Jason Grace Timeline & Summary

Jason banishes the ghost of his mother shortly before getting impaled by a sword.
He rests on the Argo II while his friends hunt for the ingredients of the physician's cure.
When the Argo II is swept up in a storm front, Jason assists Percy in getting to the cause.
They find a minor goddess who is trying to kill Percy Jackson. (Natch.)
Jason bargains with the goddess for Percy's life, agreeing to build shrines to the minor goddess so that people will fear her.
Somehow, helping Percy cures Jason's sword wound. Whodathunk?
Jason helps his friends battle the giants atop the acropolis.
When the gods come to assist, Jason finally gets to meet his dad, Zeus. "That'll do, pig. That'll do."
Gaea is raised anyway, and Jason tries to stop Leo from sacrificing himself to defeat Gaea.
Jason fails to stop Leo, but he believes that Leo is somehow still alive. (And even though Jason doesn't know it, he's right!)
