Jack: [to Ana Lucia] How long would it take to train an army?

Jack: [To Sawyer about Locke's hunting] Well if you've gotta better idea?
Sawyer: Better than the three of us wandering into the magic forest to bag a hunk of ham with nothing but little bitty hunting knife? Hell no it's the best idea I ever heard. [Locke reveals his suitcase full of hunting knives.]
Hurley: Who is this guy?

Jack: [to Sawyer] Hey, what are you doing?
Sawyer: What's it look like? (arming self) I'm coming with ya.
Jack: You're still on antibiotics.
Sawyer: It's a good thing I'm traveling with my doctor then.

Jack: [Trying to get Shannon's inhalers] You attacked a kid for trying to help his sick sister.
Sawyer: No, I whooped a thief 'cause he was going through my stuff--
Jack: Yours? What makes it yours?
Sawyer: --which I had to move because everybody wants to help themselves.
Jack: You can just take something out of a suitcase, and that makes it yours?
Sawyer: Look, I don't know what kind of commie share-fest you're running over in cave town, but down here possession's nine-tenths and a man's got a right to protect his property.
Jack: Get up!
Sawyer: Why, you wanna see who's taller?
Jack: I said get up!

Jack: A-rod...
[...]:
Jack: Mornin'.
Kate: Morning yourself. I bought you a razor.
Jack: What, you don't like the scruff?
Kate: [Laughs softly] Razor's by the sink, Jack.
[Jack picks a towel for her]
[They kiss]

Jack: Are you ever gonna take us off this island?
Daniel Faraday: No.

Jack: Better get going. Rousseau said it's about a day's walk up to the radio tower.
Sayid: I'm not taking them up to the tower--you are.
Jack: Excuse me?
Sayid: You're not staying behind.
Jack: This was my idea.
Sayid: And I'm perfectly capable of executing it.
Jack: I owe them!
Sayid: What are you more concerned about: killing the Others or getting our people off this island? This afternoon you said you were our leader. It's time for you to act like one. Lead them to the radio tower, Jack and then take us all home.

Jack: Desmond, you've done enough. You want to do something, go home and be with your wife and son.
Desmond: What about you, Jack?
Jack: I'll see you in another life, brother.

Jack: Do you ever miss?
Hurley: Jack.
Jack: Yeah, I was on my way back from a consult. Thought I'd drop by and pay you a visit. Horse?
Hurley: You're on. So consult huh? Does that mean you're back doing surgical stuff? (Jack starts playing basketball with Hurley)
Jack: Yeah. (Hurley shoots and scores. Jack shoots and misses) H
Hurley: Reporters leaving you alone? (Hurley shoots and scores)
Jack: Yeah. Still have to sign some autographs when I go out for coffee. Thinking about growing a beard. (He shoots and misses again)
Hurley: You'd look weird with a beard, dude. That's H O. So, what are you really doing here, Jack?
Jack: I was just checking on ya, seeing if everything was ok.
Hurley: Checking to see if I was nuts, if I was gonna tell.
Jack: Are you?
Hurley: You're up.
Jack: Nah, you win. I, er, I gotta run. It was great seeing you Hurley. (Jack starts to leave)
Hurley: I'm sorry. I'm sorry I went with Locke. I should have stayed with you.
Jack: Its water under the bridge, man.
Hurley: I don't think we did the right thing, Jack. I think it wants us to come back.
Jack: Hurley.
Hurley: And its going to do everything it can...
Jack: (Shouts) We're never going back!(Jack heads for the door)
Hurley: Never say never, dude.

Jack: Do you know how to use a gun?
Sawyer: Well, there's one polar bear that seems to think so.

Jack: Everyone who was in the rear of the plane is dead.
Rose: They're probably thinking the same thing about us.

Jack: He (Boone) didn't die, he was murdered.
Kate: Where are you going?
Jack: To find John Locke.

Jack: Hey, Hurley.
Hurley: Hey, Jack.
Jack: Why aren't you taking your meds?
Hurley: 'Cause we're dead... all of us. All the oceanic six. We're all dead. We never got off that island.
Jack: Hurley... that is not true.
Hurley: What'd you do today?
Jack: What did I do today? I,uh... [Sighs] I woke up, took a shower. Uh, Kate and I fed the baby.
Hurley: I thought you didn't want anything to do with Aaron.
Jack: I changed my mind after the trial.
Hurley: Living with Kate... taking care of Aaron... it all seems so perfect... just like heaven.
Jack: Just because I'm happy doesn't mean that this isn't real, Hurley.
Hurley: I was happy, too, Jack... for a while, anyway. Then I saw Charlie. He likes to sit with me on the bench out on the front lawn. It's pretty cool, actually.
Jack: Okay. [Sighs] so what do the two of you talk about?
Hurley: Well, yesterday, he told me you were gonna be coming by. He wanted me to give you a message.
Jack: A message?
Hurley: [Opens the drawer] He made me write it down so I wouldn't mess it up. "You're not supposed to raise him, Jack" Does that make any sense?
Jack: No, that...doesn't make any sense.
Hurley: Do you think he means Aaron?
Jack: Take your meds, Hurley. Just take them.
Hurley: Hey, Jack? Charlie said someone's gonna be visiting you, too. Soon.

Jack: Hey. Are you all right? [He touches Juliets face]
Juliet: He wanted me to kill them. Ben. He sent Harper to tell me to kill them.
Jack: How could he possibly tell you that?
Juliet: I don't know! But he knew how to get to me. Don't you see? These people came here to wage war against Ben. And Ben's going to win. And when he does you don't want to be anywere near me.
Jack: [Quietly]: Why not?
Juliet: [Pause]: Because he thinks that I'm his. And he knows how I feel about you.
[Jack walks up to Juliet, and kisses her]
Jack: He knows where to find me.

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.
