- And then came back, then went away, then came back again.
- Maybe they took Andy and Jerry, too!
- Scrubs is what would have happened if the Conners were a wealthy upper-class family instead of lower/middle-class.
- The Big Bang Theory is what happened if Mark/Davids mother had been more nurturing.
- Except for the fact that his parent in The Big Bang Theory was anything, but nurturing.
- Maybe David channeled his rage at Mrs. Healy's neglect into physics instead of the arts.
- Reba is what would happen if Roseanne and Dan got divorced.
A certain amount of Fridge Logic suggests that David and Mark have a different father than the two younger siblings. In Season 5, when David tells Darlene he's running away, it's because his "parents" (it's not out of the realm of possibility for David to think of a step-dad as his "dad" if his mother re-married when he was very young) are getting a divorce. This is why the girls go to live with their father but David has to stay with his mother. It also explains why she's so angry and abusive toward him. She says "You're abandoning me, just like your father," then verbally abuses him in front of Roseanne. David reminds her of her low-life ex, which fuels her abusive personality. Even later, when Mark shows David how to tie his tie for the wedding and says their dad did nothing for them. But in David's earlier appearances, his "dad" (or possibly step-dad) is a buffer between David and his mother. He can't put up with her, either, which is why he leaves, but why would he abandon David to her if David were his biological son?
- It also explains why he allowed Mark to be kicked out of the house, as also discussed in the tie scene. Not his kid, not his problem.
- This is apparently confirmed.
- He didn't die and they did not win the lottery, but Roseanne actually did write the book shown at the end of the finale. The last few minutes is actually the ending of the book, which Dan lampshades about having been killed off.
- They basically already did by the end of the second episode.
- Sub-guess: On a long enough timeline, Mark will wear the Chicken Shirt.
- It's also possible he'll simply grow out of wearing girls' clothes, particularly if he ages enough in the role that they want to start marketing his actor as a Teen Idol.
- Since Season 9 has been retconned, it's possible that the 2018 Harris is a different child than the one Darlene had during that season, and the only similarity is the name. Perhaps Darlene miscarried following her marriage to David in Season 8, and had Harris years later. Or Darlene has an eldest THIRD child that's off somewhere like Jerry and Andy.
- And the show will then be based around Roseanne’s death.
Or...
- In the revival, DJ said that he’s seeing a therapist (for his PTSD?) and he has been struggling ever since he returned from the army. Also, Darlene made a joke in "Go Cubs" that he’s seeing patterns, and DJ didn’t respond.
- He hasn’t been mentioned in the revival, and if he does get mentioned in "The Connors", it could be explained as this.
