Other students were in the same boat as I was, as far as power went. Even the seventh-years were frightened of Umbridge, as I found out when I tentatively felt them out at prefects'meetings. About the only people in the school who weren't afraid of her, as far as I could tell, were Fred and George Weasley, and I hesitated to bring them on side any more than they already were with the DA. While they are useful allies when they like you, they're very unpredictable and I do not think they will approve at all of my ultimate goals.
