I think Andrew is so convinced that he is a gentleman and deserving of the royal finery and that Fergie has an actually great relationship with the queen that B&E took all that as gospel. I think in a weird way they have created a loving family. B&E are definitely lucky and I hope they never or only superficially came into contact with the unsavory types who are friends.
Well, one wonders. Epstein attended Beatrice's 18th birthday bash, and this Keogh attended Eugenie's wedding. And Ghislaine was an even older friend of Andrew's.
If these were tit-for-tat friendships, no pun intended, and it seems like Andrew doesn't have others, then being visibly and often in Andrew's company (or at least being able to say they were "friends" of his, ugh) was the payback for getting Fergie out of her many credit failures or helping Andrew with ... whatever he wanted.
Let's just hope the occasional
function with their daughters in a large crowd of people, was as close as they got to the daughters.
