Ben Linus: Are you thirsty?
John Locke: This is the well I threw Desmond Hume into.
Ben Linus: What's the matter?
John Locke: I sent Sayid to kill Desmond. Obviously he didn't.
Ben Linus: Looks like someone helped him out.
John Locke: No Ben, someone helped me out.
Ben Linus: What did Widmore say to you?
John Locke: He said Desmond was a fail safe. Jacob's last resort in case God forbid, I managed to kill all of his beloved candidates. There's one final way to make sure I'll never leave this place.
Ben Linus: Then why are you happy he's still alive?
John Locke: Because I'm gonna find Desmond and when I do, he's gonna help me do the one thing that I could never do myself. I'm gonna destroy the island.

Ben Linus: It's C4, Richard. I put some thought into hiding it.
Miles Straume: Let me guess, cookie jar?
