Jack: Juliet marked three tents; that means we need three guns.
(Karl whips out his gun)
Hurley: Whoa! (jumps behind Jack)
Karl: Here, you can have mine too.
Rousseau: I'll be your third.
Jack: We'll take your gun, but you're not staying here. You're gonna lead everyone to the radio tower. Everyone!
Claire: Radio tower!?
Jack: Now, if this doesn't work, we can't risk losing the chance of getting in contact with Naomi's boat. So everything has to happen at the same time. Charlie, you still up for a swim?
Charlie: Yeah, I believe I am.
