Bridgerton Season 4 finally introduces Benedict Bridgerton’s love interest, Sophie Baek (Yerin Ha), and her backstory is further explored in episode 2. At one point, she gets called a “ward” by Lord Penward (Arthur Lee), and to us modern folk, some of us might be wondering what that regency used term actually means. Lord Penward then says that Sophie is his ward. What does a ward mean in Bridgerton Season 4? When Lord Penward died, Araminta told Sophie that she had been left nothing in his will.
