Beckett: Tell me something, Castle. Why did he let you live?
Castle: As punishment, for me ruining his plan. Now he's gonna kill again, all 'cause I couldn't stop him. And I feel so... [shakes his head despairingly]
Beckett: I know the feeling.
Castle: I know you do.
[Beckett puts her hand on his knee. He clasps her hand in his own, his thumb stroking the back of her hand.]

Beckett: The next time you show up at a crime scene without me, I'll show you how my taser works.
Castle: Promise?

Beckett: There is no statute of limitations on murder Mr. Simmons.
Simmons: And here begins what is known as the initial confrontation. During this phase of the interrogation the interrogator may invade the suspect's personal space in order to increase his discomfort. You want to invade my personal space?
Beckett: Look at me. 12 years ago Johanna Beckett lead a big take back the neighborhood campaign in Washington Heights.
Castle: That musta pissed you off.
Simmons: And this would be theme development. Presenting the crime through the eyes of the suspect.
Beckett: Johanna Beckett was murdered, along with two of her colleagues. They were professional hits, carried out on your orders and you had your pet homicide detective John Raglan bury them. Look at her face. Tell me you don't remember her.
Simmons: You know Detective Beckett, I think I do remember her. Bled out in an alley like the trash she was.
Beckett: Mr. Simmons, you'd better watch it��
Simmons: Rich bitch from uptown on safari in the Heights. Somebody should've warned her not to feed or tease the animals.
Beckett: You��
Simmons: If they had, she might not have gotten eaten. From what I hear though, she was pretty tasty.
Beckett: Ah!
Castle: Woah, Beckett!
Beckett: Back off Castle! Remember your old life Vulcan. Savour it. Because I am gonna take it all away.

Beckett: There was, uh, a lawyer named Johanna Beckett, Are you familiar with her? She was murdered in the alley about seven years into your incarceration.
Pulgatti: [Wistfully] You look just like her, you know. When you first walked in here, it was like I was looking at a ghost. The way she talked about you, I should've known you'd become a cop. I sent letters to every lawyer I could find, and your mother was the only one who wrote me back, the only one willing to take a chance on me. She didn't care that I was a thug.
Beckett: [Smiles weakly] All she cared about was the truth

Beckett: This is for the life I saved [pointing at the watch on her left arm which belongs to her father]. And. This is for the life I lost [picking at the ring which belongs to her dead mother].

Beckett: What kind of a name is "Nikki Heat"?
Castle: A cop name.
Beckett: It's a stripper name.
Castle: Well, I told you she was kind of slutty.
Beckett: Change it, Castle.
Castle: Wait. Hang on a second. Think of the titles. "Summer Heat", "Heat Wave", "In Heat"...
Beckett: Change the name!

Beckett: Why is it so important to you that I believe all this stuff about fates and psychics and Santa Claus?
Castle: Because if you don't believe in even the possibility of magic, you'll never ever find it.

Beckett: Yeah, speaking of mentor, I heard that you guys were pretty hard on Conrad last night.
Castle: Hard on him? No, no, it was just a little friendly hazing.
Beckett: To hear him describe it, it sounds like someone was trying to teach him a lesson.
Castle: [Laughs in a forced manner] What? Why would I want to do that?
Beckett: Because you didn't want him to spend time with me?
Castle: That is completely-
Beckett: True?
Castle: [Drops his false humour] Yes. Fine, it's true. I'm jealous. There, I said it. I-I want you all to myself, and to have you spending time with another writer? That upsets me! And if that makes me petty, so be it. Guilty as charged.
Beckett: [Smiles] Actually, I kinda think it's sweet.
Castle: You do?
Beckett: I do. And that's why you don't have to worry about me hanging around with Conrad anymore. From now on I'm a "one writer" girl.

Beckett: You wanted to see me, sir?
Montgomery: Yeah. I just got a call from the mayor's office. Apparently, you have a fan.
Beckett: A fan, sir?
Montgomery: Rick Castle. Seems he's found the main character for his next set of novels: a tough but savvy female detective.
Beckett: ... I'm flattered?
Montgomery: Don't be. He says he has to do research.
Beckett: Oh no.
Montgomery: Oh yes.
Beckett: No way.
Montgomery: Beckett, listen.
Beckett: Sir, he is like a nine-year-old on a sugar rush, totally incapable of taking anything seriously.
Montgomery: But he did help solve this case. And when the mayor's happy, the commissioner's happy. And when the commissioner's happy, I'm happy.
Beckett: How long, sir?
Montgomery: [motioning to his door] It's up to him.
[Beckett turns to find Castle standing in the doorway, smirking]

Beckett: [Showing a photo to two Chinese men she holds at gunpoint] Have you seen this man?
Castle: [In Chinese] My partner is crazy and may start firing at any moment.
[They point]
Beckett: Go. Go! [They run] Semester abroad?
Castle: No. A TV show I used to love.
Beckett: Huh. Nice job.
Castle: Thanks.

Beckett: [To a suspect who is also a street magician] We need to talk to you about Zalman Drake.
Chuck: Abracadabra. [throws smoke bomb at his feet, vanishes]
Beckett: [Opens the lid of the platform he was standing on, pulls him out] Alakazam, jackass.

Beckett:Everybody on the ground now! Back away from the window! Away from the window!
Castle:You're hit.
Beckett:I'm fine. It's not my blood. (into radio) One Lincoln Forty, I have shots fired on 4th and Main. I need backup and an ambulance.
Dispatch:One Lincoln Forty, repeat your last transmission; you were broken. One Lincoln Forty, repeat.
Beckett:Castle?
[Castle shakes his head, Raglan's dead.]

Castle & Beckett: [Simultaneously] She's a taxidermist!
Lanie: It's so cute the way you two do that.
[Castle grins, Beckett rolls her eyes]

Castle: Reading the paper? You are going to lose all of your wired teen hyper texting nano gizmo street cred.
Alexis: I'm a rebel. I kick it old school.

Castle: What?
Beckett: Nothing... it's just I'm so used to seeing you act like a 12-year-old all the time, it's refreshing to see you as a father.
Castle: It makes you want me, right?
Beckett: ...And there's the 12-year-old again.
Castle: Does he look like a killer to you?
Beckett: Everybody looks like a killer to me, Castle. Job requirement
Castle: Do I look like a killer to you?
Beckett: Yes, you kill my patience.
