Actually I hope they don't change it. I know the old rivalry of brother against brother is too good to resist, but I just hope they don't go there the show is pretty good in its debut. They don't need what I feel would be a cheap out or stunt, in changing Christopher paternity which is the way I see it. Although I would like to see more cast of the next generation later added to the show. But I think this good for now to establish the characters of John Ross and Christopher then add the others at least by season 2.
