Wouldn't it be hilarious if John Watson had some acquaintance with the supernatural already, and Sherlock didn't? So Sherlock would be frantically gathering data and adjusting his worldview, while John would just be like, "Yeah, that stuff happens."
Whoa, just had a vision of Murphy and Watson taking down some sort of giant evil Thing with practicality and guns. Ultimate badass mortal teamup! (And then they have sex.)
