After she recovers, the group relocates to Augustus’s luxury villa in Lake Como because Medusa has escaped from the Underworld.
At the villa, Alexis finds a captive muse named Ceres being tortured in the dungeons. Believing Ceres has memory loss, Alexis and Helen free her and hide her from the men.

Fluffy Jr. molts into a part dog, part Pegasus hybrid with massive blue wings, and Alexis rides him to destroy the Rome Titans.
Zeus forces Alexis to fight Augustus and Kharon in the final round. They refuse to hurt her, and Augustus mentally commands her to impale him so she can win without being branded.
Both husbands are branded by Zeus. Alexis later records Zeus confessing that he planned the Titan attacks and tried to assassinate her as a baby. She broadcasts the recording to the coliseum. Zeus flees, and the corrupt federation collapses.
