The love between them
I don’t like S9 of Roseanne but Mark referring to Becky as Goldilocks (even though Becky was played by chalke during that season still)and DJ as Baby Bear was cute, and adorable.
Mark would call Becky: Becks, sweetheart, babe.
While Becky would call Mark: Honey, Big guy.
They had terms of endearment for each other. So people say their relationship wouldn’t have lasted since the whole Becky Wanting to go back to college problem, and Mark being against it but that was mostly his vulnerability coming to the surface.
Now going back a couple of seasons to Season 4 where we got to know more of his personality showed that he pretty much adores Becky like crazy, that she’s good for him. They became better people because of each other.
Mark was always supportive of her, and her decisions, and Visa versa with Becky wanting the best for him.
Also there were so adorable and cute in the episode where it was set in a 50s sitcom.
