Custody

There is a girl. She has no name, nor does she have an age, causing frequent bullying at school. She has a shiny, red scar over the left part of her face. And though tested multiple times over and over, she has no ethnicity. For the past 10 years, her adoptive mother has been a drunkard. Her blood is a marble mix of purple and turquoise. The girl is exceptionally athletic, despite her malnourished appearance. In addition, she is so intelligent, that IQ tests cannot measure her points. She can read minds, and must rely on all her other senses, as she is blind. At school, she becomes friends with a boy named Mark. However something was off about this "Mark". His mind was quiet, as if he was meditating, and when his mind did speak, it spoke in an unidentifiable language. The girl wants to know. Who is this guy, and why is he so sophisticated? More importantly, can he help her find a name?
