Here we go:
•The Island was real. Everything that happened on the Island was real.
•The final image of the plane crash was just there to show how far all the characters had come over the course of six seasons. (I feel good about this, because that's what I've been telling people on FB, without any verification.)
•The purpose of the island is to keep good and evil balanced in the world. That has always been its purpose, and always will be.
•The Island has always had a Protector, even before Jacob, even after Hurley. •Jacob was, however, unique as a Protector because he had the Man in Black working against him; the devil, as it were. Jacob needed to kill the MIB but the Rules of the Island kept him from doing so.
•Jacob brought the candidates to the Island to kill the MIB. He had brought other candidates to the Island before Oceanic 815, but the MIB always got to them first and corrupted them. Richard Alpert was the one who made Jacob see he had to get more actively involved if he wanted his plan to work.
•Jacob brought the Dharma Initiative to the Island as part of his big plan. The original intention was for the Dharma Initiative to work for good. However, the MIB messed up this plan by corrupting Ben Linus. The MIB made Ben think he was doing Jacob's work when he was really serving the MIB.
•The Others and Ben killed off the Dharma Initiative and later tried to kill all the candidates from Oceanic 815 because that's what the MIB wanted. Apparently the same Rules that kept Jacob from killing the MIB also kept the MIB from killing Jacob's candidates.
•Jacob wanted to give his candidates something he had never been given: free will. (And his brother, the MIB, also had never had free will.) This is why he let the candidates choose who would have the job of killing off Smokey/the MIB in the end. This was always the key question of the show: Free will vs. predestination. (With the second dichotomy being science vs. faith.)
•No one will officially say whether Jack needed all six seasons to get to the point where he could kill Smokey/Fake Locke. But some people think this is the case.
•Jack was happy at the end because he did what he always wanted to do: Save his fellow castaways, get them off the Island.
•We all have people in our lives who are with at the "most important moments," as Christian Shepherd says at the end. Think of them as your reincarnation buddies -- the people you move from one lifetime to another with. The castaways on LOST had this sort of "soulmate" relationship with one another.
•The Sideways world was a version of purgatory, subconsciously created by the castaways as a sort of "holding place" where they would exist until they could find each other and move forward to the afterlife. It's not "Live together, die alone," as Jack said in season 1. It's "Live together, die together."
•The castaways were meant to be on Oceanic 815 together. And it wasn't just because Jacob wanted it or predestined it, but because it was meant to be in a more cosmic sense.
•In the science vs. faith dichotomy of the show, the writers chose to come down on the side of faith, which is ultimately the answer to all the mysteries.
•Michael wasn't allowed into the Sideways/"purgatory" world because he failed his test on the Island, and was not worthy to move on. Same with the MIB.
•Those we saw in the church did pass their tests and were allowed into the Sideways world when they died. Some died prior to Jack's death, some died after Jack's death. Hurley possibly died centuries after Jack's death.
•Those who were in the Sideways world but were not in the church -- Anna Lucia, Faraday, Danielle, Alex, Miles, Frank, etc. -- have to find their own "soul cluster" [to use a phrase Doc Jenson is using on ew.com] before they can awaken and move on.
•Ben didn't go into the church and isn't ready to move because he hasn't yet connected with the people he must connect with. He needs to awaken Danielle, Alex, and others. And he has to atone more for all the harm he did, more than just being Hurley's #2 on the Island. He has to become what Hurley and Desmond were: The connector that helps the others in his "soul cluster" to connect with each other. When everyone else in his "cluster" is ready, he will get to move on, too.
•Same is true for the others we didn't see in the church: Daniel, Charlotte, Eloise, etc.
•Ben is also not in the church because the final church scene was written immediately after the pilot was written. When the writers said they knew the ending from the very beginning of the series, this is what they meant. They did not change what J.J. Abrams originally wrote. Ben was therefore not included, because his character was meant to have a tiny 3-episode arc and be out. However, they loved the actor, and kept him in the show.
•The original ending starts at the moment when Jack walks in and sees the casket and ends when he sees the Ajira plane fly overhead and closes his eyes.
....Okay, this answers a few questions for me, and helps me understand why I didn't necessarily catch everything in the finale. I'll weigh in with my own thoughts on the finale very soon....
