Lily Evans had no clue what Hogwarts was a few months ago, and yet she manages to be top of the class. James Potter is a rich kid with a talent for trouble, and yet still manages to be popular. Remus Lupin has an obvious secret, and yet he manages to find friends unobservant enough not to discover it for over a year. Sirius Black comes from a dark, ambitious family, and yet he somehow manages to end up in Gryffindor. Oh, and Peter's there too, I guess. (I don't own Harry Potter btw)
