The Woman with the Velvet Necklace/YMMV

• Nightmare Fuel: Arsene is dead, and only a slim ribbon keeps her head from falling off.
• Purity Sue: Antonia, so much, and her mother.
• Uncanny Valley: Arsene. At the start, she's an incredibly beautiful and graceful dancer. But when Hoffman finds her alone -- after he's gotten word that she was executed -- she moves in a strange way, like a puppet, and speaks in a flat, emotionless voice. She also doesn't react when a burning hot coal touches her foot, won't eat, and when she drinks a little champagne, the champagne trickles out from underneath her velvet necklace. It turns out, she was Dead All Along and somehow reanimated -- or may have been an insane hallucination from the start.
• What an Idiot!: Werner and Hoffman have been making plans to meet up and stay together in Paris for months, now Hoffman has finally entered Paris during the revolution -- but he somehow forgot to tell Werner the exact date of his arrival, the fact that he was arriving at all, and somehow Werner failed, during these months of communications, to tell Hoffman where exactly he lives. Hoffman is stranded then in Paris without anywhere to go.
