(In this AU you still have you're abusive step dad, Gabe, after you're first quest with Annabeth and Grover)

You hated it when you had to leave camp when summer was over, you would try to make it as long as possible. After you're first summer you had to go home, go to a new school you would probably get expelled from, and get abused physically and mentally. So when you got back to camp you were super excited, you still wore a sweat shirt to cover up you're scars because no one knew you got abused, not even Grover and you were best friends. One day while you were swimming with them, you forgot a bit the scars, you were wearing some Navy blue swim shorts and no shirt, you were swimming with Clarisse, Annabeth, Grover, Travis, and Conner because Clarisse didn't hate you much anymore. Annabeth noticed the scars on you're back while you two were sitting on the dock.

"Hey percy, what are those scars?"
