HBO has added the final three episodes of the sixth season of Game of Thrones to its schedule, revealing not only some possible major spoilers, but also that the season 6 finale will be the longest single episode in the series’ history (so far anyway – winter is still coming). Suffice to say, previous episode spoilers and potentially serious spoilers about those to come follow. Read no further if you want to remain unsullied.

First up, the 8th episode set for June 12 is called “No One,” a title that almost certainly refers to the creed of the secret society of assassins, who shed all traces of their former lives, known as The Faceless Men. Arya Stark (Maise Williams) joined their ranks in season 5, but left the order in the May 29 episode “Blood of my Blood” after rejecting their amoral code and requirement that she become “no one.” This marked her for death and led to an attempt on her life at the end of last week’s “The Broken Man.”

In keeping with the brisk pace of season 6, it would appear Arya’s conflict with the Faceless Men may soon be wrapped up. The same seems to be true for the June 19 episode, “Battle of the Bastards.” The bastards in question would of course Ramsay Bolton (Iwan Rheon), a legitimized bastard now leading the clan who controls the former Stark family castle of Winterfell, and the recently-resurrected Jon Snow (Kit Harington), last seen trying to raise an army to liberate Winterfell and restore the Stark fortunes. Game of Thrones‘ producers have promised season 6 would see the biggest battle yet shown in series history, and this looks like the likely place for it.

Both episodes hint at huge changes to come for the show, but the biggest changes may come in the final episode, set to air June 26 and titled “The Winds of Winter.” That title is obviously a reference to the still-unpublished sixth book in George R.R. Martin’s novels on which Game of Thrones is based. While it doesn’t suggest any specific plot details, on HBO’s official Game of Thrones website it’s revealed the episode will be 69 minutes long, making it the series’ longest. Only the season 2 finale “Valar Morghulis” (64 minutes) and season four finale “The Children” (65 minutes) approach it.

We’ll leave you to speculate on what could be in store, but we will note three things: 1) Daenerys has recently made herself the leader of the Dothraki and is now bent on moving her army – and her three dragons – on Westeros to take the kingdom back; 2) the armies of The Night’s King (AKA the undead White Walkers) are themselves marching south to invade Westeros from north of the wall; and 3) both “Winds of Winter” and “Battle of the Bastards” are directed by Miguel Sapochnik, who also helmed season 5’s stand out entry “Hardhome,” the centerpiece of which was an enormous battle between outmatched humans and the forces of the Night’s King.

Sound off in comments, but try not to make any jokes about how much, or little, Jon Snow actually knows.

Entertainment Weekly first noted the length of the finale.
