Much of Lupine's description, even before he reveals his lycanthropy to Harry, focuses on his physical appearance, mental health, and socioeconomic status, all of which his lycanthropy has a serious impact. When Lupine first appeared in the series in Harry Potter and the Prisoner of Azkaban, he “wore an extremely worn set of wizard's robes that had been mended in several places. He looked sick and exhausted. Although she was quite young, her light brown hair was flecked with gray” (Rowling 74). In this scene he was sleeping and his name had not yet been revealed. He was also on the train to Hogwarts with the students, although no other professor ever took the Hogwarts Express in the entire series. The first thing we learned about Lupine, then, was that he was fundamentally different from other wizards. We are not told why, but his shabby clothes, illness, tiredness, gray hair at a young age, and riding the Hogwarts Express with students already indicate a low socioeconomic status within the wizarding world accompanied by some sort of mental or physical discomfort.
