Yamamoto had closed his eyes as he was lying there with his hands behind his head. He hears the growling noise, it is not unusual for Gokudera so he does not see the attempt to rid his mouth of sand.

He does open his eyes when he feels the shadow of Gokudera sitting up next to him, there is sand everywhere. And those scratches, that is not a good thing.

"Hold on, don't use your hands." Yamamoto rises in one motion, paying no mind to the sand on his skin as he jogs to his school bag. Opening it he shuffles around till he finds the shirt he wore in the choice battle. He does not see himself wearing a suit around Anchor. He also adds in some of the bandages and antiseptic he had left after fixing his own injuries on arrival. Back he trots, holding the package of the shirt, bandages and antiseptic out to Gokudera as he drops back to the sand.

"Here, you want to get the sand out, they don't look healed all the way yet." They aren't bleeding so they aren't brand new but close enough by Yamamoto's standards, infection is real Gokudera. The soft fabric of the shirt should hurt less than Gokudera's sandy fingers.
