So could we can these tedious and unconvincing references to the Duke's female liaisons? They're unnecessary and out of character.
(No, I know we can't, not when Heyer was writing. But she's clearly going to draw out the Duke's obscure intentions in re his (safely aged up) page as long as she can get away with it. Note that no one really believes Leon is actually 19. He's obviously a precocious 15-year-old bishie.)
