The show has decided to write the actor's death into the 21-year gap since they last signed off.
Actor Glenn Quinn passed away in 2002 from an accidental drug overdose. With the revival of Roseanne, the producers decided to write his loss into the story, and it has already been mentioned on the show.
As reported by Inquisitr, Quinn played the role of Mark Healy, who, by the end of the series in 1997, was married to Roseanne Connor's daughter, Becky Connor.
The revival has only just hit the small-screen again, but after just four episodes, it has already taken a fairly serious turn.
The fourth episode, Eggs Over, Not Easy, addressed issues like infertility, and death.
In the episode, Becky, played by Lecy Goranson, discovered that she had only a 5% chance of getting pregnant, devastating news given that she had hoped to become a surrogate.
They also discussed the death of Becky's husband, Mark. and how much she was affected by his loss and struggling to cope.
In the episode, there was a moment when Becky spoke to her sister, Darlene (played by Sara Gilbert) and confessed that she and Mark had been desperately trying to have a baby.
She also spoke about how she would never find anyone as good as Mark.
When the episode ended, a photo of Quinn picture was shown on the screen, along with the words: “Dedicated to the loving memory of Glenn Quinn (1970-2002).”
Michael Fishman, who plays D.J. Fishman on the show, took to Twitter after the episode aired to share a tribute to Quinn. He also revealed that a photo of Quinn is prominently displayed in the hallway of the set.
Quinn originally joined the cast as a once-off guest as Becky's bad-boy boyfriend, but producers liked the actor so much they wanted to keep him on. Instead of a passing ship, Mark became a series regular until the end.
“We all missed Glenn so much, because he was just a great part of the show, and it’s not something we wanted to just gloss over,” Roseanne Barr explained of why the show discusses his whereabouts.
At this point, the show has not yet revealed when or how Mark died, but he certainly hasn't been forgotten by the cast or the fans.
