I hoped for her to slow him down some. The forces we have here aren't a military threat; they're a large shell of ablative meatshields, intended mostly to keep Braedonnal from getting shot until he can reach Rhuobhe. The fundamental question regarding the clash between Hermedhie and Rhuobhe was never "can she stop him", it was "how quickly will our meat be ablated?" The answer, sadly, looks like it's going to be "remarkably quickly."
