His mood was excellent entirely. And nothing was bringing it down. Voldemort was sitting at one end, but going before him had been relatively painless, and it was hard to be anything but happy when he was back together with Tracey. He kept his behavior perfect in front of those that mattered. On his way back from going before Voldemort, though, his father had caught his eye. And it was nothing to anyone else, but Zacharias knew what it meant - congratulations. Oh no, that was not just for having a beautiful date to the ball. No, his father knew they had shagged. Zach had no idea how his father was able to tell from walking properly up to the ruler and power of the kingdom. But he did.
At least that saved an uncomfortable conversation later. Of one variety.
His parents were perfectly taken care of, as far as Zach was concerned. There was rather little else he could have been doing at his age toward satisfying his father's eternal goal for him. He was behaving perfectly, so everything else was acceptable for them, for him to do. He didn't know what Tracey's parents wanted or expected of them, but Zach glanced at her again and smiled, not as widely as he wanted, due to their location, but he really didn't care what they wanted.
