Against Dan's wishes, Roseanne forges ahead with wedding preparations, with Crystal revealing she's pregnant with Ed's child.

Thanksgiving brings four generations together to cope with a surprise announcement from Bev.

A Christmas Eve snowstorm scatters the Connors, with Roseanne and Jackie trapped at the Luch Box with Bev and Nana Mary, while Darlene takes shelter at David's and learns the truth about his home life.

The Connors' dysfunctional-family Thanksgiving finds Becky preparing the bird, Dan and Mark duking it out, and an absent-minded Nana Mary revealing Bev's secret about her marriage.

Egos clash when Jackie and Fred can't make a decision about their marriage. Fred is having what Dan calls the moment of clarity, a case of the jitters that affects some men just before the big day. But what's really bothering Fred is his belief that Jackie has feelings for someone she sees almost every day and whom she is always asking to come over and fix stuff, none other than Dan.

Thanksgiving is a real turkey at the Conner household when Roseanne gets alarming medical news she can't confirm with the pre-natal clinic, and Nana Mary arrives with a feeble husband on her arm -- then upsets Bev by discussing the two abortions Nana Mary had years ago.

While Nana Mary amuses Roseanne and Jackie with a box of their childhood treasures, Dan and his pals reluctantly play poker with Leon and Scott.

Darlene's wedding day brings unexpected tears, joy and tenderness as Dan is finally able to express his love to Darlene and the young couple's wedding vows bring Roseanne to tears.

The absence of Dan, a series of family squabbles, and a shocking revelation by Bev mar the Conners' first Thanksgiving as a rich and famous family, and they start to realize that money does not necessarily buy happiness.

Bev pays a visit to her free-spirited mom in search of answers, while Roseanne awaits Dan's return with trepidation, fearing he might not recognize the place -- or her new look.
