Lindelof & Cuse: The growth of Malcolm David Kelly (Walt) will be addressed in the 3rd season. You can expect to see more of Rousseau next year, but the story of the wrecked research vessel, it will be coming at some point but we can't guarantee it'll be in Season 3. We'll be introducing new characters in Season 3, so you'll be getting fresh flashbacks. You'll probably see fewer flashbacks of our original characters as we begin to move toward certain inevitabilities. You will learn more about some of the other survivors next year. Also, where the new characters come from in Season 3 is going be part of the fun and anticipation over the summer, and hopefully by the end of the finale you'll be getting some sense of who those characters might be. We are going to produce the next 22 hours of Lost in Season 3.
