SHES LEAVING ON THE CHRISTMAS EPISODE
Think about it. Has Doctor Who ever had an episode where a companion has left because they’re SCARED of the Doctor? I haven’t watched enough Classic Who to answer my own question but they certainly have not in 2005+ Who. Moffat hinted at the Doctor and Clara’s relationship “dramatically changing”, and seeing how Capaldi is showing a much more unfriendlier and haunting side to the Doctor, maybe she’ll be uncomfortable enough to leave because she’s scared of him. She would be the first to leave since, just MAYBE, the whole situation with the Time Lord himself makes her repel away from him.
What do you think?
