John Locke is not dead. The "imposter" we all simply assumed is MIB after witnessing his confrontation with Jacob at the beginning of "The Incident". However, I believe that it is in fact none other than John Locke himself. Let me explain A LOT... this is going to be all over the place, so bear with me...
I believe that "The Incident" will indeed end up being when Juliet detonates the hydrogen bomb and the Hatch will explode again just like it did when Desmond turned the key in the season 2 finale. I believe that in the beginning of season 6, we will pick up where season 5 left off. Kate and Jack will be carrying Sawyer away from the giant hole, Sawyer will be screaming for Juliet, and Miles, Chang, Radzinsky and the rest of Dharma get far enough away from the Hatch that they are not harmed. Hurley, Jin and a dying Sayid drive up in the Dharma van and ask what happened, and Sawyer is screaming, and everyone starts fighting when suddenly, Juliet detonates the bomb and they are all caught in the explosion, and there is a huge white flash. Jack, Kate, Saywer, Jin, Hurley, and Sayid are caught and hit by the explosion along with Juliet, and the seven of them wake up in the jungle similarly to Desmond, Locke and Eko when Desmond turned they key. Basically, they were all "killed" i! n the explosion of the hydrogen bomb, and the reason Richard told Sun that "they all died" was because he was either watching from across the island or from the Hydra Island as Juliet detonates the bomb, and knows that anyone within that area was dead. However, even though they all "died" as the Hatch explodes, they are ALL still alive, ALONG with John Locke. Why? Because Jacob blessed them all with the ability to live in two realities in two different bodies. Desmond was only able to flash back and flash forward into his past and future and alter events, but he couldn't CHANGE any of it, because ultimately he was still in his ONE body, and that body was in ONE reality, even if his MIND wasn't. With Jack, Kate, Sawyer, Sayid, Locke, Sun, Jin and Hugo, they are able to not only live in two different minds, but also two different bodies so that they could actually live in two
different realities at once, literally, with the same memories in each reality. Let me EXPLAIN.
Right after Desmond blew the hatch, Locke wakes up in the middle of the jungle like Jack in the first episode of the series, and looks like he's been strangled. He cannot speak, and acts like he's been choked. He acts weird after this, and then tells Charlie he needs to speak with the Island. He then creates a tent to hallucinate in, and finds out from Boone that he must save Mr. Eko. Why does he have to save Mr. Eko? Why does Eko need John's help? Locke and Charlie rescue Eko from the polar bear, and Eko tells John that he is a hunter. Eko is then shocking killed just two episodes later. Eko was killed by an apparation of Yemi... Smokie (MIB) wanted Eko to die because he was altering his plan for Locke in a bad way and I think he realized Eko was too brave and too much of a warrior and a threat to have influincing Locke (Eko became the new Walt/Boone in season 2/3 before he died - MIB doesn't like other people influencing John for some reason it seems, anyone who gets too c! lose to him leaves the island some way.) Eko helps Locke to find a new station that ultimately leads him to The Others right before he is killed by MIB, and Locke then begins his journey of eventually becoming the leader.
Here's the part that will shock you all - The John Locke that wakes up at the beginning of season 3 and does all this - He is one of two John Lockes. The one that wakes up and can't breathe is the John Locke from the second reality - the one that had been on the island for all that time right up until Christian helped him turn the wheel in "The Life and Death of Jeremy Bentham". When Locke did this, he flashed Sawyer and Co. to 1977 - so ultimately John Locke was responsible for "The Incident", and Christian told him to do it, and claims to speak on behalf of Jacob. But why would Jacob want to cause "The Incident", and why would Ben, Eloise, Widmore, Richard, etc. constantly be trying to influence the Losties destinies? Because all of those people have somehow experienced what will happen in the future, and they are constantly looking for a way to try to change things for a better outcome, experimenting with time, space, life, etc. Jacob, Eloise and Ben wanted to cause "The ! Incident" for a reason - To create an alternate timeline perhaps? Maybe it is a big loop, maybe it isn't, but those people are clearly working together to try to cause the Incident, which they ultimately do. Perhaps one reason is to keep Widmore from finding the island, perhaps it is to keep MIB from doing something awful like destroying the entire planet or something... whatever the reason, Ben, Jacob, Eloise, Ilana, Brama, The Others - they are "the good guys" ultimately, as they are trying to prevent MIB/Widmore from destroying the planet or at least the island (Why would Keamy torch it?). I think that when Ben moves the Island and the Island skips a bunch of times until Locke stops it, I think the Island skips through time and space, and when it ends in 1977 and settles, it is still the same reality as when Desmond turned the fail-safe key, but when the Incident is caused, the universe "course corrects" and the one reality/timeline once again becomes two realities - one! in present time, and one in the past.
