You and Percy were playing Capture the Flag with the rest of the camp. You guys were the last two standing so everyone crowded around you to see the battle for the flag. You managed to get him down on the ground with your sword tactics but he overpowered you at the end when he used his powers of water to strike you down. After everyone walked away from the fight, you sat there in anger and defeat. He walked up to you and held his hand out.
