Richard Castle: Man, these people need to get a life. Most of these guys, it seems their only companionship is the space alien that talks to them through their microwave.
Kate Beckett: Yeah, well, there's a lot of lonely and confused people out there, but so far none of the letters match the handwriting in our the suspect's notebook.
Richard Castle: Considering what he's capable of, you would think Bracken would have more... formidable enemies.
Kate Beckett: Oh, obviously you never saw the letter that I sent him.
Richard Castle: No, I did actually. I liked the way you uh, dotted the 'I' on "kill" with a little heart. It was a nice touch.
Kate Beckett: Well, I was trying to give it a personal feel.
Joe Flynn: It happened... backstage... right upstairs. They were stealing a moment together which was dangerous because she was Dempsey's girl. As they stared into each other's eyes, Kate's heart quickened.
Kate Beckett: Did you just say "Kate?" Are you picturing the P.I. as you, and me as the gangster's moll?
Joe Flynn: What? No. And I didn't say "Kate." I said, "fate." Fate's heart quickened. I was being poetic. God.
Richard Castle: Hey, do you know what Lanie and Esposito were fighting about?
Kate Beckett: Everything. They both want to be together, but neither of them wants to admit to it.
Richard Castle: Ugh! Why do people do that to themselves?
Kate Beckett: Maybe they just don't see it.
Richard Castle: How could they not? It's so obvious.
