Jack: I was thinking that if we were living at the caves, we could build a damn around that spring so that everybody could have fresh water and we could get the infirmary off the beach. You think it's a bad idea?
Kate: No. No, it makes sense.
Jack: But ...?
Kate: No "but".
Jack: Good. Because a lot of people are still hoping a rescue boat's gonna show up. They're not thinking about their own safety. We're gonna have a lot of convincing to do.
Kate: "We"? You still haven't convinced me yet.
