After tonight's episode of Game of Thrones titled The Broken Man, HBO released a new preview for next week's episode, No One, which airs Sunday, June 12 at 9 PM ET. There are only three episodes left this season, which promises to be quite epic. Be warned, if you haven't watched last night's episode, there will be plenty of SPOILERS below, so read on at your own risk.

Tonight's episode marked the return of a character thought to be dead, none other than Sandor "The Hound" Clegane (Rory McCann). We last saw The Hound in Season 4, where Brienne of Tarth (Gwendoline Christie) defeated him in battle. While we never saw him actually die, he was left for dead by both Brienne and Arya (Maisie Williams), who left Westeros behind and fled to the House of Black and White. As it turns out, The Hound was rescued by Ian McShane's unnamed character, but at the end of this episode, he was slaughtered along with the rest of his followers. We get a brief glimpse of The Hound in this preview, where he's seen swinging an axe against an unknown enemy.

While we don't know for sure, there have been rumors that this season could featured the long-rumored "Cleganebowl," where The Hound will square off against his brother, Gregor "The Mountain" Clegane (Hafthor Júlíus Bjornsson). Last season, The Mountain was brought back from the dead by Qyburn (Anton Lesser) where he was put in charge of guarding Cersei Lannister (Lena Headey). We'll have to wait and see if this showdown will actually happen.

We also see Cersei and The Mountain squaring off with Lancel Lannister (Eugene Simon), who tells the Queen Mother to have her man stand aside or there will be violence. There is also another important scene which teases Brienne may have to do battle with her former friend, Jamie Lannister (Nikolaj Coster-Waldau). In last night's episode, we saw Sansa (Sophie Turner) writing a letter to an unknown person, which turns out to be Blackfish (Clive Russell). Brienne is seen delivering Sansa's decree to Blackfish, telling Jaime that if Blackfish refuses to surrender, she'll be forced to fight him.

We also get a glimpse of Tyrion Lannister (Peter Dinklage) while we also see The Waif (Faye Marsay). One of the most shocking moments of last night's episode is when Arya booked passage to return to Westeros, only to be stabbed several times by The Waif. She was last seen stumbling through the streets of Braavos, bleeding from her wounds in the gut. We'll have to wait and see if she finds any help in No One, which airs next Sunday. In the meantime, take a look at this preview below, along with an inside look at last night's 7th episode courtesy of Youtube.
