It would probably cause a big uproar with the public, but I doubt it cause a big uproar within the family. Everyone in the royal family are honest, wholesome, upright, and good as well, so I doubt they would have a problem forgiving her. I doubt she would be so horrified over something so trivial. I don't think she would keep that from Graham. Do you think Graham would leave her or something? I think it would have to be a matter of life and death for her to keep it from her own husband.
