David Hodges: [Walks in as Grissom is cleaning out his office] Okay. So this is really real. Fine. So, as your friend and colleague I feel that it is my obligation to inform you what a colossal mistake you're making. Grissom:
Gil Grissom: Hodges...
David Hodges: Guys like us just don't get to hang it up. This job is who we are. We are the thin blue line between order and chaos. You take yourself out of the equation, who knows what's gonna happen. That's the Butterfly Effect. You taught me that. The bad guys will win more if we don't have you. Who is Watson without Sherlock Holmes?
Gil Grissom: Watson was a genius in his own right... It's the right time for me to go.
David Hodges: Okay.
Gil Grissom: A penny for your thoughts?
Dr. Raymond Langston: [Pointing up to where the Tom Donover was sitting] He was sitting right there. He was looking at me, I was looking at him. All I saw was another student.
Gil Grissom: That's all I saw.
Dr. Raymond Langston: I guess I'm tired of getting fooled.
Gil Grissom: People lie, Professor. The only thing that we can count on is the evidence.
Dr. Raymond Langston: Thank you for letting me help. It was...
Dr. Raymond Langston: Well, it was something that I really needed to do.
[Starts to walk away]
Gil Grissom: Hey
[Langston turns around]
Gil Grissom: I don't know if you'd have any interest, but we have a job position open in our lab.
Dr. Raymond Langston: You're serious?
Dr. Raymond Langston: I can't imagine myself as a cop.
Gil Grissom: We're not cops. We come from a wide variety of backgrounds. You're a medical doctor. You're totally qualified. It's an entry level position. The hours are terrible, the pay is bad.
Dr. Raymond Langston: But money's not exactly the object, is it?
Gil Grissom: I think that you'd be a great help to CSI and you might really enjoy it.
Dr. Raymond Langston: I'll think on it.
Nathan Haskell: Professor Langston, how good to see you. What brings you here?
Dr. Raymond Langston: I came to gloat.
[Sets photos on the table]
Dr. Raymond Langston: Please, come in, Nate... We got these from a videotape of one of your kills. It's hard to believe, isn't it? Now, in all fairness, you did say that only dummies take souvenirs and Gerald Toliver was a pretty dumb guy. Maybe that's why Tom Donover killed him. You know, I've been thinking that maybe, that's the reason Tom Donover decided to follow in your footsteps, and carry on your work...
Dr. Raymond Langston: Anyway, none of that really matters now, because
[starts laying out more photos]
Dr. Raymond Langston: as you can see, we found your house in Lake Mead and we have Tom and the girl, she's alive.
Nathan Haskell: Then what do you need me for?
Dr. Raymond Langston: Closure. You once told me you've been thinking about it a lot, well I've been thinking about it, too. I need you to tell us where the girls' bodies are buried, Nate.
Nathan Haskell: I see. So you're working with that cop now?
Dr. Raymond Langston: We're gonna find them eventually, you know that. We'll dig, we'll dredge the lake, we'll tear that house of yours down to the studs if we have to. Now, why don't you save us the trouble? Tell us what we need to know. Look, maybe I could get something out of it for you.
Nathan Haskell: Like what? You gonna reduce two consecutive life terms down to one?
Dr. Raymond Langston: Like maybe I could guarantee that this isn't the last conversation that you'll have with someone who isn't shoving your food through a hole in the door. I promise you, Nate, you don't tell me what I need to know and the only person who will hear the sound of your voice again is gonna be you.
Nathan Haskell: [Thinks] You follow the fence in the back yard.
Dr. Raymond Langston: To where?
Nathan Haskell: [Realizes Langston is bluffing and doesn't know where the house is or where the girl is] To where, what? There is no fence in the backyard... You thought you could make me slip up again and give you somethin' you want. You thought that you could get inside of my head? A person has to do what I've done to understand me. You have no idea what I've started. I'm a teacher, too. My students are everywhere, they're out there. I'll cut them free, I'm spreading the word, by the time you find them it'll be too late and there will just be more blood on your hands.
Dr. Raymond Langston: Get him out of here.
Nathan Haskell: [Cops are dragging Nate out of the interview room] She's already dead.
Dr. Raymond Langston: Get him out of here!
