The recent HBO leak that includes alleged outlines for Season 7 episodes 3 & 4 is now
publicly available.
The outline from episode 3 completely lines up with the aired episode, making people think that the
episode 4 outline is legit.
!!!SPOILERS BEHIND THE CUT!!!- Jaime leads a "loot train" from Highgarden to King's Landing. The Lannister army is shipping enough gold and food stores to pay off the Iron Bank and to sustain KL through the winter.
- Bronn asks to be given Highgarden as a reward, Jaime says he'll have a non-useless castle after the war. Bronn questions the Lannisters' ability to sustain peace after the war.
- The Iron Bank is happy with Cersei and bankrolls her contract with the Golden Company.
- Meera tells Bran she's leaving. Bran, blankly, just says "Thank you." Meera leaves the room (and the show) in tears.
- Littlefinger visits Bran and gives him the Valyrian steel dagger that was used in his assassination attempt. Bran spooks LF with details about LF's life (that he loved Catetyn) and quotes ("Chaos is a ladder").
- Bran has a vision montage of the assassination attempt, Tyrion being accused by Catelyn, Catelyn giving the dagger to LF who claims it as his own, and finally of himself being pushed out of the window by Jaime, remembering the whole scene for the first time.
- Jon and Dany meet in a dragon glass mine. No sex yet.
- After the cave Jon and Dany meet with Tyrion and Varys to learn about the Casterly Rock/Highgarden fiasco. Dany holds council, is unanimously talked out of riding a dragon to attack the Lannisters.
- Arya returns to Winterfell, has trouble with face control at the gate. Sansa is told of her arrival and goes to look for her. They have a lukewarm reunion in the crypts. Sansa tells her about Bran, they go to meet him.
- Bran is still by the tree. Arya asks about the dagger and tells him to run a Weirnet search for the culprit. Bran doesn't want to deal with it, nor does he want info/revenge – only the war matters. Arya doesn't get this decision / Bran.
- The three bb Starks go back to the courtyard for a homecoming, where LF looks at them unhappily.
- Theon arrives at Dragonstore, meets Jon. Jon tells him he won't kill him because he helped Sansa. Theon asks to see Dany, who's not there.
- Dany attacks Jaime's loot train with the Dothraki and Drogon. Destroys the tail of the caravan (though most wagons make it to KL). Drogon gets a shoulder wound from Qyburn's ballista, but is OK. Dany destroys much/most of the army and nearly toasts Jaime, who is saved by Bronn in the last second.
