Hmmm... I think Jean-Baptiste was silently impressed by his son there, maybe first time ever. While, yes, he disregarded both the host's and his father's orders, he's done so in that silver-tongued, rhetoric 100 way. A way to which nobody could openly responded with malice, unless they wanted to be seen as the king's enemy, a traitor even.
I wonder what's in store though. I really need to read a bit about societal norms in pre-revolution France, because I don't even know how open one could be with liking the same sex as them. As for the Sansons, I doubt anybody would care. They have 3 daughters to prolong the bloodline and, unless I counted wrong, 2 other sons. If somebody does care, it'd be probably the grandmother and that still out of spite, as a way to control her family more.
That being said, I can feel something very sad brewing. We never heard who the conspirators (the ones after the party) want to hang after all.
