  • Wow, watch Dexter much?

    "Fair"
    By thefanof, Sep 09, 2011
    In 2009 Dexter had a season long arc involving a mass murderer known as "The Trinity Killer." Here in tonight's Castle they had "The Triple Killer." Both men killed in threes. While it is clear that they ripped the storyline from the popular Showtime series, I still have to say that this was a thoroughly entertaining episode of ABC's only real cop show worth watching. Castle was on his game comedically, but thankfully they also had some serious moments in the episode to put over the vitality of this murderer.

    Good episode, definitely turned me into a Castle fan with this one.moreless

  • Great story line, super suspenseful but a bit to much going on

    "Superb"
    By LauraPeterson45, Feb 26, 2011
    First off i have to stay that i thought this episode was great, but i think they should have done it in a two episode format like they did with "Tick, tick, tick...." and "boom". Whoever the guest actor was who played Gates was superb. He nailed the super confident, smug homicidal charm of his character. Stana Katic was brilliant too. i really felt her rage at not having enough evidence to lock him up. She also held her own in the interrogation scenes. Also the twist at the end was amazing. I can usually guess what's going to happen but this one kept me guessing!

    Just a heads up things might get a little spoilery from here on out so stop reading if you want. I just thought there were so many elements to this story that could have used some more time. The last five minutes was basically another episode within itself. The revelation about the true killer and Castle's ordeal felt a bit rushed to me. I felt they really could have expanded on that or done more with Castle's brush with death. I know 3xk will probably reappear later in the season but i want more of him now!moreless

  • Best episode since the opener! Loved the intensity and the thought that it could be over then, POW! The dark episodes are needed occasionally to take it away from the light fun eps (that I also love) but this sort I can rewatch and rewatch.moreless

    I love the dark episodes so this was right up my street. The way it started with the first victim alive was a new thing for Castle and I really liked that. Montgomery being used more for these episodes is a given and always such a great performance that adds to the intensity. I wish Beckett had clued onto the first victims MO as she is the cop, but I know that Castle has to have his theories, so can let that go. Acting as always was fantastic and liked the fact that even the loft scenes with the Castle's was more intense rather than taking us away from the episode. The case was just brilliant from start to end with the twists and turns and the interrogations were realistic and you felt Beckett's frustration, (Stana is just amazing) And yes, it was left open at the end for more! (Cannot wait) Kudos to the writing/directing.moreless

  • Castle at its best!

    Castle has been one of the few shows that compell me to turn the tv on at night.
    Yeah, with an awesome cast, interesting stories, no doubt this one is one of the most viewed show every week.

    In this episode, we have a very intriguing story and an unexpected twist at the end.

    Dunno about you guys but I thought Kate's reaction near the rescue part was a little bit over the top. I mean, it sounded kinda like "I need to say something that will show to the viewers that although it seems I'm extremely annoyed by you.. I really, really like you.."
    I believe some gestures and very emotional look would've sufficed.. but oh well, it was a great episode nonetheless..

    Cheers!moreless

  • A really sad episode.

    "Perfect"
    By yarnqueen, Feb 26, 2011
    This Castle is way up there with my favorites. It is the flip side, in a way, of "Boom". Instead of Castle rushing to Beckett's rescue and terrified that he may have been too late, is is Beckett rushing to his, equally afraid that she is too late, and it is she holding his hand in the aftermath as they together realize that they have lost their man and that they may never get the chance to catch him again.
    I LOVED this episode because it shows that Castle can also be vulnerable, also care more about the results of their investigation than about his ego: he realizes that this killer will (not MAY)strike again and that it may be his fault.moreless

  • TRIVIA (2)

    ADD TRIVIA

    • In this episode Castle reveals that one of his previous novels was titled "When It Comes to Slaughter".

    • Goof: Near the end of the episode when Jerry picks up Castle's cell phone, the phone clearly shows a picture of Castle's mother and says "Home - Mobile". Martha is shown speaking on the home landline in the next shot, so Castle's display should indicate a home not a mobile number and he couldn't have known it was his mother calling from his apartment as opposed to Alexis.

    ADD QUOTES

    • Castle: Tell me you've arrested Gates.
      Beckett: Not even close. I mean, I don't know how, Castle, but he killed Kim Foster, and he's gonna do it again.
      Castle: There's been no developments? Usually you call me with news. ... You called to seek my counsel.
      Beckett: I wouldn't say it exactly like that.
      Castle: No, no, no. You were hoping I had some wild theory, some sort of penetrating insight that would lead us to a breakthrough.
      Beckett: Well... do you?
      Castle: ... Nah! I got nothin'.
      Beckett: I just need some piece of evidence. I mean, someone that he talked to, anything.
      Castle: What if Gates confided in Jerry about the previous murders?
      Beckett: Yeah, well, Jerry's not gonna talk to us. He got beaten up in the prison yard this morning, and he thinks that Gates had something to do with it.
      Castle: Sounds like Gates is afraid of what Jerry Tyson knows.

    • Beckett: Tell me something Castle, why did he let you live? Castle: To punish me. Make me pay for ruining his plan. Now he's going to kill again all because I couldn't stop him and I feel so… Beckett: I know the feeling. Castle: I know you do.

    • Beckett (she kicks in the door): Castle??? Castle: It's clear, he's gone. I'm fine, Ryan needs an ambulance. Ryan: (mumbling from the floor) No, I don't. Esposito: Hey, what the hell happened here? Beckett: I'm so glad that you're ok. Castle: He's the triple killer, he set Gates up to be a copycat. Beckett: I know, I did the math when you and Ryan didn't come back from talking to Jerry. Castle: How did you know to come here? Beckett: Your mom called; she said that you told her you loved her and she figured that something must be terribly wrong. Castle: I figured she might; good girl.

    • Capt. Montgomery: Feds say he's a white male 25 to 45 years old. Castle:(whispers to Beckett) It could be me. Capt. Montgomery: With a dysfunctional relationship with his mother. Castle: (whispering to Beckett) Still me. Capt. Montgomery: He has a menial unimportant job. Beckett: Definitively you. Castle: Just for that I'm basing my next book on Esposito.
