The explosion has somehow allowed Desmond to travel back in time and he is now able to see flashes of the future. This is a superpower that none of "The Others" could have imagined happening out of the blue, but perhaps they have been conducting experiments on some of their captured victims to see if this is possible.

If they find out that he can see the future and is able to change it, he would undoubtedly catapult to the top of their list. But will they want to eliminate him or use his powers for their own purposes?

If they attempt to capture and control him they will be playing a deadly game for a man who can see the future may know his enemy's every move before they even think of it.
