Amazing double episode, and I have to say that it is the best of the whole season of Lost. I am not so sure about what happened to the island, I mean, who it could be possible.... they moved the entire island to another place to make this unfounded!, it is amazing!
The best part of this, of course, as always is the end of the episode, that make us wonder what is gonna happen next season. Are the six of oceanic came back to the island?, could they find it at all?, what is doing Jack´s father alives,what bag things happens to the rest of the people in the island, and the big question to me, why is Lock dead? I can´t wait to see next season.
