Bridgerton Season 4 Repeats A Troubling Daphne Trend 
Despite being a fan-favorite Netflix show, Bridgerton has faced a number of complaints over the years, and perhaps none has been as loud and persistent as the complaint about the treatment of eldest sister Daphne’s narrative arc throughout the show. Daphne was positioned as the protagonist of Season 1 as the first of the Bridgerton siblings to get married.
Her narrative significance declined significantly after that first season, however. While all the seasons of Bridgerton focus on one specific Bridgerton sibling (with some narrative overlap), Daphne is the only sibling who has been almost entirely removed from the show since the season that focused on her romantic arc.
Daphne And Anthony Are Both Missing From Season 4, Part 1

In Season 4, Part 1, Daphne was once again absent, and while that wasn’t all that surprising to audiences who have now grown accustomed to the character not being included in new episodes of the show, older brother Anthony and his wife Kate being missing from Season 4, Part 1 caused a considerably larger stir.
Anthony’s season was Season 2, and his romance with Kate has proven to be one of the most beloved overall in the fanbase. Kate and Anthony, respectively, represent some of the most popular characters in the entire show, and although Colin Bridgerton was the focus of season 3, this couple still managed to get plenty of attention.
Anthony And Kate Will Be In Part 2

Although many fans were sad that Anthony didn’t make an appearance in Season 4, Part 1, both Anthony and Kate are confirmed to be returning in Season 4, Part 2. For one, both Jonathan Bailey, who plays Anthony, and Simone Ashley, who plays Kate, are included in Netflix’s official cast guide on Tudum.
More compellingly, the couple has been shown in a Season 4, Part 2 trailer, which also offers viewers a brief glimpse at their baby. Thankfully, this means that Anthony and Kate will not be getting the exact same treatment as Daphne, as they will indeed be returning and (hopefully) will play a major role in Part 2.
