I just realized that if their was a demigod Cahill they'd be related to the same people in both sides.

Say it's one of Athena's kids, they'd be the half siblings of George Washington on their Mother's side, and somehow related to George Washington on their fathers side.

Quick question: Athena could be bi and still have kids? She has brain children, so could/would she fall for a girl?
Lots if fanfic opportunities in this update.
