They wanted to kill off Jack in the Pilot episode, because it would have come out of left field. I think they will kill him off in the finale and blow all of our minds away. Richard will then take his new place as Jacob. Who knows how to do Jacobs job better?
This would crack me up for days and days. Not because I don't like Jack, but because it's sort of an inside joke with me and my friends and coworkers that if they say they missed last night's episode of LOST, I just blurt out that Jack died to see the reaction on their face. Now I HAVE to say it, because if he does die, and I don't say anything, everyone will know that Jack actualluy died. Oh, what a wicked web we weave, when first we yadda schmiggildy flop.
Miles can see how people died, Hurley can talk to them after they're dead, and Desmond is the "constant" (time-travelling experiences, immune to electromagnetism - whatever). Walt has a special power as well,
Worst group of Superheros ever!
HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA
...Juliet gets revealed as Jack's ex-wife in the sideways (so the producers can leave the show with a nice send-off to try and get people to watch V)
HEY!! I watch V, what's wrong with V?? LOL. I mean it's got Inara (from Firefly) as the head baddie, and the first few episodes had Wash (also Firefly Alum). The next thing you're going to say is that you don't like Castle.
