Christian was slightly disheartened by her response, but if Care of Magical Creatures was not where her heart wanted her to go, he supposed he could understand the lack of interest that she was projecting. He couldn't really blame her, either, given his extreme distaste in Quidditch. After his accident, he assumed people would be able to forgive him for groaning when they brought the subject up. Particularly if they mentioned that he and his brother owned Quality Quidditch Supplies. But, he would just remind them that it had been their father's fault, not theirs. Or, not Christian's, anyway. Apollo had almost undoubtedly had a hand in it.
He was, however, bemused when she skipped over his almost-question regarding her name. To be fair, he hadn't phrased it as a proper inquiry. But it was still slightly odd. "Well," he began, trying not to make it clear how confused he was. He was someone who tried to be open and kind to others, so he couldn't exactly write her off after one likely mistaken interaction. "I'll likely focus more on the family business. I would like to expand and purchase another store, but that will depend on what is doing well, and what's available," he explained.
It didn't take long for Christian to realize that he could very easily start rambling about it. Business was something he actually excelled in, even though his father wished Apollo had been more that sort. The heir to the family was meant to be, weren't they? Apparently that trope would not be applying to the Zabini boys.
"I don't want to be irritating about it," he began more calmly, "but I would really like to know what I should call you. If I see you again before graduation, I would rather not have to say some variant of 'Hey, you!' to get your attention."
