Nyx followed Calen with his eyes until he came back, holding a set of clothes for him to try on. That would be a first. He smiled, like a child who just received the toy of his dream and push himself out of the water, revealing the rest of his slender body, in all it's...nakedness.
Something that was easy to notice, was that Nyx was barely standing on his own two feet, he rarely went out of his river, so walking on two legs was also something new. Unaware of the uneasiness it could cause, he took the clothes and unfolded them, trying to figure out how to wear them.
Ending up with trying to put the pants over his head.
