LOST Season 5 Episode 1 - Because You Left Overview : Jack, Kate, Hurley, Sayid, Sun and Claire's son, Aaron - otherwise known as the Oceanic 6 - have been rescued and continue to try and pick up the pieces of the lives they knew before the crash and to perpetuate the lie concocted to hide the truth of what really happened. But Jack and Ben must convince all of them to return to the island in order to save those left behind. This will prove quite a feat since Jack is still wrestling with his addictions, Kate won't speak to him, Hurley is in a mental institution, Sayid is an assassin and Sun blames Jack for Jin's death when the freighter exploded. Adding to their worries is the fact that they also have to take the body of Jeremy Bentham - aka Locke -- with them in order to make things right with the island. But locating the island may prove even more difficult since Ben moved it. It's not just a question of where it went, but when. Back on the island, the survivors who were left behind begin to play out the surprising events that inevitably lead to Locke's death. In the first part of the season premiere, entitled "Because You Left," the remaining island survivors start to feel the effects of the aftermath of moving the island, and Jack and Ben begin their quest to reunite the Oceanic 6 in order to return to the island with Locke's body in an attempt to save their former fellow castaways.   read more »
