Frank: I'm still here, Chief.
John Sullivan: You on the job?
Jack Shepard: Long time ago. Do I know you?
John Sullivan: Do I look familiar?
Jack Shepard: No. What house you work?
John Sullivan: 7-4 homicide.
Jack Shepard: Hot shot.
John Sullivan: No, just working the job. As a matter of fact, I caught a case that goes back to your day. One of the Nightingale murders.
Jack Shepard: No kidding.
John Sullivan: No. Missing teenager, disappeared back in '68. Found her bones last week buried out by some old diner by Dyckman Street. Mary Finelli. Yeah, talk about dumb luck. The odds of anyone finding that 30 years later and the chance of hitting a dental? Forget about it. The best part is, she's the first victim. She knew the killer, so I bet those old bones are gonna do a lot of talking. Not for nothing, the past is a funny thing. We all have skeletons in the closet, we just don't know when they're gonna pop up and bite us in the ass. Huh, Jack? You changed your MO, 'cause if they knew your mother was the Nightingale, they would have looked at the family. They would have looked at you.
Jack Shepard: What are you looking at?
John Sullivan: Stealing your life away. You went down 30 years ago, pal. You just don't know it yet.
John: I want you to remember this word, okay? It's kind of like a code word: Yahoo. Can you remember that?
John Sullivan: Ya'know the past is a funny thing, we all got skeletons in closet and ya never when one is gonna pop up and bite ya in the a...
Frank Sullivan: John, say hello to my wife Julia.
John Sullivan: Hi.
Julia Sullivan: Hi John. Frank tells me you're a cop.
John Sullivan: Yeah, that's right.
Julia Sullivan: My six year old keeps telling us he wants to be a policeman right after he retires from the majors. We just bought him a badge and a whistle for his birthday.
John Sullivan: Yeah, I remember I used to play cops and robbers all the time, and y - my mom wouldn't let me have a toy gun.
Julia Sullivan: Sounds like your mom and I would get along.
John Sullivan: Yeah, she's pretty special. I'm real proud of her.
Julia Sullivan: I bet she's proud of you too, being a cop and all.
John Sullivan: I hope so. I hope she knows how much I love her.
Julia Sullivan: She knows. Mom's always know how much their kids love them, even if they don't tell them all the time. Well I gotta go. It was good talking to ya John.
John Sullivan: You too.
[Offering John coffee]
Fred: You want black? Sugar?
John: It's all good.
Fred: You'll get black
John Sullivan: You gotta be more careful, cause I can't lose you again. Not like that.
Frank Sullivan: You won't John. You won't. I swear to God, no matter what. You got it? You hear me?
John Sullivan: I hear you.
Frank Sullivan: So how old are you?
John Sullivan: I'm 36.
Frank Sullivan: 36. You're all grown up. You must be married and everything.
John Sullivan: No, I'm not married.
Frank Sullivan: What? Too busy playing ball?
John Sullivan: It didn't work out. I gave it up.
Frank Sullivan: What happened?
John Sullivan: I blew my arm out senior year. Didn't have a shot.
Frank Sullivan: Oh, I'm sorry Johnny. I know that had to hurt.
John Sullivan: Thanks.
Frank Sullivan: So what did ya wind up doing? You join the department?
John Sullivan: Actually I went the other way. I'm a cop.
Frank Sullivan: [laughing] What? You're 3rd generation fire fighter. Come on I thought you were gonna grow out of that cop thing.
John Sullivan: Well you got Satch to thank for that one.
Frank Sullivan: You're kidding me huh. Satch? He was always crazy about you ever since you were born. You're still my little chief, right?
John Sullivan: Yeah, I'm trying to be. I'm trying.
John Sullivan: You went down 30 years ago pal you just don't know it yet.
Frank Sullivan: [talking about Julia] Well I just knew. She melted my heart. You got anybody?
John Sullivan: Yeah, kinda. Something I gotta work out, but she's worth it.
[pause]
John Sullivan: You go ahead and get some rest. I'm tired too.
Frank Sullivan: I almost don't wanna click off here. Maybe we won't get this back.
John Sullivan: We will.
Frank Sullivan: Ok. I'll be here tomorrow.
John Sullivan: I know.
Frank Sullivan: I love you son.
John Sullivan: I love you too dad. I missed you so much.
Julia Sullivan: What's going on here, Satch?
Satch: Frank says that he talks to Johnny, little Johnny on the radio in the future, and this guy claims to be your son!
Julia Sullivan: Well, I talked to him too, once. He's a cop.
Satch: You talked to the guy on the radio?
John Sullivan: You changed your mo cause if they knew your mother was a nightingale, they would'a looked at the family. They would'a looked at you.
Jack Shepard: What are you lookin at?
John Sullivan: Stealin your life away.
Frank Sullivan: [talking about the future] You're kidding. You mean, like those big field radios they use in the army?
John Sullivan: No, no, it works off of a satellite. You carry it around in your pocket.
Frank Sullivan: I don't know who you are, I don't know why you're doing this, but let me tell you something, asshole, you stay away from me and my family.
John Sullivan: Listen, I don't know how this is, but it's me, little Chief.
Frank Sullivan: Hey, hey, I am warning you, you touch my kid, I'll hunt you down 'til the day I die.
John Sullivan: But you already died!
Frank Sullivan: What are you talking about?
John Sullivan: The Buxton fire.
Frank Sullivan: [sarcastically] Oh, and when did that happen, 30 years ago?
John Sullivan: October 12th, 1969.
Frank Sullivan: That's tomorrow, I ain't dyin in no fire tomorrow or any other day, you got that?
John Sullivan: You gotta listen to me, it was an abandoned warehouse. Butch always told Ma it wasn't your fault, you went with your instincts. If you've just gone the other way, you could've made it!
Frank: I'm not a cop, I'm a firefighter.
John Sullivan: Do exactly what I say ok?
Gordo Hersch: Bull hicky. You can't tell me what to do.
John Sullivan: Don't screw with me you little pisher, I know everything about you. I have complete knowledge of the universe.
Gordo Hersch: That's not true, only God knows...
John Sullivan: Oh, yeah well who put rubber cement in the coach's jockstrap, or who put the frog in Melissa Gluckman's locker and lets not forget about grandpa's laxative in the sweet potatoes last Thanksgiving. You did all that.
Gordo Hersch: What do you want Mister?
John Sullivan: Ok...
John: Shoulda, woulda, coulda, pal.
