CSI: Crime Scene Investigation

Sara: If Gibbons had that severe a reaction to peanut shells, imagine what eating peanut butter would do to him. Warrick: Yeah, that's more than just messing with a guy's head. Sara: That's murder.

Sara: He wore a medic alert bracelet. Everyone hated him, and everyone knew how to kill him.

Brass: Chris Gibbons, UNLV grad student. The jury's been sequestered two and a half weeks on a murder trial. Grissom: Twelve strangers ... stuck in a room with no exit. It's like Sartre said: "Hell is other people."

Greg: I'm not the allergy ace. I'm trying to get out in the field and you're multitasking me in the lab. Catherine: Greg, I'm the one who actually put you on a case not just talked about it. Greg: You're also the one who took me off the case. (Greg gets up and walks away from her over to a table) Catherine: You know what? You started and you gave me six strong innings, and I brought in the closer. What's wrong with that? Greg: So what am I? Fish or fowl? Catherine: Fish. That's a good place to start.

Jervis: I lost my temper. Catherine: You sure it's lost?

(Looking at a hair) Grissom: There's no tag cells, and she's not a natural blonde, and it looks synthetic. Brass: Hey, this is Vegas baby.

Greg: No she didn't. Sara: Greg, she told Warrick she put peanut butter in the chili. Greg: I don't care if Mr. Peanut was taking a bath in the vic's lunch. It's not what killed him.

Nick: We never answered the question why she just woke up one morning and walked away from the rest of her life. Grissom: It happens. And that's what the evidence was telling us. Nick: Well, that's what the physical evidence was telling us. We should have dug deeper. You can't just ignore the human element, Grissom. Grissom: I agree, Nick. But when you start to have feelings for the people involved, you risk your objectivity. Nick: So what? You know, I'm always getting criticized for empathizing with the victims and their families, but that's who I am. That's how I do my job. And as far as the promotion goes, it's all good, man. I can live without it. I'm not you. Grissom: Good. We certainly don't need another me around here.
