Lost returns for its final season of action-packed mystery and adventure - that will continue to bring out the very best and the very worst in the people who are lost- and the viewers, who are at the end of their tether at this stage. however, before the final season opener (at 9.00pm), we're being treated to a handy recap - as has become customary. There's no way you'd keep track of the mindless tangents otherwise. For example, observe the press release for tonight's episode: With only 18 original hours left until the final episode airs, the island's violent shifts through time were ended by Locke when he traveled 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? Lost?
