In which another Doctor

Standard warning for how I don't think Moffat is all that (at this point I just watch like one watches the depressing parts of the news - in order to keep up with current events rather than to enjoy oneself - and then I come here to rant about it because you just can't keep it bottled up) so if you do think he's all that or even half of that you probably just want to move along.
