|Catherine: "Who's pulling the strings? It has to be someone in his organization."|
Sarah: "I'm going with Occam's Razor. Sometimes the simplest answer is often the right answer."
|DB: Y"ou alright?"|
Catherine: "Considering I've been shot and cauterized by a hooker's curling iron, I guess."
|Catherine: "You may not be getting that back."|
Jack: "Darlin' the way your handling that piece, I bet I will."
|DB: "What tipped you off?"|

Russell: Yeah, right."
|Brass: "Sick bastard took her eyes, why?"|

|Julie: "We need a safe word for when that Zen crap starts."|
Russell: "Pick one."
Julie: "Ok, how about "Stop" - will that work?"
|Julie: "Think you're getting kind of forgetful. Must be all that "zen master - living in the moment stuff."|
Russell: [smiles] "Yeah."
|Russell: "Wish me luck."|
Henry: "Where you going?
Russell: "We need a blood-whisperer."

Greg: "Rumors are that you fired her."
DB: "Right again."
|Hodges: "528, that's the right address."|
Nick: "As opposed to the other houses that were stolen last night?"

Dwayne: "Yes, that is what I'm trying to tell you people!"
Nick: "Think someone was after the house of the wife?"

|DB: "What are you going to do, make your son pay for your sins."|
|Finn: "What are you doing out here? Communing with the stars?"|
DB: "My phone is communing with the charger."
|DB: "I'll have Morgan call maintenance."|
Hodges: "She might dial the phone a little faster if you omit the part about me being in here."
DB: "What, are you guys in high school?"
|Finn: "You know the rule, if we don't find this in 3 hours, he's dead."|

Professor: "Didn't seem like I had a choice."
DB: "You didn't, have a seat."
|DB: "Help us out, give us what we need to rule you out and these pictures will get buried in the evidence vault. [looks at Brass] We can do that right?"|
|Greg: "It's Pete's phone."|
Nick: "Think this is Pete's killer?"
