Since The Conners season 6 seems set to feature a major Roseanne character's death, the spinoff is almost certain to finally bring back a fan-favorite figure as a result. Estelle Parsons’s Bev played a pivotal role in Roseanne’s original run, the show’s 2017 revival, and its subsequent spinoff, The Conners. However, she has already outlived her daughter Roseanne, and The Conners season 5, episode 8, “Of Missing Minds and Missing Fries,” revealed that she is battling severe dementia. In one of the most heartbreaking scenes of the series, Bev had to be reminded of Roseanne’s death by Jackie.
