The youngest of Cleopatra's siblings and half-siblings, he is a happy young boy. Cleopatra notes that he's eager to please, though she admits that some of that may be caused by having seen the penalties imposed on those who oppose the rulers of the family. He lives as Cleopatra's co-ruler and is husband in name only, seeming to rely on her more as a parent figure than either a sister or a wife. He goes with her to Rome but complains of being homesick and is ill much of the time. He dies of consumption soon after their return to Egypt.
