in there.
Castle: Always.
[Sniper shoots Raglan]

Beckett: I hate this case.
Castle: I know, isn't it great?!

Beckett: I'm not running a background check on your daughter's date.
Castle: Oh, come on! She says he's quiet, he keeps to himself, and he lives with his parents. Tell me that doesn't sound like a serial killer to you!

Beckett: I'm sure there's a perfect explanation for all of that.
Castle: There is. They're heeeeerrrrre!

Beckett: If she's so bad, why did you have sex with her this morning?
Castle: Let me tell you something about crazy people. The sex is unbelievable.
Beckett: How shallow are you?
Castle: [soberly] Very.

Beckett: If you keep quoting Jordan, I'm gonna turn the radio way up. [Walks off]
Castle: [To Ryan and Esposito] Jealous.

Beckett: It's Sunday morning. Shouldn't you be slinking home from a scandalous liaison?
Castle: Wouldn't you be jealous if I were?
Beckett: In your dreams.
Castle: Actually, in my dreams, you're never jealous. In my dreams, you just join-- [Beckett shoves bear claw in Castle's mouth]

Beckett: Mrs. Peterson? Detective Kate Beckett, NYPD. I was wondering if I could ask you some questions about Sarah Manning.
Mrs. Peterson: Of course. Please come in.
Beckett: Thank you.
Castle: Richard Castle, just... N.Y.

Beckett: My gut says it's not him. But we still have to look into his alibi.
Castle: Oh, so you don't believe in fate, yet your gut has magical properties. That's cool. Scully.

Beckett: Oh, do you want to see grumpy? How about the cover art for your new novel?
Castle: Nikki Heat cover art? That's only available to... [Beckett starts walking away] oh my God, you subscribed to my website? Wait a minute... are you Castlefreak1212? Castlelover45?
Beckett: You do realize that most people would be creeped by crazy anonymous fans?
Castle: Like you?
Beckett: It was strictly professional curiosity.
Castle: So what did you think of your alter ego Nikki? pretty sweet, right?
Beckett: "Sweet?" She's naked!
Castle: She's not naked! She's holding a gun... strategically.

Beckett: Oh, for God's sake. [referring to Sorenson and Castle] Why don't you both just drop your pants and get it over with?
Castle: I'm game.

Beckett: Okay Castle, I'm here; what's so important?
Castle: Your first clue is: "The Curious Incident of the Dog in the Nighttime".
Beckett: Oh, Jeez, Castle, I haven't even had my coffee yet - (he hands her a cup of coffee) Thank you.
Castle: From the Sherlock Holmes stories, Silver Blaze. Holmes unmasks the murderer because of what didn't happened. The dog didn't bark. That's how he knew: the dog must have known the killer.
Beckett: Okay,yes, I remember the story.
Castle: Then you know that the hardest form of detection is looking for the thing, it isn't there. Byron said that Len was going to verify the hawks. Verify, as in provide proof, which means...
Beckett: He would've had a camera!
Castle: Which we didn't find. And if he was taking pictures...
Beckett: We should be able to figure out what he was up to!

Beckett: Richard Castle, you are under arrest for felony, theft, and obstruction of justice!
Castle: [Smiling] You forgot making you look bad.

Beckett: So where's Esposito?
Ryan: Ha, take a wild guess.
Beckett & Castle: Lanie.
Ryan: Can't believe they still think that none of us know.
Castle: Well, let's let em keep thinking that a while longer. The bubble bursts soon enough.
Beckett: Not if you're in it with the right person.
