Alex Kingston Q&A at the Florida SuperCon (July 2012): [X]
Are Doctor Who and River Song actually married?
Personally, I don’t think that they are, but you and I both know that trying to guess a Doctor Who plot line is similar to picking lottery numbers.
Was his name the only words whispered at the wedding?
Probably not, the writers are better than that!
Kingston also shared that the writer/producer Steven Moffat is working on who is River’s first doctor!
Was the Doctor being impersonated in the Teselecta (as River song mentioned) or did he truly ‘die’?
Unfortunately, I think this is the last for Matt Smith because BBC is already casting for their next Doctor.
