Bridgerton is one of the most popular TV shows on Netflix, but it will have to break one of the streamer's toughest records in order to give all of the Bridgerton siblings their own seasons.
Earlier in the season, Billy (Joe Locke), known then only as a "mysterious teen," had pleaded with Agatha to accompany him on that journey. In Episode 5, his true identity is revealed as Wanda's son.
