Billy frowned when he heard that… was he being punished for some mistake? He didn't remember doing anything wrong or messing up during the mission. The others also looked a bit confused, but they probably couldn't question Edward's authority in front of Jean.
"Calm down, everyone, it is nothing like that," Edward said. "It is just… this isn't a topic that we should discuss away from home."
Edward was being creepily ambiguous, to the point where Billy was starting to get really suspicious and uncomfortable. In the end, Edward laughed and then shrugged. There was no point in hiding that, even Drew looked troubled. It was better to solve that matter right now instead of putting doubts in everyone's minds.
"I suppose it can't be helped…" Edward said. "I don't have male heirs, only one daughter. So, I was planning to make Billy take my place someday. He is a brilliant kid, after all."
