Tony had grown up his whole life hearing about his dad. Dad was a genius. Dad was a hero. Dad's spells had helped win the war against Grindelwald. Dad had worked with the Boy Captain. Tony was supposed to be like his Dad one day.
Tony had decided a long time ago to never, ever be like his dad. He certainly was never going to have a kid in his eighties and then just leave him for the house elves to play with. Tony hated house elves. He had an ongoing war with the mansion house elves to see if he could block off their teleporting magic. So far he'd only slowed them down once. But that was better than most wizards could do. But Mom got mad if he made the house elves stay away and nothing got clean, so Tony had learned to enchant pieces of furniture to do the work for them. He was even learning to teach the furniture to talk. But since it made people say he was like his father, he made sure the talking ones kept quiet around other people. And the house elves.
Tony did not like his father, but he did have one hero: The Boy Captain. Not the Boy Who Lived, everyone was always on about the Boy Who Lived, but the only thing the Boy Who Lived had ever done was die and get back up again a couple of times, which Tony didn't think sounded that hard and which probably hadn't been done on purpose, anyway. But the Boy Captain had Done Things. He had been a boy around Tony's age, too young to be in Hogwarts just yet, and he had fought the war against Grindlewald while Albus Dumbledore was still licking his wounds and refusing to fight.
The Boy Captain had been the only successful result of the War Wizard program, an effort back during Grindelwald's conquest to make wizards strong enough to fight Grindelwald. The potion only worked on the very young, whose magic was still taking shape,
