Again, it’s not clear whether Kevin behaves differently with Franklin on purpose. Eva’s accusation that Kevin is trying to disrupt her marriage seems paranoid, but later in Kevin’s life, it does seem like he pretends to prefer Franklin over Eva, if only to spite his mother. It’s also possible that Kevin doesn’t like being around Eva because he senses that she doesn’t like being around him. Franklin gets upset with Eva for struggling with Kevin, but Franklin never offers to stay home with him in Eva’s place. Franklin believes in conventional gender roles, so perhaps it never occurs to him to stop working and stay home with his child because he considers childrearing women’s work.
