"Good." Remus could have pressed. But, this wasn't a time for pressing, even if he were inclined to do so. This was when one just nodded and accepted the answer, making note just observe and wait to see what the actions said above the words. "At least you were able to keep from being sick afterwards, far as I know, which is more than I can say about myself."
The topic switch to Peter drew a sigh. He knew he was fighting a losing battle with the people around him about giving his former friend a second chance. Didn't stop him from trying, of course. "You asked Severus to keep your brother away from Peter?"
Remus chuckled. "They very likely would. That's why I sent you the titles I did. Different perspectives. The one constant about the Dark Arts, and magic itself really, is that they aren't constant. The way a wizard thinks will affect the way he uses magic. It's personal, very personal. We call can use a different perspective on things to help us better understand our own." Hadn't he had an example of that just that morning?
"So, you've described Severus' methods as point and hex. What are the differences you see with Sirius? Or myself or Regulus for that matter. Even your father or Moody. Each of us approaches things differently."
