30 best Game of Thrones theories for season 8
- After nearly two years, here are the 30 best theories about the final season
- The first episode of Game of Thrones Season 8 will be shown in the US later today
- Each episode of the final season is rumoured to cost US$15-million a pop
- The last episode of Season 7 aired almost two years ago
We've had nearly 20 months since its Season Seven finale to contemplate how Game of Thrones will end. That's enough time to, without sleep, watch the entire series about 212 times through. And, judging by the depth of analysis that fans put into this show, it's easy to imagine that some people have watched Game of Thrones that much.
As such, Game of Thrones has never been far from mind over the last year and seven months. Fans have been active on Reddit and elsewhere, coming up with new clues and details through re-watches that could come back in Game of Thrones Season Eight.
Leading up to Game of Thrones Season Eight, we've spent nearly two years following the deep dives, rumors, and spoilers to compile and ultimate list of the 30 most important fan theories for the final season.
The Night King will turn the dead Starks beneath Winterfell into wights
What if the White Walkers somehow found a way to reanimate the dead Starks buried in the Winterfell crypts? Before you say that's too fucked up—even for Game of Thrones, consider the symbolism we've seen in the promotional material for this season so far. There was that teaser of Jon, Arya, and Sansa walking through the Winterfell crypts looking at all the faces of the dead buried there. Then, in the first trailer, we see Arya sprinting in fear from something beneath Winterfell.
Nothing would freak Arya out more than seeing the reanimated corpses of her family who have died in this war. Old Nan, Maester Luwin, and—if their bodies were brought back to Winterfell after their deaths—Robb, Ned, Catelyn, and Rickon could be exactly what's frightening her.
More specifically, Catelyn returning as a wight would be some good fan service for another reason: It would be a nod to the books' Lady Stoneheart (an undead version of Catelyn who has not yet appeared in the show).
Consider this also from a strategic point of view for the Night King. He's laying siege to Winterfell, and what better way to attack from within the gates than creating a bunch of soldiers to take the living by surprise? That, some have speculated, is why we see Arya running like this—up from the crypts to warn everyone else.
Jon Snow will find evidence to prove his Targaryen lineage
One important hurdle that Jon and Sam and Bran will have to overcome is trying to prove that Jon is actually a Targaryen. Is anyone—especially Cersei Lannister—going to take the word of Jon's weirdo little brother who says he can see into the past? Absolutely not! The only other proof they have is an old record from High Septon Maynard that simply states that Rhaegar had annulled his marriage to Elia Martel and married Lyanna Stark in Dorne.
So what could they possibly do to prove his identity with physical evidence? As we know from Martin's books, Rhaegar Targaryen was a gentle romantic known for composing music and playing the harp. Since the early days of Game of Thrones, there's been a rumor that this famed harp of Rhaegar Targaryen's is down in the Winterfell crypts with Lyanna Stark's body. But, there might be more. In the first episode of Game of Thrones, Robert Baratheon leaves a feather on Lyanna Stark's grave. This feather has been called back to at multiple times throughout the series, most recently in the latest Thrones teaser showing the destruction of Winterfell. What could be in this grave that is so important?
Is it possible that the Song of Ice and Fire from which George R.R. Martin's epic book series gets its name is an actual song written by Rhaegar Targaryen to commemorate the birth of his and Lyanna Stark's son Aegon Targaryen? Could it be possible that Rhaegar wrote this song and it is placed with Lyanna stark with his harp in her grave as proof of Jon Snow's true lineage? —Matt Miller
Dany will turn into the ultimate villain, the Mad Queen
Madness runs in her blood. Dany’s father was the Mad King Aerys II Targaryen, against whom the Baratheons revolted to set up the era of Westeros we’re familiar with. He burned anyone who was disloyal to him, and as Dany proved last season when she torched two Tarly lords alive, she hasn’t shied away from following in his ignoble footsteps. She asserts that she cannot be held accountable for her father’s actions, but she demands the Westeros ruling families recognize his power in her.
