@Maomao I mean.. the nanny gaining control over her faction is possible. She is still young and inexpirienced. The other girl is blo*** killer so they are polar opposites. One is empathetic and frail while the other is ruthless and strong. They really fit well together as his support in the blood cult. The one doing administrative work is the frail and wise one. The carrot so to speak. While the other is the whip of blood cult. Punishing when is necessary. He needs to father successors of Blood Cult with them to strenghten and unite it. Especially if he will write in its laws that children of each girl will need to work together for the Blood Cult. Essentially creating president and a prime minister. One to rule with strenght and the other to rule with wisdom by running internal administration.
