Duelling is outlawed
Jussac sure forgets fast that his troupe is supposed to counteract duelling. Very cool irony that when d'Artagnan and the guys challenge him, the fight turns into a quadruple duelling meeting.
I'll have to borrow that for my signature:
"Gentlemen, duelling is forbidden by the orders of Cardinal Richelieu!"
"Richelieu's men are notorious for their complete lack of taste."
