The instant he saw the glass vial, Fenrir Greyback's eyes widened. His body arched instinctively, and the shackles binding his neck and limbs clattered repeatedly.
He screamed in terror, "What are you going to do?!"
That scream was absolutely genuine, not some "insincere" reaction meant to conceal his secret.
After so many experiments, he had now gained a rough understanding of Wizet's magical ability.
Even if he could not rival Voldemort, he had at least reached the level of a Hogwarts professor—one who taught a magical subject such as Transfiguration Class or Charms Class.
