Half is sarcasm

"Well, do you at least understand the situation?" Terra asked when she finished applying first aid to Rain's wounds. 

"Yep, no problem," Rain said. "I need a few days off to heal properly, and you won't tell everyone the reason for that, aside from old age. Wait, won't that make her feel worse?"

After the shocking conclusion of the match, Terra carefully examined him, and the severity of his injuries became painfully apparent. Confirming the toll taken by the intense combat, Terra reported that Rain's jaw bore the signs of being half shattered.

Terra's examination didn't stop there. She discovered that Rain's ribs had taken a brutal beating, the impact of Sealyn's attacks leaving them completely broken as well. The internal damage went beyond the surface, as some of Rain's organs had also sustained injury. The extent of the harm hinted at the sheer force behind Sealyn's strikes and the intensity of the physical contest.
