Polignac agrees to marry off 11-year-old Charlotte to Duke Guiche, a powerful but shady middle-aged man with an unhealthy fetish for young girls. Charlotte is so terrified of her suitor that she faints upon meeting him. She begs Polignac not to force into the marriage, but to no avail. Rosalie trains and improves drastically in order to avenge her mother, but Oscar wonders what Rosalie would do after this is accomplished. Andre finds out that "Martine Gabrielle" was the former first name of Polignac; in other words, Rosalie's birth mother was the murderer of her foster mother. Rosalie accidentally overhears Andre telling Oscar this, and claims that she feels no love for Polignac in spite of their relation. Oscar tells Rosalie that she had lied when she offered to help with her revenge, hoping instead that time would've caused her to abandon her revenge plans. Rosalie follows Polignac to a party hosted by Guiche and attacks her carriage, but is unable to bring herself to shoot her. At a ball later, Guiche forcefully kisses Charlotte's hand, causing her to go insane and commit suicide by jumping off of a tower. Rosalie claims that she does not mind that Charlotte died, but begins crying, realizing that she truly cared for her sister.
