Sherlock Little Mermaid type AU where merlock feels strange things for the depressed naval captain he saved from a shipwreck and Moriarty the sea witch gives him a week to figure out why Watson is so interesting. Or maybe, like, same premise as Little Mermaid, but instead of mermaids and witches there are cyborgs and illegal hackers who can download AIs onto empty human minds. Or download humans onto empty cyborg shells. Anyway, I want Little Mermaid Sherlock. Think I can do it?
