Andoh’s older version of Lady Danbury has, as she tells Kate Sharma, «lived a life.» By the time we encounter her in «Bridgerton,» she is a widow and a grande dame of society, bold and self-assured enough to intimidate pretty much everyone except the Queen. Her life is touched by tragedy, as when she watches her friend, Sarah Basset, die in childbirth, and Agatha ensures that Sarah’s son, Simon, later the Duke of Hastings, has a proper upbringing and a lifelong ally despite his horrible father. She also sponsors the family of her old friend, Mary Sharma, as they return to society. Over the first couple of «Bridgerton» seasons, she essentially becomes an honorary member of their extended family.
