This Sunday's episode of HBO's fantasy drama "Game of Thrones" is titled "Blood of My Blood," a Dothraki saying, and it looks like Margaery will be forced to do the walk of shame in the coming episode. The official synopsis for the episode does not give any clues to what's in store for Margaery, but photos from the episode show her preparing for the walk of atonement similar to what Cersei did in the previous season.

It remains to be seen if Margaery will be paraded naked on the streets of King's Landing, but actress Natalie Dormer teased at such an ordeal happening to her onscreen character as well. She also said that sharing a similar experience, and the existence of a common foe in the High Sparrow could bring Margaery and Cersei together.

The preview for the episode also hints at fans learning more about the Tower of Joy, and this has sparked speculation that the show will finally reveal yet another spoiler from George R. R. Martin's "A Song of Ice and Fire" series. The identity of Jon Snow's real parents has been the source of a lot of speculation, with a popular theory stating that it's none other than Ned Stark's sister Lyanna and Rhaegar Targaryen. A Reddit thread, which reportedly contains spoilers from the rest of Season 6, also hints at Lyanna being Jon Snow's mother.

"Lyanna whispers something to Ned before she dies. We then see a baby, and the very next scene we see Jon," Reddit user Truede wrote regarding the big reveal.

The official synopsis for "Blood of My Blood" 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)."

"Game of Thrones" Season 6 episode 6 "Blood of My Blood" will air this Sunday, at 9 p.m. EDT on HBO. The episode can also be watched through HBO Go, HBO Now and Hotstar.
