How you and Percy never met at the half-blood camp was beyond ridiculous, because you two know each other. Just in the normal, mortal world. When the both of you are in school. You got two brothers, and they play hockey, just like Percy does. So it was no wonder they set up a party after they won a game. The party was at your house, since your brothers planned it out.

You were going down from your room into the kitchen for some water, now under any other circumstances you wouldn't pay mind to the other players, but there he was. Percy. Your great rival.
