“I've seen this Island do miraculous things. I've seen it heal the sick, but never once has it done anything like this. Dead is dead. You don't get to come back from that, not even here. So the fact that John Locke is walking around this Island... scares the living hell out of me.”
— Brian K. Vaughan, Elizabeth Sarnoff, Benjamin Linus, Michael Emerson, imdb.com
