It's nearly time to say goodbye.
On December 25, BBC America will air "The Time of the Doctor," a Doctor Who Christmas special that will mark Matt Smith's final episode as the main character of this beloved, long-lasting series.
Look for the installment to find the heroic Doctor grabbing Clara from her family dinner and heading off to investigate what a few enigmatic signals in the stars could possibly mean - and for them to end up having something significant for both his fate and that of mankind.
