I Want to See the Black Knight! Episode 26

A masked vigilante called the Black Knight begins stealing from the rich and giving to the poor. His popularity increases to the point where marches are being held for him in the streets. Andre begins spending an abnormal amount of time outside during the evenings, causing Oscar to suspect him of being the Knight. She starts attending every ball available, because that is where the Knight usually strikes. He does so one ball after Andre mysteriously disappears. Oscar chases him into Palais Royale, Orleans' manor, rumored to be an anti-monarchist meeting place. Oscar is injured by the guards, but the Knight stops them from killing her. She escapes, collapses on the street, and has a nightmare where Andre is the Black Knight and is killed during a mission. Oscar is rescued by a peasant family housing Rosalie. She tells her that she left the Polignacs when they tried to force her to marry Guiche in order to expand their prestige.
