I was just thinking about the season fianale of season 3 and im trying to think ahead of what will be happening in the 4th Season because if they are off the island then isnt that the end of lost, i dont know how the directors can drag it out for another 3 seasons them being "off" the island I was just wondering what your thoughts of what may happen in the future.... and Charlie being dead
and how claire will react to that
, also how Walt came back does that mean that him and micheal never left the island.
