Lucius gestured at Oswald, who looked like he was going to drop dead right then and there, he was pale and sweaty and ready to run. "If you're like me and you struggle, I think the best thing to do is to consider if that person would do the same things for you as you would do for them."

"I only have three friends." Lucius looked at Victor and frowned. "I think less is more."
