WARNING: The following article contains spoilers for Game of Thrones Season 8 Episode 5.
The penultimate episode of Game of Thrones saw Daenerys Targaryen and her allies launch an all-out assault on King's Landing and Cersei Lannister for the Iron Throne and the right to rule over the Seven Kingdoms of Westeros. With Daenerys' forces depleted by the recent Battle of Winterfell, Cersei had bolstered her own with the Golden Company and Iron Fleet, so the playing field was relatively evened by the start of the Battle of King's Landing.
Despite the seemingly level odds, it was clear relatively quickly that Daenerys still held the advantage, obliterating the Iron Fleet and city's defenses, with her lone remaining dragon Drogon virtually single-handedly while breaching the walls of the city and incinerating the Golden Company with them. Despite the city's surrender, Daenerys and Grey Worm's own maddened thirsts for vengeance after the deaths of Rhaegal and Missandei in the previous episode led to the merciless slaughter of the innocents and surrendering Lannisters in the city and Red Keep.
The unquenchable drive for revenge was foreshadowed early in the episode by the death of Varys, Daenerys' longtime adviser. After learning that Varys had learned of Jon Snow's true parentage and sought to place him on the Iron Throne instead, Daenerys had Drogon burn Varys to a crisp for his act of treason and serve as a warning to those that would spread word of Jon's true identity as Aegon Targaryen.
As the battle spiraled into a chaotic massacre and most of the city was bathed in dragonfire, Jaime Lannister, embarked on a desperate mission to save his beloved sister from Daenerys' wrath. As he attempted to sneak into the Red Keep through Blackwater Bay, he was intercepted by Euron Greyjoy, wading ashore from the destruction of the Iron Fleet. After a bloody fistfight, the two stab each other grievously, apparently mortally wounding one another.
As the Unsullied entered the Red Keep, Cersei, Qyburn and the Mountain attempted to flee through the castle's back passages. While in flight, the Hound, who had snuck into the city before the battle with Arya Stark, catches up to them and challenges his undead brother to a fight. While Cersei and Qyburn commanded Ser Gregor to continue to protect them, the Mountain defied them for the opportunity to finally kill his brother, killing Qyburn and causing Cersei to leave the Clegane brothers to battle.
In one of the most brutal fights in the history of the entire series, the Mountain blinds his brother before being stabbed in the head. Seeing his brother survive the ghastly head wound, Sandor tackles Gregor through the battlements where they both tumble to their deaths below.
As Daenerys and Drogon continue their relentless attack on King's Landing and the Red Keep, Jaime and Cersei reunite and attempt to escape in the tunnels below the city. However, the resulting destruction of Red Keep causing the entire castle to collapse around them, Cersei and Jaime pledge their love for each other one last time and embrace before being buried in rubble, apparently killing the two Lannister siblings.
With the Battle of King's Landing leading to wholesale slaughter and wanton destruction, Cersei Lannister and her closest allies appear to have fallen, and Daenerys Targaryen has been established as the final villain in the fantasy series. With many of the major characters now dead, the final battle for Westeros will be internal one as the surviving characters face their new Mad Queen.
