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.