For seven seasons, Dany has positioned herself as the unimpeachable leader of the freed people. But she remains blind to her own weaknesses, even after Tyrion warned her she is vulnerable atop her dragons, and Jon warned her using her dragons to wage war would make her just like every other tyrant to fight for the throne. And as one Redditor points out, Dany would make for an interesting, sympathetic, and extremely dangerous villain—the kind Game of Thrones might favor in the end over obvious baddies like the Night King and Cersei.
In Season Seven, Tyrion told Jon, “She protects people from monsters.” But she could be a few horrid judgement calls away from becoming the monster herself. — Sarah Rense
Dany will become the Night Queen
There’s quite a bit of evidence that Dany could become the new Night Queen, a figure in George R.R. Martin's A Song of Ice and Fire who appears to be a female White Walker. As the Game of Thrones Wiki describes:
According to legend, a Lord Commander of the Night's Watch found in the Haunted Forest a cold woman with bright blue eyes, seemingly a female White Walker. He took her to the other side of the Wall and declared himself "Night's King". For thirteen years the two ruled over the brothers of the Night's Watch, performing human sacrifices. The Free Folk rallied under the banner of a King-Beyond-the-Wall, Joramun, and marched against the Nightfort, which the Night's King had taken as his seat, defeating him and his queen with the aid of House Stark.
Our own Daenerys Targaryen physically resembles the Night Queen of legend, with her pale skin and white hair, and in one particular scene that some Redditors read as foreshadowing, her eyes blazed blue as she walked out of the House of the Undying in a vision. In this Season Two vision, Dany was distracted from the Iron Throne by the sounds of dragons crying, prompting her to wander North of the Wall, where she sees Drogo and her unborn baby. It was a tempting taste of the afterlife, and maybe reason enough for Dany to join her family in death. Another Redditor theory predicts Dany’s remaining dragons will die in the North, and the Night King will persuade her to become his Night Queen so she can be reunited with her children. — Sarah Rense
Jon will sacrifice himself for the Princess That Was Promised
As we've learned in Game of Thrones prophecies are often misinterpreted. And in Season Seven, Missandei points out that the ancient reading of the Azor Ahai prophecy could actually be wrong. It turns out the word for prince has no gender—meaning it could be a princess who was promised rather than a prince. That would mean instead of Jon Snow being the Lord of Light, it could be Daenerys.
If that's the case, we'd actually have to flip the reading on one of the most popular Daenerys theories that she will sacrifice herself for the Prince That Was Promised. In this scenario, Jon would in fact sacrifice himself so that Dany could create Lightbringer to slay the Night King. And, honestly, considering Jon has already died once, it would make sense that he was brought back to serve this purpose only to die again. —Matt Miller
Jon and Dany will betray each other
Okay, so we know that nothing good can come from noted aunt and nephew Daenerys and Jon sleeping with each other. Besides the fact that it's just some light incest, politically this isn't likely to work out well for everyone. As we've already seen from early trailers, this union of dragon and wolf is already causing a divide among the ranks. And if things continue to get worse, it could lead to an ultimate betrayal. In a vision in the book version of the House of the Undying, Dany is given this prophecy: "three fires must you light... one for life and one for death and one to love... three mounts must you ride... one to bed and one to dread and one to love... three treasons will you know... once for blood and once for gold and once for love..."
As we await this third betrayal, it seems very likely that it could be Jon doing the betrayal for love or visa versa. In the show, back in Season Two, this scene shows Dany in an empty King's Landing approaching the Iron Throne. But, before she can get there, she is interrupted by the cries of her dragons. This also has sparked theories that she will abandon her fight for the Iron Throne to be with her dragons again, possibly becoming the Night Queen in the process. —Matt Miller
Jon Snow will finally ride a dragon
Now that we finally know that Jon Snow is a Targaryen, then that means he can theoretically ride a dragon. Fans have been waiting decades for this confirmation, and now that we have it, the next step is for our hero to climb on the back of one of the dragons.
In one of the trailers, we see Jon and Dany walking up to her dragons. As fans have already pointed out, this must be the two remaining Targaryens approaching their dragons for a ride into battle.
