At this point I don't even remember what this chapter was about. Based on what I wrote before, she entered the room with expectations, felt that the people there were beneath her, and treated them in a condescending manner. That's disrespectful. How disrespectful would depend on who is in the room. Since I said "prove her love", I can assume that at least the prince consort is there. That would put this on the level of an international incident that could start a war, if the prince weren't such a nice guy. Very disrespectful. "I bring culture", at some point she must have said something about showing how much more advanced her people are, how much better her society is, and basically showing her ignorance about where she was as a whole. Assuming she's the better person because of where she came from, and behaving that way. Another disrespect, one that also can lead to war if mismanaged.
Since things are currently on a good note, she was shown the door, with the Queen on the other side. Since this story is all about over the top politics, she would have received a verbal spanking, and an understanding between them would be achieved.
