Jack: How're you doing?
Charlie: How am I doing? With week two of heroin withdrawal? Or how am I doing with Claire being abducted by the freak who tried to kill me?
Jack: I gave you aspirin for the heroin withdrawal.

Jack: I can't.
Locke: Why can't you?
Jack: Because I'm not a leader.
Locke: Yet they all treat you like one.
Jack: I don't know how to help them. I'll fail. I don't have what it takes.

Jack: If we survive this, if we survive tonight, we're gonna have a Locke problem. And I need to know that you got my back.
Kate: I got your back.

Jack: It's been six days, and we're all still waiting. Waiting for someone to come. But what if they don't? We have to stop waiting. We need to start figuring things out. A woman died this morning just going for a swim. He tried to save her and now you're about to crucify him. We can't do this. Every man for himself is not going to work. It's time to start organizing. We need to figure out how we're going to survive here. Now I found water. Freshwater, up in the valley. I'll take a group up there at first daylight. If you don't want to come then find another way to contribute! Last week most of us were strangers. But we're all here now. And God knows how long we're going to be here. But if we can't live together--we're gonna die alone.

Jack: This is bad.
Michael: Yeah. I mean, I know what I would do, but... this has gotta be your call.
Jack: All right... give me the 7 iron.

Jack: Three days ago we all died. We should all be able to start over.

Jack: We don't have time to sort out everybody's God.
Charlie: Really? Last I heard we were positively made of time.

Jack: What do you think his story is?
Charlie: Who, Locke? Guy's a freak of nature. Highly disturbed. Chances are he probably killed all his mates at the post office the day his mum forgot to put a cookie in this lunch tin. That was my first impression anyway. Then he saved my life.
Jack: Then you trust him?
Charlie: Trust him? No offense, mate, but if there was one person on this island that I would put my absolute faith in to save us all, it would be John Locke.

Jack: What is that?
Charlie: Claire's diary.
Sayid: You read her diary?
Charlie: Yeah, I know. I'm bloody scum.

Jack: What the hell was all that about back there, John?
Locke: What was what about?
Jack: You asked me to let you go.
Locke: That's right.
Jack: That thing was taking you down the hole and you asked me to let you go.
Locke: It wasn't going to hurt me.
Jack: No, John, it was going to kill you.
Locke: I seriously doubt that.
Jack: Look, I need for you -- I need for you to explain to me what the hell's going on inside your head, John. I need to know why you believe that that thing wasn't going to...
Locke: I believe that I was being tested.
Jack: Tested?
Locke: Yeah, tested.
Jack: I think...
Locke: That's why you and I don't see eye-to-eye sometimes, Jack -- because you're a man of science.
Jack: Yeah, and what does that make you?
Locke: Me, well, I'm a man of faith. Do you really think all this is an accident -- that we, a group of strangers survived, many of us with just superficial injuries? Do you think we crashed on this place by coincidence -- especially, this place? We were brought here for a purpose, for a reason, all of us. Each one of us was brought here for a reason.
Jack: Brought here? And who brought us here, John?
Locke: The island. The island brought us here. This is no ordinary place, you've seen that, I know you have. But the island chose you, too, Jack. It's destiny.
Jack: Did you talk with Boone about destiny, John?
Locke: Boone was a sacrifice that the island demanded. What happened to him at that plane was a part of a chain of events that led us here -- that led us down a path -- that led you and me to this day, to right now.
Jack: And where does that path end, John?
Locke: The path ends at the hatch. The hatch, Jack -- all of it -- all of it happened so that we could open the hatch.
Jack: No, no, we're opening the hatch so that we can survive.
Locke: Survival is all relative, Jack.
Jack: I don't believe in destiny.
Locke: Yes, you do. You just don't know it yet.

Jack: You've got hyperopia.
Sawyer: Hyperopia? That's..... What is that?
Jack: You're farsighted.

Jin: [about Sun] In a good world... she would hate her father, not me.
Jin's father: It is a good world.

Kate: [About her T-shirt] It was, uh, it was full of bees.
Charlie: I'd have thought C's, actually.

Kate: [as she is about to stitch up Jack's wound] Any color preference?
Jack: Nah, standard black.
Kate: I might throw up on you.
Jack: You're doing fine.

Kate: [to Sawyer] I don't feel sorry for you, I pity you.
