7. More Clara
Well, you didn't think you'd be able to get rid of her
that easily, did you? In fact, Jenna Coleman herself can't seem to make her bloody mind up about leaving. She was originally supposed to bid the TARDIS adieu at the end of
Death in Heaven before she had a last minute change of heart and asked to be included in the Christmas Special. As it turns out, she just can't stay away as she's been brought back for the whole of Series 9 which means that Clara's journey is only just beginning. Again. And what makes the umpteenth return of our impossible girl "game-changing", you ask? Well, most things involving Clara Oswald usually are. She jumped into the Doctor's time stream, for God's sake, before imprinting herself on all of his previous incarnations, and, as of
Listen, she is seemingly inadvertently responsible for making our titular Time Lord the man he is today. Blimey, Clara. Give someone else a chance.
