Hillary was there too. Hill is bisexual and prefers young ones.
The British Royal Family is not having a good year. First Andrew, which is going to be quite a huge scandal.
Then Megan and Harry leave, which is fine, but they took Archie with them. Queen Elizabeth literally has custody of him and would love him far more than narcissistic Me-Again does.
I would suspect both Bill and Hill were most pleased with the entertainment on Einstein's Island. I think it would be a valid assumption they did not entertain each other.
I am confused by your post.
Did Megan and Harry take the baby with them and the baby is now in the U.S.?
Or...Did the royal family take Archie and the baby is now in the U.K. under the care of the queen?
