Grissom: According to Cydan's research the hormone levels in the tap water are nearly equal to the water in the reservoir.
Catherine: I thought they drink ground water.
Grissom: They do. Cydan was convinced that the ground water was contaminated.
Catherine: How?
Grissom: He discovered that the reservoir was improperly lined allowing grey water to leach into the ground water.
Nick: Well, if that's the case, why didn't any of the other boys develop breasts?
Grissom: There's a good chance that others have been affected. Especially children who were born to women who were living there while they were pregnant.
Catherine: Because the womb is the only place that human lives in fluid, like a fish.
Nick: That reservoir is supposed to be lined to prevent contamination. The lining is ineffective.
Grissom: Obviously it's not. Which I think is the conclusion that Cydan came to the night before he was shot. (edit) Warrick: I think Brian killed himself.
Nick: You think that he climbed into that big ol' tree all by himself?
Warrick: Yeah.
Nick: Okay, yeah. What about the mutilation?
Warrick: Self-inflicted. It took awhile but Mandy was able to get prints from the beer bottle, they came back to Brian.
Nick: So, this was a hate crime.
Warrick: Yeah, he hated himself. (edit) (After Grissom asked her to marry him)
Hodges: You look like you're having a good day.
Sara (a little taken aback, trying not to smile): Thanks. (edit) (After Grissom asked Sara to marry him)
Catherine: Hey, what are you up to?
Grissom (defensive): Nothin'. Why? (pauses) What's in the cooler.
Catherine: Carp. Paul Cyden died holding one. He had a freezer full of them, some kind of an expierment.
Grissom: Huh. I can process those fish if you want.
Catherine: Do I know how to turn you on or what? (edit) Grissom (Sara has on bee suit): Oh, you know I love it when you dress up.
Sara (laughs): Well, whatever it takes to get time with you. (edit)

Knowing Grissom and Billy Petersen are farsighted - how can he scrape the sting off Sara's hand without wearing his glasses? (edit)

This episode deals with water contamination and its effect on local wildlife and people, which is the main storyline in the 2000 film "Erin Brockovich", which also starred Marg Helgenberger. (edit) The name Jonah Quinn has also been used in the Stargate SG-1 series in season 6 only spelled slightly different (Jonas Quinn). Also William Russ, the actor playing Jonah Quinn, appeared in the show's episode The First Commandment as Sam Carters ex-fiancé. (edit) Hodges: Do I look like the ghost whisperer?

Referring to Melinda Gordon from the CBS drama Ghost Whisperer, who has the ability to communicate with the dead. (edit) When Nick is checking the phone messages one is from PCYDEN. "Poseidon" in Greek mythology is the God of the Sea. (edit)
