Ceri (Forgotten Lives)
From Tardis Wiki, the free Doctor Who reference
Told by her mother that she was "not right in the head", Ceri lived on the streets and begged. In 2016, her consciousness was transferred by the Evolved into the body of Mr Griffith. She met and assisted Gwen Cooper and Rhys Williams, who helped get her back in her own body. (AUDIO: Forgotten Lives)
