A girl dissolves, and reforms, for her own reasons.
They land in a bathroom, or perhaps a bathing-room. Luxurious, the size of a small pool or a very large hot tub. On opposite sides, one in the water and one out.
This water is so much warmer than the water she was in just a second ago!! Which is good because that was starting to get to her. And it's so bright in here!!!! She can see all of her new body even though her eyes are so much worse for seeing in the dark. She leans against the wall of the pool (with its straight straight smooth surface!!) and tries to pick up a foot to get a closer look at it. She falls over.
. . . he's too drunk for this. Where the hell is he. How did he end up here without anyone else except a naked girl. - A really young-looking girl, Jesus.
She gets a bunch of water up her nose. It's not pleasant.
But she can exhale it back out and then ✧look at her feet.✧
Her feet are very cool but even knowing humans need to breathe air she finds herself needing it sooner than she expected. She didn't have to dip back under the water that often as a mermaid. It's fine, she can swim to the surface, and gasp, and - okay, she's not really sure how to stand back up - this smooth smooth wall is very slippery and she can't grab onto it well enough to support her weight -
Okay yeah looks like it's time to go lend a helping hand. Won't do either of them any good if he falls in, though, so he walks around the edge of the water rather than running. He lies, belly-down, on the floor, and grabs at her arms until his grip is solid enough to set her on her feet.
". . . Kay. Hup." And he lifts her out, with considerable difficulty which is not helped by the fact that she's naked and also looks fifteen and he's going to get in so much legal trouble for the rest of his life if anyone sees this.
Thank fucking god there's a stack of towels over there. He unfolds one out and drops it over her, and then adds another one around her shoulders.
Weirdo. It's cute but there's way too much going on for him to appreciate it.
"So what's your deal, kid?"
