"I suppose so," Claudius says, with a small, wavy hand gesture. "I suppose a great deal of diplomacy depends on what you want to use it for. For me, it's always involved sorting allies from enemies. Learning how to say the right words to the right people, who can fall into either category. Finding common ground and compromise, when possible, and making sure a disagreement doesn't erupt into further violence, when necessary. But in political affairs, friendships are hard to find. I rather respect someone like you who identifies and defends their friends easily. It's an asset." It's a very roundabout way of saying he's glad Galahad has a friend like Magnus.
