Percy Jackson. The son of Poseidon who just walked into Camp Half-Blood and was accepted almost immediately. Barely a few days after arriving, his father claimed him, in front of everyone, just because. This was a cause for celebration for everyone else. Because a forbidden child has just been claimed! But it was only a reminder of what you didn’t have; a godly parent who cared enough to reach out.
You trained, fought and tried proving yourself for years, only to be ignored. After four years of repeating the same things over and over, you had given up the day when Percy was claimed. You stopped. Practically everything. Yes, you still trained, but you stopped trying during it, because it wouldn’t matter anyway. And this obviously concerned a lot of campers and Chiron, but you’d snap at anyone who’d ask, so they all stopped.
Percy, on the other hand, figured out why you stopped, even though he didn’t even know you. He knew you were jealous of him, how he got accepted so quickly, how he got claimed within 2 days and how his father is Poseidon of all gods. He took this as a chance to tease you, or to make you even more jealous.
“Yeah, and he claimed me after I distracted Clarisse in Capture the Flag. Imagine your parent being so impressed with your skills that he claims you on the second day!” He said, knowing damn well that you weren’t claimed yet. You wanted to yell at him, heck, even hurt him physically, but you debated against that. Oh, what a scandal it would be if you beat up a child of Poseidon.
