The defeated Cato and Scipio fall back on the African city of Utica after the Battle of Thapsus where they decide to end it all. Caesar, after two years of fighting in Greece and Egypt, returns to Rome and receives a hero's welcome. Meanwhile, Servilia's cold rage against the Julii clan makes Brutus's submission to Caesar even more painful. Octavian returns home from military school and Caesar, impressed with his nephew's incisive political acumen, appoints him a pontiff despite his youth. Having opened and operated a profitable butcher shop, Niobe and Lyde get the reluctant Vorenus and Pullo to join the trade, but Vorenus again crosses paths with the thug Erastes, now the crime lord of the Aventine. Learning of Caesar's secret "affliction," Servilia persuades her lover Octavia to cajole her brother into revealing more, but she only learns Niobe's secret instead. Servilia motivates Octavia to try again by other means, with dreadful consequences for both sister and brother. Pullo's affection for his slave Eirene deepens. Enraged at Servilia's manipulation of her children, Atia enlists Timon and his band of thugs to retaliate, thus escalating the term 'catfight' to a very different level.
