The Demon of Illusion invaded his film-world and accidentally brought him to the real world temporarily until he was helped by the Charmed Ones and was placed back into the movie. During his brief stint in reality, Billy opened Phoebe's heart and she continues, presumably to this day, to watch the video of 'Kill It Before It Dies' that Prue bought her. Phoebe used make up to color Billy, as he had come into the real world just as he was in the movie (in black and white). Billy developed an attraction to Phoebe (which was more than reciprocated), but he eventually returned to be with his on-screen girlfriend, Sally Mae, back in the film-world.
