I Don't think anyone has posted anything like this yet , but my apologies in advance if I am repeating anything here . This is my Theory as to how Lost will end . The reason everyone that was on the plane must return to the Island is B/C someone( Locke , Desmond ?) has figured out the time travel thing and once they get everyone back in one place they will trigger it to become moments before the crash happened and somehow prevent the crash . The plane will safely land at its final destination with ALL the passengers alive and well . Now I know A LOT of thought and technical stuff has gone into all these discussions , but think about the simple references to Alice in Wonderland and The Wizard of OZ . Everything ends at the beginning so to speak .... I've thought a lot about all this and I am convinced it will END THIS WAY !!! Maybe not Happily Ever After , but if they remember it all , they will all be BETTER PEOPLE with a good start in the right direction wouldn't you say ?
