When Mary Jane briefly loses Justin while covering a dangerous school protest, her on-air cry of his name goes viral on social media. "#whoisjustin" is trending all of a sudden, and the tenuous couple must decide whether to embrace their moment in the spotlight and use all the attention to thwart young conservative blogger-turned-correspondent Dani Hollins’ rise. Meanwhile, the arrival of Frank, an old family friend of Helen and Paul's, stirs long-forgotten memories of a love triangle that clouded the early years of their marriage.
Kara’s discovery that Mary Jane is sleeping with Justin sends their friendship into a tailspin and upsets the power dynamic at the studio. Sensing there’s more to Mary Jane’s break up with Lee, Helen sends Niecy to New York to “check in” on MJ. Little does she know, Niecy has other plans to meet up with a match from a dating app.
