For those of you who can remember....give me your thoughts please..In the constant from last season, if you remember, after the blast of dharma station manned by desmond, desmond fell into a time loop and was going back and forth between the past present and future.....as the viewer experienced it....desmond was physically present on the beach, but was obviously having some kind of extraordinary experience....to the point where he could predict that charlie would die in the underwater station.....
Then comes daniel in "the constant" and he realizes what desmond is going through....and realizes that he had met desmond in passing at oxford....Daniel knows that if you get stuck in the time loop you will die...solution find a constant...desmonds constant was penny...
So the question now is What is the constant for the losties? I think the losties(on the island) are experiencing the same thing that desmond was experiencing except we are seeing it from a different perspective...
