Waterloo turns out to have been critical for the Thénardiers’ inn: Looting corpses got them seed money to start it, and “rescuing” Pontmercy got them a story for their sign.
The woodcut of Little Cosette drastically understates how badly she’s treated by the Thénardiers. So do all the movie versions I’ve seen, and the musical.
Cosette overhears Thénardier saying he thinks her mother is dead, and starts singing “My mother’s dead” over and over to the toy sword she’s swaddled and rocking as a makeshift doll. 😢
That said, it still amuses me that she sleeps in a cupboard under the stairs. Thénardier probably cooked the owls from Beauxbatons.
Describing the dismal neighborhood of the Gorbeau tenement where Valjean and Cosette live when they first reach Paris, Hugo remarks that monotonous architecture oppresses the mind. There’s actual science backing him up now.
Javert is very cautious during the chase through the Paris streets, because for most of it, he still isn’t 100% sure the man he’s following is Jean Valjean. Until he gets a good look at his face, Javert takes pains to just follow, and avoid making a false arrest (and getting fired).
Once he’s sure it’s him, and he’s blocked all the exits and is certain Valjean can’t escape, Javert starts having fun with the hunt. Ironically, this is what gives his quarry time to climb the wall with Cosette.
“…thinking he could play cat-and-mouse with a lion.”
