Roy Montgomery: [profiling 3XK] The feds say he's a white male, twenty-five to forty-five years old.
Richard Castle: [quietly, to Beckett] Could be me.
Roy Montgomery: With a dysfunctional relationship with his mother.
Richard Castle: Still me.
Roy Montgomery: He has a menial, unimportant job.
Kate Beckett: Definitely you.
Richard Castle: Just for that, I base my next book on Esposito.
Jerry Tyson: It must eat you alive knowing that you came so close to catching me. But this is a winner take all type of game.
Richard Castle: Oh, Jerry, shooting? It's not your style.
Jerry Tyson: Oh, you really don't know me at all, do you?
Richard Castle: Oh, it's not complicated. You were raised by a single mother. She was blonde. Oh, she was beautiful, but... she never wanted you. When you were, what, twelve I'm guessing, she died suddenly, let's say... drug overdose. You go into foster care, the bad kind. You have so much hate... so much hate towards your mother for abandoning you that you kill these women to get back at her. But you leave them looking peaceful because as much as you hated your mother, you loved your mother. Am I getting warm?
Jerry Tyson: You're drawn to death. You like to be around it, because it thrills you. Now where does that come from? Your own suppressed impulses. How close to death do you wanna get?
Kate Beckett: I see domestic complaints by the double digits...
Richard Castle: Filed by his wife.
Kevin Ryan: Ex-wife. They were divorced last month after being married for four years.
Richard Castle: So in a way, he did just get out of prison.
Lanie Parish: [Beckett and Castle enter the morgue] That was quick.
Richard Castle: 911 has that effect on her.
Kate Beckett: Castle, do you have a theory you'd like to share with the class?
Kate Beckett: [seeing Castle's expression as he looks at the victim] What?
Richard Castle: Uh... it's nothing.
Kate Beckett: No, what?
Richard Castle: Well, she just... looks so peaceful.
Alexis Castle: What about Ashley? I mean, shouldn't I tell him?
Martha Rodgers: Darling, in matters of the heart, it's best not to overthink things.
Richard Castle: That's your advice, mother? With your track record? What chasm of doom has she led you to by way of her tips on romance?
Martha Rodgers: As it happens, we were discussing secret admirer etiquette.
Richard Castle: You have a secret admirer?
Alexis Castle: I always thought it was silly, but now I'm kind of intrigued.
Richard Castle: [Alexis is trying to deduce the identity of her secret admirer] What are you doing?
Alexis Castle: Narrowing down suspects.
Richard Castle: No, you can't do that. No, you... no, that'll ruin the secret. No, it's like a mystery novel. You don't just go to the last page, do you?
Alexis Castle: Yes.
Richard Castle: You do?
[Alexis shrugs innocently]
Richard Castle: Well, you shouldn't. It's not... you can't... the... the... joy doesn't come in knowing who did it. The joy comes in the journey, and allowing the ending to... blossom, like some magnificent Himalayan blue poppy.
Alexis Castle: Okay. Okay, I'll let him stay secret.
Richard Castle: Mark my words. You'll thank me.
Kate Beckett: What'd you find?
Lanie Parish: I pulled all the files on all his past murders, just like you asked.
Richard Castle: I... I believe that was my idea.
Lanie Parish: Yeah, but I only listen when it comes from her.
Kate Beckett: Anyway, you were saying?
Lanie Parish: He choked them using a three-strand twist, quarter-inch rope. Based on the fibers found embedded in the skin, we know that the rope is green and white nylon.
Richard Castle: I don't remember that.
Lanie Parish: Those details were never made public. Now check this out.
[Lanie holds an evidence photo next to the victim's neck for comparison]
Richard Castle: The marks are identical.
Lanie Parish: I found the exact same green and white fibers.
Kate Beckett: It is him. The Triple Killer is back.
Richard Castle: Hey.
Kate Beckett: Hey. There's no news from CSU on the name tag. Not that I was expecting any.
Richard Castle: Makes you wonder why he didn't pull that whole gas leak routine on Linda Russo.
Kate Beckett: I know why. The answer's in here.
Richard Castle: A transcript?
Kate Beckett: From four years ago. I took a look at calls made to the Triple Killer tip line, and this one stood out for me. It's from May 21st, 2006, which was a week after the sixth murder. A woman called and left a message, but she was too afraid to leave her name. But she did mention that she lived at 24th and 10th.
Richard Castle: Same corner as Linda Russo.
Kate Beckett: She was riding an elevator with a cable repair man who so creeped her out that she got off a floor early just to get away from him.
Richard Castle: Yeah, but cable guy and creepy, that's a job requirement.
Kate Beckett: Except he wasn't a cable guy. She said he wasn't carrying the right tools.
Richard Castle: And working for a cable company, Linda Russo would know that.
Kate Beckett: Which is why I took a look at Linda Russo's phone records from four years ago. She's the one who made the call to that tip line.
Richard Castle: So Linda Russo was special.
Kate Beckett: When she got off a floor early, he knew that she made him, so he dropped out of sight.
