At the age of two, Lucy went to play on a slide for the first time. She went down the slide head-first, and was caught by her grandfather when she reached the bottom.
When Lucy was twelve, she and her family moved from London to Ogmore-by-Sea. There Lucy became friends with Hobo, a local boy who had alopecia. The two of them travelled to London to an event celebrating the life of Alistair Gordon Lethbridge-Stewart. The event was a trap by the Great Intelligence, and Lucy was able to defeat the entity with the help of Hobo and Dame Anne Bishop. (PROSE: Avatars of the Intelligence)
Lucy and Hobo travelled to Monknash to investigate the strange behaviour of its inhabitants. They discovered the behaviour was caused by the influence of Cylene, an alien matriarch. After stopping Cylene's sister, Sorene, from stranding her on the planet, Cylene was able to return home. (PROSE: The Midnight People)
Lucy and Hobo went to a video game arcade in Porthcawl. There they encountered a Quark. Lucy managed to pacify it as she was a descendant of its former master, Alistair Lethbridge-Stewart. (PROSE: The Arcade of Doom)
James Lethbridge-Stewart had memories of meeting Lucy and Hobo in Bledoe when he and Alistair were children. (PROSE: Night of the Intelligence) A photograph of that meeting was owned by Alistair up until his death, but he only realised it was here when she reached eleven. He told Conall about this in 2011, and in 2017 a time-travelling Lucy noticed the picture for the first time. (PROSE: Avatars of the Intelligence, Acceptance, and then Understanding) The events finally transpired in April 2018, when a time-travelling Alistair possessed the body of Hobo and Lucy and he was sent back to 1937 to solve the mystery of the Traveller. Lucy was helped by Alistair to accept his death, and to finally move on. At the end of the adventure, Lucy and Hobo used the time ring to attend her granddad's funeral in 2011.

When Lucy was isolating during a virus outbreak on 29 March 2020, she contacted Hobo on a website called Whoosh and encountered a group of aliens called the Meme Lords and defeated them. (PROSE: Copy/Paste)
According to one account, Hobo and Lucy eventually ended up as the last two rebellious survivors of humanity in a ruined London at "the end of the world", who were being hunted by the government while the Sun slowly imploded overhead. (PROSE: Assessment Day)
Lucy had dark skin and dark eyes, taking after her mother, Tamara. (PROSE: Lucy Wilson) She had wild hair. The personification of her grandfather told her that she had "the eyes" of a Lethbridge-Stewart, eyes that had seen wonders that others hadn't. (PROSE: Curse of the Mirror Clowns)
Lucy had a keen interest in aliens throughout her childhood, relishing in her grandfather's stories. Alistair himself believed she had spirit, much more so than any of his other descendants. (PROSE: Lucy Wilson) Lucy later adopted the alias "Lucy Lethbridge-Stewart", acknowledging her heritage and her mantle as a defender of Earth. (PROSE: Curse of the Mirror Clowns)
