Horatio and Delko search Miami to bring down the Mal Noche gang once and for all after the murder of someone very close to them. However, their quest is jeopardized when the Feds seize the CSI lab with the intent to close it for good, based on the tip from the mole inside. When the mole is finally revealed to the entire lab, the news sends the remaining CSIs reeling.
Dan Cooper: Damn!
Natalia Boa Vista: What was that about?
Dan Cooper: I'll tell you what that was about - Valera's the mole.
Natalia Boa Vista: What?!
Dan Cooper: Yep, that's how the feds operate.
Natalia Boa Vista: Yeah, 'cause you're a big FBI expert.
Dan Cooper: It's what they do, they start an investigation, put in an operative...
Natalia Boa Vista: (scoffs) An operative?
Dan Cooper: Which they make sure they get out before the fur starts to fly.
Natalia Boa Vista: Cooper, you've seen way too many Tom Clancy movies.
Wolfe: Wait a minute... you're babysitting me?
Agent Heather Landrey: Fed outranks local. Every time.
Agent Heather Landrey: Oh, and CSI Wolfe? Thanks for your co-operation.
Wolfe: For the record, I didn't co-operate.
Agent Glen Cole: If I find any evidence of wrongdoing, I'll shut your lab. And you, Lieutenant, will go down with it.
Horatio: Duly noted, now beat it.
Wolfe: You told the feds I have keratitis.
Dan Cooper: You said you did!
Wolfe: I told you to draw out the mole and I guess it worked 'cause you told the feds, YOU TOLD THE FEDS!
Dan Cooper: Hey, I had a few beers with some of the feds after basketball, man, it must've slipped out!
Calleigh: The two of you need to cut this crap out!
Wolfe: (to Cooper) You're the mole.
Dan Cooper: Hey, I told you it slipped out!
Calleigh: It doesn't matter, we're trying to figure out the murder of a police officer.
Delko: H, it's our move.
Horatio: We're going to Brazil.
