While The Conners season 6 premiere was mostly a fun comeback for Roseanne’s spinoff, one major character was missing from the outing. After evolving from Roseanne into The Conners, a spinoff that focused on the show made due with a composite cast of characters from both the original series and the revival, minus Roseanne herself. Since losing Roseanne, The Conners has maintained a largely consistent cast of characters composed of Roseanne’s widower Dan, her sister Jackie, her children DJ, Becky, and Darlene, DJ’s daughter Mary, and Darlene’s children, Harris and Mark.
