In the conclusion of a two-part story (originally networkcast as an hour-long special), Sondra (Sabrina LeBeau) gives birth to twins, a boy and a girl, whom she names Nelson and Winnie (as in "Mandela"). Grandfather Cliff (Bill Cosby) is of course elated, but he's also worried that Sondra's husband Elvin will not be able to shoulder his new financial responsibilities--but Elvin has a surprise for all concerned. Meanwhile, Clarice (Phylicia Rashad) and Mrs. Tibedeaux (Marcella Lowry) adjust (sort of) to being grandmothers; and Theo (Malcolm-Jamal Warner) continues to be attracted to his pal Howard's girlfriend Julia (played by supermodel Naomi Campbell), which doesn't bother Howard (Roy Wilson) but certainly annoys Theo's girl Justine (Michelle Thomas). ~ Hal Erickson, Rovi
