In the final of the tournament, Agrippa faces Decius, whom he defeats and is about to kill him when Maecenas arrives in the arena, announcing the return of Caesar. He explains the man killed was a decoy employed because Caesar knew about the conspiracy, announcing the murder was carried out by Decius, not Vipsanius. Caesar arrives and addresses Antonius, telling him he did not chose him as his heir. Iris and Charmian revealed Caesar's true choice to Antonius, who masterminded the conspiracy. A shocked Antonius admits his guilt, at which point Maecenas reveals Caesar really is dead, and the man pretending to be him is his true chosen heir - Octavianus. A furious Antonius orders Decius to kill Octavianus, but Agrippa intervenes and kills Decius. At that moment, however, Rome is attacked by Sextus, supported by soldiers loyal to Antonius, who is able to escape the arena. Agrippa and Claudia head to Ostia and confront Sextus. Agrippa defeats him and begs him to surrender. However, Antonius attacks the docks, and Sextus sacrifices himself to save Claudia. As a battle rages at sea between those loyal to Octavianus and those loyal to Antonius, Agrippa faces Antonius, whom he defeats and kills.
