When Savi and Joss’s free-spirited, open-minded and often absent mother, Janet, comes for an unexpected visit, she brings big news but also stirs up some long-simmering family tensions. Now that Karen realizes that Elizabeth Grey knew all along about her affair with Tom, she wonders if Elizabeth might have actually killed Tom because of her; and April questions whether she should tell her daughter she’s dating Richard, although she has yet to tell Richard about the return of her supposedly-dead husband.
