Jaime Lannister pensively inspects the passing carriages loaded with Highgarden gold. Bronn questions his sulky attitude and asks when he’ll receive what he’s owed. Jaime tosses the sellsword a bag of coins, promising he’ll have his choice of castles when the war is won. Randyll Tarly, followed by his son Dickon, reports on the status of the stores and harvest also being loaded onto wagons.
In King’s Landing, Tycho Nestoris is impressed Cersei will be repaying her debt so quickly. Cersei mentions she will need to expand her military to reestablish control over Westeros, and Qyburn has reached out to the Golden Company in Essos for support. Seeing potential in Cersei’s future ventures, Tycho assures her the Iron Bank will also be happy to assist -- as soon as the gold arrives.
Within his Winterfell chambers, Bran sits in a new wheelchair as Littlefinger presents him with the dagger used in the attempt on Bran’s life. While Littlefinger rues he couldn't save Catelyn, Bran unsentimentally examines the blade. Finally, he asks Littlefinger if he knows to whom it belonged; Baelish responds he doesn’t -- the very question sparked the War of the Five Kings. Littlefinger’s speech about the chaos of the world is derailed when Bran looks directly at him and quotes, “Chaos is a ladder.”
Meera Reed enters Bran’s chambers to tell him although she doesn’t want to leave him, she feels she should be with her family. Bran agrees he no longer needs her. Heartbroken, Meera reminds him Jojen, Hodor and Summer all died to protect him, and she too put herself at risk. Meera realizes the Bran she knew died in the Three-Eyed Raven’s cave.
Arriving at the Winterfell gates, Arya has trouble convincing two young guards of her identity. They escort her into the courtyard, arguing which one will tell Lady Stark about the strange girl. Arya slips away unnoticed.
Sansa, sitting in Jon’s office, is unhappy her guards lost a stranger on the grounds. However, when she hears the girl asked for Ser Rodrik and Maester Luwin she realizes it is Arya, and knows exactly where to look.
Arya studies the statue of her father in the Winterfell crypt. Without turning, she acknowledges Sansa’s presence: “Do I have to call you ‘Lady Stark’ now?” The young women hold for a beat, before embracing. Arya downplays her new skills, and instead comments how unlike their father his statue looks. Inquiring whether Sansa murdered Joffrey, Arya reveals he was on her list of people to kill. Sansa laughs, not realizing the list is real. The sisters know they have long stories to share, and hug once again. Sansa pulls back to reveal another surprise: Bran is home, too. Arya lights up, but gathers from her sister’s face something is wrong.
Arya rushes to her little brother in the godswood and is mystified when he says he saw her at the crossroads. Sansa explains Bran has visions. Bran confirms the reality of Arya’s list when he says he thought she would be pursuing Cersei in King's Landing. Arya’s attention moves to the Valyrian steel blade on Bran’s lap. Once Sansa puts together what the dagger is, she wonders what Littlefinger expected in return from Bran. Remarking he has no interest in it anyway, Bran gives the blade to Arya.
The three surviving Stark children pass through the Winterfell courtyard. Looking on, Podrick tells Brienne she should be proud: She kept her vow. Littlefinger watches from above.
Arya comes upon Brienne training Podrick, and asks to be trained as well. Brienne offers to find the Master-at-Arms, but Arya insists she wants the person who beat the Hound. She points out Brienne’s oath applies to both of Catelyn’s daughters. Sansa, overhearing from the balcony, cannot conceal her expression from Littlefinger. Arya takes up Needle, while Brienne uses Oathkeeper, and the two women go at it. Arya's skill level surprises Brienne. The fight ends in a stalemate, both visibly pleased by the interaction. “Who taught you to do that?” Brienne asks. “No One,” Arya responds with a smile before staring after the departing Littlefinger.
Daenerys and Missandei make their way down to the Dragonstone beach. Missandei asks for news of the Unsullied, visibly disappointed there is still no word. Picking up something new in Missandei’s tone, Daenerys looks curiously at her friend, who begins to tell her about “everything” that happened. The women put their conversation on hold so Jon can lead them into a nearby cave.
