Draco weaved a hand in his hair. "Bellatrix tried to break down Hermione's walls. She didn't know Hermione was a skilled Occlumens even then. She was a natural. I taught her the rest during our fifth year. Snape told me he was teaching Potter, but I knew Potter wouldn’t be able to master it. Someday before the Easter holidays, Hermione asked me what I knew about that kind of magic. I told her and taught her. It was amazing how good she was even without any lessons before. And she didn't even know."
