For Dean, school is a joke, and its just a way to spend his time while waiting for his father to come back. He demonstrates this by not bringing book or anything else to class. He even calls the teacher "sweetheart". Dean starts out as the cool, mysterious, guy. He later makes out with Amanda in the Janitor's closet. By dating Amanda, he further increases his popularity. He and Sam still meet at lunch and talk in the halls. He also is still protective of Sam when he sees a bruise on Sam's face, and threatens to tear Dirk's lungs out.
