Cathy O'Sullivan

Cathy O'Sullivan was the wife of Patrick O'Sullivan and the mother of the Eighth Doctor's companion Molly O'Sullivan (AUDIO: Tangled Web) and four boys (AUDIO: Fugitives).

While serving as a Voluntary Aid Detachment nursing assistant in France during World War I, Molly frequently wrote letters to her mother, who lived in London. (AUDIO: The Great War) After travelling to Dunkirk on 29 May 1940 in the TARDIS, Molly continued writing a letter which she was going to post to her mother prior to leaving her own time. She began to tell her mother of her trip to the future but ultimately abandoned the letter as the whole story sounded preposterous. (AUDIO: Fugitives)
