Doctor Who - Prequel for the Bells of Saint John

It's become a bit of a tradition over the last couple of years for the BBC to produce short prequels to significant episodes like premieres, Christmas specials, and finales. Next week's mid-series premiere, "The Bells of Saint John", is no exception. In this prequel, the Doctor is feeling down during his search for Clara, and he gets a little pep-talk from a young girl. It's cutesy and you can see the ending coming from a mile away, but it's entertaining.
