Sally Sparrow

Sally Sparrow visited Wester Drumlins and fought the Weeping Angels.

Biography
Sally was a photographer from London, whose hobby led her to Wester Drumlins one night. While taking photographs, she found strange messages addressed to her left by someone called the Doctor. She went to her close friend, Kathy Nightingale, for advice; this led her to meet Kathy's brother Larry for the first time. On a second visit to the house (with Kathy this time), Sally briefly met Malcolm Wainwright, who claimed to be Kathy's grandson. Baffled by this, Sally went to ask Kathy for an explanation, only to find that she had vanished from the area.

She also met Billy Shipton, a police officer, and he asked her out. Billy was sent by the Weeping Angels back to 1969 and given instructions from the Doctor to tell Sally important information. She sat with him on his last night of life, in hospital.

She told Larry that his sister had gone on a trip when she had been transported to Hull in 1920 by the Weeping Angels. He and Sally found and trapped the Weeping Angels and returned the TARDIS to the Doctor and Martha.

Afterwards, Sally and Larry began running a book-and-DVD store together; while Larry wanted to pursue a relationship, Sally remained distant as she compiled detailed notes of her experience, knowing that one day she would meet the Doctor. Some time later, she met the Doctor and Martha in person and delivered her important package of information. Only then did she finally allow herself to pursue a relationship with Larry. (DW: Blink)

An earlier encounter with the Doctor?
There is a possibly apocryphal account that, in childhood, Sally encountered an earlier incarnation of the Doctor and shared an adventure with him (also using pre-recorded messages). Assuming this is the same Sally Sparrow, it would appear both she and the Doctor have for some reason forgotten this earlier encounter, or that it might have occurred in a negated timeline.

Behind the scenes

 * As originally planned, the final scene of Blink would have been established as taking place a year after the defeat of the angels. All references to this time frame, however, were removed before broadcast.
 * Blink writer Steven Moffat originally created the character of Sally Sparrow for his short story "What I Did on My Christmas Holidays by Sally Sparrow", published in Doctor Who Annual 2006. This Ninth Doctor adventure (unusually sans Rose Tyler) depicted Sally as a young child who communicates with the Doctor via pre-recorded messages, much as she does in Blink. Due to the fact the TV episode is considered an adaptation of the short story, it is uncertain whether it can be considered canon.