The reason Ben can't kill Widmore and vice versa is because they are in different realities number one, and number two, even when their realities merge in season 3, they both know bits and pieces of the future somehow, and know that killing each other would alter the future potentially, just fyi I suppose.
Also, keep in mind a key fact = that the Island's electro-magnetic powers are well documented - after "the Incident" The Island became an alternate timeline, and contanined so much electro-magnetic energy that it causes the island to continually move through time and space, which is why it can disappear and seemingly travel the world - Because of the ridiculous amount of energy the island seems to sit on, that it is in fact its own reality which cannot be accessed by the outside world unless it "chooses to", and also when the Others want to come and go. I think Magnus Hanso made the Island this way somehow, and that Alvar Hanso or whatever his name is lives in the Temple of the Others. The Island really seems to "control" the destinies of all of these characters. I think Richard and the Black Rock crashed there and Jacob made Richard immortal and his "assistant". I believe that MIB is the black smoke, and the man that was in the cabin who told Locke to help him, and I think ! that he was trapped in the cabin by Jacob, and could only leave the cabin as Smokie or other people (Yemi, Walt, Alex, maybe Claire, mayve Christian, maybe Boone, Horace Goodspeed, etc.). I think that the reason he couldn't pass the electro-thingys that zapped Mikhail in season 3 is because the electro-magnetic energy harms him and prevents him from going into certain areas. When Desmond turns the fail-safe key however, he releases all the energy, and it is gone, the Island STOPS completely and comes back into ONE REALITY, merging the TWO realities created by "The Incident". This is why Penny Widmore and her mean father are able to find the island, why the freighter is able to access the Island, why Penny rescues Desmond, Jack and Co., etc.
This is why I believe Ben wanted to create "The Incident", along with Richard, Jacob, etc. - to somehow alter the future to find some kind of loophole to stop the inevitable. Who knows, maybe Jacob and Ben, Richard, Eloise, etc. saw into the future and saw that MIB and Widmore would win if they didn't somehow find a way to re-inact the events of season one by causing "The Incident" and making the Island "implode" again and make two seperate realities again, just like before Desmond turned the fail-safe. They successfully do this when Juliet makes the bomb go off, and it literally kills all of the Losties in THAT reality. Basically, it brings them back to their other reality, since two realities now exist due to the explosion of the bomb. So YES - Jack, Kate, Saywer, Sayid, Hurley, Jin and Juliet all die in the explosion of the hydrogen bomb - and wake up just like Locke did in the beginning of season three, RIGHT after Desmond turns the fail-safe key. I think Jack's eye will! wake up just like Locke in the beginning of episode 3 of season 3, and he will be dazed from getting hit in the head with the toolbox still, and will have a Desmond-like flashback to 2004 as the plane is boarding (or somewhere around there), and he then attempts to change the future again by trying to get everyone off the plane perhaps, and he successfully gets flight 815 canceled or something, and he alters the future, but ultimately cannot change what was meant to happen, even if he succeeds in altering HOW IT HAPPENS, which is KEY because Desmond successfully ALTERED his past, but ultimately could not change destiny overall. Jack's attempts to stop flight 815 end up being pointless as what was meant to happen happens anyways. This continues to happen to Jack over and over again like it did to Desmond and he becomes sick from it. Meanwhile, Sawyer and Kate wake up in the jungle together and hear a dying Juliet. Sawyer finds her and holds her as she dies. For some reason! , she doesn't remember Sawyer or Kate right before she dies. M! eanwhile Jack will still be struggling with his flashbacks to 2004, Sawyer will be enraged, Kate freaking out, when suddenly they are found by Hurley, Jin, and Sayid, who were also caught in the Hatch explosion in 1977, and Sayid will still be slowly dying from his gunshot wound, and Hurley and Jin will be confused and frightenened, Saywer will be freaking out and Jack will be having these flashbacks, and a huge fight will ensue until John Locke approaches them and tells them that they need to get to the Orchid and turn the wheel in order to get to where they need to be. All 7 (Locke, Jack, Sawyer, Sayid, Jin, Hugo, Kate) are now duplicated because they are technically in "the past" still, right after the implosion of the hatch. Because of Jacob's touch, the 7 of them have their full memories from their "alternate-reality selves", or the ones that were technically "killed" by the bomb, so they know all about what is about to happen - If Jack calls the freighter, if Charlie goes to ! the Looking Glass, when the Others will come for the pregnant women, when Locke will kill Naomi, etc. This gives Jack and Company the chance to try to change the future a second time, but Locke warns Jack that if he tries again to change the future, he will probably only cause it, and that now there are two of all of them walking around, and that they all need to find "their right place". When Jack asks Locke what that might be, Locke tells him that they need to move the island immediately this time, that they cannot be seen by their other "selves" and that they cannot try to alter the past - only the future. Jack disagrees and is angered that his plan didn't work and his flashbacks to boarding the plane didnt change anything, and he again fueds with Locke and tells him that they need to try to stop the freighter from coming.
