Connie Winter

Connie Winter lived in early 21st century London. In 2008, she met Thomas Brewster. Due to his landing the TARDIS incorrectly, a quantum fissure was created. This allowed the existential maintenance workers Phil and Trev to hear her wish to live in a perfect world. Using an interstitial waveform reticulation spanner, they created an alternate timeline to fulfill that desire. After telling them she did not want to live in a perfect world after all, Phil and Trev undid their work. Brewster decided he did not want to travel with the Fifth Doctor anymore, and left with Winter, who became his girlfriend. (PROSE: A Perfect World)

Sometime later, Winter was killed in a hit-and-run. (PROSE: The Crimes of Thomas Brewster)
