This week's Game of Thrones episode marks the halfway point of Season 6, which has already seen a fan-favorite come back from the dead, many others killed and a brutal fire that is still being talked about. With just two days left until the fifth episode, The Door arrives, the network has released the plot synopses for the next two episodes after that, Blood of My Blood, airing on Sunday, May 29 at 9 PM ET and The Broken Man, airing June 5. If you aren't caught up on this season quite yet, there will be SPOILERS addressed below, so read on at your own risk.

The Blood of My Blood synopsis, courtesy of HBO, teases that an "old foe comes back into the picture," although we aren't quite sure who is being referred to. Over the past five seasons, there have been a number of villainous characters who have come and gone, and it seems to be a recurring theme this season that many characters are returning after lengthy hiatuses. One of the villains it could be is Walder Frey (David Bradley), who orchestrated the infamous Red Wedding massacre in Season 3. David Bradley himself confirmed in August that his character will be back, but he wouldn't say if his return will happen in Season 6. There has also been speculation that Sandor "The Hound" Clegane (Rory McCann) could return as well, potentially setting up the showdown many have been waiting for between the Clegane brothers, The Hound and The Mountain (Hafþór Júlíus Björnsson), which fans have dubbed the "Cleganebowl."

The plot rundown also reveals that Gilly (Hannah Murray) will meet Sam's (John Bradley) family. We first saw Sam and Gilly in the third episode of this season, Oathbreaker, where Sam informed Gilly that it may not be wise for her to stay in Oldtown with the baby, revealing he plans on taking her to his parents. We reported back in September that James Faulkner has been cast to play Sam's father, Randyll Tarly, with Samantha Spiro, Rebecca Benson and Freddie Stroma coming aboard to play Sam's mother, sister and younger brother, respectively. There had been rumors that Sam may visit his home, House Tarly of Horn Hill, on the way to Oldtown, which has now been confirmed. This synopsis also reveals that Arya (Maisie Williams) will face a difficult choice, while Jaime Lannister (Nikolaj Coster-Waldau) squares off against the High Sparrow (Jonathan Pryce).

The seventh episode of this season, The Broken Man, will follow The High Sparrow as he "eyes another target," while Jaime confronts a hero. The synopsis also reveals that Arya will make a plan, and that "The North is reminded." While we don't know who the High Sparrow is targeting, it's clear that he survives his confrontation with Jaime Lannister from the previous episode, and we don't know for sure who the "hero" Jaime will confront. "The North is reminded" line is a direct callback to the George R.R. Martin books, particularly a scene where Lord Manderley, who is loyal to the Stark clan, reveals that the North remembers everything the Bolton clan has done to the Stark's, from the Red Wedding to their family taking over Winterfell.

We know that Jon Snow (Kit Harington) and Sansa Stark (Sophie Turner) are making plans to take back the North from the Bolton's, and it seems possible that they could be getting some help from other clans in the North. There is a long-held fan theory that the rest of these Northern houses unite to run the Bolton's out of Winterfell, before naming Jon Snow the new King of the North. Naturally, that hasn't been confirmed, but now that Jon is leaving the Night's Watch, it certainly could be possible. Stay tuned for more on Game of Thrones as this thrilling season continues.
