Toshiko Sato's mother
From Tardis Wiki, the free Doctor Who reference
Toshiko Sato's mother, like her father, belonged to the RAF. (TW: Greeks Bearing Gifts) She suffered racial prejudice during World War II. (TW: Captain Jack Harkness) She gave birth to her daughter in London in 1975 but two years later, they moved to Osaka, Japan (TW: Greeks Bearing Gifts)
In 2005, she was kidnapped by Milton as a way for Milton to get her daughter work on a sonic modulator. Milton tested out the sonic modulator on her. (TW: Fragments) A vision (perhaps induced by Bilis Manger) of her mother with blood running down one side of her face urged Tosh to turn against Jack with the rest of the team and open the the Rift. (TW: End of Days)
- Given the appearance alongside ghosts in End of Days, it is impossible that Mrs Sato was killed by Milton in Fragments. However, Jack mentions that Tosh can contact her mother every once in a while.
