Lucius didn't have to be a Leglimens to read what was going on in Draco's mind. His son was far too expressive. He really thought he'd taught him better than that. Still, he couldn't help but have pride in Draco's ability to control his emotions. He didn't burst out with whatever he was thinking, and that was a good step in the right direction as far as Lucius was concerned.
"I would be interested to hear where you think I fit in our new society." That was true enough, but Lucius also couldn't admit that he didn't know where he fit. He had no purpose, and his son was drifting away no matter what he did. "We are going to need support from the international community. I could start there, once we reach that point. As has been pointed out, we're a bit light in those with any sort of diplomatic experience." Aside from Severus, everyone here might as well be a child, Dumbledore included. Lucius wasn't sure he wanted to find out what, if any, influence he had left in the wider magical world, but if pressed it could be his contribution. "Now, why don't you tell me what Potter--excuse me, what you were thinking."
