something just came to me that i never thought of. it may have been said before. but if i havent seen it its new to me.
ok, desmond became gifted after and encounter with the islands energy. jacob and his enemy seem to be pretty gifted themselves. maybe they attained there powers in a similar way.
that said is it possible that now (as of the incident) jack and the other losties have themselves become blessed with some kind of power. that would be interesting.
