it was like something inside Percy snapped, he became this whole other alter ego of his that wanted to get rid of his friends and family, of course no one knew this until the very fateful day Percy’s friends and family decided to capture the slasher, and that’s when they found out, it was someone so close to them, that they least expected, their very own hero, Percy Jackson.
