User blog comment:Noctosphere/A demon I've heard about/@comment-27084975-20160908235656

Another reason why I'd like to see another Yellow-Eyed demon, is because in season 6, when Dean had an illusion of Azazel, he was very scared. I think its the same with Sam, both sam and dean have scar of what Azazel has done to their family. And I think they still fear Azazel might come back someday. So, a new Yellow-Eyed demon might bring back that scareness and make that demon a very powerful ennemy
