I’m so down with the idea of Cosette having a stash of Fantine’s letters. I imagine her stealing them out of the fireplace as a kid and storing them under her pillow. And then one of the first things she asks Valjean is if he can read. He says yes, and she pulls out a bundle from under her dress and asks, “What do these say?” They’re mostly short little notes, (because long letters are expensive to have written): “Here are your twelve francs.”; “The rest will come soon.”; “I’ll have it in a week’s time.” But they always end with “Give Cosette my love.” And she asks Valjean to show her which part that is, and he points and says “this word here is ‘Cosette’”; “this here is ‘amour’”. And so she learns those words from her mother.
