Tish Jones

Letitia "Tish" Jones was Martha Jones's sister. Thanks to, she was propelled into jobs far above her experience level in order to draw out her sister.

Childhood
Tish was the eldest daughter of Clive and Francine Jones and sister of Martha and Leo. Growing up, she developed a crush on a man who worked at an activity camp during a bad family holiday. (PROSE: The Pirate Loop) She used to play tennis in the back garden with Martha, insisting on being Serena whilst Martha was Venus Williams. (PROSE: Wishing Well)

When Francine invited guests to dinner, Tish and her sister were expected to "perform" for the guests by handing out nibbles while Francine bragged that Martha was going to be a leading surgeon. Martha hated the attention and it caused friction between her and Tish, who embraced the attention. (PROSE: The Pirate Loop)

Career
Tish witnessed the Royal Hope Hospital disappearing, and later attended her brother's birthday party. (TV: Smith and Jones)

She then became the head of PR for Richard Lazarus, who made himself look 40 years younger. After the experiment he seduced Tish on the roof of his lab, just as he was about to transform into a lifeforce-draining monster.

Fortunately Martha and the Tenth Doctor arrived in time to save her. After everyone had evacuated the lab, Lazarus escaped to a cathedral where he chased Martha and Tish to the top of the tower and tried to kill them but the Doctor saved them by killing the mutated form of Lazarus with soundwaves. (TV: The Lazarus Experiment)

She then began to work for Harold Saxon when he became Prime Minister. The fact was he only hired her so that he could get to Martha. (TV: The Sound of Drums)

The Year That Never Was
Tish spotted Vivien Rook making her way for an interview with Lucy Saxon, despite Tish's protests that she was not to be disturbed, Vivien wafted her away.

When Martha, the Doctor and Jack Harkness went on the run, Tish, along with her mother and father, were captured and brought to the Valiant. There, they witnessed the Toclafane invasion of Earth. (TV: The Sound of Drums)

One year later, Tish was working on the Valiant as a slave with her mum and dad. She and her family tried to break out and stop the Master but they failed at each attempt. She and the rest of her family were present when Martha was brought onto the Valiant, and the Doctor used the psychic power of the entire world to restore himself and defeat the Master.

Following the destruction of the paradox machine, and subsequent reversal of time, Tish and the rest of the Jones family were among the few who remembered the events of the Year That Never Was. (TV: Last of the Time Lords)
