It's closing in on November (but there's plenty of October left). And with November will come the grand 50th anniversary of Doctor Who.
It will also give us a special meeting of Doctors in The Day of the Doctors.
The Day is set. November 23rd.
At long last it's time for the Doctor to face the Day. It's time for him to save it.
