How does Chris respond to everyone's sudden interest in fraternities and sororities?

As the school year goes on, Chris seems thrilled to be at Emory, returning to his clean cut look, taking pride in his grades, and even talking excitedly about plans to go to law school. That summer, Chris works for his parents’ firm, and develops a flawless computer program, but refuses to tell his father how it works. Some of his darker qualities seem to intensify while he’s at college, and when his friends start joining fraternities and sororities, he pulls into himself and becomes more self-absorbed and impatient with social interaction. Chris finds these clubs shallow, exclusive, and lacking authenticity.
