Pictures with the Sussex grandchildren will be interesting logistically.
I doubt H&M would allow A&L to travel to the UK (would be a bit of a climb down post his failed security litigation - even tho he took them both here and they were very high profile for QE2 Jubillee).
So would this involve KC3 (and QC?) travelling to US or neutral ground - Africa / Commonwealth? I can imagine safari type holiday snaps of the Sussex’s on holiday going down well for both parties. Would their faces be obscured?
Next step might be that they decide that a Sandringham Christmas Morning Church Walk would make them $$$$$? This might be tricky if PW is still frosty and might not be fair on all the children as people will be interested in interactions between the cousins / aunts / uncles.
Or maybe Balmoral in the summer - could legitimately separate out PW for that photo OP.
On a personal level it must be heartbreaking for KC3 barely to have met his DGC and especially at his age and health status. He also needs to be seen to be the wise compassionate player in this messy family situation.
