Toshiko Sato (Tosh to her friends) applied her scientific skills to the Torchwood 3 team, after having worked for UNIT. Beautiful, brilliant, yet insecure, much of Tosh's private life remains a mystery.
Biography
Early life
Toshiko was born in London in 1975. Her parents moved to Osaka, Japan, in 1977, then back to the UK in 1986 (when speaking Japanese she does not have a noticeable Osakan accent, however). Her Japanese-born grandfather (born 20th January 1920) was a decoder at Bletchley Park and her parents were in the RAF.
Later life
Career
Graduating with distinction from university in 1995, Toshiko got work with a government think tank, and then 5 years before the building exploding she was hired by the Torchwood Institute. This occured because Tosh stole the plans to make a Sonic Modulator and successfully built one which she wanted to trade to save her mother. She was arrested by UNIT then saved by Jack Harkness who offered her a job rather than her spending her life in UNIT confinement. (TW: Fragments). This was in 2005.(TW: Greeks Bearing Gifts) Toshiko met the Doctor in spring 2006 while examining an "alien pilot" in the mortuary at Albion Hospital. She was slightly hurt when the creature turned out to be alive. She was referred to as "Dr Sato". (DW: Aliens of London)
- It was not specified whether she was working for Torchwood, UNIT or both organisations at that time.
Personal life
Tosh has had a few known romantic liasons. Every year for a day, Torchwood 3, had woken up Tommy Brockless a young World War I veteran frozen in 1918. During the four years that Toshiko had been working for Torchwood she had developed a crush on him. (TW: To the Last Man)
Tosh always found Owen attractive. Despite this, Tosh had a lesbian affair, her first homosexual experience, (torchwood.org.uk) with "Mary", a female alien who tried to use their relationship to gain access to her technology, which Torchwood had previous confiscated. In order to gain Tosh's confidence the alien allowed her the use of a pendant which granted her the temporary power of telepathy. Tosh used the device to save the lives of a woman and her child, about to be murdered in a domestic incident, but she became suspicious of the device when its use gave her insight as to how her team mates regarded her. She destroyed the pendant following the defeat of her former lover, Mary. (TW: Greeks Bearing Gifts)
Later, during one of Tommy Brockless' yearly awakenings, the past and present time shifts began occur, which the uniformed thought of as "ghosts". To prevent a temporal catastrophe, Tosh and the team saw to it that Tommy returned to 1918, after the couple had a short sexual relationship. (TW: To the Last Man)
She fell in love with Adam Smith when he gave her memories that they were in love and when she was told this she still couldn't bring herself to take the amnesia pill until she realised it was the right thing to do. (TW: Adam)
Toshiko was personaly responsible for shutting down the pharmacy. She was extremly saddened when Owen was shot in the chest killing him. (TW: Reset)
