Take Back My ThroneEpisode 4

Queen Matilda is brutally killed after Duke’s daughter Isabel slaughters her family. Resurrected and remade into a palace dancer Cecilia by vampire blood sorcery, she returns for revenge. Using King Arthur’s favor and vampiric charm, she dismantles her enemies: driving Carla mad, dethroning Isabel, causing Elsa and Brianna’s mutual destruction, exposing Vera’s affair, and ruining the Howard family. To advance her plan, she stabs her former loyal ally Roy with her own hands, breaking completely with Arthur and leaving the palace. She later discovers Roy survived, along with a shocking truth: Arthur has known her true identity all along. For three years, he sustained her life with his heart’s blood, and forcing her to kill Roy was merely a bitter deception.
