They'd have blamed Diana
I know this will come off as cynical to some people, because that's actually how I feel -- but I believe the Queen and Prince Philip, and perhaps others in the Royal Family and the press would somehow, some way, have blamed Diana. I know there are those who who blame Charles for the accident of Diana, saying he and the Queen, Philip, etc. plotted her murder. I am one who believes it was a tragic accident with Diana. So I don't mean I think people would have thought Diana planned Charle's murder. But I think they would have thought Diana caused emotional turmoil, and I don't know what, because it's too far-fetched to understand. But they blamed Diana for everything when she was alive, tried to get people to think she was unbalanced. So they'd have blamed her somehow. And I don't think she'd have gotten her title back. I don't think she'd have had full custody or say-so in raising the boys. I think nothing would have changed. Oddly enough, I think Charles towards the end actually had some feelings (not love, but kindness) for Diana and once he was gone I don't think the rest of the Family would have cared about her at all. The boys would have been much better off because I think she was the best part of their lives and kept them human, and no children should have to lose their mother when they're so young, so for the sake of the boys I think things would have been better. And certainly Diana was the shining light in the Royal Family, so there would have been continued appreciation for all things Royal. But sadly, otherwise, I don't think it would have helped things or changed things at all. Except Camilla would have been without the love of her life!! What an intriguing thread, though!
