On the following Christmas, during the Sycorax invasion, Harriet, having been elected as Prime Minister, was reunited with the nearly regenerated Tenth Doctor, having first met him in his previous incarnation. The Doctor proved to her that he was who he was by telling of when they were trapped in Downing Street, that the one thing that scared her wasn't the aliens nor the possible nuclear war, instead it was the thought of her mother being on her own.
