In the beginning we see Jack waking up...hearing Hurley's calls for help, jumping into the water to save him--and then rushing over to Kate.
Later in the episode...we see the same scene play out again--but it doesn't happen the same. Did anyone else catch that? The diologue is different. I suggest you go back and watch it again if you didn't catch it the first time around.
I'm watching it again right now--so I'll type it out for you guys.
First Time:
Hurley: "Help, anyone! *other calls for help*Jack, help!"
(Jack runs through jungle, jumps off cliff into water)
Jack: "It's okay, it's okay....you can stand."
Hurley: "Oh--Oh my god, it really happened."
(Camera pans to Kate lying on the rocks.)
Jack: "Kate. (Jack swims over to her) Kate, Kate can you hear me?"
(Kate opens her eyes)
Kate: "Jack?"
Jack: "Are you okay?"
Kate: "Are we?"
Jack: "Yeah. We're back."
Kate: "What happened?"
--------------------------------------------------------------------------
Second time:
Hurley: "Help! Anyone, help!"
(The scene cuts to Jack jumping into the water)
Hurley: "Oh---"
(Camera pans to Kate lying on the rocks.)
Jack: "Kate. (swims over to her) Kate?"
(Kate opens her eyes)
Kate: "What happened?"
Jack: "Can you get up?"
...conversation continues as we see the rest of the scene.
-----------------------------------------------------------
Now, before some of you say--"The scene was just cut down to save time, and as not to repeat everything we saw at the beginning of the episode".....
I ask you.....
Watch again...watch the scene at the beginning, and the one toward the end a couple of times.
I do realize that it is cut down. We don't see Jack running through the jungle the second time. I would explain more about where to pay attention--but you all are smart; I don't think I need to do that!

Anyway, let me know what you think!!!
i thnk this is a clever use of telling the story but not releaseing secrets.... just liek the opening scene in EXPOSE episode... doesnt happenthe way it did later.. the blurr some things for the later surprise
also in charlies death f;ash with the arrow doesnt happen the same either... only once were kyptronite sleippers were mentioned. i think its just clever uses of story telling.
