Maria Dalton

In an alternate timeline in which the UK-201 never crashed on Dido,  was the daughter of Vicki Pallister and Jeran Dalton, together with her sister Carla Dalton (originally). Several modifications to the timeline by Vicki created further branching timelines which affected Maria's life.

First timeline
Maria's parents met when her grandfather, Newton Pallister, was killed by a meteor shower. Jeran comforted the grieving Vicki and in later years they married, eventually giving birth to two girls, Carla and Maria. Maria had blond hair and green eyes.

Maria grew up to work as a politician. Her party eventually put her forward for the position of governor. As governor, Maria was able to negotiate peace with rebel forces who launched a destructive campaign against the government on Astra. Her own sister had been killed at the start of the rebellion.

Second timeline
When Vicki learned she could modify her own timeline, she travelled back to prevent Carla from leaving for the Outer Provinces where she was killed. The rebels gained the upper hand in the new timeline. Maria was put forward for the position of governor by her party but she turned it down in favour of tackling the refugee crisis sparked by the growing rebellion. The new governor failed to negotiate with the rebels. Maria's family became refugees as the government stood on the cusp of surrender.

Third timeline
When Vicki's attempts to save her father ended poorly, she tried to meet Jeran again and return to her family life. However, very subtle changes to the course of events meant that Maria was born very different. She didn't have blond hair or green eyes and had an older brother named Carl rather than a sister named Carla. Vicki was horrified by the realisation that she could never see her daughter as she knew her again. This convinced her to return to the UK-201 's fateful flight and allow the prime timeline to play out.

Prime timeline
After Vicki escaped the alternate timeline and return to travelling with the First Doctor, Maria never existed. Vicki, however, could still remember her experiences and chose to preserve the memory of her family. (AUDIO: The Crash of the UK-201)