Now, since Daenerys has always favored Drogon, named after her late husband Khal Drogo, she'll likely continue to ride him into battle. That leaves Rhaegal for Jon to ride, which is fitting considering he is named after Jon's real father, Rhaegar Targaryen.
Sansa and Gendry end up together
This theory explains blacksmith Gendry's surprising reappearance in Season Seven. As one fan points out on Reddit, Ned Stark predicted in Season One that his daughter would end up with "someone strong, and wise, and brave"—all characteristics Gendry possesses, of course. Gendry is of noble birth, as the last living Baratheon. We know he gets along well with Sansa's sister, Arya. And, because he is a blacksmith with very valuable knowledge, he could play a heroic role in the final season as the White Walkers approach. It's a rare happy theory that provides a beautiful parallel between the strong Stark and Baratheon connection. —Kate Storey
Sansa is pregnant with Ramsay Bolton's baby
Ugh, let's hope this theory isn't true. But it comes from this line Sansa says to Littlefinger about her wedding night to Ramsay: "I can still feel it. I don't mean 'in my tender heart it still pains me so' — I can still feel what he did in my body standing here right now."
This theory hinges on how much time has passed between Seasons 7 and 8. Ramsay died in Season 6, so Sansa's pregnancy would have shown in Season 7 unless the timeline has been more compressed than we realized. —Kate Storey
Our sweet boy Sam is actually the Prince That Was Promised
In George R.R. Martin's A Song of Ice and Fire, Azor Ahai is a legendary figure "who fought against [the darkness] with a red sword" and "arose to give courage to the race of men and lead the virtuous into battle with his blazing sword Lightbringer." According to prophecy, "When the red star bleeds and the darkness gathers, Azor Ahai shall be born again amidst smoke and salt to wake dragons out of stone." As one Game of Thrones theory outlines, Sam could very well be a secret Targaryen—the child of Rhaegar and Elia Martell (his first wife whose marriage he had annulled). This child was smuggled away by Varys and sent to one of the most faithful Targaryen families the Tarlys.
Samwell had inherited his mother's Dornish looks and most of her character: kind and clever, with a gentle heart and a sweet wit, though with a delicate health; exactly like Ser Barristan Selmy had described Elia. From his father, Sam had inherited Rhaegar's love for books and songs instead of his ability for battle. Lord Randyll, being the Tarly that he is, tried his best to raise the young Prince as a fighter. But even after giving it his all, poor Sam could not do it. His training was proving a failure. And to cope with the stress and the pain, Sam hid behind food...
Jaime Is the Prince That Was Promised
One of the beautiful things about the story that George R.R. Martin built is that, with only six episodes left, anyone could be the story's foretold hero: The Prince (Or Princess) That Was Promised. This goes for Jaime Lannister as well. Who's to say this legendary hero can't be reborn from a Kingslayer into a villain who transitioned to the good guy's team? I'll be honest in saying the case for Jaime isn't as strong as some other characters, but there is some evidence to back it up.
Azor Ahai is a legendary figure "who fought against [the darkness] with a red sword" and "arose to give courage to the race of men and lead the virtuous into battle with his blazing sword Lightbringer." According to prophecy, "When the red star bleeds and the darkness gathers, Azor Ahai shall be born again amidst smoke and salt to wake dragons out of stone." Melisandre is a Red Priestess in the religion of R'hllor, who has been searching for The Prince That Was Promised—or, a prophesied savior in the religion of the Lord of Light, who is often considered to be a reincarnation of the legendary hero.
As one Redditor has pointed out, the High Valyrian words for "Lord" and "Light" are "aeksio" and "onos." The words for "gold" and "hand" are "aeksion" and "ondos." If that sounds familiar, that's because Jaime happens to have one hand made of gold, and he's jokingly referred to himself as Goldenhand.
If that's not enough, other fans have pointed to Jaime's character path as a whole, which mirrors that of The Prince That Was Promised. Consider what happened to him in Season Seven: Jaime was literally consumed by fire when attacked by Dany's dragons and has risen from that battle reborn—in the sense that he literally changed sides in this war—to go join the living in their fight against the undead.
