Kate: We have to go back.
Sawyer: What the hell are you talking about?
Kate: Turn the boat around, Sawyer, I mean it.
Sawyer: Have you lost your mind?! We just got away!
Kate: Just do it.
Sawyer: You give me one good reason to turn around...
Kate: Because we can't leave Jack behind!
Sawyer: Yes, we can, Freckles. 'Cause that's what he asked us to do. You think about it, we go back there... whaddya think Captain Bunnykiller's gonna do if he catches us?
Karl: Kill you. God loves you as he loved Jacob.
(Kate and Sawyer stare at Karl)
Sawyer: O-kay! Thanks for the input!

Tom: Time to get up. We're moving ya.
Jack: Moving me where?
Tom: Some place else, Jack.
Jack: Why? So this is it, huh?
Tom: 'It'?
Jack: You just helped me save his life. If you're gonna kill me, please at least show me the respect of not calling it 'moving'.
Tom: Now, why would we kill you?
Jack: Because you're done with me.
Tom: What kinda people do you think we are, Jack?
Jack: Oh, I don't know, Tom. The kinda people that would take a pregnant woman... would hang Charlie from a tree... would drag our people outta the jungle... would kidnap children! That's the kinda people I think you are.
Tom: (knocks on the glass) You see this glass house you're living in, Jack? How about I get you some stones?

Karl: God loves you as he loved Jacob.

This is a Biblical reference to Jacob, son of Isaac and twin brother of Esau.

Tom: (knocks on the glass) You see this glass house you're living in, Jack? How about I get you some stones?

This is a reference to the expression: "People who live in glass houses shouldn’t throw stones." It means we shouldn't say bad things about people if we're just as bad as them.
