When Julia's ex-boyfriend, Howard, is in town for the weekend, past and present worlds collide-new-baby stress meets IKEA mayhem, and Charlie's jealousy blows out of proportion. Julia's grateful for the escape-she's grappling with the exhaustion and identity-crises of new-motherhood and Howard's arrival stirs up nostalgia for her old life, a nostalgia that lingers and leaves her wondering, "Am I really happy?" In the meantime, Frankie has come to a realisation-she wants full custody of her and Charlie's eight-year-old daughter, Lou. What's more, Frankie makes the shocking discovery that her mother is having an affair with Bill, a married man.
