At Percy's attempt at a joke Hermione turned and gave him a contemptuous glare. "I would say that if the given reports are true that the politicians aren't the only rats that have been in the Ministry as of late." The more she processed the his poor attempt the more logical connections her mind made and suddenly grief was over taken by anger.
She placed the tea cup on the window ledge. "A rat, Percy," she turned her body full around and began to walk towards him her finger pointing at him indignantly. "It was a rat that ruined Harry's life in the first place. You're rat to be exact," she was fuming. "You're rat took Harry's parents from him. And some rat inside your precious Ministry took Harry from us."
