Anita (Silence in the Library)
Anita was a human member of the archaeological crew that came to the Library in the 51st century.
When Miss Evangelista was killed and the crew listened to her data ghost, Anita recalled her grandfather's data ghost, who had kept talking about his shoelaces. (TV: Silence in the Library)
Along with Proper Dave and Other Dave, Anita was attacked by the Vashta Nerada which she realised after noticing she had two shadows. The Tenth Doctor tinted her visor as a way of potentially fooling the Vashta Nerada, which kept Anita alive for a longer period of time, even surviving longer than Other Dave (who was attacked after her). Despite knowing her fate was sealed, Anita tried to keep a brave face through the ordeal. Eventually, however, she was eaten, but because her helmet was already dark River Song and Strackman Lux thought that she was still alive as the Vashta Nerada figured out how to speak in her voice. The Doctor was the only one who realised she was dead as he noticed she only had one shadow afterwards, but kept the knowledge to himself in order to use it against the Vashta Nerada.
In confronting the swarm of Vashta Nerada, the Doctor told it he had really liked Anita, commenting, "She was brave even when she was crying, and she never gave in." Her death moved the Doctor to be angry and forceful in his demands to the Vashta Nerada. She was returned to life in the computer core after CAL and Doctor Moon had saved her and the rest of the team. (TV: Forest of the Dead)
