Tim was an airman in the 1940s.
Tim attended the Kiss the Boys Goodbye Dance in 1941. There, Toshiko Sato approached him and his friends, asking who was the best navigator. George said it was Tim and added, "He can't fly for toffee, but at least when he goes down he'll know exactly where he is". Tim helped Toshiko by giving her the exact details of the day's sunrise, figures that he wrote down every day. Later, when Toshiko cut her hand, he bandaged it for her. (TV: Captain Jack Harkness)
