Wow, so much drama...
1. Charles-Henri standing up to his grandma, something none in this family do was powerful, but I'm sure they have their ways of forcing him into submission.
2. Jean-Baptiste, completely mind-broken, most likely due to sickness, strokes, whatever happened to him. Man regressed to a child so much, that even his mother didn't know what to do. I'm actually surprised she cared. Fully expected her to beat him into "normalcy".
3. Marie-Joseph won't have a soft spot for Charles after all, as I should've expected from a psycho. This saddens me a bit, actually. Normally there's at least this small ray of hope in every darkness, but I guess not for Charles-Henri or at least not yet...
