@Mafiye I do to but Leviathan basically said she can't act the way she used to because of her high position now. Also certain things require different emotions. Think of it like her separating her professional persona from her personal persona
@Mafiye she's got a new responsibility and she should act accordingly, she can be herself when she's with her people otherwise she'll be taken advantage of and belittled. Just imagine you, a great demon and being belittled. Nah chat you gotta stay professional.
