Tasha Williams

Tasha Williams (WC: Case File - Stacey Facade) was a member of P.R.o.B.e. At the age of seven, she lost her mother to a disease, after which she was effectively raised by babysitters and nannies due to her father's obsession with his career. (PROSE: The Door We Forgot)

When Archie MacTavish died Tasha and Maxie took it in turns to buy Giles breakfast because they were worried about him. (WC: Case File - Manchester)

Giles suspected Tasha had something to do with Sir Andrew letting him withdraw his notice after Stacey Facade turned out to be an alien who seduced him. (WC: Case File - Stacey Facade)
