Mac Taylor: I want the girl, Olivia. Tell me where she is.
Kenny Hexton: I don't know.
Mac Taylor: Well, then I don't know where you might end up. I'm thinking maybe, uh, New Mexico right now. How about that?

Mac Taylor: I'm sorry you had to go through that, Billy.
Billy Travers: Yeah. I get it. You were just doing your job, I guess.
Mac Taylor: You know, sometimes we lose sight of how hard it is to be called a suspect.

Mac Taylor: If this is gonna work we got to trust each other. The DD-5 documenting Grace Travers recanting the I.D.... I saw you looking at it. Damaging to the case... you thought maybe I wouldn't file it?
Jo Danville: History has a tendency of repeating itself.
Mac Taylor: What happened in D.C. is not a part of my history.

Mac Taylor: It's over, Tom! Put down your weapon! I know what happened to your brother!
Tom Reynolds: You don't know anything!
Mac Taylor: I know what happened to him. I was there. I know what happened to you.

Mac Taylor: Judge let Billy Travers out on bail. As of now, the mother's I.D. is all we have and I'm not even sure we have that.
Jo Danville: Should we offer her some kind of protection?
Mac Taylor: She'll refuse. She's on her son's side now. So unless we come up with a forensic link, he'll be at her bedside by the end of the day.

Mac Taylor: Michael had a brother... Tom Reynolds.
Lindsay Monroe: Mitochondrial DNA from the hair was a match to Michael.
Mac Taylor: Mito's shared by all maternal relatives, including brothers, so it would also be a match to Tom.
Lindsay Monroe: So he's our shooter. Why?
Jo Danville: Off to one side, unnoticed. Everyone else around him is celebrating Michael's return. Tom is just standing there.
Mac Taylor: Emotionless, neglected.
Lindsay Monroe: So you're telling me he starts shooting people 'cause he didn't get enough hugs and kisses from mommy and daddy?

Mac Taylor: Michael had been missing for 72 hours when this case file came across my desk. He was on his way home from school when he was abducted.
Jo Danville: Did you catch the guy?
Mac Taylor: Took 3 years. Arthur Francis. Twice convicted sex offender. Whole time he was missing, we didn't know whether he was alive or dead. It was the first case I ever questioned which of those two options might be worse.
Jo Danville: I'm sure his own parents asked themselves the same thing.
Mac Taylor: At age 12, he finally managed to escape. Clawed his way through the floorboards to a crawl space.
Jo Danville: I can't imagine that moment for a 12-year-old kid. It's heartbreaking.
Mac Taylor: I went to see him a few times after he returned home. Made sure he was doing all right. He always wanted to wear my badge. He asked me if it was pure gold the first time he put it on. His brother Tom, too. I thought for sure one of those boys would become a cop. I tried to stay in touch with the family, but then another case came along, then another case and I lost touch. Now he's the primary suspect in a murder investigation.
Jo Danville: Mac... there's only so much this job allows us to do.

Mac Taylor: Mrs. Travers, did someone in your family do this to you?
[Mrs. Travers moves her finger up and down, meaning "yes"]
Mac Taylor: [to an officer)] Give me that picture over there. Right there. Come on. Come on. Mrs. Travers, I need you to listen very carefully... [pointing to Billy Travers] Is this the person who did this to you?
[Mrs. Travers moves her finger up and down, meaning "yes"]
Mac Taylor: Is this your son? Did your son do this to you?
[Mrs. Travers moves her finger up and down, meaning "yes"]
Mac Taylor: We got to find this kid right away.

Mac Taylor: Mrs. Travers, do you remember what happened last night?
Grace Travers: No. I just remember waking up in this room.
Mac Taylor: I realize this is hard, but can you tell me why your son would have done this?
Grace Travers: Billy?
Mac Taylor: Yes.
Grace Travers: You think Billy did this to me?
Mac Taylor: Last night, you identified your son. To me. I showed you a photograph and you indicated that he had done this.
Grace Travers: No... no, I did no such thing. No, Billy didn't do this. He would never do anything to hurt me or his father.
Mac Taylor: Mrs. Travers, I know you've been through a lot...
Grace Travers: Who are you?
Mac Taylor: My name is Mac Taylor.
Grace Travers: Why did you come here? To tell me that my son did this to me? To tell me these lies?
Mac Taylor: I don't want to upset you...
Grace Travers: No, you listen to me! You leave Billy alone, do you understand me? He would never do this! Now, go! Get out! Leave my family alone!

Mac Taylor: Olivia Dalton. That's your name. You're from Queens, New York. Your mom's name is Natalie. Remember? I saw her just before I came here. She wanted you to know that she never forgot about you. She never stopped looking for you. She never stopped hoping that you were out here somewhere... alive. She loves you, Olivia.
Olivia Dalton: (About Wes) He loved me, too. My father loved me.

Mac Taylor: Our hope is that this was an isolated incident and that the shooter will be in custody soon. I know that's what the brass wants the public to believe. What I don't know... what we can't know... is when or where the killer will strike again.

Mac Taylor: Poisoned and left to die. This was personal.

Mac Taylor: Significant blood loss. She couldn't have gone far. She was murdered right here in the school grounds.
Don Flack: Usually you tell your kids to be careful coming home from school, not through it.

Mac Taylor: Since when were Stalin, Khrushchev, and Beria ingredients in water?
Lindsay Monroe: Never...
Sheldon Hawkes: I don't think there's 1947 calories in it either.
Jo Danville: Where did that water bottle come from?
Sheldon Hawkes: Vics' backpack.
Mac Taylor: [Looking at the water bottle closely] Heh, Multiple Choice. 1-T-D
Lindsay Monroe: 1947. TD. Truman Doctrine.
Mac Taylor: 2-M-P
Jo Danville: Marshall Plan.
Mac Taylor: 3-N-S-A
Lindsay Monroe: National Security Agency.
Mac Taylor: National Security Act, Agency wasn't formed until 1949. Everything on this bottle has been replaced with information pertaining to the Cold War.
Jo Danville: All the answers to the test. It's a cheat sheet.
Sheldon Hawkes: That's impressive.
[Mac looks at him wondering]

Mac Taylor: So how'd your negotiation go yesterday?
Jo Danville: Negotiation?
Mac Taylor: Your daughter seems rather determined to vacate New York City.
Jo Danville: She can be a stubborn mule like her mama. Seldom shy about what she likes and doesn't like.
Mac Taylor: Being thrown into the deep end is never easy. It helps to know there are people around that have your back.
Jo Danville: Well, Ellie's a tough kid. She's going to be fine.
Mac Taylor: I wasn't talking about Ellie.
Jo Danville: Thank you.
