Okay, I get the mother's frustration with her son, but what the hell? She knows the helmet killed one boy, and she knows her son is continuing to be shocked with it, and she's not worried that it might kill him too? Or is that what she's actually hoping for so she doesn't have to suffer from her son's behavior anymore? And blaming McCoy for having to take him home? WHOSE kid is he? That's right, hers, which means for better or worse, he's HER responsibility. Maybe she should've taken the time he was at the clinic to find another place that could actually help him.
