Leo Valdez Timeline & Summary

Leo hopes to find a way back to Ogygia, the island where his love, Calypso, lives.
He gives his friends gadgets to defeat and trap Nike, the goddess of victory.
He bargains with Apollo to get the final ingredient for the physician's cure, which is supposed to bring someone back to life.
Then he accompanies them to Asclepius' office, so that the doctor can make them the physician's cure.
When Gaea is resurrected, Leo uses Festus, the dragon figurehead of his ship Argo II, to capture Gaea and haul her high into the sky.
Far enough from her power source, the earth, Gaea is destroyed when Leo blows her up.
But he blows himself up too.
Oops.
However, he manages to self-administer the cure and bring himself back to life. Phew.
He flies to Ogygia and is reunited with his true love, Calypso.
