Well as for the Hanso descendants, somehow the Blacck Rock's Ship's Log must have made it off the Island and into Hanso family hands because we saw that it was up for auction (after the last Hanso died) and Widmore bought it.
Maybe they sent a ship looking for the Black Rock after it went missing? Maybe they found the Island and made it off with the log? That's kind of weak, but it's the only way that fits.
Unless someone abandoned ship during the storm, just before it shipwrecked and they took the log with them?
Maybe someone besides Ricardus survived the shipwreck/Smokey attack, stole the log, hid out, and somehow got off the island (via teleportation for instance).
I also want a good explanation for why the button-pushing was "saving the world." Also, what exactly happened when the island vanished? Did it move someplace else? Is it someplace else now? Was it in the Atlantic when the Black Rock wrecked on it?
That was a good theory until the episode where we saw the tail section slam into the water at a high rate of speed that should have killed everyone. Yet they popped up in the water right afterwards...like they weren't in the tail when it hit? Teleported into the water perhaps?I heard one person's theory a year back is that the same magnetic anomaly that caused the crash also slowed the plane's descent so after it broke apart, the magnetic fields caused the plane to fall at a much slower rate. Just a theory though, I'd like to see them address this as well.
Supposedly Kate remembers the entire crash. What did she see/experience?
That's just too easy. They needed to push the button to "save the world," yet there was a perfectly good workaround, which they stumbled across. Doesn't fit with the enormous build up of the importance of the button pushing. It makes the characters look foolish for pushing the button and the audience foolish for caring if they did.After Dharma hit the pocket of energy they saw that it needed to be released every 108 minutes lest it all build up. So the button in the hatch did that. When Desmond hit the fail safe it released the energy into the Island and activated the frozen wheel thus moving the Island. The effect of the Island moving is the same in both "Live Together; Die Alone" and "There's No Place Like Home, Part Two."
