[i][b]Yes.[/b][/i] Keith didn't expect his words to even be understood, but that in itself was major improvement. Not only that, but he was overjoyed to find that intimate touching wasn't such a big deal anymore. He smiled widely, nodding his head to showcase how glad he was that he was understood, before gesturing at the merman to stay where he was. In a flash, the man got to his feet, ran straight back to his shack to gather his first aid tools. Once he was inside, he was glad to see the same rainbow reflecting off the abalone shell, even if the sun was setting. 

For a moment he stopped, watching the view, before he went back to searching in cupboards and his bathroom. When he'd gathered everything he needed, he quickly descended the stairs the way he came, and was back on the beach where he spotted the merman still sitting. He huffed, walking through the sand and eventually plopping down next to him again, a small grin on his face. "Hi," he hummed, as a short greeting, before the real work began. 

With the small bowl of water between his legs, Keith began to clean the cut on Shiro's shoulder, that particularly blaring red one. He applied some soap, get rid of the salt. The skin was rough and while the area that was wet wasn't as rough as the rest of the merman's body, it still felt foreign. [i]I could get used to it[/i], Keith thought to himself. On a small piece of cloth, he dropped some antibiotic ointment, watching until it formed a drop in the center of the piece. "Okay, this is where it hurts, Shiro," he murmured, before he slowly took the merman's hand. 

"You're gonna be okay," he said, looking at him with a nod and giving him a small reassuring squeeze in case he didn't understand his words, and ever so slowly, he placed the cloth on the wound, dabbing at it slowly for a few seconds before he quickly placed a bandage on the cut. Letting it air out was not a good idea, and honestly? Neither was placing a bandage. The water could wear it off, but at least it was better than leaving it exposed. "There. All done," he smiled, giving him a comforting pat on the shoulder where the bandage was and setting his stuff away for now to put them back later.
