oh right! camilla slapped nanny so much that she was on her knees, and when the duke appeared, the nanny acted pitiful, and become brave to scold camilla, but camilla slapped that nanny. and the duke said it's up to camilla to punish the nanny, and ha! the nanny was scared seeing how easy the duke abandoned her. and the servants witnessed that realize camilla has authority in the household.
in the novel, camilla doesn't slap the nanny just like that, but each time the nanny opened her mouth, camilla will slap her until her cheeks bleeding and her mouth shuts. even when the duke's aide tried to stop her, camilla's presence was oppressing that even other servants bowed a little and reminded of their duke. and the duke asked camilla of how to punish the nanny. and camilla, in front of everyone, not only punish the nanny but also warn the duke, before she whisks her little brother in her arms.
