A one shot set in Doctor Who season 4 episode 10 'midnight'. What if Jethro was actually Merlin in disguise killing time waiting for Arthur? What would his POV be?

These are oneshots from the TV shows Sherlock, Supernatural, Doctor Who, Merlin. Sometimes there will be SuperWhoLock crossovers. I am taking requests UNLESS I SPECIFY SO NONE OF THESE CHARACTERS OR WORLDS ARE MINE THEY ARE OWNED BY THE CREATORS/AUTHORS OF THE NAMED SHOW/BOOK/MOVIE
