She certainly splashes... at him. He's very big, though, and the spray only makes it as far as his shins, crouched in the water as he is. And maybe he can't speak, but he can laugh, a rough and surprisingly high sound for such a large creature but clearly laughter.

It's hard to see the cloud of dark mist that marks his transformation in the already-dark lake, but the glint of light off of his colorless scales vanishes. After a beat, the darkness clears, shrunken down to reform into a tall old man with colorless skin and the same eyes, blue, one clouded over as if blind. "This might be a little more fair," he says, and splashes with his hands instead of a tail.
