Madam Mo is taken aback, but rallies. "Who let him out!? Get rid of him!" she demands of the servants.
Her husband gives her a reassuring shoulder-pat and goes over to the intruder to remove him, but instead of holding still to be manhandled he drops to the floor. He grabs onto the floorboards with a strong enough grip that even when the servants get physically involved they can't pry him up.
"Damned madman!" the husband rages. "You'd better get back there right now or there'll be hell to pay!"
"I can leave if you want," the young man says, "but not until you give back what he stole!" He points to Madame Mo's son, Mo Ziyuan.
Mo Ziyuan's face goes pale with fear. "N-nonsense! When did I steal from you? What could I possibly gain by stealing from you?"
Mo Ziyuan's fine clothes and the intruder's tattered ones give him a reasonable point, but one that his guilty behavior belies.
"You didn't just steal from me, you beat me up and took my stuff!" the young man accuses.
Mo Ziyuan goes to kick him. He slips, but he may have connected beforehand, because the young man certainly rolls as if struck, and when he tugs his shirt open there is a distinct boot-print bruised into his flesh.
