"Maybe it can be reverse," she said. "I mean, it's fairly new. And there are tons of diseases out there that fade after time, or your body just takes over."
She watched him closely. "I had been thinking, they say the difference between Muggles and Wizards is that Muggles choose science over magic, at birth. They don't open themselves up to it." She raised her hands. "I'm working on theory, here. So, what if, it's like being reborn, and you continue to try to practice magic? Maybe it will find you again? Or... what if you were exposed to the same disease twice, would it reverse itself?" Lisa sighed a little. "Sorry. Just trying to be helpful. You can still work with a few potions, however, right? And there's always herbology, and magical creatures. Plus, there's plenty of work to be done with research or publishing."
Lisa tried her best to seem hopeful for him. She could only imagine how awful he must feel. "And if that doesn't work, I'll teach you how to deal with electricity." That, she was familiar with.
