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: They started up about eight weeks ago, according to those e-mails. He met her after one of his... book signings and he asked her out for coffee and that was a... It was just a couple of weeks after we started seeing each other.
Lanie Parish: Oh, sweetie.
Kate Beckett: He told her that needed to keep it a secret, because he was with someone else... And then when he tried to break it off about a week ago, she threatened to go and tell his girlfriend. He offered to come over to her apartment to talk things through. And that was the night of the murder.
Lanie Parish: He had motive... What did Castle say when you talked to him?
Kate Beckett: He said that the e-mails were faked. He said he never wrote that story and that he was being framed...
Kate Beckett: You should have seen him, Lanie. He looked like a little boy, he was so scared... I know him, Lanie... He is... an immature, egotistical... self-centered jackass sometimes, but he's not this.
Kate Beckett: Castle?
Richard Castle: Hmm.
Kate Beckett: Should I be worried about your commitment to our engagement?
Richard Castle: No. why?
Kate Beckett: 'Cause it says right here that you're getting back together with your ex-wife.
Richard Castle: What?
Kate Beckett: Right here, page six.
Richard Castle: "Castle caught cuddling with ex-wife publisher". No, no. This was a business lunch. We were discussing Heat and Storm books.
Kate Beckett: Oh, so, um, you weren't...
Kate Beckett: "gazing lovingly into her eyes"?
Richard Castle: She had spinach in her teeth! That's just... Okay. I don't... See, this wouldn't happen if you just let me announce our engagement.
Kate Beckett: We already talked about this. Everyone that's important to us already knows.
Richard Castle: Yes, and just because I'm a public figure doesn't mean you need to be one, too. I know.
Kate Beckett: Exactly.
Richard Castle: Well, so long as you don't mind this sort of thing happening.
Kate Beckett: I don't. 'Cause it's not true. And it only gives me more material to torture you with.
Richard Castle: Mmm, and the student becomes the master.
