so i think you're all wrong....jack said, and i quote "I'M SICK.........OF LYING." i think that these flash-forwards are telling us more important things, more along the lines of whoever is on the "boat" telling whoever gets to go back to the real world (since we dont know who will be seen in flash-forwards yet, i can only speculate) what "really" happened to them, and to really not mention anything about the island OR ELSE. just my opinion.
