Excited for her upcoming nuptials, Lily asks Whitney to be her maid of honor and plan an engagement party for her and her fiancé, Neal. All the party planning stresses Whitney out causing sleepless nights, so Alex suggests that she go see her therapist, Dr. Price for some help -- but a prescribed solution causes even more mayhem. Meanwhile, Roxanne decides to take charge of her potential future and finds an unlikely support system in Mark.

When Alex refuses to share the password to his phone, Whitney, who believes that they should share everything, becomes upset. Deciding they both need some solo time, they each plan a night out without each other -- but when Whitney comes home early she finds Alex in a compromising position. Meanwhile, Lily and Neal move into their new apartment together, but Lily is nervous about being herself, specifically in the bathroom.