Jaime will kill the Night King
He is the Kingslayer, after all. Wouldn't it be clever if Jaime's dishonorable title was actually a hint to the ultimate endgame? Jaime actually has a few options at his disposal to do the deed. Remember, he has in his possession Widow's Wail, a Valyrian steel sword that he took from Joffrey after his death. Jaime also has the knowledge of the giant scorpion arrow launcher that Cersei had built to attempt to kill dragons. Put a Valyrian steel arrow in this bad boy and you have yourself a hell of a Ice Dragon/Night King slaying toy.
But let's also consider the beauty of Jaime's arc in this situation. He killed one fire king and was dishonored and he killed one ice king for redemption. Beautiful.
Melisandre will return with an army to save the day
When we last saw the Red Priestess Melisandre in Season Seven, she shot a not-so-subtle threat at Varys before announcing that she was going to sail across the Narrow Sea to Volantis, which is one of the Free Cities of Essos. But that's not the last we'll see of her—she told us as much. "I will return, dear Spider, one last time," she said to Varys. "I have to die in this strange country, just like you."
As we know, Melisandre is a Red Priestess in the religion of R'hllor, the Lord of Light, which has played a supporting role throughout the series, but has never been fully explained. Volantis is home to one of the largest Red Temples in the religion of R'hllor, and also happens to be where Kinvara—the Red Priestess we met in Season Six—is from. If you'll recall, Kinvara met with Tyrion and told him she believed that Daenerys is the Princess That Was Promised. She also agreed to convince her people to follow Daenerys, which is great news, because she's kind of a big deal where she's from (her full title is High Priestess of the Red Temple of Volantis, the Flame of Truth, the Light of Wisdom, and First Servant of the Lord of Light). Considering they're both going to converge in Volantis and they're both part of the same crew and they both believe in Daenerys' cause, it's safe to assume Melisandre and Kinvara will team up. As fans have pointed out, Volantis is guarded by a massive army called the Fiery Hand, which Tyrion sees in A Dance With Dragons. Hmm, an army that follows a fire god sounds pretty useful in a battle against ice undead monsters who are vulnerable to fire...
Ned Stark is alive and will return
OK, I know this sounds crazy, but there's a lot of evidence out there that this could possibly happen in their early report from the set of Season Eight, EW wrote that they saw a number of characters that they didn't expect to see again. Who would be more unexpected than Ned Stark? Plus, people die all the time on this show and come back. Jon Snow, The Hound, Beric Dondarrion, The Mountain, and, in the books, Catelyn Stark—they all are resurrected in some form or another. Yes, everyone watched as Ned's head was very clearly severed from his body and placed on a spike on the ramparts of King's Landing. But, what if that wasn't actually Ned Stark who was beheaded in front of his entire family, the fancy royalty, and a bunch of angry, dirty commoners?
According to the theory, Jaqen H'ghar of the Faceless Men and Ned Stark were being held prisoner in the Red Keep at the same time. If you recall, back in Season One, Arya first meets Jaqen when he's being transported out of the Red Keep as a prisoner. Now, it seems strange that a Faceless Man would be so easily imprisoned. So it's logical to believe that he was captured on purpose. That purpose was for Varys to pay Jaqen to replace Ned Stark at his execution with an imposter. Ned has had to stay in hiding and travel away from Westeros where he won't be discovered. He's also working for Varys to help pay off the debt owed to the Faceless Men.
Tyrion is actually a Targaryen, too
Now that we know Jon Snow is a Targaryen, the next surprise sibling will be none other than Tyrion. This comes from the popular A + J = T theory, which means Aerys plus Joanna equals Tyrion. The books detail the Mad King Aerys's obsession with Tywin Lannister's wife, Joanna. According to the theory, Aerys impregnated Joanna, who died when giving birth to Tywin (similarly, so did two other Targaryan siblings: Jon and Daenerys). It would also explain Tywin's final words to Tyrion—"you're no son of mine"—along with his general disdain for his youngest son. And remember how chill Tyrion was with those little dragons?