Richard Castle: Which also explains why he attacked her outside. He knew there was no way she'd let him into her apartment.
Kate Beckett: Linda Russo saw his face, and he came back four years later. That's a special kind of ruthlessness.
Richard Castle: [reading a note Beckett scribbles down] "Jelly Tyson"?
Kate Beckett: It's Jerry, Castle. When Gates got released, he gave all his stuff to Jerry Tyson, a fellow inmate. So if the two of them were friends, Jerry might be able to tell us where we can find Gates.
[as Beckett leaves, Castle pauses to correct the note]
Richard Castle: Now it's Jerry.
Kate Beckett: [discussing Gates] He wants the search warrant to get a peek at our cards.
Richard Castle: How is that giving him a peek?
Roy Montgomery: The warrant lists ropes, uniforms, and other personal effects belonging to Kim Foster, Linda Russo, and the other six Triple Killer victims. By looking at the warrant, he can gauge where we are in our investigation.
Richard Castle: That's not giving him a peek, that's showing him our whole hand. He'll know we think he's the Triple Killer.
Kate Beckett: He already knows.
Javier Esposito: [entering] Yo. Empire Prop confirmed that Gates works in their warehouse and had access to those tags. He clocked out at 7:02 the night of Kim Foster's murder. Now, Empire is in Lincoln Square, which means he had enough time to get to her apartment and push the intercom button by 7:35.
Roy Montgomery: Show him the warrant. Odds are he will lawyer up, but try to stop him.
Richard Castle: [Beckett leaves] How's she supposed to do that?
Roy Montgomery: [grimly] I don't think she can.
Martha Rodgers: [Alexis is planning to meet her secret admirer] Richard, darling, she's right. You are being utterly irrational. It's like when I was doing "Who's Afraid of Virginia Woolf?" and I thought my understudy was trying to poison me.
Richard Castle: Oh, yeah. The daily blood tests I paid for. Wait, she did poison you. The Swiss chocolate she gave you was a laxative.
Martha Rodgers: Eh, eh. It added a certain urgency to my performance. But the point is you indulged my paranoia, so therefore I am going to be in the park, five o'clock, at a discreet distance to make sure that Alexis' secret admirer is not an ax murderer.
Richard Castle: Thank you.
Richard Castle: Tell me you've arrested Gates.
Kate Beckett: Not even close. I mean, I don't know how, Castle, but he killed Kim Foster, and he's gonna do it again.
Richard Castle: There's been no developments? Usually you call me with news.
[realization dawns on him]
Richard Castle: You called to seek my counsel.
Kate Beckett: [reluctant to admit he's right] I wouldn't say it exactly like that.
Richard Castle: No, no, no. You are hoping I had some... wild theory. Some sort of penetrating insight that would lead us to a breakthrough.
Kate Beckett: Well? Do you?
[pause, as Castle tries to come up with something]
Richard Castle: No, I got nothing.
Kevin Ryan: You were right about Gates. He did try to go after Donna, but she's okay.
Jerry Tyson: And Gates?
Kevin Ryan: He confessed. It's all over.
Jerry Tyson: Thank god.
Richard Castle: Aren't you gonna ask what happened? To your girlfriend, Donna. You didn't ask about her. You just asked about Gates. Doesn't make any sense, unless...
[realization dawns on him]
Richard Castle: ...she was supposed to die.
Jerry Tyson: I... I don't know what you...
Richard Castle: McCardle didn't get the money for the surgery until after you got out of prison. He's removing all evidence he was even there. It was him all along. He's the real Triple Killer.
[Ryan moves to draw his weapon, but Tyson knocks him out, picks up his weapon, and holds it on Castle]
Jerry Tyson: Guilty as charged.
Richard Castle: That story about Gates getting arrested, that was your story, wasn't it? You were afraid you were gonna get caught, so you hid in prison.
Jerry Tyson: Too bad you didn't figure that out sooner.
Richard Castle: Too bad you didn't leave sooner. Cops will be here any minute.
Jerry Tyson: Looks like Detective Ryan called the precinct just before he got here. There won't be anybody missing me for a while. But by the time they do, I'll be long gone.
Richard Castle: You won't get far. They already have your name, know your face.
Jerry Tyson: I'll change those. I've done that before. That's part of the fun of it.
Kate Beckett: I'm so glad that you're okay.
Richard Castle: He's the Triple Killer. He set Gates up to be a copycat.
Kate Beckett: I know. I did the math when you and Ryan didn't come back from talking to Jerry.
Richard Castle: How did you know to come here?
Kate Beckett: Your mom called. She said that you told her that you loved her, and she figured something must be terribly wrong.
Richard Castle: I figured she might. Good girl.
Kate Beckett: Tell me something, Castle. Why did he let you live?
Richard Castle: To punish me. To make me pay for ruining his plan. Now he's gonna kill again all because I couldn't stop him. And I feel so...
Kate Beckett: [supportively putting her hand on his knee] I know the feeling.
Richard Castle: [taking her hand in his] I know you do.
