Bullcrap! It is absolutely his fault! He allowed her previous title of baron to fester in the nobility and did nothing to help her. If anything he prevented her taking her responicbilities as his consort. She was given nothing and she gave birth to the heir. THAT IS HIS FAULT!!! She was absolutely powerless and he completely ignored that. He did nothing and ignored everything, that is absolutely on him. Maybe this particular incident couldn't have been prevented, but we won't know that because he did nothing up till the point she insisted on changing the status quo.
