What is the difference between Mark and Bryon

Mark has distinctive golden eyes and blond hair, like a lion. He has a demeanor of disarming innocence and wildness, since he is persuasive and can get away with anything. He also has no regard for laws or rules. He loves Bryon more than anyone in the world, considering him his only family left. However, he also has no sense of morality, and has no problem selling drugs to children. He becomes even more dangerous after he goes to jail at the end of the book. Brian is known for being a bit of a playboy, and yet really deeply falls for Cathy Carlson during the course of the book. While able to pick up girls easily, he can still be insecure about loyalties. He is deeply introspective and reflective, and a hard, diligent worker. He is also a good student. He has dark hair and a sturdy build, and is generally well liked.
