Sally Sparrow

Sally Sparrow is a human female and victim of the Chrono Slayer, who killed and erased her from history.

In the original timeline, she was instrumental in the defeat of a quartet of Weeping Angels.

Seeking to disrupt the Web of Time, the Chrononatrix sent the Chrono Slayer to eliminate her from the timeline.

As it turned out, though Sally's mark was wiped from history, she continued to exist after being slain in the form of a Neverperson, whom was absorbed into the Neverloff. When the Doctor Donna found her absorbed, her face was seen embedded into the Neverloff's side.
