Roseanne viewers may have been a little confused after Tuesday's episode, "Eggs Over, Not Easy," when Becky found out her chances of ever getting pregnant are very slim. In a conversation with her sister, Darlene later, Becky says that she and Mark were trying to have kids but were never able to get pregnant before he died. Except in the original series finale, they talked about how they were pregnant.
Becky (then played by Sarah Chalke) and Mark were leaning over Harris's crib talking about their baby, which they were planning on revealing to everyone later because Becky wants this day to be about Darlene, since it's the day that premature baby Harris finally comes home from the hospital.
So what happened to that baby?
Well, the funny thing about the way the original Roseanne ended is that Roseanne revealed via a length voice over monologue that the show was actually a book she was writing, where she could change things around to "fix" things she didn't like.
In the "book," Dan was alive, Darlene was with David, Becky was with Mark and her mom was gay. In "reality," Dan died of a heart attack, Darlene was actually with Mark, Becky was actually with David and Jackie was the one who was gay, not Beverly.
The reboot has chosen to ignore that entire twist, with Dan never having died and the original couples that we watched all those years have continued as couples, at least for a while. So technically, the baby thing also should have been true. But the show has also chosen to ignore that as well. Becky certainly could have lost the baby, but presumably that would have come up during this episode about her fertility, so we're going with the idea that the show has basically ignored anything that happened in season nine altogether.
