Sylvia first appeared in the serial The Forever War where she was saved and whisked away by The Doctor on her request as she did not want to go back to her hometown. She was held captive in The Plot by the Doctor's enemy The Master, and after trying to escape she was held up by a Dalek who attempted to exterminate her before she was rescued by The Doctor. In Monsters in the Water, she managed to save the sinking ship and the survivors on board from the Drashig. In Attack of the Spiders she met Adam, a survivor of an attack on the planet Skargoro. She developed a good friendship with him and promised him that they will take him away from the planet in the TARDIS and go travelling with them.
