Continuity mistake: Season 4 - The Beginning of the End - Hurley is swimming in the ocean. He sees Desmond return with the boat, and by the time he gets out of the ocean and walks over to Desmond and yells, "Where's Charlie?" his shirt is dry with sweat stains on it.
Question: I recently submitted a question about whether everyone died on the plane or on the island. The answer I got was unsatisfactory. The answer was they did not all die in the plane crash but on the island where the events in the show really did happen. If this is the case, everyone in purgatory at the end makes no sense. If they all died on the island, then where were other characters like Michael, Ecko, etc. Also how did Kate, Sawyer, Hurley, Ben, etc. end up dead and in purgatory at the end of the series? Last we saw them they were still alive on the island. Are we to assume that everyone died at the end of last season when the bomb went off? I need more info here.
