The line

Adelaide went out and stopped outside Valery's mansion, put a hand on her face and calmed down for a moment. She got the scare of her life, for a moment she felt Valery would kill her.... 

Of course he wouldn't, as he was only demonstrating his authority. 

Something that Valery had never done before, not like today. Seeing how he acted, his look, his presence, even how she felt she was on the verge of death. That made him feel a deep relief and pride, many worries he felt went away before the intimidating and authoritative way his mistress acted. 

Valery is a soft vampire with her family and her people are part of her family. Valery has always been that nice little lady who takes care of her people handing out wreaths and caring for others. Valery treated her people in the best way. 

But that's something that has to be fixed and that's the difference between a young miss and the lady of the territory.
