The flowers Edmund picks for Violet are hyacinths. Their youngest child is named Hyacinth.
In the Book Simon Hastings also joins in for the pall-mall game. Here, he does not appear as Regé-Jean Page is no longer part of the Bridgerton ensemble.
The Pall Mall game gives Easter eggs about the books and each siblings order on the show. Daphne hits the ball through the first one, Kate and Anthony battle over the second, Colin tells Benedict that he is distracted and Colin goes third, then Benedict goes fourth and Eloise fifth.
In the show Anthony is with his father when he died. In the book the season is based on Anthony was not with his father, but came home and Daphne told him that Edmund had died.
