Talk about it here.
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) She and Leo once buried Martha up to her neck on Cromer Beach. (PROSE: Forever Autumn)
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)
In 2008, Tish helped plan Leo's twenty-first birthday party and told Martha to stop their father from bringing Annalise, whom she did not like and who she believed was frittering away their inheritance on fake tan. She witnessed the Royal Hope Hospital disappearing on her way to meet with Martha and waited, panicking, until it returned. At Leo's birthday party, an argument erupted which she blamed on Annalise. (TV: Smith and Jones)
Although she lacked experience, an interview panel got her the job as head of PR for Professor Richard Lazarus, who seduced her after his machine made him forty years younger. She was saved from him by Martha and the Tenth Doctor and was chased up Southwark Cathedral before the Doctor was able to kill the mutated Lazarus using sound waves. (TV: The Lazarus Experiment)
The Year That Never Was
Tish spotted Vivien Rook and attempted to keep her from interrupting the Prime Minister, but Vivien wafted her away and interviewed his wife, Lucy. When Martha went on the run with the Doctor and Jack Harkness, Tish and her parents were captured and taken to the Valiant, where 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 parents. They tried to break out and stop the Master, but failed at each attempt. They were present when Martha returned to the Valiant and the Doctor used the Archangel Network 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. Martha stopped travelling in the TARDIS, partly to look after them. (TV: Last of the Time Lords)
Tish did not like Annalise, believing that she was wasting hers and her siblings' inheritance on fake tan. (TV: Smith and Jones) As a child, she was always more willing to play up to her mother's expectations around her friends. (PROSE: The Pirate Loop)
The Master described Tish as "gorgeous". In reference to Tish, Vivien Rook observed that "Mr. Saxon" liked a "pretty face". (TV: The Sound of Drums) Richard Lazarus was also attracted to Tish. (TV: The Lazarus Experiment)
