I love doing this with you all too! If I didn't have a fic list to tackle that is a mile long, I'd say we should do it very soon.
I'm beginning to think I won't even get to the Thenardier parents. Sorry Acaila! I know that was the original intent of the prompt, but the muse pulled me the direction of the Thenardier children instead.
Edit: Actually looking at it, I just realized that M. and Mme. Thenardier do make a small appearance in the story, so I didn't completely fail on that point.
