Even if Percy doesn’t entirely understand how capture the flag works at Camp Half-Blood, he is, like most others at camp, very interested in proving himself—something that comes along with being a demigod. In this way, Percy isn’t so different from anyone else at camp, even if he still feels somewhat lost and out of place. Further, Percy sees his role as a guard as a product of being low in the pecking order at camp, which makes him feel like the others aren’t his friends.
