She sounds like the type of girl Derrick would either love or hate. He really admires that sort of ambition and subtlety, especially in girls, but if its directed at him or the people he cares about, he will definitely not be able to stand her. I guess it depends on how she treated him first. If they were on good terms, I could see him being amused by her, and more likely to help her keep up that good girl image.
