Patron-Minette is definitely at the top of his thoughts! I dunno about Thenardier - I haven't read most of the other relevant bits yet (I'm currently skipped back to the rescue of Cosette and the first account of the Gorbeau house. And the Bishop, with the Tumblr read-along.) I believe he is looking for Thenardier in the sewers, but by that point Thenardier is also a prison escapee...
