There is evidence that MM plays the long game. She has done exceptionally well in life given her start point and ‘talents’. She has stood on the neck of many family member, close friend, colleague, ex-husband to move herself up in career and society - very Undine Spragg.
She was never staying in the RF - her eyes were always firmly on the prize which for her was Hollywood A list Elite - not some stuffy, crusty, relatively ‘skint’ European royals - she arrived with her lawyers, agents, PR team and financial advisors in tow. They did a great job whipping up deals for her in LA where off she popped with her stepping stone useful idiot.
But climbing so high exposed her to the world but more importantly to her A List Hollywood Elite as a talentless, grasping, reactive, loose-lipped bully - the worst type of grifting duplicitous character they need in their trusted closed rank network. So she has squandered her opportunity by climbing too high - although I suspect that as is usual with these characters they get found out on most rungs of the ladder and move on quickly.
I suspect they are here TOGETHER to create content for commercial opportunities, to attempt to reconnect with RF so her DC and DH acquire royal glitter - but this is solely to boost her post divorce status like Diana and SF - plenty of grifting scope for the rest of her life there.
PH doesn’t know it yet but she’s leaving him here - it suits her personally and financially.
She ain’t staying this time either - it’s just a short term grift. It wouldn’t surprise me if she left the DC here as well saw them school holidays etc - they are more valuable to her as English sounding RF adjacent Prince and Princess than So Cal fake Fresh Prince of Bel-Air.
She always has a plan.
