PAGES: 285-287

After Harry fails to cast a Patronus, Hermione quickly realizes that Harry is still wearing the Horcrux locket, which could be affecting his ability to perform magic. She demands that Harry remove it. The moment Harry takes off the Horcrux, he feels an immense sense of relief. Harry is reassured that he has not been possessed and remains fully aware of all his actions. The trio agrees to take turns wearing the Horcrux to minimize its harmful effects, with Hermione taking the locket next.
