Keith Sewell: I don't do old women. Nothing over 25.
Calleigh Duquesne: A convicted rapist with standards.
Lieutenant Horatio Caine: MDP2P.
Tim Speedle: Methylenedioxyphenyl-2-propanone. It's not really a recreational drug. It's not really anything
Lieutenant Horatio Caine: Maybe that means he didn't mean to make it. Go with me here for a second, Speed. Now, if you sub in formic acid for nitric acid, you get Ecstasy, don't you?
Tim Speedle: The cook screwed up.
Lieutenant Horatio Caine: Right. But because the pills were white, he figured he could still sell them as X.
Tim Speedle: So he replaces one ingredient along the chemical pathway to try and make something legal.
Lieutenant Horatio Caine: Yes, he did, and ended up making a chemical so powerful, that its fumes could kill human beings.
Tim Speedle: So what are we chasing, the fumes or the pills?
Lieutenant Horatio Caine: We're chasing the cook.
Gregory Kimble: It's not against the law to have those chemicals.
Detective Adell Sevilla: No, it's not. Really brilliant operation Dr. Welmont has going on here. He provides the house, the chemicals and the recipe. He pays off a couple of cooks like you with lux cars. That's peanuts to the guys who sling the pills. Pills so unusual, there's not a law against it, but at the end of the day, he and his partners split about six million bucks.
Gregory Kimble: It's not six million.
Lieutenant Horatio Caine: This is where you say "I don't know any Dr. Welmont."
Detective Adell Sevilla: [answering her phone] Yeah. Right.
Lieutenant Horatio Caine: What do you got?
Detective Adell Sevilla: That was the medical examiner.
Lieutenant Horatio Caine: Mm-hmm.
Detective Adell Sevilla: Just picked up a nineteen year old kid. Overdosed on E.
Lieutenant Horatio Caine: [to Greg] Nineteen years old. Nice going.
Tim Speedle: If we found a pill with Welmont's company stamp on it, why are we going to see the cook again?
Lieutenant Horatio Caine: Because he's weak. Welmont is the target, but Kimble is our ammunition.
Lieutenant Horatio Caine: Here's the irony: had you not been kind enough to provide me with the murder weapon, I would have been stuck with negligent homicide for the neighbor. But as it stands now, I can charge you with murder. And I haven't even gotten to the nineteen year old who ODed.
Dr. James Welmont: So what are you saying?
Lieutenant Horatio Caine: I'm just saying... thanks.
