He reached with his left hand within his right arm's sleeve, and began pulling off his glove.

No matter what he was doing or what he was wearing, when in Adrien's presence, Val always wore a pair of long, black gloves that completely covered his hands and arms; in all these months, Adrien had never seen him take them off, not even to eat - leading him to a quiet assumption that Val felt uncomfortable without them, for reasons that were not for him to know. As Val took off the glove, he revealed a glowing blue line that ran along his arm, then tracing a ring around his wrist; the top of his hand was marked by a circle with a dot in the middle, from which five bright lines arose to highlight each finger. Adrien had no words to speak, and could only watch in awe. Never would he have imagined that Val had been suppressing this beautiful light just to continue living.
