Becca, Libby, and Paige have entered the ""man zone"". They tear down a wall in the Thatcher house to reveal another room, which is then redone (mainly by Paige) to be baby Nick's new room. Momentos from the old room lead to flashback-type scenes that reveal the changing roles of women in American society: Jesse and Becca as 60's hippies, Libby becoming a 50's Avon lady (with the Thatcher's as a 50's family), et al. Libby decides to leave Jerry's advertising firm to deal full-time with Nick. Paige discovers her true calling after finishing Nick's room-- she also wants to be a builder.
