Barbara allows a not-so-innocent flirtation with a surprising former flame to jeopardize her future with Darrell (Malcolm-Jamal Warner). Phoebe's life is flipped upside down when her estranged brother Tony (Steve Talley) knocks on her door and she must decide whether to let him back in. She also dips her toe back in the dating game and finds herself unexpectedly drawn to an enigmatic new acquaintance. After taking the pregnancy test, Delia evaluates her relationship with Paul (Ignacio Serrichio) and comes to an unexpected conclusion. Meanwhile, Jo finds that mixing business with pleasure comes with its own side of pros and cons. But the return of Jo's ex Frumpkis (Maury Sterling) from rehab ultimately tests the strength of her relationship with Albert (Brian Markinson). As the girlfriends each face the future and all of its unknowns, they lean on one another as they pave their own path to happily ever after.
