Bethan Foster was a woman from Chorley. Her son, Anthony, went to Cardiff University and lived at student accommodation at the Bay. Following the tsunami, she travelled to Cardiff to find Anthony and learn who was responsible for the poor emergency protocol.

She sat in on the inquiry and questioned Andy Davidson, director of the Disaster Recovery Committee. Whilst in Cardiff, she met Orr, who took Anthony's form for her several times. At the inquiry, Jack Harkness told her that Torchwood was responsible and Bethan switched out the retconned water, exposing Yvonne Hartman.

Following the inquiry, Yvonne offered Bethan retcon to forget her son. (AUDIO: A Mother's Son)
