Royal experts are unlikely to be able to divine the ways of the Meghan. If she is not allowed to bring in her body cams and microphones, she will look for other ways to steal the limelight.
Diminishing returns are kicking in. I am no South Park fan, but that portrayal was brutal, spot on and reached a very large audience outside of royal watchers.
The Archie birthday tie-in is interesting. If she and Harry both attended, she wanted the post coronation dinner or reception to begin with everyone singing Happy Birthday to Archie and was told no-way.
My wife hates South Park, but she watched that episode and loved it.
