I think they signed Sherry and Nina on to a 3 season contract and are pulling stories out of their ass' to find a way to sneak them into the plot. They should show more of the Presidents role in the crisis going on and not so much of his brothers problem. I know I wouldn't want my president (or PM in my case) trying to save his brothers career when a national emergency is going on. Also don't like the baby "story line" but other than that I am fine with the show. Don't really see it as too predictable.
