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. Malcolm gave Sally a packet of letters and photographs from his grandmother. Sally read the letter, in which Kathy asked Sally to tell her brother Larry that Kathy loves him. Sally went to the bookstore where Larry works, and talked to him. She told Larry that his sister had gone on a trip when she had been transported to Hull in 1920 by the Weeping Angels. She saw a mysterious man on a TV screen that seemed to be replying to what she said. Larry explained that this man is on seventeens completely unrelated DVDs, and gives Sally a list of the DVDs.

Sally 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 an important bit of information: 'look at the list'. She sat with him on his last night of life, in a hospital.

Afterward, Sally looked at the list of seventeen DVDs, and realized their connection: they are all seventeen DVDs that she owns. She realized the messages on the DVDs were meant for her. She called Larry and told him to meet her at Wester Drumlins. They found the Weeping Angels and are warned by the Doctor not to blink, because the Angels move when they are not seen. On one of the DVDs, the Doctor told Sally about the Weeping Angels. Sally and Larry 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.
