HBO's "Game of Thrones" is four episodes into what is shaping up to be a phenomenal season of television. Last week's episode, "Book of the Stranger," gave fans touching reunions and a big WOW moment from Daenerys. But what will these momentous shifts lead to going forward?

HBO has released titles and mysterious descriptions for two additional episodes. This time around, it's the sixth and seventh episodes of the season, which are sure to pique your interest.

-May 29: "Blood of My Blood": 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). Written by Bryan Cogman; directed by Jack Bender.

-June 5: "The Broken Man": The High Sparrow eyes another target. Jaime confronts a hero. Arya makes a plan. The North is reminded. Written by Bryan Cogman; directed by Mark Mylod.

"Blood of My Blood" could be a direct reference to the Dothraki, meaning that Daenerys may be a big focus of the sixth episode. As we saw in "Book of the Stranger," Dany killed all of the Khals and has now added 100,000 Dothraki to her cause. That should help balance the scales against the Yunkai and Astapor forces.

As for Arya, my best guess is that the difficult choice she will face will either be a tricky mission (we've been waiting for her Mercy chapter from "The Winds of Winter") or the final test of her loyalty to The House of Black and White. Perhaps the Faceless men require her to truly become no one as a part of a graduation ceremony, yet Arya is unwilling to abandon her true identity.

"The Broken Man" seems to promise something of a Stark comeback. How else would you describe "The North is reminded?" Viewers would love to see Jon Snow, Sansa Stark, Tormund and company start to rally troops in the North to take on the Bolton and reclaim Winterfell. Everyone would also love to see Ramsey suffer a grisly death. Fingers crossed.

"Game of thrones" airs Sundays at 9 p.m  ET on HBO.
