I don’t think Charles is desperate to see Harry. He hasn’t seen him since they met for less than an hour last September. Before that was 18 months earlier, the fleeting visit when Charles’s cancer was announced. Before that was the coronation. So they have seen each other twice in 3 years, a total of 90 mins or so together since 2023, despite Harry being in the UK multiple times and Charles’s state visit a couple of months ago.
The Sussexes would love us to think that Charles is pining away, desperate to see his grandchildren, and it’s Harry that says no, because the UK is too dangerous and he has to keep his family safe. Absolute bollocks of course. Charles is not an idiot. He must also be deeply hurt by Harry’s behaviour. So must Camilla be. And with everything that’s coming out about Andrew, he sees what damage can be done to the RF reputation by entitled oafs. Harry is very unpopular here and even if that changes, he can’t be trusted. He lies, he gossips, he complains, he lies again, he embarrasses himself trying to make political speeches when he has no clue, he slaps an arse here, tweaks a nipple there, he lies again, he complains again, he speculates about how long his father has left, plays some Xbox, lies again, accuses Charles of collusion in an establishment stitch up, dances around pointing at his crotch, lies again.
This is not behaviour that Charles would consider appropriate for a member of the RF. Charles knows he has to be very careful managing how close Harry gets to the family and the institution, treading that line between just cutting them off, which might look callous, and letting them milk their RF connections. Tricky, but so far the RF are managing it pretty well I think.
