- Richard Castle: Listen, if you're not scared... just say it?
- Kate Beckett: No.
- Richard Castle: Come on. You know you want to.
- Kate Beckett: I don't wanna say it, Castle.
- Richard Castle: For me. Please?
- Kate Beckett: I ain't afraid of no ghosts.
- [an instrumental snippet of the "Ghostbusters" song plays]
- Richard Castle: So, if Barry's not our guy, I think it's time we revisit the possibility that our killer's...
- Kate Beckett: f you say "ghost," I'm sending you home.
- Richard Castle: Apparition American.
- Richard Castle: I don't know, but I think it's time we found out.
- Kate Beckett: Knock yourself out, Castle.
- Richard Castle: You're not coming?
- Kate Beckett: No, I've got a murder to solve.
- Kevin Ryan: I'll go.
- [Beckett stares at him]
- Richard Castle: Ooh. That's a look.
- Kevin Ryan: Yeah.
- Richard Castle: I get these a lot. Just start walking. Faster.
- Lanie Parish: His throat was slit, almost from ear to ear. Jugular, superior thyroid, common carotid, left and right. You name it, it's been severed.
- Richard Castle: Well, that explains all the blood.
- Lanie Parish: Here's what I can't explain: depth and nature of the wound tell me that the killer got up close and personal.
- Kate Beckett: So where are the footprints?
- Lanie Parish: Not just that. Look at the blood spatter. You cut all those arteries, and the spray is gonna come fast and it's gonna come strong.
- Richard Castle: I'll say. It went everywhere.
- Kate Beckett: But it shouldn't have. Some of it should have landed on the killer.
- Richard Castle: Yet, every drop of it landed on the floor. The spray is completely unobstructed.
- Lanie Parish: Exactly. It doesn't make sense.
- Richard Castle: Unless... the blood passed right through the killer.
- Lanie Parish: Are you saying a ghost did this?
- Kate Beckett: Please don't encourage him.
- Richard Castle: I'm saying, maybe Mr. Sinclair finally met a wraith he couldn't wrangle
- Pete Benton: Matt had a terrible temper. He was convinced Melanie was cheating on him.
- Kate Beckett: Was she?
- Pete Benton: Wouldn't surprise me if she was. Matt thought it was somebody at work.
- [cut to the precinct]
- Kevin Ryan: It wasn't someone Melanie worked with. I just tracked down George Banner, Melanie's manager at Fly-wide Travel from 20 years ago. He said Melanie had two co-workers. Both guys.
- Richard Castle: Uh-huh.
- Kevin Ryan: Married.
- Richard Castle: Still.
- Kevin Ryan: To each other.
- Richard Castle: Oh.
- Richard Castle: [arriving at the crime scene] The "Ghost Wranglers" are here? Okay, that's *why* I love these guys. Body's not even cold, they're already tracking down the ghost.
- Kate Beckett: Why doesn't it surprise me that you actually watch that ridiculous show?
- Richard Castle: Ridiculously awesome! Jack Sinclair is hands-down America's most accomplished ghost hunter.
- Kate Beckett: Oh... Castle... Jack Sinclair is the name of our victim.
- Richard Castle: And the hunter becomes the hunted...
- [while watching Night of the Living Dead on TV, Castle pulls Alexis in front of him]
- Alexis Castle: Dad, are you using me as a shield against flesh-eating zombies?
- Richard Castle: No, no, I just wanted you to have a better view.
- Javier Esposito: Yo, I just say Ryan downstairs. I can't believe you let him go chasing ghosts with Castle.
- Kate Beckett: Yeah. Maybe Shaggy'll keep Scooby out of trouble.
- Kate Beckett: You know what? No worries. It's on my way home.
- Javier Esposito, Kevin Ryan: You sure?
- Kate Beckett: That I don't wanna be the one to blame for ruining Lanie's night out? Oh, yeah. I am sure.
- Kate Beckett: You know what, I am just following the evidence, wherever it may lead. And as a cop, I'm going to consider every possible worldly explanation.
- Richard Castle: Mm-hmm. And what if there is none?
- Kate Beckett: Well, then I'm open to the alternative.
- Richard Castle: [laughs] You? Skepticus Maximus?
- [last lines]
- Richard Castle: I could promise you this. If two people believe in something, really believe, anything, even the impossible, is possible.
- Alexis Castle: [reaching for the remote] Even flesh-eating zombies?
- Richard Castle: Oh, especially flesh-eating zombies. Now, where were we?
- Alexis Castle: Yeah, right there.
