Held back

I personally think its good she held back. Our little lord is still wary of her, and has been around enough abuse. So as much as i would have enjoyed her beating the nannys ass, it makes more sense not too. MC is a recovering ppl pleaser and her prioritizing building a good relationship with the little lord and removing him from a traumatizing situation instead of making it more traumatizing (bc witnessing violence is just as traumatic esp since he is still skittish around the MC) is the more responsible thing as an adult.

I would like however if on a seperate occasions she does do more to the nanny when little lord isnt around and him find out after the fact that way he knows she will protect him when theyre together but also when they arent. This also allows showing protectiveness towards him without involving him in adult affairs.
