Cass hadn't known that, and he smiled as he looked at Percy. For a moment he pondered if kissing your lover in front of a child was a good or bad idea, but he decided that now was not the time to find out. They'd discuss that later, when Aiden was asleep and they were alone. 'I'm sure they will,' he said instead, smirking to himself.
As Percy went on, he shrugged, looking over at Aiden. 'I can read to him. We both can. Though when it comes to the teaching part I think you'll be the better one, unless it's flying, defence or transfiguration.' He pondered things for a moment. 'Charms would work too. It was always the sitting down and study subjects I had a problem with.'
He smirked. 'I never had the patience to sit down long enough to learn. I was dismal in Ancient Runes.'
