This episode takes place in December 1913.
Miss Georgina has a teddy bear which she says she has had since she was 7. As she has just turned 18 the chronology means that she has had the bear since November 1903 at the latest. This would make her the owner of one of the first teddy bears, which didn't go into production until that year.
Debuts of Lesley-Anne Down as Georgina Worsley and Jacqueline Tong as Daisy Peel.
