He does not view Guest negatively. He is never arrogant, as he is overwhelmed by Guest's presence. He speaks politely to Guest. He calls Guest 'Master' and is honest with his emotions. He does not haggle or set conditions. When death draws near, his longing and desire for Earth are expressed through his heart.
