There's No Place Like Home Part 1:
The stuff on the island is mostly people moving from place to place. It seems most of them are going to end up at the same place, though: another Dharma station called the Orchid. Ben claims it holds the secret to moving the island. Keamy is headed there for reasons unknown. Jack is headed there to stop Keamy. Sayid shows up with his raft and ferries Jin, Sun, Aaron and some redshirts to the freighter. After they arrive, they discover that there's enough C4 to blow them all up real nice on that boat, and it's set to blow. Kate and Sayid get caught by the Others, who probably want their help rescuing Ben. Ben tells Locke how to get into the station and the surrenders himself to Keamy.
The flash forward show the Oceanic 6 as they first arrive back in civilization. They all have to lie about what has happened to them, and all are uneasy about it. Those that sill have families have reunions with them, and they try to settle back in to normal life. Life is anything but normal, though. At Hurley's birthday, his father gives him the Camaro they were working on. Hurley freaks out when he sees the numbers on the odometer, though. He's not free of them yet. Jack finally buries his father, but receives a surprise at the funeral. Claire's mother is there, and tells Jack of their relations. Sun takes a level in badass, and uses her settlement money to buy her father's company. I pumped my fist in the air when I saw that one.
Mostly setup for part two, of course. I can't really hold that against this episode though, as it is an arc based show, and part two was epic. Speaking of which:
There's No Place Like Home Part 2:
We starts at the end of the flashback the ended the third season. Jack is yelling that they have to go back, and Kate is furious at him for suggesting it. We learn the name of the person in the casket: Jeremy Bentham. Who the hell is that?
On the island, Jack, Locke, and Hurley converge at the Orchid. Locke can't figure out how to open it, though, despite Ben's directions.At the the helicopter, Kate, Sayid, and the Others ambush Keamy and his men. Richard shoots Keamy several times, and it looks like that's it for him. Ben honors the agreement that was made, and Kate and Sayid will be allowed to leave the island. After this, Ben heads back to the Orchid. Locke and Jack are having the usual faith vs. science debate. Locke tells Jack that he will have to lie in order to protect the island, since it is a place where miracle occur. Jack doesn't believe him. Locke and Ben descend down into the Orchid, while Jack and Hurley head back to the helicopter.
Down in the Orchid, Locke watches an orientation video explaining that this station is for conducting experiments in space time. Huh. The doctor also warns to never load the chamber with metallic objects, which is exactly what Ben is doing. They are delayed by Keamy doing his Mikhail impression. Locke distracts him long enough for Ben to stab him several times. Too bad that the box on his arm is the trigger for the C4 on the boat. Ben doesn't seem to care too much that he's just doomed a whole lot of innocent people to death, though.
The people that were out in the jungle load up on the helicopter, and set out for the freighter. It looks like they took a bullet in the fight and are losing fuel quickly. They try to lighten the load a bit, but it's not enough to make it to the freighter. Sawyer has to go and be a heroic bastard, and throws himself out of the copter. Not before he makes Kate promise to do something for him, though. With the lighter load, the copter is able to make it to the freighter, which unbeknown to them is really the last place they want to be right now.
Well, the bomb is about to go off, so Desmond tries to warn them away. It doesn't matter, though. They have no fuel. They have to fuel up quickly and get off. Sun and Desmond climb aboard the copter, but Jin doesn't make it. Michael is also left behind, and sees Christian. Christian tells him that he can go now. The boat explodes taking everyone with it. Well crap. I'm still going to guess that Jin made it somehow. We didn't actually see him die. Michael is most certainly toast, though. Um....literally. Hey, here are our Oceanic 6. Looks like the copter crew will be the only ones to make it for some reason.
Down in the Orchid, Ben blows the back wall out of the chamber, and tells Locke that this is where they part ways. Locke is to become the new leader of the Others, while Ben will be exiled from the island for moving it. Locke and Ben each go off to meet their destinies. Ben climbs down deeper into the hole, and reaches a crank on the wall. After breaking through the ice, he turns it, and blinding white light fills the island, before the island isn't there at all anymore. Wow. Who knew moving an island was that easy?
This is bad news for the copter crew, though. They crash into the water, but survive miraculously. They're floating around in the emergency raft with no land in sight, and things look grim. Wouldn't you know it, though, they're saved by Penny's boat. Desmond and Penny finally have their heartfelt reunion. Jack realizes that they have to do as Locke said and lie about the island, though. Is he finally becoming a man of faith? The six have to part ways with everyone else, and create their cover story, leading them to rescue.
Oh, I didn't even really mention the flash forwards, either. Sayid gives Hurley a late night visit, and the two depart together. Hurley really seems to have gone off the deep end, playing chess with "Mr. Eko." Kate also gets a late night visitor in the form of Claire, warning her not to bring Aaron back to the island. Finally, Jack breaks in to funeral home where he is visited by Ben, who claims to have a few ideas how to get them all back to the island. He says, though, that all of them have to come back together including the man in the coffin who is Locke. WHAT??!?!?! Why would Locke have left the island? How did Locke leave the island? How did he he die? If the Oceanic 6 have spent three years away, what are they going to find there when they return? Certainly three years will have changed the rest of the survivors in a big way. Or will it have been three years at all? There have been some weird time shifts going on there. Man, these Lost writers really know how to make a finale. Every single one so far has been just magnificent. Well, bring on Season 5, then.
