I cannot imagine Loial refusing to do what Erith says because he is so traditional and obviously in love with her. However, I cannot believe that he will simply pack up his books and turn away from the Last Battle. In this way he reminds me very much of Tolkien’s Ents: he is very slow to anger, but a terrible enemy when roused. I believe that he has seen more than enough of how the world is threatened by the Dark One and realizes that hiding in thewill not help the Ogier to avoid destruction. I am quite sure that he thinks that the Ogier have a responsibility to do what they can to help in the Last Battle and he will do everything in his power to persuade them to join in the fight. I doubt that Erith and his mother will approve of this, but we might find that their time in the world of man has opened their eyes to how the world is changing so that they actually agree with him.
