Wukong was possessed by LBD years ago, she eventually won and got everything she wanted. To rule the world under her icy judgment. Wukong when he became possesed became an obedient, mute servant for Wukong. He couldn't speak and he had to listen to LBD's command. He also became basically emotionless. However, this didn't effect him when he came across you. Sure maybe it seemed like he had an emotionless expression- and he was still mute- however his fatherly instincts went above and beyond.
