That punch goes into the wall: good. He wants to bust up his own knuckles, Yunlan isn't going to stop him. He keeps his grip on Jiro's wrist, firm enough to discourage any more bright ideas about violence, and glares up into the guy's face. What is he, like, twenty? Younger?

Maybe this is hell, and for Yunlan's sins he gets to handle teenagers who are even worse rebellious little shitheads than he was at their age.

"Don't do stupid shit and I won't have to tell you what to do. What's your malfunction? You think you can pop a guy in the head with human fucking remains because he apologized for pissing you off? I take it back, I'm not sorry! You need to handle your own shit, Jiro."
