Vivian tells Morgan that people have been waiting since sunrise to ask for favors. The first group to ask her judgement is Warin, Mary's Son, and Mary. Mary tells Morgan that she and Warin haven't been together for seven years and now he wants Mary's Son to help him with his farm. Warin thinks he should have Mary's Son, because he is old enough to work and is the only family he has. Morgan offers to buy Mary's Son and after Warin tries to haggle with her, Morgan gives Mary's Son to Mary.
Arwen arrives at Morgan's castle and demands to see Morgan immediately. Sybil is telling Morgan what a good job she did and she should use her powers. Vivian walks in and tells Morgan that Arwen said she was in danger. Morgan walks into the main hall with Vivian and Sybil and Arwen accuses Sybil of being a devil. Arwen uncovers her face and reveals her burn scars. She says that her daughter was in the nunnery when Sybil set it on fire. Arwen tells Morgan that she wants justice and Sybil must be executed.
Morgan angrily yells at Vivian about the revelation about Sybil. During the hearing, Sybil asks for forgiveness and says every year there was a ritual and in order to hide it from the priests, she set the nunnery on fire. Sybil tells Morgan not to let Arwen's accusations take them off course. Morgan gives her verdict and places Sybil's hand in the fire. Arwen wants more, but is told to leave.
