I'm pretty sure after the season premiere the producers said on Kimmel that Shannon was coming back. Isn't it getting a little late for that?
And what about Walt? I thought he was going to have a major role in this season?
Rose and Bernard are interesting as well because shouldn't they have time-traveled with the other Losties if that was the case at the end of Season 5?
And are we going to see Eloise again? Or will they just make references to her in a flash-sideways/flash-back?
