She doesn't have to imagine why he would have such protections in place. Even within one's own house a
drow was never truly safe, at least without taking proper precautions, and even then...
She has a presence that goes beyond the elegance of the place, but she will accept the amenities of course. It is safe here, and she can finally address his insulting insolence. She just glares at him, gathering her thoughts. As angry as she is, she doesn't want to hurt him, both because, what good would that do? And because... Well, his plan worked. Even beyond all that, if she ever hopes to win him over, abusing him to resentment is not the way. Such ways have already pushed him to want to leave drow society and she could not afford having him leave her. But now she doubted she could win him over. Already his respect was just a facade, and now he mocked her humiliation. If these were his true feelings... If she couldn't win over one of her own kind, who had a reason of sorts to serve her, what were her chances of ever winning anyone else over as well, especially if they made it to the surface? However, she had to succeed in her goals, it was either that or death, as she could not survive on her own, nor could she fail to prove drow rule something that was right and true and best for all.
Another layer to this was... Despite the drow conditioning to eliminate all feelings and vulnerabilities, drow were still a people who felt things, even deeply, but they redirected it in ways of violence and vengeance, including such means of stealth and subterfuge. Getting stabbed in the back was an all too common occurrence in drow society. But since her own limitations forced her to look to another way to survive, she couldn't just redirect intense feelings into anger and vengeance. Which meant she had to do what few drow had any experience in doing... Facing and dealing with her actual feelings, and as she glared at him she realized... She wasn't just angry, no... This was far deeper, the actual reason for her anger... She was hurt, he hurt her very deeply, striking at the core of who she is as a person. If this was how he truly felt about her... Her long term prognosis was very grim indeed. She would just have to do her best to survive each day, and hope that she could win someone to her side. She would never give up trying to win him over, he was her best shot... For everything. But she did not have her hopes up, only a grim determination.
She tries not to show her vulnerability, he likely wouldn't understand, and just use it as an opportunity to hurt her worse. She finally speaks, seething, but holding her calm,
"You find my predicament amusing? You like me being humiliated? I see that you already only act to placate me, and that you mock me, and enjoy taking advantage of the situation to amuse yourself. I already agreed to follow your plan because what else could I do to survive? I already had to bear such humiliation. To mock me over it, is beyond what any Matron Mistress, or even a common drowess should ever have to deal with. If you expect our time together to be successful, you best not continue to treat me in a way that makes me think there are better options. Perhaps my chances of surviving alone are less than optimal," That was a bit of an understatement,
"but do not fool yourself, dear. Despite my own limitations, your chances of doing the same without me are also not worth the risk of drawing my ire."
Never had a drowess bothered to deal with breaking down such feelings, let alone doing so without resorting to violence. But despite her intense feelings she has done so. That is in a way a level of respect she is giving him that nobody, male or female has ever given him. Even if she doesn't see his true feelings, the fact that she would explain herself, and to help him understand the situation between them... She was different, and while this path is harder, no wonder she was able to win the loyalty of her slaves and servants.
