It will be very interesting to see what happens next with this saga.
Will they try and brush it off and carry on, nothing to see here? If so I'd expect there to be some reports and maybe even some pictures from Harry's 40th celebrations. Be very interesting to see which friends he's rustled up to attend that - I'd be very surprised if it's any of his true friends from the past. I'd imagine Nacho and some of the other Hollywood acquaintances are most likely.
The atmosphere at home must be absolutely terrible though. She must be livid, he probably will too. The staff must be getting some kind of interrogation to try and find out who's spoken to the press.
I wouldn't be surprised to see some kind of performative puff piece in the next few days with Meghan sending a muffin basket to staff or something just to show how kind and considerate she is, and some member of current staff forced to go on record to talk about what an amazing and inspirational boss she is.
I do think Harry is just as culpable. He may not be as directly nasty as a bully, but in his own words in Spare we've seen that he's been resentful, mean spirited and bitter since a very young age. Lots of well publicised nastiness and racism too, from calling a pub landlord a "f*ing frog" to the racist slurs he used against his compatriots in the army. I think he was always a nasty piece of work but for the most part prior to meeting Meghan it was well covered up and he was given good role models for how to behave by his brother, father, aunts and uncles (barring one!) and grandmother.
I do think however that MM has brought out the worst in him. She's clearly a stone cold social climber who uses people and discards them when they're no longer helpful to her. She's absolutely tapped into Harry's worst insecurities and that's why she encourages the Diana 2.0 narrative - it controls him.
She might be the more overt bully, but he is equally as responsible by enabling and defending her behaviour. His attitude towards the little people comes across in Spare - he simply doesn't care.
They're both utterly awful.
