Riza may have a really good reason to dislike Nityana, but she also has no affection for Cornelia (the insufferable, self-righteous, overbearing, not-my-mother, know-it-all) either. She likes both of her older brothers Mal and Nicholas.

The younger kids are just a petty annoyance. The ones who are closest in age, Nityana and Benjamin, are the ones she relates with the most and considers her closest rivals.

Don't forget, Malserrin, that I'm allowed to lowball my final stats by 20 for all four put together, and I'm going to make sure I'm not first rank in anything.
