(Jack and Kate on the walkie talk right after Jack cut Ben's kidney sack)
Jack: You remember what I told you on the beach, the day of the crash. You remember what story I told you when you were stitching me up. (screaming) Do you remember it?
Kate: (in agony) Yes, yes, I remember!
Jack: When you get safe, you radio me and you tell me that story.
Kate: (crying) Jack, please!
Jack: If I don't get a call from you in the next hour I'm gonna know that something went wrong and he dies!
