Castle, Season 5

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 try on that Nebula 9 costume for me.

Beckett:
In your dreams.

Castle:
Look at my life. My dreams come true.
