Lost, Season 4

Jack Shephard:
We're gonna have to lie.

Sayid Jarrah:
Lie about what?

Jack Shephard:
Everything, all of it, every moment since we crashed on the island.

Frank Lapidus:
Jack... now I know I'm new to this group and everything, but isn't this the place where everybody starts jumping up and down and hugging each other?

Jack Shephard:
Your freighter... those men came to the island to kill us, all of us. You said that our plane was discovered on the bottom of the ocean. Well, someone put it there--someone who wants everyone to think that we're dead. So what do you think's gonna happen to us when we tell them that that wasn't our plane? What do you think's gonna happen to the people that we left behind?

Kate Austen:
Jack, we can't. We can't pull it off.

Jack Shephard:
Just let me do the talking.
