Sketching Les Mis Chapter 3.8.22 - The Little Boy Who Cried In Part Two
~ End Of Volume 3 ~
So Gavroche came home one night. Ran into the old landlady scavenging through a pile of garbage and made fun of her because that's what you do when you're Gavroche. Nothing is above your irreverence.
Then, when he kicked the door of number 50-52 she told him that all his family was in prison and no one lives there anymore. So he left, skipping away and singing a rhyme about a king hunting crows wearing stilts, and people walking under him having to pay 2 sous for crossing (remember that the Gorbeau house was named after a guy named Corbeau, AKA crow, who changed his name) (a crow by any other name would smell as sweet amirite? you can change your name all you like master crow)
Hugo is making a point here: volume 3, Marius, began with the Gamin digression and it's now ending on Gavroche. It's not just coincidence, it's foreshadowing! The Paris gamin, according to Hugs, is a key component of all the events of historical significance, not just as a participant but as a witness. And since Paris is a microcosm of the world, the figure of Gavroche returning again is an omen of underlying things that are coming to light.
