<P> At one point Jackie, unhappy with the self - absorbed couch potato Fred, starts going out with another couple, which then becomes one man . Dan sees her, warns her about Fred's possible reaction, but later accidentally blurts it out to Fred, who returns home upset, accuses Jackie of adultery and refuses to speak to her . With Bev's help, Roseanne has Fred realize that his accusations against Jackie are unjustified, and he returns to her . But at this point Jackie has realized that she's happier being single . The marriage is short - lived because Jackie finds Fred boring, petty, and self - centered and they fall out of love . Jackie is crushed by the divorce at first, but moves on to become a successful single mom to Andy . </P> <P> In Season 6, whilst Jackie is in labor, her mother Bev reveals to Jackie that her birth name is actually Marjorie and that the family began calling her Jackie because Roseanne couldn't pronounce Marjorie and instead called her "my Jackie ." However, in Season 10, Jackie introduces herself to Andrea, the woman looking to hire Becky as her surrogate, as Jacqueline . Despite Jackie's apparent flightiness in the early episodes, Jackie is actually the backbone of the Conner / Harris family in many ways, as Roseanne admits in the last episode of Season 9 . It is also revealed in that same episode that the character of Jackie had come out as a lesbian during the final season, and that Roseanne knew but had simply always pictured Jackie with a man . However, as most of Season 9 (and the final episode in particular) has been since ret - conned out of existence, this revelation may no longer be applicable . </P> <P> David Jacob "D.J." Conner is played by Michael Fishman (Sal Barone in the pilot episode). Born in 1981, David, better known by his initials D.J., was the youngest of Roseanne and Dan's children and their only son until the birth of Jerry Conner, in 1995 . D.J. is more simple - minded, naive, and boisterous than his older sisters, who frequently taunt him . In the first episode of season three, it is stated that while Becky and Darlene were planned pregnancies, D.J. was a "surprise". As he grows up, D.J.'s storylines deal with more mature topics such as masturbation and human sexuality . Later episodes depict D.J. as having a close, brother - like friendship with Becky's husband Mark . He is also shown to develop an interest in filmmaking: he repeatedly asks Darlene if he can videotape her giving birth . He was one of the only characters that wasn't changed in the final episode of Season 9, which has since been ret - conned out of existence . </P> <P> In Season 10, D.J. is shown to have recently retired from the military and returned home after serving in Syria for an unspecified amount of time . He is also shown to be married to a woman named Geena Williams, who is still serving in the military abroad, and that the two have a daughter, Mary . </P>
