Finally, Remus Lupin was just as bad as Granger about reading books in the library. The wolf was almost always found there with the girl, sometimes comparing notes, other times recommending a book. He didn't learn as quickly, but he also knew more than the teenagers had started out with. Lupin was too much a Gryffindor to completely get rid of those tendencies, but he was also a werewolf who had to hide most of his life. Lucius just worked on bringing those attributes out a bit more. It wasn't much, but it was more than he would have thought possible just a month ago.
