I am not sure if anyone has written about this, but this could be a little time loop fun. When Locke is going down into the well he is using the rope. Sawyer begins to hold on to the rope as the time flash begins. After the flash, the rope is sticking out of the ground where the well will probably be one day. Do you think that the rope sticking out of the ground was the very thing that someone used to find the location of the frozen donkey wheel?
