Jack tells Hurley some good news in this new promo video clip for Lost season four. But he's not telling Hurley everything that's going on. It looks as though some bad stuff has already gone down at this point in episode one, and there's a psychopath on the loose. Watch the video to find out which character winds up the worse for wear.
Ben got the snot beat out of him and Naomi was killed by Locke with a knife to the back at the end of last season. So the claim that "some bad stuff has already gone down at this point in episode one" is incorrect. All the bad stuff already happened in the previous finale. This looks very early on in the first episode.
So yeah. I'm a nerd.
