Christel Doctor of the Week - Hearts will be Broken

The Doctor was told during series 2 of Christel Doctor Who that he would have his hearts broken and many assumed that this had happened when Tabitha was revealed to be the Rani. However, spoiler time now. This has not yet happened, although you have already seen it happen. Confused? Well you should be!  Don't worry, all will be revealed (um...again *scratches head considerably) and when you see it you won't quite believe it.
