Josh Holloway says you'll see a new side of Sawyer this season — a more take-charge, leader-y side, and he also gets to be more heroic in the wake of his selfless plunge into the ocean last season.
Meanwhile, Michael Emerson says the island did travel in time (duh) and after Ben turned that wheel, he appeared in the desert two years later, as we saw in an earlier episode. And Emerson says he would "make myself nuts" if he tried to get a handle on all the moments in the past, present and future of his character. "I'm not even sure how many continents I have visited this season." And the reason why the Oceanic Six have to return to the island has to do with something Ben did, which "went really wrong." Also, Emerson thinks Ben may die, but he'll also survive to the end of the series. (He could both die and last until the show's end, thanks to all the time-flipping.)
