    • Beckett: So I was a Nebula-9 fan. Big deal.
      Castle: Oh, you were beyond a fan. You dressed up in costume. You.
      Beckett
      : Okay, yes. I was a sci-fi loving, costume wearing geek. And you know what? Not ashamed of it or of Nebula-9. Despite what you think, it was an awesome show.
      Castle: Hmm. I'll tell you what. I'll forgive you your terrible taste, if you (Castle eyes Beckett) try on that Nebula-9 costume for me.
      Beckett: In your dreams.
      Castle: Look at my life. My dreams come true.

    • Beckett: Are you saying...
      Castle: She was killed by a phaser?
      Perlmutter: Well, as much as it pains me, Mr. Castle is marginally correct. She was killed by a high-intensity laser beam.
      Castle: A real sci-fi murder, at a Sci-Fi convention. Just keeps getting better.

    • Castle: Tell me, you guys, do you think my hair is thinning?
      Beckett: You're not losing your hair, Castle.
      Castle: Okay, so if I wake up bald tomorrow, you'll still be attracted to me? (Beckett pauses) Oh, my God. You wouldn't.
      Beckett: I didn't say that.
      Castle: No, but you were thinking it. I can see it in your ...
      Esposito: With that pumpkin head? Dude.

    • Beckett: Just goes to show you, sometimes people aren't what they appear to be.
      Castle: For Alexis' sake, I hope you're right, given what she was wearing.
      Beckett: Castle, she is a full-grown woman.
      Castle: Who, as we speak, is being ogled by thousands of sweaty, lecherous fan boys. It's just so ... wrong.
      Beckett: Can I just point out the fact that the costume that she was wearing is not so different from the one that you are asking me to wear?
      Castle: Don't say that! That ... it's confusing and disturbing.

    • Castle: Let's go back to the e-mails of the crazed Nebula-9 fans. And when I say crazed fans, I'm, I'm not referring to you. You ... are a mega fan.
      Beckett: Nice one coming from the guy with a life-size Boba Fett in his bathroom.
      Castle: Point taken.

    Allusions (2)

    • Castle: Let's make sure that history never forgets the name Enterprise.
      This exact line was spoken by Patrick Stewart as Captain Jean-Luc Picard in Gene Roddenberry's television series Star Trek: The Next Generation (1987-1994), episode Yesterday's Enterprise (1990).

    • Castle: I'm a fan of good sci-fi. StarTrek, Battlestar, that Joss Whedon show, but Nebula 9, nah, nah. It's all phony melodrama and lifeless acting.

      That Joss Whedon show alludes to the television series Firefly (2002-2003) by writer and creator Joss Whedon in which Castle actor Nathan Fillion portrayed the main protagonist, Captain Malcolm "Mal" Reynolds.

      Even the "million square job" gun had a cameo appearance on the work bench of the man who made the phaser gun murder weapon.
