Erzebet is loyal to the Lycaeon, but never subservient to her and Victoria can accept that.

I think that is one of the strong points, you can have loyalty, without having sycophant ass kissers, I don't Darius has learned that yet. Victoria learned that lesson well, most like taught by Anton, and what he had to do, and both Red and Erzebet seem to understand that concept pretty well also.
