Jason couldn't breathe. He was stuck underwater. He didn't know why. He, Piper, Annabeth, and Percy had been having a picnic. All of a sudden, he and Percy had attacked each other. Jason had pulled Percy by his neck and repeadeatley punched him, before Piper and Annabeth could stop them, Percy had thrown him into the nearby lake.  Jason was losing air, when Piper had jumped in and saved him. He had no idea how. "Piper, how did you?" Jason stuttered spewing out water. "I don't really know. I just told myself to." She replied confused at her own actions. Annabeth had Percy in a headlock and she was struggling to keep him from killing Jason. "STOP FIGHTING!" Piper screamed. Everyone froze. Percy dropped to the ground and Jason fell over. "I- i'm so sorry." Percy wheezed. "Me too man. I don't know what got over me." Jason sniffiled. Piper helped Jason to his feet when she felt something slimy on Jason's back. She examined the purple goop on her hand and exchanged a worried look with Annabeth. "What is this?" Piper freaked out splatting the goop on the floor. "I don't know. Let me get a closer look." Annabeth said examining the goop. "OH NO! THIS IS MIND POISON! IT MAKES PEOPLE FIGH-" Annabeth exclaimed as Piper knocked her over and slapped her across the face. Annabeth rolled over and kicked Piper in the stomach, hard. Piper than drew her dagger and threw it at Annabeth. It hit her side and Annabeth cried out in pain. Percy than jumped in front of Annabeth and blocked Piper. She stumbled back and Percy ran to help Annabeth. Annabeth than pulled the dagger out of her side and flung it at Piper. Piper ducked and Jason caught the blade in his hand. Percy than stood infront of Annabeth to shield her. Jason did the same to Piper. Suddenly, a bright light shone upon the four demigods. Hermes appeared from the sky. "Sorry. The Stoll's seem to have got their hands on my mind poison." Hermes spoke as he waved his hand over the demigods heads. When he had vanished, the goop had dissapeared and so had  the campers anger.

Not exactly a percabeth or jiper short but a crossover. Ily ;)
