5. Who Is Dave?
Nobody knows! Well, Shona does and according to her Christmas itinerary she's finally decided to forgive him for whatever it is he's done. It must've been pretty serious to warrant his inclusion on her 'to do' list, though it's seemingly not serious enough for her to get around to doing it before her Game of Thrones marathon. She might just be really tedious and fell out with him after he forgot to take the bins out that morning or something. Either way it was certainly an intriguing insight into her character and a tantalising teaser that there's plenty more where that came from as far as Shona McCullough is concerned. Some have taken it as a suggestion that she might be joining the Doctor and Clara as a full time companion in Series 9 and guess what?
Here are 10 reasons why she should. It's probably not even worth trying to guess who Dave is because the possibilities are literally endless. In the meantime let's just say she's finally forgiven David Tennant for leaving.
