I find the whole thing really butt clenchingly embarrassing, it’s moving from Royalty to talentless tv reality stars.
At the moment they’re kind of lab rats for the media/Hollywood prodding them to get the dirt on something they previously didn’t have access to. Eventually, once they’ve dished the dirt, their cache will rapidly diminish, then what?
Anyone who marries into the royals is ambitious, so much sacrifice of self is needed to join The Firm (I believe this is what. The RF have referred to them self as internally for a long time -not something MM has made up), the person marrying in will undoubtedly make these sacrifices in expectation of something.
I think Kate, with her long courtship knew this and fitted in quite well.
MM seemed to have some sort of fairytale reward for her ambition in her head. She didn’t realise what she actually would have to give up. But the woman clearly expects her marriage to reap rewards. No one young is going to marry into the RF for love only.
Once those rewards disappear, and they will, will she stick around?
