Warning: Spoilers ahead for Doctor Who season 15, episode 6, "The Interstellar Song Contest."Doctor Who season 15, episode 6, "The Interstellar Song Contest," introduces a new character called Rylan Clark, but there is a deceptively interesting story behind the co-host of the episode's titular contest. Rylan's addition to the Doctor Who season 15 cast places him in a fairly minor role, but one that indirectly leads to Ncuti Gatwa's Fifteenth Doctor being able to save the day. It would be forgivable for international audiences to assume Rylan's larger-than-life demeanor is an illusion put in place for Doctor Who, but they would be mostly wrong.
