Sherlock stared... What had been a fishman was now..a human? Or at least human in looks. John was half laying on the dock, naked at the say he was.. (were fishmen born?). At least there was no on else here to see him.

"You... have.. legs?" Sherlock asked, touching them softly. They looked and felt like normal human leg. "I'm not sure if you will be able to stand on them. if you aren't used to it."
