Claire Brown

Claire was a woman who, as the Thirteenth Doctor noted, didn't seem too sure of her past.

Biography
Claire bumped into the Doctor and Yasmin Khan on Granger Street in Anfield on 31 October 2021, where she claimed that they had met before and that she was "taking the long way home".

Claire returned to her house where she was stalked by a Weeping Angel. As she attempted to unlock the door, she blinked, and found herself in another time, another place. (TV: The Halloween Apocalypse)
