Athene considers how to exact revenge against Hephaestus and Poseidon.

The Medusa-Narrator describes Poseidon’s capitulation to the Nereids, including his wife Amphitrite. He complained to Zeus about the Gorgons and currently sulks at the loss of his land to Euryale, who pushed away the shore of Ethiopia (Part 1, Chapter 10), and the Nereids suggest he flood Ethiopia on their behalf to punish Cassiope’s hubris. He considers the ramifications of goading Hephaestus to pursue Athene and his own sexual assault of Medusa. Returning to Amphitrite, Poseidon voices his hurt pride, and like the other Nereids, Amphitrite encourages him to punish Cassiope.

Andromeda suspects that tragedy will strike. Suddenly, Cassiope and Cepheus hear movement and screams.
