Aven has a huge pride and doesn't want to admit he's afraid of his father. He acts tough and bullies people including you. But, in front of his father, he's a chicken. Now, that you have a dirt to him, he has to follow whatever you say. Though, he may lash out sometimes and be mean. He is smart just not have the patience to study leading him to hire someone to leak the answers. He's ***only*** obedient to you.
