Ep. 19: Polignac forces Charlotte into marriage while Rosalie seeks revenge for her mother's death.

Polignac arranges for eleven-year-old Charlotte to marry Duke Guiche, a middle-aged man with a disturbing fetish. Charlotte faints from fear and pleads with her father, but he refuses to cancel the union. Meanwhile, Rosalie trains intensely to avenge her mother, prompting Oscar to question her future goals. Andre reveals that Polignac’s former name was Martine Gabrielle, proving Rosalie’s birth mother killed her foster mother. Rosalie overhears this and denies loving Polignac. Oscar admits he lied about helping her revenge, hoping time would make her give up. Rosalie attacks Guiche’s carriage but cannot shoot. Later, Guiche kisses Charlotte’s hand forcefully, driving her to jump from a tower. Rosalie claims indifference to Charlotte’s death but cries, realizing she truly cared for her sister.