Moving through small tunnels, Daenerys and Missandei look in awe at the walls covered in dragonglass. Jon brings Dany deeper, and they enter a smaller cave where Jon points out carvings on the wall: drawings of the Children of the Forest and First Men united against what is unmistakably the White Walkers.
Outside the cave, Tyrion and Varys hesitatingly tell their queen Casterly Rock has been taken. Dany doesn’t understand why the news appears to be unhappy. Once informed about Highgarden, the Dragon Queen angrily wonders if Tyrion has what it takes to fight his own family. Daenerys again considers flying her dragons to the Red Keep, and asks Jon’s advice. Initially hesitant to get involved, Jon watches the beasts flying overhead and suggests people who believe in Daenerys believe in her because she’s made the impossible real again; they have faith she can build a better world. Using her dragons to “melt cities and burn castles” would make her no different from those that came before. Weighing her choices, Dany too looks to the sky.
Davos teases Jon he’s noticed the King in the North staring at Dany's “good heart,” but Jon waves the comments off. Missandei is confused that Jon’s last name is “Snow”; in her homeland of Naath, there are no marriages, and thus, no bastards. The former slave girl is adamant her queen would allow her to leave whenever she wished. She reminds the men Daenerys is not their queen because of her name, but because she is who they chose. Jon smiles, until he notices a Greyjoy ship in the distance.
A small group of Ironborn, including Theon, alight onto the Dragonstone beach. Theon is genuinely shocked and ashamed to see Jon, and asks after Sansa. Jon makes it clear Sansa is the only reason Theon is still alive. When Theon explains he is in need of the queen’s help saving Yara, Jon tells him Daenerys is not currently at Dragonstone.
The Lannister wagon train makes its way through Blackwater Rush. Dickon Tarly confesses to Jaime and Bronn the battle at Highgarden was his first -- and it wasn’t what he expected. An unfamiliar sound rumbles in the distance, growing louder. Randyll and Jaime call their men into action as the Dothraki Screamers appear. Bronn urges Jaime to get himself to King’s Landing, but Jaime refuses. His perspective changes as Drogon hurtles towards the battlefield. From above, Dany issues one command: “Dracarys.” The Lannister line breaks in several places and the Dothraki rush in.
On Jaime’s orders, Bronn makes his way to Qyburn’s “scorpion,” but is waylaid by a Dothraki fighter. Jaime, in his own one-on-one fight, is saved by Dickon at the last second. Bronn climbs into the covered wagon with the weapon, shooting its first spear into his Dothraki opponent. He begins to load a second bolt into the device.
Overhead, Tyrion watches as Lannister men are slaughtered. His attention is pulled away when an eight-foot bolt flies past Drogon. Muttering to himself, Tyrion tries to will Daenerys away from Bronn and the “scorpion,” but the Queen of Dragons dives in at top speed. As Drogon opens his mouth, Bronn takes aim and shoots, hitting Drogon but barely escaping Drogon's flames himself.
Though hit, Drogon is not seriously injured. From their own perspectives, Tyrion and Jaime watch Drogon land near the river. Dany climbs down to remove the harpoon from his scales. Tyrion sees Jaime grab a nearby spear and charge the dismounted queen. Drogon swivels his head to attack until Bronn, riding in on his own horse, tackles Jaime. The two men fall into the river as Drogon’s flames engulf both horses. Underwater, Bronn and Jaime float alongside drowning and dead men whose armor weighs them down, while flames blaze above.
In the dragonglass mines, Jon shows Daenerys petroglyphs that prove the existence of the White Walkers, and that they were defeated by an alliance of the First Men and the Children of the Forest. The Iron Bank promises Cersei to support her claim once she pays her debts by the plundered gold from Highgarden. Jon dissuades Daenerys from attacking the Red Keep by herself. Instead, she takes Drogon and the Dothraki army and attacks Jaime's, defeating it and destroying the plunder. Bronn uses a ballista to wound Drogon, who destroys it before falling to the ground. Jaime fails to kill Daenerys before falling into a river. Meanwhile, Meera leaves Winterfell, receiving a cold goodbye by Brandon, whose apathy proves his complete turn into the Three-Eyed Raven. Baelish gives him the Valyrian steel dagger used to attack him after his fall. Arya returns and reunites with Sansa and Brandon, who gives the dagger to the former. She overpowers Brienne in a duel.
