Now, I really really love the imagery of this one, almost as much as "The Last Supper" promo for Battlestar Galactica I used in my LJ header. Before anyone jumps in to analyze what this meant for where season 6 is heading, I want to point out that whoever made the artwork most likely had no idea either. Remember how much we analyzed "The Last Supper" to death back in the day? Turned out it was just a cool image to entice the fandom. So I think this most likely is the same too.
