In the new and the last episode of Game of Thrones, Jon and Davos survey the destruction Daenerys wrought on King’s Landing while Tyrion finds Jaime and Cersei’s corpses in the ruins of the Red Keep. Daenerys makes a speech in front of Unsullied and Dothraki, declaring that she will liberate not only Westeros, but the entire world.
Tyrion publicly resigns as Daenerys’ Hand in protest to her rule and is arrested. Both Arya and Tyrion warn Jon that Daenerys will have him and Sansa killed and the fate of Westeros is in his hands. Jon confronts Daenerys in the throne room and stabs and kills her when he sees she’s become a tyrant. Sensing Daenerys’ death, Drogon melts the Iron Throne with his breath and carries Daenerys’ body away.
The lords of Westeros convene to decide who will be the next ruler, and Tyrion suggests that future kings be picked by the lords of Westeros rather than through lineage. He also nominates Bran to be the next king under this new system, which the rest of the lords unanimously agree to.
Bran appoints Tyrion to be his Hand, allows the North to secede from the Seven Kingdoms, and says Jon is to rejoin the Night’s Watch as penance for killing Daenerys.
Afterwards, Grey Worm leads the Unsullied and Dothraki to Naath, Tyrion reorganizes the Small Council to rebuild King’s Landing, Bran goes off to search for Drogon, Arya decides to explore the uncharted seas west of Westeros, Sansa becomes Queen of the North, and Jon heads north of the Wall with the wildlings.
