Yep; clearly the Cardinal appreciates competence.:) (The scene in the book between Richelieu and D'Artagnan when D'Artagnan presents the Cardinal with the carte blanche Richelieu had given Milady as a way to get out of punishment for the Musketeers having her executed and Richelieu can't help being impressed highlights that as well.)

Yes, let's hope that is indeed the turning point for female guest stars. I can't help but hope for more Christine, if not in the show, then in fanfiction.