Jack and Locke will have a confusing, heated stand-off, as everyone else stares dumbfounded that Locke is alive. Locke tells Jack that they caused an alternate timeline when they detonated the Hydrogen Bomb and blew up the Hatch in 1977, which is why the Dharma had to then re-create the Hatch and push the button every 108 minutes to release a slight bit of built-up electromagnetivity. Locke tells him that what is done is done, and that the past CANNOT be changed, that NOTHING can be changed, and Jack angrily tells him that they can "fix" everything by intervening, and Locke angrily disagrees. Jack ultimately defies Locke, and, still having flashbacks trying to change the past, sets off towards the beach to confront the Beach Survivors (Charlie, Claire, Aaron, etc.), but Locke says that he can't do that and tackles Jack, and Jack angrily beats Locke and set off to the beach in order to try to change the past. Kate, Sawyer, Hurley, Jin, and the dying Sayid follow him to try to! stop him. Jack refuses, even after Sawyer and Kate attempt to hold him down, but then Jin realizes that Sun is there and without thinking starts running towards the beach. However, he is suddenly caught and tasered by someone. Jack and company look around, and one by one, Sawyer, Kate, Jack are all tasered and subdued along with Jin, Hurley and Sayid by none other than Richard Alpert and The Others, who bring them to The Temple forcefully, and tell them ALL about Jacob, the truth about the island, the time travel, everything, and Richard warns Jack about what will happen if he tries to alter the past again, and that MIB and Locke will end up destroying the island in 3 years and unless they do exactly as Jacob says, they will succeed. Claire is in the Temple along with Christian, and the Shepherd family is reunited. Zach, Emma, Walt, The Flight Attendant, and many of the other 815 survivors are there also. Christian tells Jack that he must now lead more than ever, and that ! him, Kate, Sawyer, Jin, Hugo, and Sayid must not leave the Tem! ple for the next 3 years until Jacob's plan works and Ben stabs Jacob. At this point, Richard tells them that Jacob will become the white smoke monster and will attempt the rid the island of MIB forever, and that he cannot do it without Jack and company. So Jack and company stay in the Temple throughout the next 3 years, carrying out orders and waiting. I think Sayid will be fixed by Richard in the Temple, just like young Ben was.
Meanwhile, Locke makes his way to the Orchid Station, planning to attempt to get to the time period and reality in which he belongs. As he goes however, he is confronted by The Black Smoke again, but instead of beauty, this time Locke sees pure anger and rage and sadness, and is consumed by it and, falls victim to MIB - He isn't killed by the monster, but simply teams up with it, almost letting MIB possess him in some sort of way. I think MIB tried to possess Eko and couldn't control him and thus killed him because he was a threat. He then turned to Locke and after all of this time, successfully convinces him to help him kill Jacob (because Locke believed that whatever happened happened, and by Jack trying once again to "change" and "improve" things, he would just make things worse. MIB successfully convinces him to kill Jacob, and tells him how he will be able to find the "loophole." However, Ben and Jacob, who are in 2007 in the other reality, know about Locke and MIB's pl! ans even before Ajira crashes on the island, and they know the only way to stop them from succeeding in their evil plan (Which is why Widmore wanted Locke well taken care of and told him when the war on the island arrived, he NEEDED to be there). However, Ben and Jacob trick Locke because Jacob wanted Ben to stab him - Jacob becomes the white smoke monster, that is my guess. Jacob leads Ben, Ilana, Bram, and The Others, along with the Ajira survivors, against an impending attack by MIB and his "forces" whatever they may be. Jacob tells Locke that "they're coming", referring to all of the people in The Temple, which Locke for some reason seemed surprised and scared about right before he kicks Jacob into the fire.
