The Argo II flies over Greece and stops close to the House of Hades. When Frank gets Coach Hedge for the battle, he overhears him talking to Mellie. Coach Hedge explains he married his girlfriend, and she’s expecting a baby at Camp Half-Blood. Coach Hedge wants to protect her but can’t. Frank promises not to tell anyone.

Leo asks Hazel for the piece of firewood that represents Frank’s life and puts it in a fireproof bag. Frank is unconvinced it will work, so Leo asks if he trusts him. Frank hands it over, and Leo tries to set it on fire but can’t. Frank feels a huge weight off his chest and decides to carry it into the House of Hades. They see darkness emanating from the House of Hades. Nico holds Diocletian’s scepter, which makes Frank nervous because Nico still doesn’t know how to use it. Frank suggests Coach Hedge stay behind and guard the ship, and Jason leads the rest.

Nico leads the crew to the House of Hades where they eat the barley cakes from Triptolemus to protect them from the poison, and then they go inside to the chalice of poison.
