With the release of two new Game of Thrones episode titles and descriptions, HBO has fueled the flames of viewer speculation anew. Dubbed "Blood of My Blood," the synopsis for the sixth episode of the season reads, "An old foe comes back into the picture. Gilly (Hannah Murray) meets Sam’s (John Bradley) family. Arya (Maisie Williams) faces a difficult choice. Jaime (Nikolaj Coster-Waldau) faces off against the High Sparrow (Jonathan Pryce)."
But while these details no doubt contain a lot of hidden information, some fans believe the title holds the biggest clue of what's to come. Based on an interview in which Kit Harington told Entertainment Weekly that, "There’s one episode this season, which is Jon’s story, that’s the most epic episode we’ve done," one Reddit user has theorized that "Blood of My Blood" will finally reveal who Jon Snow's real parents are.
"I'm calling it right now, episode 6 will be all about Jon Snow and it will be the episode where we'll confirm R+L=J [a popular fan theory positing that Jon is not Ned Stark's bastard, but rather the son of Lyanna Stark and Rhaegar Targaryen]," the Redditor wrote. "'Blood of my Blood' certainly refers to Ned being Lyanna's brother. Jon still shares Ned's blood through her. If I'm right, we'll probably see a lot of Targaryen backstory, probably through Bran (who's getting more and more adventurous in his visions, if we believe the preview for episode 5)."
However, the user acknowledges the name could also be a nod to Daenerys's storyline — referencing the translation of the Dothraki phrase, "Qoy Qoyi" — as well as several other plot points.
And if you're curious about episode seven, here's the description for, "The Broken Man": "The High Sparrow eyes another target. Jaime confronts a hero. Arya makes a plan. The North is reminded."
“The Door,” the fifth episode of Game of Thrones’ sixth season, airs Sunday at 9 p.m. EST on HBO.
