He'd thought he was being friendly, but he couldn't tell from Hyperion's response. His attempts at jokes really were pathetic and unfunny. So much for that type of social interaction with others. He pushed all of that, and Hyperion's comment about him having the ability to form an opinion, out of his mind. There was no point noting that of the two of them, Hyperion was not just anything. People respected Aurors, and the Wizengamot made actual decisions, whether or not they were respected. Unspeeakables were just... strange. And daft.

"I think a memo would work well," Zacharias said with a nod. "Thank you." He gave him a small smile of gratitude, aware in the back of his mind that he didn't know what else to talk about. He wasn't made for small talk. He wasn't born with that skill, and he hadn't been taught it, either. Maybe at some point his father had plans to transition him from seen and not heard to someone who could easily hold his own in a conversation, but, if so, he hadn't done so yet.
