She allows Turner/Mrs. Winterton to shade her to her face, then delivers on her promises and goals. It takes great restraint, I'm sure, but the final result always outshines any doubts Mrs. Winterton throws at her.
I don't dislike her, but I'm not a fan, however, I think she's well acted by Carrie C, and I do like that she and George seem to have an enduring marriage.
