Whoever that lady is, she's an idiot, if she still believes whatever BS the prince is feeding her. You'd imagine, that after all that time and all the crap the prince has obviously done, she'd have at least one functional brain cell in her head, telling her "Don't listen to this scumbag, he's nothing but a big fat liar and a greedy little dipshit. Heck, if you get the chance, slit his throat", but I guess that's too much to ask.
