I avidly followed all the #setlock reports and filming updates, it was exciting to finally see all these bits and pieces come together in the finished episodes. However, not all the moments fans saw filmed were used.
Interestingly, there was one particular moment of filming/photography that didn’t make it into any of the episodes or the minisode and yet adorns the inside cover of the series 3 DVD and the cover of the series 3 soundtrack. This was the image the BBCOne Twitter used to promote the beginning of the series on December 3rd and January 1st.
I think the BBC was letting us know the central thread linking these episodes. Those of us who were drawn to the vibe of unrequited love and longing (whether platonic or romantic) on Sherlock’s part throughout the series did so for a reason. It was the intended underlying theme of the series and was foreshadowed in this promo still.
