Wouldnt it be something if smokey does take dead bodies and mimics not just one but as many as it wants. And what if when ben said about the fuselage "that there might actually be survivors", he meant something different, as lets say they all did die and smokey took over their form and thats why locke can walk and why rose is cured of cancer. Or maybe a couple died and some survived and he took form of the ones who died for what ever reason. And whats not to say dannielle the french chick is also part of smokey. They did tell us we missed something in the pilot and maybe this is what we missed, that they are dead and thats why so far all of the tailies have seemed tto get killed off, because they were actually alive. And the whole thing with others and what they are really doing is more then just needing someone for surgery, they know whats going on and are testing them to see how they react to certain things, as if smokey can really be human? i duno just a lil something, but would make a good show if that were true, damon has said that he garunteed we would not like the ending of lost and that it will be great, but tragic. so who knows.
