The very beginning of the series starts on the killing fields of Afghanistan when Dr. Watson sustains a wound...or so it seems. Cut to his recovery in London and the early days where he lives in a small room, starts a blog, and visits his therapist. She asks about the progress on the blog and he says dismissively, "fine, fine, it's going quite well." "You haven't written a word, have you, John?" she answers. She explains how writing about all that happens to him will help him recover and help him not think so much about his injured leg and intermittent tremor in his hand (which she has diagnosed as psychosomatic). John answers, "Nothing ever happens to me." Quick cut to the credits and night scenes of London, the haunt of Sherlock Holmes.
