The Woman (The End of Time)
The Woman was first seen in a church on December 23rd. She told Wilf of the church's past; of how it was once a convent that it had been attacked by a demon from the skies in the 1300s, and was saved by a "saintly physician". After telling Wilfred Mott, that the physician may be needed again, she vanished.
She next appeared to Wilf on Christmas Day, her image appearing on television, which only Wilf could see. She told Wilf that he needed to take up arms, and that the Doctor's life could still be saved. Before vanishing again, she warned Wilf not to tell the Doctor of anything she'd said to him.

She had mannerisms similar to the White Guardian. Actress Claire Bloom had also been rumoured to play The Doctor's mother; going by the name, mysterious nature and the knowledge she has of the Doctor, this could be true.
