OMG look what I found AGAIN! Definitely from Season 2 going by the scarf! I’ve upped the bigger size here! Lots of info in this pic for example is that Russell Tovey as Sir Henry holding a gun behind Sherlock? And look at Moriarty!!! And Sherlock and John on the moor! All the feelings!!!
ETA: What I found earlier today: Sherlock S2 at Mipcom 2011 plus one S2 promo still.
