So it seems that people in the alt verse are starting to get their memories back of their lives on the Island. Libby and Hugo go on a date, kiss and remember as did Desmond and Charlie. It's like the only interesting thing happening on Lost so far.
On the other side, Jacob's followers have decided to blow up the plane but that doesn't quite work out. First Ilana blows herself up, and they head to the Black rock for more Hugo turns the ship into charred rock because the ghost of Michael (turns out him and the ghosts of many of the others are stuck in limbo on the island for some reason) told him not to. Hugo instead leads Jack, Sun, and the pilot to Smokey's camp of all places. Normally Jack puts a hell of an argument anytime he's told to do something but as crazy it sounds he opted to put his faith in Hugo instead.
Sayeed brings Desmond to see Smokey who after taking him on a moonlight stroll through the woods throws Desmond in an electromagnetic well. Puff….just like that, and that is all that happened of consequence on the Island. For a cliff hanger, alt Desmond runs over wheelchair bound Locke with his car. I have one word for that, retarded!
For a show that has built itself on mysteries suspense, and now that it's coming to end, you would think they would start answering all those questions you know? One obvious answer divulged (if you haven't figured it out yet) is that leaving the island will only be possible if it's done by everybody, together. They came together, they leave together.
