Locke: I'm sorry Hugo. You don't get to quit.

Locke: Thank you Henry. Thank you for not leaving me.

Locke: What are you doing?
Eko: I'm taking this back with us.
Locke: Why?
Eko: Because they may be important.
Locke: Important? I'm sorry, weren't you watching the same thing I was?
Eko: Yes, and I believe the work you have been doing is more important now than ever.
Locke: Work?
Eko: Pushing the button.
Locke: That's not work! That's a joke. Rats, in a maze, with no cheese.
Eko: We are being tested.
Locke: Tested?
Eko: The reason to do it, pushing the button, is not because we are told so in the film.
Locke: Well, then what is the reason, Mr. Eko?
Eko: We do it because we believe we are meant to. Isn't that the reason you pushed it, John?
Locke: I was never... meant to do anything! Every single second of my pathetic little life is as useless as that button! You think it's important? You think it's necessary? It's nothing, it's meaningless; and who are you to tell me that it's not?

Locke: What did one snowman say to the other snowman?
Desmond: "Smells like carrots."
Locke: Hello, Desmond.
Desmond: "Hello" yourself, box man.

Locke: Who are you?
Gale: My name is Henry Gale. I'm from Minnesota and I crashed on this island just like you.

Locke: Why would your own people want to kill you?
Henry: Because the man in charge... He's a great man, John, a brilliant man... but he is not a forgiving man.

Locke: You're lost already?
Eko: Your map is inexact.
Locke: No kidding.

Locke: You've given up the right to be believed!

Locke: [to Helen] Will you marry me?

Michael [staring at the gun]: I'm sorry.
Ana-Lucia: For what?
(Michael shoots Ana-Lucia. Libby appears)
Libby: Michael?!
(Startled, Michael shoots Libby. He then opens the gun vault, aims the gun at Henry, then shoots himself in the left shoulder)

Michael: Well I guess I know why the shark is hanging around. Your shoulder.
Sawyer: Oh, well I'll just stop bleeding then.

Michael: Everything is cool. We had a talk and they believe we were on the plane too.
Sawyer: Swell. I guess we can all sue Oceanic together.

Michael: I hear you're a priest.
Mr. Eko: Yes.
Michael: I guess you believe in hell, then?
Mr. Eko: For a brief time, I served in a small parish in England. Every Sunday after mass, I would see a young boy waiting at the back of the church. Then one day, the boy confessed to me that he had beaten his dog to death with a shovel. He said the dog had bitten his baby sister on the cheek and he needed to protect her. And he wanted to know whether he would go to hell for this. I told him that God would understand, and that he would be forgiven, as long as he was sorry. But the boy did not care about forgiveness. He was only afraid that if he did go to hell that the dog would be there, waiting for him.

Michael: Who are you people?
"Henry Gale": We're the good guys, Michael.

Military Officer: [to Desmond about the Dickens book] Enjoy your sodding book.
