- Gil Grissom: [to Ethan] Let me tell you something, Humbert. You're twice the age of these kids, and half of them couldn't find their own ass with a map. You prey on innocent children, concocting God-knows-what from God-knows-where, selling Russian Roulette in a bottle and you think we came all the way out here to bust you for possession, you dumb punk? I'm gonna get you for murder. Cool?
- Gil Grissom: I was flying to a seminar in New Hampshire a couple of summers ago. I was sitting in the plane next to a Philosophy Professor from Harvard. He told me this story about how every morning he takes a leak right after his three-hour philosophy class. He flushed the toilet, there'd be this tiny brown spider fighting for its life against the swirling water. He came back the next day, flush. Same spider, clawing its way back from oblivion. A week goes by, he decides to liberate the spider. Grabs a paper towel, scoops him up and sets him on the floor in the corner of the stall. Comes back the next day, and what do you think happened to the spider?
- Warrick Brown: Dead.
- Gil Grissom: On his back, eight legs in the air. Why? Because one life imposed itself on another. Right then I realized where we stand. I understood our role. We don't impose our will. We don't impose our hopes on the evidence.
- Nick Stokes: It's our job to know how. You heard Grissom: the more 'how' the less 'why'. The less the 'how' the more the 'why'.
- Catherine Willows: Hey, Nick. Grissom's not always right. Do yourself a favor ; think for yourself. I mean that as a friend, okay?
