Brendan Richards

Brendan Richards was the ward of Lavinia Smith. He first met Sarah Jane Smith during a school break in December 1981. Shortly afterwards, he was kidnapped and nearly sacrified by the Hecate Cult in Moreton Harwood but was saved by Sarah Jane and K-9 (KAC: A Girl's Best Friend)

His computer skills eventually led to him getting a job in the Silicon Valley region of San Francisco. He was unable to attend Lavinia's funeral as a result of his work in California (BFSJS: Comeback)
