“I don’t think he feels lonely in himself, but looking at him from the outside, he lives a very solitary, almost monastic existence, and he’s paid a high price for following through on his responsibility and his vow of protecting the world of wizard kind against the persecution of mortals, known as no-maj’s, muggles. So yeah, I think he’s on the right side of the law and the right side of morality, as far as he’s concerned with his ideology, but it’s a solitary place to be.”
