Behind the scenes
Trinity Wells was not named on-screen until TV: Turn Left. Before that, there had been much speculation over her name. It was later revealed by Russell T Davies that she was offically unnamed until series 2, when he finally decided to name the recurring character Trinity Wells.
The words "Mal Loup" (aka Bad Wolf) appeared captioning one of her news reports, but seem to be a manifestation of the Bad Wolf meme, as explored in TV: Turn Left, in which the word appears everywhere in many forms.
- Trinity Wells is one of only two characters, as well as the only named character, to have appeared in Doctor Who, Torchwood and The Sarah Jane Adventures. The other one is the French Newsreader, played by Anthony Debaeck.
- Apart from the Tenth Doctor, she is the only other character to have appeared in all of the first four series of Doctor Who from 2005 to 2010.
- Russell T Davies revealed in Doctor Who Confidential that he had originally planned for the Doctor to meet Trinity Wells in the special, but the scene was cut. In Doctor Who: The Writer's Tale, a full script for the scene can be read (in which Trinity reports of the destruction of Broadfell Prison and gives the Doctor information on Joshua Naismith). The reason for the scene being cut, as given in the book, is that Davies considered it to be "indulgent, and also shit."
