Guinevere could not help but feel tense after what happened with her darling Sybille. Perhaps it was having Mr. Nott here while it happened. Perhaps it was simply her lack of enthusiasm of her daughter's hobby to begin with. Either way, she had yelled at her daughter and hated that. Now things were more tense and she couldn't stand it. So the very mention of good news made her positively light up. "Oh, how wonderful! I'm so happy for the both of you."
