Scars

It was a couple months after Percy came out of Tartarus that he started up school again. He was changing in the locker rooms for gym, he usually tried to get there early so people wouldn't see his scars from past battles, from hell, and in general from being a demigod. The mist doesn't hide scars, but of course he was late because his stupid math teacher held him after class because he got a F on his last math test. He ran into the room and dropped his bag on the floor.  Without thinking he took off his shirt and started digging through his bag to find his gym shirt. At first he didn't notice that it got quiet, everyone stopped talking and started staring at him. He cured under his breath. He had a large scar that started at his chest, went down his hip, and wrapped back up around his rib. He had another that looked like claw marks on his shoulder blade, and others that were smaller, scattered around his body. He stood up and turned to face his classmates. After an awkward silence one kid spoke up, " wh-what happened to you?" Percy clenched his jaw, "it's none of your business."
