Michael tells Hurley that he’s stuck on the Island, and he implies that he’s not alone. Michael says that they’re stuck on the Island, they can’t move on. We heard a few different times in the Afterlife about moving on. I guess that means that Michael couldn’t get to the Afterlife. That’s unfortunate. But it’s an easy way to explain why he wasn’t there. Kinda tricky.
Ben says that Hurley will be able to help people as the new Jacob. I wonder if these Whispering dead people are some of the people he can help. That would be pretty awesome. Hurley actually asked Michael if there was anything he could do, Michael just says, “don’t get yourself killed”.
I kinda like this explanation.