Arya returns to Winterfell, where she is reunited with Sansa and spars with Brienne, both of whom are unnerved by her skills with a sword. Bran unemotionally bids farewell to Meera, divulging that he is no longer the boy she accompanied north. Littlefinger presents Bran with the dagger that was nearly used to assassinate him. Jon brings Daenerys to the dragon glass mine, where the two find ancient cave paintings suggesting the First Men and the Children of the Forest joined forces against the undead. Missandei schools Jon and Davos on her devotion to Daenerys. Later, Daenerys learns that the Casterly Rock attack has gone awry and Highgarden has fallen; despite Tyrion's protests, she decides to take action. Theon arrives at Dragonstone, where he is confronted by Jon. Cersei promises the Iron Bank a full return on their investment, as a loot train from Highgarden is soon to arrive. Supervising the shipment of gold, Jaime and Bronn are caught in a surprise attack by the Dothraki, led by Daenerys, whose horde decimates the Lannister army. Though Drogon is wounded by a bolt from the scorpion weapon, Jaime attacks Daenerys head on; he and Bronn are felled by Drogon's fire breath and tumble into a lake, Jaime weighted down by his armor.
Jaime Lannister opens a wagon full of gold from the Tyrell vaults at Highgarden, the army is on the march back home. Bronn is there wondering why Jaime is upset. Bronn gets a cash reward but wants more. Jaime orders Bronn to help the Tarly's round up food from the local farmers. The Iron Bank rep thanks Cersei for the gold repayment, on its way. He suggests future deals and their support. Petyr Baelish sits with Bran and gives his me the Valeryian steel dagger that killed his mother, but doesn't know who owned it. Baelish promises support but is stopped by a cryptic comment. Meera Reed arrives to say she is leaving to be close to her family, she gets upset with his blasé thanks, he mutters he is no longer Brandon Stark. Arya arrives at the gates of Winterfell, the two guards don't believe she is a Stark, but she convinces them to let her in. She sits and views her home, then slips away from the guards. Sansa is told about Arya, smiles then goes to the crypts. The two sisters finally meet. Arya asks if Sansa killed Joffrey, and mentions her kill list. They meet Bran at the red tree, Bran is moody and knows about the list. Bran gives Arya the dagger. A Dragonstone Missandei and Daenerys wait for word from Greyworm. Jon Snow wants to show them a cave , they have found a large vein of dragonglass. Deeper in the cave Jon shows her ancient wall drawings, the Children of the Forest and First Men, and the Wights. Jon stresses they need to join together to fight the real enemy. Daenerys says she will fight for the North when he bends the knee. Outside the cave Tyrion has somber news about Casterly Rock. They need adjustments to their strategy, Daenerys is furious and wants to attack Kings Landing. She asks Jon's opinion, he hesitates but warns against attacking civilians. At Winterfell Brienne toys with Pod sparring with swords. Arya comes and wants to play. Arya displays superb fencing skills as Littlefinger and Sansa watch.

They chat with Dickon Tarly, it was his first battle. They hear a rumble and Jaime sounds the alarm for swords and shields, the foot soldiers scramble to form a line. Dothraki cavalry charge down the plains, and a dragon swoops in overhead. Dany rides and opens fire, burning a hole in the Lannister line, the Dothraki break through. Dany on her dragon provides aerial support burning the Lannister army. Jaime organizes a squad of archers to veer the dragon off, Bronn rides to get something. A Dothraki chops Bronn's horse's legs, he falls and loses his bag of silver. Getting to a wagon he arms the huge crossbow and searches the sky for the dragon. Tyrion watches with dismay from a hilltop as the Dothraki slaughter the Lannister army. As the dragon flies in low, Bronn fires but misses, he reloads. Coming back around his second shot hits the flying beast, Dany rides the injured animal to the ground. She dismounts and attempts to pull the bolt. Jaime sees a chance and charges with a lance. Just before the dragon turns to roast Jaime, Bronn knocks him aside and both men fall into the deep lake.
