Из интервью Моффата:
Episode twelve ended with an almighty trio of cliffhangers. Can you tell us anything at all about episode 13?
"Well, there's going to be some light music and a short note of apology saying, 'The universe ended last week, we're really sorry, we don't know what you're doing here, didn't you get the message?'"
Will there be any kind of trailer for the Christmas special after the episode?
"After the 50 minutes of gentle music and weeping apology? Nope. The universe has ended."
