'Game of Thrones' Season 5 Episode 6 to Feature Much-Awaited Sand Snake Attack [Spoilers]

Sunday's episode of "Game of Thrones" is entitled "Unbowed, Unbent, Unbroken," which is the motto of House Martell, and it can be safely assumed that the episode will focus heavily on Dorne.

A few spoiler photos from the episode have been released, and one shot shows Obara wielding a spear and Tyene holding her daggers. It looks like Oberyn Martell's daughters are gearing up for a fight, and they might soon get an opportunity as Jaime and Bronn will soon reach their destination, according to the official synopsis.

There are also pictures of Prince Doran's son Trystane and Myrcella Lannister, and speculation swirling around suggests that the young lovers will make plans to leave Dorne together.

While things took a turn for the worst for Jorah in the previous episode, what with him being affected by greyscale, latest pictures from "Unbowed, Unbent, Unbroken" shows him bonding with Tyrion.

It is not immediately known what will happen to Ser Jorah, but Iain Glen revealed in a recent interview that his character will be part of a major action scene later this season.

 "I've had bits and pieces of fighting through the course of the seasons," he told Entertainment Weekly. "I had the one-to-one with the Dothraki bloodrider, and then there was the sequence fighting to get into the city of Meereen. But this season will be the most substantial fighting I've had."

As for what else will happen in the sixth episode of the season, we'll see Arya start her training to become a Faceless Man.

In King's Landing we'll possibly see the return of Olenna Tyrell, Margaery's grandmother, as the Queen had earlier reached out to Olenna for help after her brother was arrested by the Faith Militant.

"Game of Thrones" airs Sundays on HBO. The official synopsis of the upcoming episode reads: "Arya trains. Jorah and Tyrion run into slavers. Trystane and Myrcella make plans. Jaime and Bronn reach their destination. The Sand Snakes attack."
