Season 7The Queen's Justice
Jon arrives at Dragonstone. Daenerys demands his fealty; he refuses and seeks her help fighting the Army of the Dead. On Tyrion's advice, Daenerys allows Jon to mine the island's dragonglass. Melisandre avoids Jon and departs for Volantis. Bran, with Meera, arrives at Winterfell and reveals to Sansa his new identity as the Three-Eyed Raven. In King's Landing, Euron presents Ellaria and Tyene as gifts to Cersei, who promises him marriage after the war is won and makes him commander of her navy; he snubs Jaime. Cersei administers the same poison to Tyene that killed Myrcella; Ellaria will watch her daughter die, imprisoned with the body. In Oldtown, a healed Jorah leaves to find Daenerys. Ebrose praises Samwell's skill in saving Jorah but makes him copy old texts for his disobedience. Grey Worm and the Unsullied attack Casterly Rock but find that Jaime has led the bulk of the Lannister forces to attack Highgarden, while Euron's fleet ambushes and destroys the Unsullied's ships. The Lannister forces quickly overwhelm Olenna Tyrell's army. Jaime offers Olenna a quick and painless death by poison. After drinking it, she admits to poisoning Joffrey.
