Aion tried to understand what made Malon get hurt… Cailena healed him in no time, so the damage had been only a single strained muscle. Since he didn't experience it, he couldn't be sure, and Malon was too stupid to even try to understand it.
"Straining muscles typically occurs when excessive stress or tension is placed on the muscle fibers, causing them to stretch or tear. There are several ways in which someone can strain their muscles," Aion thought. "Engaging in activities that require repetitive or prolonged muscle contractions, such as lifting heavy objects, performing intense physical exercise, or participating in sports without proper warm-up and conditioning, can lead to muscle strain. Pushing the muscles beyond their capacity or endurance can cause microscopic tears in the muscle fibers… he had been exercising for a while, so that isn't the reason."
