- [last lines]
- Kate Beckett: And if you tell anyone what I'm about to say, there's gonna be another shooting, but... I've gotten used to you pulling my pigtails... I have a hard job, Castle, and having you around makes it... a little more fun.
- Richard Castle: [pause] Your secret's safe with me.
- [first lines]
- Javier Esposito: Meet the late Jack Coonan.
- Kate Beckett: Why is that name familiar?
- Kevin Ryan: 'Cause it probably crossed all our desks a dozen times in the last few years. Aggravated assault, ADW, arson.
- Javier Esposito: Coonan had a heavy rep. Word is he's an enforcer for the Westies.
- Lanie Parish: Okay, remind me. Who are the Westies, again?
- Richard Castle: Irish mafia out of Hell's Kitchen.
- Kate Beckett: They deal in cargo theft, counterfeiting, extortion.
- Kevin Ryan: And public urination on St. Patrick's Day.
- Kate Beckett: It wasn't your fault, you know.
- Richard Castle: [long pause] I overstepped. I came down here to say that I'm sorry. And that I'm through... I can't shadow you anymore. If it wasn't for me...
- Kate Beckett: If it wasn't for you, I would have never found my mom's killer. And someday soon, I'm gonna find the sons of bitches who had Coonan kill her. And I'd like you around when I do.
- Dick Coonan: Did, uh...
- [clears throat]
- Dick Coonan: Did my brother suffer?
- Kate Beckett: Yes.
- Dick Coonan: Thank you for your honesty. I guess you could have lied to me.
- Kate Beckett: No, I couldn't. I've been on your side of the table and when I was, what I needed most was the truth.
- Dr. Clark Murray: Note the rectangular bruising around these wounds here and here...
- Kate Beckett: Mm-hmm.
- Dr. Clark Murray: ...caused by the hilt of of the knife striking with force enough to compress the skin.
- Kate Beckett: And as a result, the injuries penetrate deeper than the actual length of the blade.
- Dr. Clark Murray: He's also honed the blade so fine it's brittle enough for bits to break when it strikes bone, which is why slivers of blade were found inside both of his victims... We now know those slivers come... from the same murder weapon.
- Kate Beckett: Wait. Two victims? How many people has he killed?
- Lanie Parish: Five... that we know of.
- Kate Beckett: So we're looking at a serial.
- Dr. Clark Murray: Well, yes and no. We believe we're dealing with a professional. Someone with extensive military training.
- Kate Beckett: A contract killer.
- Dr. Clark Murray: I used tomographic reconstruction of Coonan's wounds to generate a 3-D model of the blade used. It's a Special Operations Group knife, the kind favored by Special Forces in Gulf War I. He kills with a single blow, using these other wounds to camouflage the skill with which the initial stroke was delivered... The very same method and the very same weapon that the killer employed... ten years ago.
- Kate Beckett: [after long pause] Lanie...
- Lanie Parish: I'm so sorry.
- Dr. Clark Murray: Detective Beckett... there is no doubt in my mind... that Jack Coonan was killed by the same man who murdered your mother.
- Kate Beckett: I let her down.
- Richard Castle: No, you didn't.
- Kate Beckett: Rathborne's in the wind. Dick Coonan's about to walk.
- [pause]
- Kate Beckett: I missed something.
- Richard Castle: Could have been me. Rathborne could've checked the routing number, realized the money was coming from... *my* account, not Dick's. I was arrogant.
- Kate Beckett: I didn't think you were arrogant, Castle. I thought what you did was sweet. And I will pay you back as...
- Richard Castle: Negative, ghostwriter. Small price to pay for a shot at your mother's killer.
- Kate Beckett: Castle, these Westies can be pretty rough.
- [chambers a bullet in her gun]
- Kate Beckett: So you sure you don't wanna stay in the car?
- Richard Castle: No way.
- Kate Beckett: Okay. Keep your mouth shut and... try to butch up a little.
- [Beckett and Castle in the morgue with what they think is the murder weapon]
- Lanie Parish: That's not it.
- Kate Beckett: You didn't even look.
- Lanie Parish: Sure I did. It's a stiletto, four-inch Damascus blade, and it's way too small to make these wounds.
- Richard Castle: Well, maybe he used a different knife.
- Lanie Parish: Just how tall is this Trucho?
- Kate Beckett: He's, um... 5'6".
- Richard Castle: Standing on his toes.
- Lanie Parish: Then he's not your guy. Thrust angle on these wounds indicate Coonan's killer was over six-foot.
- Richard Castle: Well, maybe instead of using a stiletto, he was wearing stilettos.
- Richard Castle: No one even knows what Rathborne looks like.
- Officer Clayton Lee: Well, he shouldn't be too hard to spot.
- Kevin Ryan: Yeah, he'll be the one who's trying to kill ya.
