Michael’s been gone for two episodes now, and is trying to find Walt. I’ve been hoping that Walt will be back soon, because we might get a better idea of what The Others have been thinking when they tried to grab Walt.
We saw the bearded man (the guy Sawyer called “Zeke”, and that the producers call “Mr. Friendly”), ask Alex to bring Kate to him. Could Walt have met Alex? Might Alex try and leave with Walt to go back to the LOST camp? That sure would make Danielle a larger part of the show.
