CSI: Miami Season 4 Episode 17

(Calleigh enters the lab where Ryan is checking on possible weapons that could have made the head wounds)
Calleigh: I'm stepping out for a bite. Would you like something?
Ryan: No no, I'm cool.
(Ryan asks for Calleigh's opinion and Calleigh suggests that it was a gun, maybe pawned with the necklace)
Calleigh: Looks like lunch is a drive-thru.

(Ryan enters the lab where Calleigh is looking at the diamond)
Ryan: Check out the carat weight?
Calleigh: Carat weight is its value in the real world, my friend. I'm checking its value to us.
Ryan: Which is?
Calleigh: The girdle.
Ryan: ...Excuse me?
Calleigh: On a diamond, the girdle is the rim that's formed at the top of the stone and that's where they place the DIA number.
Ryan: Right, Diamond Index of America.

Benchley: I was the only man for her.
Horatio: But she disagreed with you.
Benchley: She just needed convincing.
Horatio: So in order to convince her you killed her.

Benchley: You won't believe me, but I didn't come to town to kill her.
Horatio: You're right, I don't believe you.

Calleigh: Pawn shop guy said he wiped it down before he planned to move it. You know, no one wants to buy a dirty gun.
Delko: Well, there's pawn shop clean and then there's CSI clean.

Benchley: I followed her to try to get some dirt, regain custody. You know, she's the crazy one.
Horatio: Yes, and now she's the dead one Howard, so mission accomplished for you.

Benchley: Look, there was nothing I could do.
Calleigh: Really? Cause you could have killed her and stolen a four million dollar necklace.

Calleigh: We find the clues, we find the car, we find a witness!
Delko: That's right. Or a murder suspect.

Wolfe: I think she was up to no good.
Alexx: If she was Ryan... let her tell us.

Rita Davis: Can I go now?
Horatio: Let me see, how can I put this... no.

Alexx: Baby boy has red dye on both his hands.
Delko: Any theories?
Alexx: Working on it.
Delko: Let me guess - you'll know more at the post.
Alexx: (smiling) Always do.

(Frank kicks open the trunk to reveal a dead man)
Frank: Interesting use of cargo space.
Horatio: That would explain why our driver was moving so fast.
Frank: One thing's for sure, she was hauling ass.
Horatio: Yes Frank, a dead body can have that effect on you.

Frank: We found male DNA on Luis, south of the border. We think it might be yours.

Howard Benchley: Do I look like a guy who just came into a fortune?
Calleigh: I don't know Mr. Benchley but you don't look innocent.
