The emotion itself caused Hermione to freeze in shock. It had been a while since she had felt genuine fear before. It dredged up memories of the days when her father would come home drunk or when she was fighting for her life on the streets. She stiffened in annoyance and dipped her hand into her pocket. Bellatrix could disarm her in a second (that time in the company of Voldemort had been a one off, something that caused Hermione to look more skilled then she was) and Hermione needed a back up plan. Purebloods were so caught up in their ideas about magic being the be all, end all that they often forgot of Muggle weapons.
