Because who doesn't love super powers? In a world where people with special abilities is common enough I'd love to see the cast with unique abilities. Not everyone wears their powers in their sleeve except everyone thinks Sherlock's ability is rather obvious - of course his way of reading others. Or...is it? (So...it would be nice to see a superpower AU where Sherlock's power isn't necessary telepathy or, rather, could be a darker form of it - can literally kill with his mind, for example).

Could be Sherlock/John established relationship or just friendship, just please give me some action scenes/good case fic.

As an after thought, of course Mycroft's abilities would be stalking keeping track of anyone he chooses to. Curiously enough or not Sherlock seems to be immune to this...
