Synopsis by Josh Ralske
Caesar (Ciarán Hinds) goes to Egypt, and goes to the court of the boy king, Ptolemy XIII (Shaka Bunsie), to demand that he turn over Pompey. Instead, Pompey's head is produced, and Caesar is not grateful, but enraged. He in turn demands that Ptolemy turn over the man who killed Pompey. The Egyptians have their own political strife, with Ptolemy's sister, Cleopatra (Lyndsey Marshal), having claimed the throne. Caesar decides to stay in Egypt and mediate the dispute in order to insure Egypt's grain supply to Rome isn't affected. But he sends Mark Antony (James Purefoy) and most of his men back to Rome. Vorenus (Kevin McKidd) and Pullo (Ray Stevenson) are sent to find Cleopatra, before Ptolemy's advisors have her killed. They rescue her, and she immediately plans to seduce Caesar, but on the road back to Alexandria, Cleopatra decides that since she is "between the tides" she must conceive a child immediately, before she reaches Caesar, and pass the child off as Caesar's own. She makes a surprising choice for the father. Upon returning to Alexandria, Cleopatra and Caesar have Ptolemy's advisors executed, which causes a massive public uproar, and Caesar ends up under siege in Alexandria for many months. Back in Rome, Brutus (Tobias Menzies) receives a cold welcome from Servilia (Lindsay Duncan) due to his capitulation. Antony keeps a sharp eye on Brutus and Cicero (David Bamber) while Caesar is away.
