"I believe you are correct about not fearing his name, Mister Potter, and, he named himself after he left Hogwarts. Anyway, I believe it's time for you to rest for a while, those spells took a lot out of you, I'm told. I am impressed with the power you put into the floating spell, there is obviously a big difference between floating a feather, and a 30 stone beast like that troll. And I have to tell you, that, even though I'm sure you feel some measure of guilt for Quirrell's death, you shouldn't. He would have killed you without a second thought, and your actions saved your life, and doubtless many others that would have been lost had he succeeded in his mission."
