I wonder if the hiring of an actor to “play Jacob”, like the filming of multiple versions of the final scene from last season’s finale, is a ruse, and Jacob is in fact going to turn out to be someone we know well: Jack Shepherd. I wouldn’t bet money on it, not by a long shot, but I can certainly see how such a plot development would make sense.
If Jack succeeds in detonating a bomb and preventing the incident that leads to the button and leads to the plane crash and so on, then flight 815 never crashes, Jack never ends up on the island, never gets sent back to the island – and so who detonates the bomb? It would make sense to have Jack end up trapped outside of time and space, caught in a paradox of his own creation, as “Jacob”. For all we know, Jack is his nickname and his birth certificate in fact says “Jacob”.
Even if that isn’t what happens in the final season of LOST, I don’t think there is any chance that, if Jack’s execution of Faraday’s plan is successful, then we’ll simply find them landing in LA as they originally planned. History will have been changed, perhaps radically so, and thus we might have to follow the series characters’ lives into a history very different from the one we and they have known thus far.
Those looking to disentangle some of what’s going on, or just entertainment, should check out the latest LOST Untangled:
