"How does a teenager get a lot of concussions?" Elliot asked, and sighed. "I can't make you stay, but you have to promise not to leave your bed unless it's necessary and to come right back in here for any vomiting, any dizziness, any additional pain. Though at seven if you go up, you'll probably be screaming so loud half the dorm will come running."

She went over to a cabinet. "I'm going to send you home with some painkillers and some antibiotic cream for the wound."
