The Alt Is The “Real” World
I’ve been talking about this in some of my comments but I thought it would make a good theory. I believe that the Alt we are seeing is the Real World. Smokie is trying to the leave The Island to reenter the Real World which will lead to the destruction of everything we know and love. The Island is the cork protecting the Real World from this evil being. This is why Widmore says “I didn’t murder them” when Sawyer asks why he killed the Ajira passengers. Widmore knows they exist in the Real World and on the Island they are not in their “real” existences. This is how people can do seemingly evil things on the Island but not be marked as tipping towards the dark side (Ben for example). Some people’s consciousnesses can flow between both like Desmond (Hawking’s, Widmore, etc) and can understand the whole picture.
This is why Smokie knew some of them survived because he was still on the Island and not in the Alt aka the Real World.
what do you guys think?
