Biography
After she joined UNIT, Shirley read the files about the Doctor and his ability to regenerate; she knew the appearances of the Doctor's tenth, eleventh, twelfth and thirteenth incarnations.

In late 2023, Shirley was tasked with evaluating the Meep's "crashed" ship at the Millson Wagner Steelworks, where she found the Fourteenth Doctor snooping around the facility and conducting an investigation of his own; Shirley interrupted the Doctor, and the two shared data on the crash while formally introducing themselves to one another. Shirley recognised the Doctor's face as belonging to their tenth incarnation. However, the Doctor indicated he knew the appearances of the three Doctors that followed the Tenth; this confused Shirley, who believed the Doctor was "forbidden" from knowing about his future selves. The Doctor then clarified and explained that he was actually the Thirteenth Doctor's successor, who had inexplicably gained a face and body near-identical to that of the Tenth Doctor. (TV: )
