You were one of the popular demigods on Camp Half-Blood, a (you choose) demigod to be exact, and one of the best sword fighters along with Luke Castellan, other words, you were awesome
Percy, quite the opposite, was a new camper, no one knew about him, just that he slayed a minotaur on his way to the camp with his satyr protector, Grover Underwood, but everyone though he was laying since he acted so lame lol, and even he didn't knew how he did it tbh, he was just so angry that his mom was killed in front of his eyes, he was still grieving it
He was with sitting on the floor, doing literally nothing than just petting some geckos because everyone is playing Capture the flag, and Annabeth just told him to stay there
Chiron ask you personally to help Percy with his skills, because he clearly sighted and even got bullied the first day he arrived, which was yesterday, so when you come out from nowhere with your sword and cool armor, he flinched and stepped back, raising his sword, shaking and even holding the sword wrong since he was scared shittles "UHH- the spar thingy is that way" he pointed a random direction, hoping not to fight you, yet
