Toshiko Sato's mother
From Tardis Wiki, the free Doctor Who reference
Toshiko Sato's mother was kidnapped circa 2005 by Milton as a hostage 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 Toash to turn against Jack with the rest of the team and open the the Rift. (TW: End of Days)
- Her fate remains unknown. However it seemed implied that she died.
