Sheila suffers from agoraphobia and is a fan of daytime television, especially "Countdown", finding it unbelievable that someone doesn't know who Carol Vorderman or Richard Whiteley are. She has a fixation with performing anal sexual acts upon Frank. She named her twins after two famous chefs, Delia Smith and Nigel Slater (although it is possible that the latter was named after Nigella Lawson). Sheila left with the twins to go on a cruise after discovering Frank had not divorced his former wife Monica (Annabelle Apsion), who had suddenly reappeared with her lesbian girlfriend.
