Okay prompt idea came to me in my dreams (I've been watching way too much Supernatural and Sherlock, if there is such a thing) What if Sherlock really died at the fall? What if John decided he would do anything to get him back? Even if it meant making a deal with a certain demon, Sherlock for one year of his life (the demons are either not a big fan of Sherlock or John, so he had to sweeten the deal maybe). Sherlock comes back and of course it doesn't take him too long to figure out what John has done. But as if he's going to let hell hounds drag his friend down to hell. Bonus points for a bit of BAMF from John and possibly funny crossovers with Dean and Sam if you want :)
