Yes, there is a chance he could join Jacob as leaders of the island, which would be interesting, aslong as we see just as much of him as we usually do, I hate that episodes are sometimes split into groups..like, one episode will be about the people on the beach, the next will be about Locke and The Others..it's annoying.
Also, with the spiritual thing, there's Miles. If all of these dead people who appear to be alive are just spiritual manifestations, I wonder what Miles would see them to be, seeing as he has that connection to dead people.
Thanks all, for welcoming me.
