Lost: Series 6

With only 18 episodes remaining of this epic adventure, the island's violent shifts through time were ended by Locke when he travelled off-island in an attempt to persuade the Oceanic 6 to return. Back on the island, the survivors' stay in late '70s Dharmaville was over when their covers were blown and they were accused of aiding "The Others," and Sayid was gravely wounded during their flight. In addition, Ben killed Jacob at Locke's request. But since Locke's body was found to still be inside the coffin, exactly who - or what - is John Locke? And if Juliet was successful in detonating the hydrogen bomb, was she able to reset time, allowing Oceanic Air 815 to land safely in Los Angeles, or was the island destroyed along with all of its inhabitants?
