I do see your point, old man, and there is logic to it. But to answer you, no, I'm not afraid I should succumb to his bally old seduction into dark arts, what, but that in order to continue fooling him, I shall have no choice but to cast spells and commit to memory methods of fighting that would inevitably come out in the heat of battle (assuming we are destined to do battle again, what). I'm not certain I could stomach myself if it came to that.

I say, it's not that I'm not willing to defend myself, or Hydra, or Sally-Anne or any of us, when called upon to do so. Nor that I'm not willing to learn anything from him, what. On the other hand, I've no wish to compromise my principles, which is of course what Professor Dolohov has planned for us all. Besides, I have what I consider to be jolly well sensible reasons not to subject myself to his scrutiny any more than necessary.
