The moment Morgana launched herself off Kasim's back, his attention was pulled toward her like a magnet. He treaded the water, his eyes on her face, studying her expression of pain. It bothered him that she hurt because of him, that because of his own choices, someone had gotten hurt, someone that shouldn't have. He put distance between them, only as far as their outstretched arms, and he made sure to tense his muscles so that Morgana could keep her head above water with his help. Then, when her transformation started, Kasim watched with obvious interest, his eyes going wide as he watched her legs begin to fuse together, as her skin rippled and changed from human skin to scales.
The midnight color of her tail glinted in the clear blue waters, rippling with the sun's rays like a thousand black diamonds. It was absolutely mesmerizing, watching her legs become a singular appendage, as her skin shifted and changed, and as she resumed her natural form. Kasim was forced to look away lest he try to reach for her while she was transforming, and risk losing an arm to her. Probably would be worth it for the five seconds it would take to reach across the space between them and worth it for the sensation of flesh touching scale, but probably wasn't really worth the risk of bleeding out or becoming Morgana's meal.
Rather, Kasim shifted to float on his back in the water, bobbing up and down with the waves. He nodded when she said she needed a moment, not trusting himself to speak. He was certain he'd say something insensitive or insulting, and then she really would eat him, injured or not.
He still held tight to her wrist, not letting her sink below the surface of the water. He was certain that if he let go of her, she would drown, and that wouldn't bode well. He stared at the azure sky, waiting for her signal to let him know that he could look, that he could actually begin to swim with her. He didn't want to push her before she was ready, after all.
