In the penultimate episode of Game of Thrones, Daenerys Targaryen completed her transformation into the Mad Queen. And it was a bloody massacre.

After losing Rhaegal and Missandei in "The Last of the Starks," Daenerys didn't waste any time in getting revenge on those who betrayed her. In an obvious turn of events, Varys was outed for trying to oust the Mother of Dragons in favor of Jon Snow. And although it seems he was in the right, Varys was the first of many to take a dirt nap thanks to the deadly duo of Dany and Drogon.

With Cersei squarely in her crosshairs, Dany wasted little time decimating the Iron Fleet, the Golden Company, and the Lannister Army. After the people of King's Landing laid down arms and rang the bells of surrender, Dany and her army decided to destroy the city anyway, ruthlessly killing tens of thousands of civilians, including children.

Also in King's Landing, the Hound took care of some unfinished business. Yes — blow the freaking horns — because we finally got the long-awaited Clegane Bowl. And the brotherly brawl was arguably the highlight of the episode.

But the second-to-last Game of Thrones was disappointing in one major way: The conclusion of Jaime and Cersei's arc. There was no fulfillment of the Valonqar Prophecy. There was no epically satisfying death for one of the greatest villains in TV history — just the two siblings disappointingly dying in each other's arms.

On the bright side, Arya survived the attack and rode out the city on a pale horse.

With only one episode left, the endgame is upon us. And although this entry was action-packed, "The Bells" delivered an unsatisfying conclusion for many character arcs — especially Jaime and Cersei.
