Remus, for all how werewolves tended to be thought of, could be quite a patient teacher. Really, he would have been exceedingly good to remain at Hogwarts teaching DADA even if he needed a substitute every so often. He corrected mistakes gently, without trying to make Draco feel foolish, then ended up making a tiny cheat sheet that gave the conversions. He didn't think Draco would need it for long.

It was late when they wrapped up, and Remus leaned back, eyes closing. "I think you have it well enough to be trusted with a bit of Muggle money tomorrow when you go out. Just remember the woman from the soap shop - she can help you out if you get stuck or her husband. Little balding man who always looks like he could use a good meal or three - name of Roger."
