Don't disrupt the ceremony? Don't disrupt the ceremony? Like that was what she'd planned to do? If she wanted to disrupt the ceremony, she would have been dragged toward him kicking and screaming because it was the last thing she wanted to do. She was trying to give these people, her people, a ceremony! Just who did he think he was?
Rosmerta really wanted to glare at him, but that would have “disrupted the ceremony.” So would kicking him, probably. And hitting him over the head with the garlands draped over her. Repeatedly. And that athame would come in very handing for stabbing him. Alright, that one might be a bit too much. Unless she stabbed him in the butt. It was a nice fleshy area, it wouldn't do a whole lot of damage, but it would make him jump. And stop telling her what to do like he was already in charge of her.
She amused herself with thoughts of ways to hurt him, or shut him up, or humiliate him, until she felt better. Well not better. Calmer. She was calmer. It wasn't as though she had to concentrate hard on what was being said. A cord was wrapped, a question asked, and all she had to do was answer in the affirmative. Then it was repeated. And repeated again. So her attention was mildly diverted.
But when the elder finished with his questions and raised his voice for the blessing, Rosmerta murmured low, “I wasn't given the option of the chalice. Believe me, I would have taken it.”
