Bruno was stronger than any fledgling not of his clan or the Gangrel. It was simply being a Brujah ghoul for decades. Joseph fed him extra, to guarantee the Frenchman had the vitae needed to make himself more powerful or heal if needed.
Joseph smiled. "I can teach you a bit if you like," he offered. "While you're not as strong as I can be, you're still stronger than a human. Everyone should know the basics of physical defense. Sometimes, you don't have time to use your magic." He had no doubt Rhys would become a formidable warlock. Henry had likely chosen him for his magical talent. But Joseph would feel better if that wasn't the only defense he had to rely on.
He leaned into Rhys' hand, lifting one of his to cover it. "You're stronger than you believe you are, Rhys," he assured him. "You would not have made it this far if you were not. Everything was against you. And you beat the odds. Sometimes survival is as much luck as determination. As I said, Fate sometimes gives us gifts we didn't anticipate. Those are often the best kind."
