"The toxic, racist people who made his wife mentally ill?"
Mmm, to quote our lovely, late Queen:
"some recollections may vary."
I highly doubt this was a secret meeting regarding any form of reconciliation with Harry. For one thing, if it involved secret talks, it wouldn't take place on a balcony where it could be photographed by the press, having been tipped off by H & M, no doubt. The RF are much smarter than that.
In addition, what would the RF gain from this reconciliation? H & M are very unpopular in the UK, one of the reasons being they're regarded as untrustworthy and anti RF.
They happily burnt their bridges, it's too late now for a "reconciliation."
