Jack dies
Jack's been the one regrettably constant thing in the whole show, and even confirmed a few years ago to be the only cast member who knows the final scenes of Lost. This pretty much means that he survives right through to the end, right? You can knock off Widmore, Alpert, the Kwons and probably many other principle cast members in these final weeks, but he's the one thing that'll be there at the end. Probably sitting on a beach. Or going on about his fucking tattoos again. But we also know that the show's creators initially intended him to be killed in the Pilot episode. They wanted to fool the audience, a la Psycho, into believeing that one person was going to be the main protagonist, only to have them bumped off. Kate was going to be the main character, and the show would have been a great milestone for women's roles in huge ensemble casts, or something. Instead, we got five years of some rubbish doctor obsessed with bossing people around.
So, maybe they're now thinking of pulling a similar trick, just one hour from the shows end? We've just seen him take on the role of being the new Jacob, something I'd thought they'd hold on for until the last twenty minutes of the finale. His journey is all complete. They can't have him just weaving and cooking fish on a beach for two hours, so what's going to happen? I think he'll get killed off very early on in the finale, and that the Jack who knows the final few scenes of Lost is in fact the one from the alternative timeline.
The Alternative Timeline takes place after the Original one
That cut on Jack's neck has been getting more prominent on both Original Jack and Alternative Jack for the past few weeks. Was it caused by something we've seen, or is it from an event we're yet to see? If it's just a cut Original Jack accumulated during one of his many recent scraps, then the following theory holds true. The Alternative timeline is going to be the result of what happens at the end of The End. That's why Jack wakes up with a slowly healing cut on his neck, and why his hair is considerably longer than on the original Oceanic flight. Something happens on island in the Original Timeline, and their existence is competely erased. Or, like when Juliet said from beyond the grave "It worked!", perhaps this is just where the characters go when they die.
One thing that doesn't fit with this theory is what the whole purpose of the concert is, with Desmond going round getting the band back together. It can't be just to tell them all that not too long ago they were living on a desert island and that they're all really great friends. The timeline is defintely going somewhere in the finale, which brings me to another theory.
The timelines meet, and only one version can survive
Everyone goes to the awesome concert in Dr Chang's museum, as Desmond had planned. He makes some big announcement, taking the stage. "You all know each other, brothers" or something. Everyone finds out they lived together for a few years being terrified on a magical island, and gets a glimpse of the other person they could be. For pretty much everyone though, these other lives do not sound too enticing a prospect. The Kwons are dead, as is Charlie, Sayid, Charlotte, Farraday, Widmore, Ana Lucia, Libby, Boone, Shannon, Michael. Pretty much everyone is either dead, miserable or currently enahbited by a two thousand year old spirit in the Original timeline, so why would anyone want to move there? Well maybe it's the other way around. Maybe the on-island timeline is now an impossible future, and everyone has to leave. Sawyer gets to be a cop, Hurley gets his girl, as does Hurley. Ben is a decent man, and Locke gets to live again. The only ones who wouldn't immediately jump across are Kate and Jack, and once again the reasons for that are to do with parenting.
Yes, as I said three years ago in the New York Post, this show is all about the absent fathers. And I think it's going to be the decision Jack has to make as to whether to stay and protect the island, or move across and be a father to his child, which will be the end of the whole show. Similarly, as Jacob pointed out in this weeks episode, Kate is now mother to Mad Claire's Aaraon. She's not going to jump at the chance to be a con on the run again.
Flocke/the Man in Black rocks up in the Alternative Timeline
I really liked The Lost World, as I'm a sucker for T-Rex's marauding down the streets of Middle America. I'd be really disappointed if we didn't get to see old Smokey transfer across to the real world and go rip up some strip malls before the show finishes. He's been talking about it for half this season, and despite it sounding like signalling the end of life as we know it, I'd quite like to watch that happen. I assume he'll turn up in the Alternative Timeline, because otherwise we really have no investment in the world he's pillaging. Besides, other than Widmore turning up from there a few episodes ago, we have no evidence to suggest that since the bomb went off the Real World exists in the Original Timeline. Anyway, here are some ideas as to how he'll turn up.
Jack's Dad's coffin will turn up at the concert. Inside will be his corpse, possessed by the the Smoke Monster.
Locke will go into emergency surgery. The person who comes out is Flocke.
Other things that we are going to see which will be exciting
We'll find out that Juliet is Jack's ex-wife and the mother of his child. She's the one ex-cast member who's been conspicuously absent from the Alternative Timeline so far.
We'll finally get to see who those people that chased Sawyer, Juliet et all on the outrigger during all that time-traveling nonsense in season five were. Remember that Sawyer shot and seemed to kill one of them? My bet is that he killed either Ben, Miles or himself. How very clever.
Someone will get made into another smoke monster, to replace Flocke. My bet is on Ben, but it could be Sawyer, who'd pull off the 'Do you have any idea how much I want to kill you'? beach chats a lot better.
Lots of people will die. There will be emotional fairwells, sacrifices and general melodrama. Lost is silly, but it's very good at this part of the bullshit.
There'll be some really bad CGI. Some kind of Time Gate through which people transferring timelines have to walk. Or another horribly rendered sub.
The end scene of the whole show will be Jack as Jacob, going around trying to recruit Kwon jr, Aaron and Sawyer's daughter as new candidates.
That's it folks. Now I'm going to switch off the internet until Wednesday so as to keep 100% spoiler free.
Namaste. And good luck.
