Carrie Coon's conniving, scheming, take-no-prisoners socialite in HBO's "The Gilded Age" (all episodes now streaming on HBO Max) got everything she ever wanted by the end of the period drama's third season − everything except the devotion of her husband,

After a tense and dramatic third season, HBO ’s hit period drama, which follows New York City ’s high society in the 1800s, ended Sunday with railroad tycoon George Russell (Morgan Spector) walking out on his wife, Bertha Russell ( Carrie Coon ).

"What's at play there is somebody who's really in an existential crisis," Spector says of George in the season finale.
