Hyperion shook his head sadly, thinking of how frightened the girl's parents had been when the child had been rushed into the hospital, and how delighted Macnair had been at the fact that he'd injured someone. "I don't kill people if I don't have to," he said firmly. "Even if I want to sometimes."
He smiled at her and nodded - she wasn't even trying to disguise who she was at this point obviously. But he also wanted to show that he could be civil and friendly, even if she didn't know that he knew who she was. For a moment he nearly broke down and told her, the labyrinthine nature of the exchange reminding him uncomfortably of their father. "We can know only that we know nothing. And that is the highest degree of human wisdom," he replied with a smile, wondering if she'd pick up on the Tolstoy quote.
"Thank you," he replied, flashing her a dazzling smile. He was fairly certain he caught the whiff of a genuine smile of her lips, and felt quite smug as a result. If he could make her smile then maybe, just maybe she wasn't as irredeemable as their mother would have him and his siblings believe.
He nodded thoughtfully at her words, finding that he was thoroughly enjoying the situation. "My grandfather has a pensieve in his house, and I was thinking of one similar to that? I can do the rune work myself if it's easier, but otherwise I can owl a drawing along?" He nodded thoughtfully about the razor and then grinned impishly. "I was thinking taking a normal muggle Rolex and charming it so it can show normal Muggle time, but also constellatory time. What do you think?"
