In the context, Jude can't tell if karked is some kind of future expletive, or the guy's name. It feels like he should know that--but he's forgotten so much of the last two years, a name with a face he only half-recognizes is small change.

At least if he's wrong, it's the kind of joke that can seem like it's done on purpose. "Hey Karked, I'm Jude." It's the kind of shit Charlie would say, just to make him roll his eyes, but rolling their eyes at bad jokes is better than talking about how one of them might die in a ditch with nobody knowing. Laying his pencil flat on the pad, he lets the sketches be done, and admits a bit of their purpose. "I'll at least keep you in mind," he promises, "next time something happens."
