Evangelista

Miss Evangelista was one of the explorers on the expedition to the Library in the 51st century, to investigate its abandonment.

Biography
A young woman in her late teens or early twenties, Miss Evangelista was the personal assistant to Strackman Lux; she called herself his "personal everything". The clear implication was she was hired more for her looks than for her ability. She was considered dumb by other crew members such as Other Dave and Anita, who joked about her mistaking the escape pod for the toilet -- twice. She befriended Donna Noble, whom she thought was nice for not caring about her intelligence. She confided to Donna that she felt like the others felt she was stupid because of her looks; even her father had a low opinion of her intelligence, comparing it to plankton. The fact she had at first thought this was a good thing served to lower her feeling of self-worth even further.

After being rebuffed in her efforts to help her shipmates, Evangelista found a hidden passageway leading to a hidden part of the library. She tried to tell the others, but they ignored her, so she went to explore it by herself. This proved to be fatal, as she stepped into a swarm of Vashta Nerada. Evangelista had her flesh instantly stripped by the Vashta Nerada, leaving her barely enough time to emit a brief scream. A Data Ghost remained in her comm system and she remained conscious for minutes after her death. During this time, she exchanged words with Professor River Song and Donna until her consciousness faded away to the words "ice cream". Afterwards, Donna described her experience with Evangelista's data ghost as the most horrible experience of her life. (DW: Silence in the Library)

Evangelista had been saved to the hard-drive by CAL. Due to transcriptions errors, her face had been disfigured and her intelligence increased; she theorised that a decimal point had shifted in her IQ. Later, when Donna was "saved" and experiencing an idyllic family life, Evangelista convinced her the world of the hard drive was not real. When River Song's consciousness was transferred to the hard drive along with that of her shipmates, CAL restored Evangelista to her original appearance.To CAL's statement of being a clever girl, Miss Evangelista is heard to shout "aren't we all!" to get River Song's attention thus implying her intelligence remained. The team was then happily reunited in the data core, which CAL called a "good place now" now that the Doctor had fixed it. (DW: Forest of the Dead)

Behind the scenes

 * The character's full name is never revealed on screen. It is never explicitly indicated whether Evangelista is her given name or surname; given the unusual nature of some names in the episode -- i.e. River Song -- it could be either.
 * Evangelista's last words have occasionally been misinterpreted as "I scream." On the official BBC subtitling, her final words are, "I... Ice cream. Ice cream." Which is in keeping with her (initially) childlike demeanour.
