User blog:It's Good to be the Queen/Mithian - woman scorned?

On this site it's been mentioned Mithian meets Morgana and it's possible they will team up, hence her darker appearance. My question is WHY? Mithian has to know Morgana is Camelot's greatest enemy (Mithian almost married Arthur afterall.) There were tensions between Camelot and Nemeth over disputed land (the reason for the political almost marriage). Why risk Camelot declaring war on Nemeth for providing comfort to an enemy of the state? If the writers go for the hell-hath-no-fury angle - Princess Mithian is p.o.'d that she was dumped for Gwen, the blacksmith's daughter - it would be a disappointment. Mithian looked like she took the break up with grace, although she presumed her rival for Arthur had to be a noblewoman. Arthur gave her the disputed lands as recompense. It would also show Mithian is not too bright in this area, Morgana would see any woman Arthur marries, be she noble or commoner, as a threat because Arthur's wife would be come queen. Who's to say Morgana would not have ordered magical hits on Mithian if the political match did go through? I hope the writers will flesh this thread out intelligently, the season is off to a great start.
