very impressive/obsessive... however there is one hole in it. The part about Alvar and his wife laying down to die in the caves. That is not Alvar. We know thru the Experience that Alvar is alive and well in the outside world. And I don't think he's even married. He had at least one child, Rachel Blake, but she was out of wedlock.

Wow, that's a great read even if it is a theory.

They've said before that the explanation is fairly simple, I seriously doubt there would be this much of an explanation. How would they ever get this across on the show?

I'm not that interested in working it all out in advance; I'd rather go through all the ups and downs they probably have planned - with TV series the journey tends to be better than the destination
