Desmond centric epsiode, I have a feeling we are going to see ALOT of info in this episode as it seems Desmond is central to a lot on this island.
However I think I'll probably watch it at home without commercials 15mins delayed
I still think that they will have to make a choice as to which reality will be the real one.
Desmond appears to be the only one that can "see" both realities at the same time by using that machine from last night to tune in the other reality. Perhaps the others can see via near death experiences. Is it better for Charlie to have loved and died vs living his unhappy rock star life? It is hard to say which reality is really better right now.
