Shortly after last night's Game of Thrones Season 7 Episode 2, HBO aired a brief preview for Season 7, Episode 3, The Queen's Justice, airing Sunday, July 30 at 9 PM ET. We also have a new photo from next week's episode featuring Tyrion Lannister (Peter Dinklage), along with four photos from last night's episode featuring Jon Snow (Kit Harington), Arya Stark (Maisie Williams), Samwell Tarly (John Bradley) and a group of youngsters training on a bow and arrow in Winterfell. If you haven't seen last night's episode yet, there will be SPOILERS below, so read on at your own risk.

The trailer, which debuted on HBO YouTube, opens with Daenerys Targaryen (Emilia Clarke) settling into her new temporary home at Dragonstone, with her three massive dragons hovering around overhead, with Dany telling an unseen character that she was "born to rule the Seven Kingdoms." We then see Euron Greyjoy returning to King's Landing, getting a hero's welcome after helping Queen Cersei Lannister (Lena Headey) achieve the first victory in what will be known as the Great War. While we don't exactly see it, Euron has brought Cersei a "gift," which he promised her in the Season premiere.

In desperate need of new allies, Cersei Lannister sent for Euron Greyjoy (Pilou Asbaek), the new king of the Iron Islands, who proposed that he and Cersei get married. While she rejected his proposal, he vowed to return to King's Landing with a "gift" for Cersei, although he never mentioned exactly what that gift was. We found out in last night's episode Stormborn that the gift in question was none other than Ellaria Sand (Indira Varma). In last night's episode, Daenerys laid out her entire battle plan, telling both Olenna Tyrell (Diana Rigg) and Ellaria Sand to bring the Tyrell and Dorne armies back to her, so they can take King's Landing. As for the army of unsullied and Dothraki warriors, they will have a different purpose, to take Casterly Rock, the seat of the Lannister's power. On the way back to Dorne, though, they ran into a little problem: Euron Greyjoy.

Euron and his massive fleet attacked the fleet possessed by his niece Yara (Gemma Whelan) and nephew Theon (Alfie Allen), killing almost everyone on board, including two of Ellaria's daughters known as the Sand Snakes, Nymeria (Jessica Henwick) and Obara (Keisha Castle-Hughes), although Ellaria was taken captive. It seems Ellaria, who orchestrated the poisoning death of Cersei's daughter Myrcella (Nell Tiger Free) in the Season 5 finale, will now answer for her heinous crime in front of Cersei herself, which is likely what the episode's title The Queen's Justice alludes to. How Cersei will deal with Ellaria remains to be seen, but it certainly won't be pretty.

The trailer also features a number of random shots of unsullied warriors heading into battle, which means we'll likely see the unsullied invasion of Casterly Rock in this episode. The trailer ends with the moment many fans have been waiting for, the first meeting of Jon Snow. This meeting was teased in set photos that surfaced last year, although it revealed this meeting took place on the Dragonstone beaches. This meeting will certainly be a pivotal point in the season, since Jon Snow wants the dragon glass buried underneath Dragonstone to fight the White Walkers, while Dany seeks more allies to her cause.
