This was the biggest question I had going into Bad Sisters Season 2, the follow-up to Sharon Horgan's excellent 2022 how-dunnit about a family banding together to kill their sister's abusive husband.

"Bad Sisters," created by Sharon Horgan, Brett Baer, and Dave Finkel, and based on the Belgian series "Clan," was one such series, neatly wrapping up the eponymous Garvey sisters' story with ten episodes that premiered on Apple TV+ in 2022.

Sharon Horgan, Anne-Marie Duff, and the cast of “Bad Sisters” react to the shocking premiere twist—and tell us why it had to be done.
