The title phrase, "Primum Non Nocere" is a Latin phrase that means "First, do no harm." The phrase is sometimes also written as "primum nil nocere". The term is one of the principal memes that all medical students are taught at med school (and is present, in a similar form, in the Hippocratic Oath) and is a first principle for emergency medical services everywhere.

Gil: Two minutes for elbowing. Four minutes for high sticking. Ten minutes, unsportsman-like conduct.
Sara: Boys will be boys.
Gil:Yeah, It looks like these boys went to a fight and a hockey game broke out.
Sara: You just don't like sports.
Gil: That's not true I've been a baseball fan my whole life.
Sara: Baseball that makes sense, all those stats.
Gil: It's a beautiful game.
Sara: Since when are you interested in beauty?
Gil: Since I met you.

Grissom: What is Victoria's Secret, anyway?
Sara: Beauty, Grissom. Remember?

(Grissom and Catherine walk out onto the ice. Brass is already there in the center. Grissom looks around.)
Gil: Where's the body?
Jim: On the bench -- he was moved there after he collapsed in front of the net. Apparently, uh the guy was responsive enough to be helped off the ice. He
died a few minutes later.
(Brass, Grissom and Catherine cautiously walk toward the bench. Brass removes the blanket covering the body on the bench. Grissom leans in to look at it.)
Gil: (pointing) This looks fresh.
Jim: Well, according to the on-site doctor, he took on across the cheek earlier in the second period.
(Catherine points to the large gash in the side of the neck.)
Catherine: Well, I guess is must be from the third period. Looks like that other team worked him over pretty good.
Jim: Hockey, rough game.
Gil: Yeah, it's murder.

Catherine: So, why did you move the body?
Doctor: You ever tried treating someone on the ice wearing just street shoes?
Catherine: Then Mr. Rivers was still breathing?
Doctor: When I brought him back to the bench, yes. Then I performed CPR, and he didn't respond.
Catherine: Did you also do the stitch work?
Doctor: I'm the on-site doctor for this facility. The stitches held, and I advised Terry not to go back on the ice.
Catherine: So, if he'd listened, he'd still be alive.
(The Doctor sighs. Catherine turns around and looks at all the players in their towels.)
Catherine: What do these guys play for? A little money? Imitation Stanley Cup?
Tommy Sconzo: (quietly) We play for the pride of it.
(Catherine turns around to talk with the player dressing.)
Catherine: And the joy of kicking ass. You are...?
Tommy Sconzo: Tommy Sconzo. Right wing, first line. Hitting's part of the game. Take away the physical aspect you've got figure skating. Guys out there doing triple lutzes.
Catherine: Is that how you lost the, uh...? The sit spin?
Tommy Sconzo: Second period, number nine. The guy's a real McCracken.
Catherine: Which means?
Tommy Sconzo: He gave me a high stick to the mouth. That's why my guys crashed the goalie. An eye for an eye, you know?
Catherine: That why your guy ended up dead?
Tommy Sconzo: What can I tell you, lady? It all happened so fast, you know?
(He turns back to his locker.)
Catherine: Usually does.

Det. Lockwood: Stan Grevey, 35. Backup sax player. One of the waitresses found him.
(Nick and Warrick put their kits down and look at the scene.)
Nick: Tiny scrubbing bubbles.
(Camera zooms in to show the white powder at the corner of the victim's mouth.)
Warrick: Yeah, after somebody wiped them down. Paramedics?
Det. Lockwood: Nope. Just pronounced, that's it.
Warrick: Just pronounced?
(Nick reaches over and lifts the victim's lip up. There's something caught in between his teeth.)
Nick: Had an interesting diet. Cowhide.
(Warrick checks Stan Grevey's arm and finds needle marks.)
Warrick: He tied himself off.
Nick: Yup.
Warrick: All the signs of an O.D ... without any of the paraphernalia.
Nick: Your waitress say anything about a needle butane torch, that sort of thing?
Det. Lockwood: No, not a word just said he reminded her of Coltrane.

Al: What took you so long?
Gil: I was watching ice melt.

Catherine: Catherine Willows Crime Lab. I understand you play for area 51. Did you see much ice time during the game?
Jane Gallagher: No, they just let me take off my cheerleader uniform and warm the bench.
Catherine: You know what? Been there, done that. Just asking a question here.
Jane Gallagher: I played 24 minutes, 12 seconds -- about my season average. I also lead the team in assists.
Catherine: Oh ... you've got good peripheral vision. You see the ice really well.
Jane Gallagher: I didn't see what happened to Terry.
Catherine: You're a real teammate. Down the line, just one of the guys.
Jane Gallagher: You're looking in the wrong direction. Now, we may have disliked Terry, but his own teammates ... hated him.
Catherine: Any reason why?
Jane Gallagher: How would I know? I'm just a girl. Can I go now?
