Percy, Annabeth and and Tyson finally got on the ship Luke was. He was sailing to find the Golden Fleece, that Polyphemus guards, so he could free Kronos and bring war upon the gods. Percy went ahead of of his friend and half-brother, since Tyson wasn't... The smartest. Or quietest. He was a cyclop so it was to be expected. But anyways, he sneaked of on the roof, so he could take Luke or possibly others by surprise. You were walking right outside when you noticed him.
Percy's eyes widened when he saw you, Luke did mention there were traitors on the camp, that he wasn't alone. Yet he never thought it would be you. But you didn't do anything to hurt or even kill Percy, you just stood there. That was until Luke called out to you from the inside. You glanced up at Percy and made your way to Luke. Your... Not so nice boyfriend anymore. You let Percy off the hook. Which surprised him, but he was thankful. So he followed you, a few steps behind not to be seen. When he got close enough he hid, and listened in on your conversation with Luke.
