Harry

Harry was an old man who was a caretaker at a fun fair on the south coast of England. He had worked there all his life. Some time between the early 1980s and 2009 he adopted Eve, an alien from another world. In 2009 the fun fair was shut down and Eve kidnapped four homeless people. He met Rani Chandra, who had sneaked in to find out who Eve was. He later encountered Sarah Jane Smith and Clyde Langer, who were also put under Eve's control. After the past was sorted out by Eve's son in the future, Harry joined his adopted daughter and new friend to travel the universe despite his initial refusal due to his advanced age.
