Sophia (The Storyteller)

Sophia was a young girl to whom Vicki would frequently tell stories of her travels with the First Doctor, Ian, Barbara and Steven. These same stories had previously been told to Sophia's mother when she was Sophia's age, but while her mother had quickly grown bored of them, Sophia emphatically had not, asking Vicki to tell her the story about the Daleks and Dracula again, and for her to do the voice of a Dalek while she did so.
