I don't know. I think that the RF are back to moderately popular and don't want any more dazzlers who end up in a disaster. Diana's charm and pulling power was a plus, at first. But then she began to use it against her husband and the RF.. and it all ended in scandal and tragedy. I think that it is problaby better not to have someone with so much of that special quality.. as it can end in disaster. Will and Harry have a reasonable popularity, but they do their jobs and then retreat to their home life.. and if they are not mega popular, they are less likely to crash and burn...
Why do you keep foresting that her "family" didn't treat her well too? Charles and the monarchy.
