Goof: When Mac answers the phone when Christine calls the first time, you can clearly see the cellphone is showing a locked screen instead of an incoming call. The phone didn't really ring at all.
Mac: Christine was so excited about going to Vegas. They took her before she made it out of New York.
D.B.Russell: Mac, we're gonna get her back.
Mac: Where is she? Where's Christine?
D.B.Russell: Hey! My friend asked you a question.
Zane Kalim: Your friend won't like the answer.
Mac: What'd you do to her?
Zane Kalim: You will never see her again.
Mac: Where is she being held?
Zane Kalim: She must be important to you. You only ask about her.
Zane Kalim: Leave it to the Boyd brothers to kidnap a cop's girlfriend.
Mac: You took Christine and Shawn as collateral for the $100,000 he and his brother owed you.
Zane Kalim: Everyone needs insurance.
Mac: Did you do something to her? Is she alive?
Zane Kalim: I'm done talking.
(Mac makes pressure with his hand over Zane's bullet wound, making it bleed. Zane groans in pain)
Mac: You can end this. Just tell me what you did with her.
Zane Kalim: Go to hell.
Christine Whitney: If you kill us, then you'll lose the only leverage that you've got.
Omar: What kind of leverage could you possibly be?
Christine Whitney: My... my boyfriend's a cop.
Lindsay: I feel so helpless, knowing that Christine is out there alone.
Hawkes: I know. We just got to stay positive for Mac.
Flack: Mac. This was left for you at the front desk.
Mac: What is it?
Flack: I don't know. It just came in.
(Mac opens it to find a severed tongue inside)
D.B.Russell: This is a lot for anyone to handle. Even Mac.
Jo: He puts the burden of the case on his shoulders even when it's a stranger. Now that it's Christine, it makes me worry for the people he's after because he's not gonna stop till he finds them.
D.B.Russell: Mac's lucky to have you. All of you.
Danny: DNA came back on the tongue. Belongs to a male.
Jo: Oh, thank God.
Danny: What the hell's going on, Jo? Why make contact with us just to take us for a ride?
Mac: They had Christine call my cell phone. She gave me an address of a warehouse. Said to come alone. Told me if I didn't, they'd kill her.
D.B.Russell: Well, Mac, they just separated you from your team.
Mac: Look, I know what I'm doing, D.B. You of all people should understand that.
D.B.Russell: I do understand. That's why I'm here. I'm not trying to stop you, but I'm not gonna leave you alone either.
Jo: Mac feels he needs to go with this alone, we need to trust him. Our job is to follow the science, just like any other case.
Mac: I can't take any chances, Don. Not on this one.
Flack: So what? We just... spring the dude and walkhim out the front door as the federal marshals are walking in?
D.B.Russell: It's my fault. Uh, when I was booking Kalim, I filled out the wrong... the wrong form. Those damn things look so different in Vegas, and I'm a little tired to tell you the truth.
Mac: We're gonna go get Christine together, or I'm gonna shoot you dead right now. Where is she? I'm tired of playing games. Let's play one of mine (Empties his gun but for one bullet)
Mac: We'll see how far you're willing to go.
Christine Whitney: (Sobbing) Thank God, Mac.
Mac: Shh. It's okay, it's okay. Okay. It's okay, it's okay. You're safe now. You're safe.
Christine Whitney: I knew you'd come for me.
Christine Whitney: I love you, Mac.
Mac: I love you too.
Mac: What'd the marshals say?
Flack: They were pissed. But they'll get over it. Not much you can do. Clerical errors tend to happen from time to time.
Jo: Thank God we got Christine back. How is she?
Mac: Thankful it's over.
Mac: I'm sorry I kept you in the dark. If there was any other way...
Jo: I know.
Jo: The guy you arrested... Omar. He told this wild story about playing a game of Russian roulette. You wouldn't happen to know anything about that, would you?
Mac: Not much of a game when the gun's empty.
D.B.Russell: Just when you think you got a moment to yourself, somebody knocks on your door.
Mac: Well, I guess that's the job we signed up for.
D.B.Russell: There's got to be some perk to being the boss, right?
Mac: Yeah, the seminar in Hawaii comes to mind.
D.B.Russell: How's Christine doing?
Mac: She's coming along. I was just about to head back to the hospital.
D.B.Russell: I guess it's your turn to take care of her, huh?
Mac: Yeah, it is.
Mac: D.B., I can't thank you enough for coming back here with me.
Mac: No, no. You stuck your neck way out on the line. Much more than I could have asked for. I want you to know how grateful I am. Thank you. Next time we come to Vegas, dinner's on me.
D.B.Russell: Damn right. I'm gonna bring my whole family, too.
