Moira

Moira was Bill Potts' foster mother following the death of her birth mother. The two of them lived together in a flat.

Moira had no permanent partner. Neville was her ex-boyfriend and Barry was Moira's friend.

Moira found pictures of Bill's birth mother in the back of a cupboard. When the flat was attacked by a sentient oil creature, Moira was with Neville again in the pub. Bill knew this because Moira called her on Neville's phone. (TV: The Pilot)
