The levels of depravity and disgust we're supposed to feel reading this, seeing those scenes, seems to be a direct reflection of what Charles-Henri sees, I think. How dirty and vile it all is, despite all the beautiful clothes, all the wigs and powder, feasts and grandness. I feel for Jean a lot too - it seems (until I'm proven otherwise), that his father isn't maybe too fond of his son being sensitive and men-oriented. Maybe that's why he's using him and humiliating him, while gaining better standing among his own peers?
And Jean-Baptiste - was he poisoned? Is it an elaborate ploy by someone who wants to discredit Sansons? Like, somebody who knows that Charles-Henri is weak, so they incapacicate Jean-Baptiste, so that nobody can actually kill the lion? That way, it could drive a wedge between Sansons and earl de Chartois, right?
