Theodore sipped at his tea as he let them talk for a moment, glad that they were conversing, even if it made Tracey a little bit uncomfortable. Although, he could tell that the discomfort was from the topic, and the memory of trying to break an Unbreakable Charm, not from Zach himself. He didn't really want to know the details of why that was a sensitive topic for her, but he could guess. His hand tightened reassuringly around hers, not quite as tightly as she was holding his, but enough to make sure she knew that he was there. He wasn't really thinking about it as anchoring her, but if it helped, that was all that really mattered.
"Someone should figure out how to cast Unbreakable Charms on bones," he mused vaguely. "Though, that would probably make certain people more reckless, so perhaps it's not the best idea. At least they're easy enough to fix, if you know how to do it properly."
He realized, belatedly, that his contribution could potentially be triggering as well. He found himself wondering what kind of evidence of injury her skeleton would show, and hoped that it wasn't as awful as he suspected it might be. She still moved gracefully, so that was something. Speaking of which-- "You know quite a bit about what Tracey does, too," he said with a smile. "Dancing. And singing, but she's only tried to teach me how to dance, thankfully. I've a feeling I'd be even more miserable at singing."
