It seems like they wasted time in other episodes, then had to rush this finale, but it was enjoyable. Looking forward to next season.
Chartres was under a 50 mile restraining order from Louis, so not sure why he was back in Versailles at the end. I think this romantic triangle or quadrangle with him and MA is invented by the writers, but Fersen and MA were definitely having an affair and there's a lot of letters written in code between them. I don't think Louie knew it yet, or had anything to do with him going to America.
I was glad to see Louie and MA go from perfunctory to passionate sex. lol
Ben Franklin was already 70 and grey about this time, he looks pretty good here.
