Flashforwards

We return to the final scene from last year's finale with Jack at the airport screaming to Kate that they have to go back to the island as she drives off. We now see Kate brake hard, return to Jack -- he thinks she's changed her mind -- but she tells him he's lost it and to stay away from her and Aaron. She also makes a reference to a mysterious "he" -- the person in the obit that Jack showed her. She says "he" came to see her and said the same thing to her that he said to Jack, but that she isn't buying it...

 

Sayid visits Hurley in the asylum, asks if the mysterious "he" has visited him. And that "he" is now dead.

 

Island Story

Alpert and the Others (with Kate and Sayid) attack Keamy, liberating Ben.

 

On the freighter, they realize the bomb is tied to the device that Keamy is carrying. If he dies, the bomb blows. But Michael uses some kind of freezing liquid to slow down the process so the bomb doesn't immediately trigger.

 

Jack makes it to the Orchid. He and Locke have another of their debates about whether everyone should leave the island or not. Locke convinces Jack that if he wants to leave, he has to lie about the island back at civilization. It's the only way to protect the island and survivors...

 

Ben kills Keamy in revenge for killing his daughter (Keamy followed Ben and Locke down the elevator to the Orchid).

 

On the chopper, Jack, Sawyer, Kate and Hurley lift off with Lapidus piloting. But the chopper is damaged and can't carry them all. Sawyer gives Kate a farewell kiss and jumps out(saftly) so the others can make it to the freighter. This is the talked about kiss. It's hardly earth-shattering.

 

In the Orchid, Ben explains to Locke some crazy idea that the island can move t only in space but also in time. Apparently there's some kind of giant wheel hich is entombed in oce thatan move the island.

 

The chopper makes it  to the frieghter, picks up Sun and Aaron. The bomb goes off, killing Michael. Jin is thrown into the water -- looks like he might be dead, but I doubt it. I'll bet Jin will be back next season. Anyway, Jack refuses to go back for Jin because he thinks the chopper is too heavy and that's why Sun is pissed at him.

 

Back at the Orchid, Ben knows that my turning the frozen wheel, he'll also teleport somewere else -- (and by the parka he puts on, we know he'll teleport to the desert, as shown in a previous ep).

 

Ben chips away at the ice around the frozen wheel and manages to turn it so that.. yep, the island moves. I kept hoping right up to this point that it was a fake-out and that Ben had some other plan. But no, the island (and even the surrounding islands) all move.

 

Anyway, ths last flashforward is a continuation of the scene from last year's finale where Jack is in the funeral parlor in front of the coffin. Ben approaches him -- he's been following him -- and Jack tells him that "he" told him has to go back to the island.

 

Then Ben tells him that they have to take "him" back too. They look down to the coffin and inside we see the dead body of .. Locke.

 

Locke is the "he" that all the flashforwards have been referencing. Somehow he must've made it back to civilization, but got killed.

 

The plan must be to return Locke to the island and somehow ressurrect him -- an idea that's up there with the frozen wheel and moving the island.
