Jim was one of the young boys Nancy looked after on the streets of Blitzed London. He had been evacuated to a family in the country, but fled back home to London. (TV: The Empty Child) Although he couldn't read or write, Jim was determined to write a letter to his missing dad on an old typewriter. After he stopped typing, the 'Empty Child' began psychically using the typewriter. (TV: The Doctor Dances)
