Training was progressing smoothly for both Hermione and Draco. Tom had had them doing various drills, pushing them to their limits physically, mentally, and emotionally. He taught them effective interrogation techniques, followed by ways to make captives break and exploit any and all cracks. Just when Hermione and Draco thought they had learned all they had needed to, more was thrust at them. Fights with conjured Inferi, one-on-one plus group battles with various accomplices; on some occasions Tom even had them fight each other.
