After the Northern army heads home, Dany hosts a feast in the ruins of Kings Landing. It's like the reverse of the Winterfell celebration, with Dany being celebrated and Jon feeling like an outsider. Dany calls for quiet and declares that Jon and Tyrion are traitors. As the Dothraki move towards them, the Dothraki and Unsullied begin to cough and choke. Arya has poisoned them all, Frey-style. As her army dies, Grey Worm pulls off his face and Arya declares that it's Dany who is the traitor. Any last words from the Dragon Queen?
Drogon thunders down into the banquet hall. Dany mounts him quickly while the others are stunned. Dany tells Jon, Arya, Tyrion and Davos that they will pay for this and starts flying to Winterfell to burn it to the ground. The others are helpless to intercede as even ravens wouldn't get there before Drogon.
Bran was been watching the whole thing through his freaky white eyes. He tells Sansa and Brienne what's coming. But he wargs into Drogon and forces Drogon to land peacefully inside Winterfell. Brienne takes Dany into custody. Jon, Tyrion, Arya and Davos arrive and hold a trial for Dany, accused of the slaughter of Kings Landing. She is found guilty. Arya offers to be the executioner, but Jon says that Ned taught him that if you condemn someone to die, you wield the sword yourself. Off with her head.
Dany gets her happy ending as they show the afterlife moment of her reunion with Khal Drogo and their child.
Last scene is a coronation of King Jon and a roundtable of who holds what keep. They get a white raven from Oldtown that spring has arrived.
