Re: Harry and Severus
"No, I wouldn't want him fighting," Severus replied. "But he - and people like him, the ones innocent of blood on their hands - are the reason I fight."
He thought over the last question, giving it its due. "He thinks I'm inventive; he inspires me to invent - I've already created a cure for Obliviation, because something he said to me once gave me the idea.
He admires me; in his presence, I try harder to be worthy of admiration."
