For weeks now Clara has been questioning this new Doctor and wondering whether she should be travelling with him. He is not the same friendly, heroic Doctor she once knew and last week he pushed her too far. Yet the thrill of the danger, the excitement of travelling through the stars is too great and she seems to have made a startling decision to keep going, even against her better judgement and her relationship with Danny. The idea of travelling on the TARDIS being like a drug might have been laid on rather heavily in the episode but it does suggest an interesting path for Clara moving forward.

In has been a tumultuous relationship and she has arguably developed into one of the most well-rounded companions in the show's history. Wherever Clara goes next, it is sure to be a fascinating journey. It might also be the turning point for the Doctor, if he doesn't send Clara down the same dark path as him...
