Be careful, spoilers for the fourth episode of "Game of Thrones" season 7 will follow! The next episode of the HBO's TV series, titled "The Spoils Of War," is going to be an action-packed one. In the "The Spoils of War" official trailer, we can see Daenerys riding Drogon into battle, Daenerys and Jon descending into a cave, Arya finally reaching Winterfell, and Brienne of Tarth fighting against someone. Many fans are wondering who Brienne is fighting in that scene, so let's see what is going to happen to her.

The Starks reunion is approaching

As you can see from the trailer at the bottom of the article, Arya will arrive at Winterfell in the next episode.

There she will find her brother Bran, her sister Sansa, and Brienne of Tarth. The last time Arya and Brienne saw each other was in season 4, when Brienne stumbled upon the young Stark and Sandor Clegane and, willing to honor her vow to Catelyn, urged Arya to join her. As you may remember, Arya refused Brienne's proposal. The Virgin of Tarth fought The Hound to take Arya under her custody, but after the duel, she realized Arya had snuck away.

Mirror mirror on the wall, who is the best fighter of them all?

In "Game of Thrones" season 7 episode 2, we saw Brienne sparring with Pod. It's likely that we will see another Brienne-Pod sparring scene in episode 4, but this time someone will show up to take Podrick's place and spar with Brienne.

The person who is going to fight Brienne is Arya Stark.

Yes! We're going to see a friendly fight between Brienne and Arya! In the next episode, according to two leakers, Brienne will decide to take it easy on the girl, but soon she will realize that Arya's ability with the sword is impressive. In the end, Brienne will admit that Arya could definitely kill her.

Sansa and Littlefinger

Sansa will witness the fight. According to a leaker, she will be shocked by Arya's demonstration of strength. Littlefinger, as a smart guy, will immediately recognize Arya as a threat. On the other hand, Brienne is going to be very proud to see both the Starks sisters in Winterfell: it means she somehow has kept her vow to Catelyn.

Are these spoilers legit?

This article is based on what the leaker "Awayforthelads" wrote on Reddit a long time ago and on "Frikidoctor"'s videos. Since many of their spoilers have already been confirmed by the first three episodes of "Game of Thrones" season 7, is very likely that these spoilers are legit.
