While she was pondering her revenge, she came across the viscountess, one day, as she followed a path in the countryside. Suddenly, Emma get closer to her rival and hit her face. Unhorsed, the viscountess fell on the ground. Emma send her guards on her, who hit her and raped her, letting her bruised. Almost dead.
