"Exactly what I think ... and Hermione's most dangerous weapon always was her knowledge, her beautiful brain," Harry agreed, ruefully. "And they tried to take that away from her, by targeting her body. These are like delayed-reaction injuries, Enola ... painful on impact, but the effects dragged out until they run their full course, and allowing newer wounds on top as a result. Perversely, when we took the Restriction Enchantments away, we may have inadvertently made things worse in the short-term."
