Theo didn't know Ernie very well, but even so he thought that Ernie was made for being a Healer. He had the natural compassion, concern and diplomacy to steer someone ill into health again. "It'd be a loss to the Healing community if you left." he voiced before he re-registered what Ernie had said about meeting a guy to start a family. The bit that had Theo uncomfortable there was the last part, but not because he doubted that Ernie would be anything but a brilliant father to the kids of whoever he ended up being with. It reminded him that he was going to be the last of the Nott family, and that he had no business being anywhere near children even if he had plans otherwise; somewhere inside he was terrified that the rotten apple wouldn't fall far from the poisoned tree and that he'd become the monster to any potential kids he might have that his father had been to him. He didn't usually hold conversations that involved talking about children and the future so he rarely had the provocation to think about it. "But I think you'd make a good dad." he offered, trying to shake those thoughts away.
He was surprised at the question that came though, and had to bite back his knee-jerk response to say 'leave it'. He thought about it though, and while he had no ambition to speak of, his mind settled on one of the few things that made him happy anymore. "I'd like to work with thestrals somehow." he confessed.