I think that after Locke kills Jacob, Jacob becomes the white smoke monster and leaves the Big Foot. Ben and Locke emerge from the Foot as well, and are greeted by Sun, Lapidus, Richard, Ilana, Bram, the other Ajira survivors and Others, and Locke from the second reality's dead body. There is great confusion over the two Lockes, and there is a bit of a standoff. Locke gets into a fight with Richard but the smoke monster suddenly appears and starts to wreck havoc on everyone. Locke realizes what he's done and somehow gets away. Everyone from The Temple suddenly appears, and large battle ensues. Jacob's team vs. MIBs team, black vs. white. I think Widmore will somehow become involved for the "bad side", and that Desmond will also be involved somehow, but with the good guys. I also think Walt will have a huge role, and a big revelation is that he has been inside the Temple all along, since being captured by The Others in Season One. I think Charlie, Michael, Boone, Shannon, Eko! , Ana Lucia, Libby, Nikki, Paulo, Charlotte, Faraday, Naomi, Rousseau, Alex, Karl, Pickett, Tom, Mikhail, Abbaddon, Arzt and everyone else who has died will still be dead at this point - DEAD IS DEAD. I also believe that Rose and Bernard will live on the Island after "The Incident" and they will die sometime in the future and become "Adam and Eve" from the caves. I think that Miles ends up leaving 1977 and flashing to 2007 in a different way - by turning the wheel again perhaps? I believe he ends up in 2007 with everyone else and will be one of the good guys in the war. I think that ultimately, the good side will win, and that both MIB and Jacob end up dying for good somehow, along with their "smoke monster selves". I think that in the end, Locke will change his mind and realize that switching sides and letting MIB manipulate and use him was the wrong thing to do. He ends up betraying MIB and saving the Island, and everyones lives by teaming up with Jacob and Jacob's team (! Jack, Kate, Sawyer, Sayid, Sun, Jin, Hurley, Miles, Ilana, Bra! m, Ben, Richard, Walt, Claire, Lapidus, etc.). Jack and Locke end up working together to defeat MIB once and for all, with Jacob also being killed in the process - Jacob and MIB are like a yingyang, one cannot exist without the Other. I still think that before this ends up happening, many characters will be killed in the final "battle" or whatever. I think that in the very end, Jack will end up making the ultimate sacrifice by dying so that MIB will die and he will become the ultimate martyr and hero of LOST. In the end, Locke will convince him that whatever happened happened, and that they can only try to make the future better now, and Jack agrees and ends up killing himself in order to kill MIB. I also believe that Richard will turn out to be bad - because as is LOST, everything is almost always not what it seems. Richard has been shown to be a nice, caring guy, and everyone likes him, he gets barely any screen time but was such a fan favorite that he was made into a main charact! er for the final season. He will end up being evil and working for MIB, and will kill a very main character as a stunning betrayl - I bet he kills Ben in the series finale, and is then killed somehow when Jack dies, along with MIB and Jacob. Last but not least, I predict a tragic death for Sayid, but not at the beginning of season 6 - he will be fixed at the Temple and live until 2007 but will die towards the very end of the series to save someone else from being killed, let's say Sawyer. In his dying breaths, he says an Islamic Prayer and tells Nadia that he is coming for her. So I predict that Jacob, MIB, Ben, Widmore, Sayid, Richard, Christian and JACK will all die in season 6. I do NOT think Locke will die. It will be the complete opposite of whats expected, which is classic LOST fashion.
I think that after the battle is finally over, Sawyer, Kate, Hugo, Jin, Sun, Claire, Walt, Desmond, Miles, Zach, Emma, The flight attendant, Lapidus, and all of the other Ajira and 815 survivors will end up leaving the island for good... Sawyer and Kate end up together and Sawyer finds Clementine, Claire returns and is re-united with Aaron, Jin and Sun go home to Korea and live a luxurious life with their child, Desmond, Penny and Charlie end up happily ever after, Walt will end up re-uniting with Vincent somehow and they will go back to NYC together, Hurley will move back in with his parents and chill with Cheech and give Walt a bunch of money from his bacgammon losses, Miles goes back to whatever it is he does, Zach Emma and all the other crash survivors go back to their lives respectivlely. Last but not least is John Locke, who stays behind on the Island along with Bram, Ilana, and what is left of The Others, and finally becomes their true leader and watches over the isla! nd and protects it for the rest of his life happily.
This is my prediction on how LOST will end in season 6. Comments are welcome.
