Who were the bodies in the cave? (can't remember whether or not they really answered that) What happened to Bernard and Rose? The Dharma initiative: Why? What do Widmore and Eloise have to do with/what were they doing on the island? Do any of the original main characters actually matter anymore?
1. They haven't said who the bodies in the cave are, although early favorites Rose and Bernard (because of the "Only fools are enslaved by time and space"/"Bones of Nadlers may lay lost deep in cave" anagram) seem to be crossed off because of their "retirement." The Locke-Dressed Monster said one of the only three ways out of the game is to just leave, so Rose and Bernard have just left.
Recently, I thought it might be Jacob and Smokey, somehow, but with Jacob getting killed by Ben that seems unlikely.
I thought it might be Kate and Sawyer for a long time, because those are two of the most irredeemable characters. Sawyer murders people left and right without compunction, and Kate killed her step-father in one dimension and an innocent plumber in the other. So it makes sense from a narrative standpoint that they redeem themselves by sacrificing themselves for their friends.
But with Tuesday's ep having Widmore tell Desmond he's going to demand a sacrifice to put things right, I'm thinking it's Desmond and Penny and True Love in the cave.
2. Bernard and Rose are just sitting it out in their Gilligan's Island tropical retreat. I loved that ep where we see them again at the end of Season Five and Bernard has a long beard and is all serene and whatnot and Rose says "What
is it with you people?" That just made me laugh.
3. Saying "The Dharma initiative -- why?" is like saying "The Jem Ha'dar -- why?" about
Deep Space Nine or "Principal Rooney -- why?" about
Ferris Bueller's Day Off. Your main characters need someone or something to struggle against; otherwise it's just pretty sweaty people smooching each other in polar bear cages. Which has its appeal, sure, but won't make the show last six years. I really enjoyed the Dharma/Others/other-Others-in-the-Temple/Team Jacob/Team Smokey dynamic as it evolved over the six seasons.
4. Both Widmore and Eloise were leaders of The Others in the late 70s; the Others being a faction that witnesses the game between Jacob and the Smoke Monster.
5. I think the six candidates: Jack, Hurley, Sawyer, Jin, Sayid, and Locke (with the last two obviously not being candidates to replace Jacob anymore, but, still) matter quite a bit to what's going on here at the end. Fact is, I think Mrs. Hawking is not just Eloise, though, mother of Daniel and former leader of the Others. I think Mrs. Hawking, who met Desmond in “Flashes Before Your Eyes,” the one that was guiding everyone at the Lamp Post Station, and the one giving Desmond a hard time in Dimension X, is really a manifestation of the Island. I won’t go all the way to saying the Island is Locke’s crazy mother, but weirder stuff than that has happened on this show.
I think the end is going to be Jack and Fake Locke sitting on the beach in the future watching a hovercraft or something full of people in 2019 coming towards the Island and Locke saying, "Do you know how much I want to kill you right now?" and Jack(ob) saying, "You know the rules." as the game continues.
