I very much am a reap what you sow person.
I think the antics of H & M have been deeply sad, appalling and unnecessary.
But from a personal perspective, I would have thought that Harry might well feel very disturbed and distanced from his family The King with cancer and his SIL. It may well be throwing up a fair amount of emotion that he had not anticipated.
But finding out alongside the rest of the World about Catherine really does demonstrate how far removed he is from his family, as would have his last visit to see his father.
The fact he had stated previously he wanted an apology from the family illuminated how delusional he was about his actions and situation. The events of the last two months cannot have been any clearer to him the distance there is now, and not just in air miles.
However, I would think that both his father and brother are sad this is the state of play and perhaps both dwell on how if things were different they both might have an easier life with him in the family fold and a harmonious relationship.
