His mother died when he was 8 years old. He doesn't talk about it. Ever.
She's had the piercings since she was 17: she got them just to feel like she was in control of something in her body.
At the Latino high school, he was the victim of mild bullying for being a "weird foreigner." That's why he now reacts aggressively to any feeling of rejection.
