Fans of HBO’s hit series “Game of Thrones” can’t stop buzzing about the impending faceoff between Jon Snow and Ramsay Bolton, but could something bigger be on the horizon?

On Reddit user suggests a betrayal may be brewing — and it’s a big one. Varys (Conleth Hill) fled Meereen in a hurry during Season 6, episode 8 on a secret mission, providing no details about his plans. According to Redditor Ariskov, Varys’ mission may revolve around his loyalty to the realm. In a thread on the site, the user reminds “Game of Thrones” fans of a scene from Season 2 in which Varys denounces Stannis Baratheon (Stephen Dillane), claiming his links to the Lord of Light make him unfit for the Iron Throne. Ariskov suggests that, given the recent visit from Kinvara (Ania Bukstein), a third red priestess, Varys may be questioning Daenerys’ (Emilia Clarke) right to rule the seven kingdoms. The Reddit thread raises questions about Varys potentially sabotaging the mother of dragons.

“Varys repeatedly says that he serve[s] the realm,” Ariskov wrote on Reddit. “He ignores all kinds of right[s] to rule, names, laws and only keeps the peace [and] interest of the realm as [his] sole criterion. It doesn’t sound right that he would help a vengeful conqueror. Let alone a vengeful conqueror who is the [prophesied] savior of the religion he hates and fears.”

The Reddit user points out that Varys has made a name for himself on “Game of Thrones” — and in both Westeros and Essos, as “A F---ING SPY MASTER” and “GRANDMASTER OF SECRETS AND WHISPERS AND BIRDS.” Given this fact, he questions how it is possible that a man with an expansive network of spies could not have seen the attack on Daenerys’ fleet coming — could it be because he orchestrated the attack himself? Ariskov wrote that, while the attack was pinned on the slavers, it “does not make much sense.” The Redditor points out that if anyone would want the former Khaleesi and her crew to leave Meereen, it’s the slavers. Burning her ships would be counterproductive to that point.

“Destroying [her] means of transportation and making sure that she stays at Slaver’s Bay longer doesn’t make sense. It makes sense for someone who doesn’t want Daenerys to leave for conquest soon,” Ariskov said.

While these suggestions are merely speculation, a few things are known for certain about the remaining episodes in Season 6. Namely, the fact that Jon Snow and Ramsay Bolton (Iwan Rheon) will finally come face-to-face to battle over Winterfell. A preview for the episode shows House Stark preparing for the battle to come. In one particular scene, Jon Snow tells Melisandre (Carice van Houten), who came to him after Stannis’ death, not to bring him back should this battle cost him his life again. With only a small army composed of Wildlings, a couple men from House Mormont and a few small groups of men from lesser-known houses, Sansa Stark (Sophie Turner) takes matters into her own hands. As you may recall from Season 6, episode 8, the eldest Stark daughter sent a raven to someone, though it’s unclear who. One theory suggests she may have reached out to Petyr “Littlefinger” Baelish (Aidan Gillen) about sending the men of the Vale to fight alongside them.

Although the title of Season 6, episode 8, “Battle of the Bastards,” pretty clearly outlines the episode’s plot, the finale remains far more vague. On June 9, HBO revealed that the final episode will be titled, “Winds of Winter,” a nod to George R.R. Martin’s forthcoming novel in the “A Song of Ice and Fire” series. The episode will be nine minutes longer than normal episodes. No synopsis was revealed, forcing fans to guess what the contents of the show will be. It is possible that the finale will focus on wrapping up Cersei Lannister’s (Lena Headey) portion of the story — provided she lives, of course. As was revealed in episode 8, under King Tommen Lannister’s (Dean-Charles Chapman) most recent decree, the queen is unable to choose trial by combat in her impending trial before the members of the faith. Should the finale center on her, fans should expect no shortage of violence and bloodshed.
