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.
Kate Beckett: Who put you up to this, Bobby? Who gave you that backpack?
Bobby Lopez: I don't... I don't know. I don't remember.
Kate Beckett: You don't remember? How do you not remember?
Bobby Lopez: I was in shock. A bomb went off, everyone was running and screaming...
Kate Beckett: Oh, oh. Okay, okay. So you remember what happened after the bomb went off but not before?
Bobby Lopez: It must have been one of those traumatic amnesia things.
Kate Beckett: Bobby!... Don't lie to me.
Bobby Lopez: I'm telling you, it was all a big blank. It was the trauma.
Kate Beckett: It was not the trauma. You don't get to use that excuse.
Bobby Lopez: I swear! I don't remember.
Kate Beckett: The *hell* you don't remember! Do you want to know trauma? I was shot in the chest. And I remember every *second* of it... And so do you.
Richard Castle: [watching in the observation room] All this time... You remembered?
Kate Beckett: I'm telling you, something happened, something changed. It's been weird between us lately.
Lanie Parish: Lately? Kate, it's been weird for four years.
Kate Beckett: No. This is different. He's different. It's like he's pulling away.
Lanie Parish: Well, can you blame him? He's probably tired of waiting.
Kate Beckett: Waiting for what?
Lanie Parish: What do you think? The guy is crazy about you, snd despite your little act, you're crazy about him.
Lanie Parish: Oh, what? Was that supposed to be some big secret?
Kate Beckett: [with mixed indignation and defensiveness] Yes!
Kate Beckett: [deflating, being honest with herself] No. Do you think he knows?
Lanie Parish: You remember how he used to be? Girl on either arm? You really don't see that guy too much anymore. Why do you think that is? He's waiting for you.
Kate Beckett: Yeah, but, Lanie...
Lanie Parish: I know. You're dealing with stuff. But you cannot ask him to wait forever... Unless, of course, you're okay with him pulling away.
Kate Beckett: What if it doesn't work? What if it ends up like you and Javi?
Lanie Parish: Well, at least we gave it a shot. And so it didn't work out. So what? Now we can move on. Give or take the occasional booty call.
Kate Beckett: I just, I don't wanna lose what we have, you know?
Lanie Parish: Girl, please. What exactly do you have? Really?
Kate Beckett: A friendship?
Lanie Parish: No. What you and I have, is a friendship. What you and Castle have is a holding pattern. How long can you circle before the fuel runs out?
