If you're as addicted to this show as I am, I'd love to hear your theory on the show's premise. I'm fairly certain we're dealing with time travel through multiple dimensions. Ben is desperately trying to keep the original timeline "contained", but with the murder of his daughter things are starting to unravel. Now Ben has recruited Sayid as a hit man to help put the original timeline back into balance. I still haven't figured out why the already dead characters keep popping in & out without staying longer. Perhaps the island is a main portal to the other dimensions. One thing is for sure...this has been one wild ride!
