Z watched Adam and the new professor snipe at each other. Nolan couldn't have been at Hogwarts for more than a few days at most and already he and Adam had issues. Or maybe it preceded his arrival? Nolan had an American accent-maybe this was drama from years ago. While Z normally would care very much about this information, right now she wanted Nolan gone so she could discuss things with Adam.
"Professor Nolan," Z said with just a touch of malice underneath her pleasant tone. "How very nice to meet you. And for you to so forwardly join us!" Z smiled politely at both men, then turned to Adam.
"I do so love when people drop into conversations unexpectedly, don't you? Now, Adam, since you seem to know the good professor, perhaps I should just have a quick bite with my good friend Nate Novarro and let you two catch up? I can come back before the end of lunch and chat with you then." Z very deliberately placed Adam's wand in her bag, knowing he'd understand that if she left, his wand was coming with her. She also knew he'd understand that she'd talk to Nate about the issues the two men clearly had-and then most of the school would know about it and be speculating wildly before the end of the day.
"Or," Z said, still sweetly but with ire lacing her words. "We can make polite small talk about nothing until fewer people are paying attention to us and Professor Nolan can make his excuses and leave and Adam and I can have a very necessary and dull conversation about ward theory."
