Thought you might be interested in an interview with Michael Emmerson by Andrew Dansby with the Houston Chronicle.Paragraphs of interest to me:
Emerson doesn't help Ben's cause when he informs, frankly, that in the land of Lost, "the day will come when we find out who he's really fighting. And it will make your hair stand on end. You'll wish Ben had been badder.
"Something's coming. And whatever it is will make the battle between the Lostaways and the Others pale."
He also mentions some business about "bloodshed on the horizon," but it's hard to be concerned about anything as specific as bloodshed with that "something" having been said in a voice that sounds just enough like Ben's to cause worry.
