I don't think it's anything as sweet-natured as this.
KC met them, I bet, for strategic reasons. There were strict conditions - I'm sure H wanted to see his father alone - to beg for money etc - but Camilla was there, which H will not have appreciated. Wonder how that went, considering what he's said and written about her?? And I bet there were officials there, and that the Dodgy Duo were frisked for wires etc before the audience.
Apparently Meghan was allowed in at the end with the kids.
I don't see any rapprochement - how could there be? Charles has to keep William on side and there's no chance of any reconcilation there. If KC brought H back into the fold and I was William, I'd walk and go and live a private life - a real private life, not the Z-list celeb life H & M seem to crave.
I think KC did brilliantly - just enough to shut H & M up and not quite enough to alienate William, who must be his priority now.
