Brilliant episode. Bits I remembered:
"Coitus interruptus." "I heard that." 
Dog's confusion with the three daughters. Lovely.
His amusement when they were trying to catch Serena.
Aramis's backstory. His mother's choices were always for the sake of her children. 
"Come inside, let's drink some wine." Love the slow burn between these two.
Glad they let Bonnaire and Caroline go free.
I thought of Baldrick too, when Feron said he had an audacious plan.
Hope WW manages to watch.
