You and Percy first met at 12 years old back then you were the one protecting him from Clarisse telling her to shove her spear up her a$$ or whatever

Now years later here you two were again in the same situation except a few differences, you were behind Percy who had a protective arm in front of you guarding you from some douche bag Ares boy

Long story short the guy was harassing you and when Percy saw he punched the guy in the face Percy was no longer the forbidden new kid he was a hero
