1. Interesting that there is a coffin with a dead guy on this plane too. Maybe John will come back and be Zombie-John with Zombie-Christian.

2. Ben telling John that who ever turns the wheel can never come back might only have been a way to keep John from turning it himself.

LiKe yOu SaiD, “Glass houses, my friend. Glass houses.”

You mean like putting periods and commas outside end quotes?

Glass houses, my friend. Glass houses.

So if Jack, et.al. recrash it could be very similar to 815. Some people on board knew there would be a crash. Something on the Island causes the crash. Maybe “they” are able to find the Island because they know the history of the Island. In 2008, they knew a plane crashed on September 22, 2004. It’s all a matter of determining what the true present is. Maybe EVERYTHING is a flashback.

BEN: He told you what to do, but he didn’t tell you how because he wants me to suffer the consequences.
LOCKE: What consequences?
BEN: Whoever moves the island can never come back. So I’d like you to get on the elevator, John, and go back up. Richard and my people will be waiting 2 miles east of the Orchid.

Or, they were “christened” in the temple, so they became “part of the island”… dunno, whatever Alpert and the rest had to do, to become part of the island.

Also, she said that the people Ben gathered would do “for now.” I believe that everyone will have to go back eventually, and Ben wasn’t on the plane because he still has to get Sayid, and maybe Desmond has to stay behind to help get Sayid and himself back, with Ben.

It’s clear that Desmond doesn’t want to go back to the island, but that doesn’t mean that he won’t go willingly, if not reluctantly. He told Penny that he would find Daniel’s mother and that would be the end of it, but she reacted as if she knew that it wouldn’t be over that easily, and that she would go with him regardless.

I think that Ben, Sayid, Desmond, and maybe little Charlie will end up back at the island soon enough. Sayid, most likely, will be going against his will – unless Ben comes up with a darned good argument. This also puts Penny within easy reach of Ben’s revenge on Widmore, though I don’t believe he’ll be successful – or maybe he’ll back down. Granted, couples in love have it rough on Lost, but Desmond and Penny’s relationship has been the cause of several key events. I think they’ll make it.

some things… Yes, Mrs Hawking says “this is how they found it”, but it could also be, that she WAS part of Dharma, yet she was also only “workman”, but destined to be much more. So, out of anger, she denounces her participation.

Then, ben says “he who turns the wheel cannot go back”… He doesn’t explicitly say “never”… So by any means, he can try to go back, but it does take major work, which in turn means probably asking help from a probable enemy (maybe Hawking).

Third we have the plane crash… What bothers me is the people, that were on the first plane and were taken by the Others (Cindy and others) in the first and second season. Were those people also ones who wanted to go back to the island? Was Lapidus their designated and knowing pilot? Because now this would make sense, as it happens again!
