Adriana Petrescu
Adriana Petrescu was a young woman who worked as a cleaner for "Joseph Serf".
Adriana worked for Joseph Serf as a cleaner, unaware he was a hologram. She was taken by a Skullion to the ground floor of the building she was cleaning. She saw that Skullions were being mistreated by John Harrison and tried to help, but was locked in a room. She was later joined by Sarah Jane Smith, who noted that Adriana's compassion for the Skullions — whom she referred to as the "Little People" — had restored her faith in human nature. They escaped and took the Skullions to the roof, where Mr Smith had arranged for a Skullion spaceship to pick them up. She met Luke Smith, Sky Smith, Clyde Langer and Rani Chandra there and they all witnessed the Skullions' return home.
She was given a Unified Intelligence Taskforce contact card by Sarah Jane, who said that they could use people like Adriana. Sarah Jane would ensure that Adriana would be paid well. (TV: The Man Who Never Was)
