Speaking of Shona, who is this Dave!? And what is she forgiving him for? He must be a pretty important figure in her life if he made on to her Christmas Day itinerary, albeit it at the very bottom and after her list of DVDs to watch. Surely it's a clue that there's more to come? Unless it just means she's finally decided to forgive David Tennant for leaving, but that might be a little too self-suggestive, even by Steven Moffat's standards. As always, only time-wimey will tell. At least she's got her Game of Thrones marathon to keep her busy in the meantime, anyway.
