Yu tended to avoid this floor for his own reasons, but as per his own instructions he was checking every floor he came across. That was when he saw someone he'd briefly met once or twice facing... another him? Oh, hell. He really should have suspected this by now, but for some reason this guy just screamed I WILL BRING YOU ALL PAIN if something angered him enough.

He stayed quiet for the time being, waiting to see what else would happen and hoping to the gods above and below that this guy doesn't reject his Shadow.
