Lancelot has nothing to fear, actually; this was actually a very finely-wrought attempt to appeal to Lancelot's sense of duty, such as it may be. Magnus figured Lancelot might get having some kind of code. "I know you guys have old-timey codes that are important to you, too," Magnus clarifies, just to be sure. "These crows I talked to in Flam were all about it, and Galahad has told me a little, too. Norman whatsits, right? So I imagine you get it. Vikings didn't really go for it though. But I, obviously, abide by Girl Code. And Bro Code. And Best Friend Code, and also Other Best Friend Code too I guess. So I suppose it's actually a network of codes. Codes all the way down."
