Article : Tv guide scoop on Jack

What's in store for Jack on Lost? — Edison
MICKEY: Matthew Fox tells us that Dr. Shephard is not so interested in saving people anymore. "For the first time in his life, he's really listening to his own sense of what his fate is. He actually believes he's completely ready to give his life for what he is meant to do on this island." Gulp. That sounds ominous, huh?
