I think Andre was really tasteless and oblivious when he asked Barnabas to convince Josette that she did nothing wrong. Alert servants should have rushed in immediately, grabbed Andre, and taken him by force to his room and made him take a nap, which might have restored his sense, since his brain needed a rest. (No disrespect whatsoever meant toward anyone who disagrees, just my impression on this viewing.) Barnabas is consumed with rage, still, toward both, even though the love keeps mixing in with it. Barnabas feels betrayed to put it mildly. He and Josette both have their guts twisted inside out, with blame shooting off in all directions, and guilt. Andre might as well have had Josette tell Barnabas it wasn't his fault, even though Barnabas just shot Jerimiah in the face. Andre, there's no easy quick fix for your daughter's emotions, just let it be.
This episode might have my favorite Anthony George performance. Yes, I realize he wasn't there, and the extra might have just been a dummy with a sack of potatoes for a head. Except when walking.