Tyrion made a deal with Cersei and will betray Daenerys
While this would make the previous theory pretty complicated, many fans believe that an important conversation went down between Tyrion and Cersei that wasn't shown in the Season Seven finale. Remember when Tyrion was convincing Cersei to work with Jon/Dany and noticed that she was pregnant, then the next scene cut to them back in the Dragonpit? During that gap, Tyrion might have made a deal with Cersei to ensure that her unborn child would be the king/queen to succeed Daenerys, who Tyrion believes is unable to have children. That would explain his concern while listening to Jon and Dany have sex on their steamy romance cruise in the finale. If she has a baby, that would really mess up his plans.
Tyrion is the Prince that Was Promised
We’re still waiting to find out just who Azor Ahai/The Prince That Was Promised will be and one theory holds that Tyrion’s the guy. The original Azor Ahai was a great warrior who defeated the White Walkers generations ago, bringing the Long Night to an end. Many of the societies in Martin’s books feature tales such a savior, and some fans posit that Azor Ahai, the Prince That Was Promised, and The Last Hero are all the same White Walker-fighting figure, prophesied to return to battle his blue-eyed nemeses once more.
According to the prophesies, Azor Ahai "shall be born again amidst smoke and salt to wake dragons out of stone,” and they’ll wield Lightbringer, the "Red Sword of Heroes.” Melisandre used to think Stannis was the promised prince, but in Season Seven she declared that both Jon Snow and Daenerys could play a role in the prophecy, which makes sense as Daenerys woke her dragons out of their eggs and Jon Snow’s Valerian Steel sword, Longclaw, is a proven White Walker-killer.
But there might be room for Tyrion in this thing—he was metaphorically reborn amidst the smoke of wildfire and ocean sea salt at the Battle of the Blackwater, and he definitely proved himself to be a deft hand with Dany’s dragons when he successfully freed Viserion and Rhaegal. His case for being the PTWP isn’t as strong as Jon and Dany’s, perhaps, but if Melisandre is suggesting that the promised prince may be multiple people, perhaps Tyrion will join them in being the third. It would definitely fit in with the secret Targaryen theory—maybe the Prince that Was Promised and the Three-Headed Dragon are one and the same, and that together Jon, Dany, and Tyrion will be the return of Azor Ahai. —Gabrielle Bruney
Arya will become Littlefinger
Although news seems to travel inexplicably fast in Westeros, it's possible that most of the south is unaware of Littlefinger's demise in the Season Seven finale. This would make it pretty convenient for Arya to travel to King's Landing (where Littlefinger used to have a great deal of power) using his face as a mask. Since she's the one who carried out the execution, it's likely Arya can use his as she did with Walder Frey's in the season premiere. Even if Littlefinger isn't exactly welcome in King's Landing at this point, it could be a convenient way for Arya to get close to the people on her kill list down south.
Arya kills Cersei
Arya has had Cersei on her kill list for a long time now. She will finally get her way in the final season, according to multiple fan theories. One points to a clue about Arya’s sword-holding hand. Maisie Williams told TVGuide back in 2011: "I'm right-handed, and when Mom was reading the first book, she told me about Arya being left-handed.”"
As a fan explains, the show creators have been liberal about making other changes from the book, so there must be a reason they insisted on Williams training with her left hand. Could it be because she will take on the identity of Cersei’s brother and former lover Jaime Lannister to kill her? Jaime lost his right hand in Season Three, so he’d have to kill Cersei with his left hand, thus making seasons of left-handed sword fighting make sense. —Kate Storey
Cersei's Pregnancy Will Kill Her
An important part of Maggy the Frog's prophecy is the declaration that Cersei will have three children, all of whom will die before Cersei. But at the end of Season Seven, our Queen is newly pregnant. There are a couple of ways to read this. The first, which was popular immediately following the revelation, was that Cersei was lying about her pregnancy. She needed to get—and keep—Jaime on her side, and thought that by telling him their family has another shot at a future, he'd stay. (This did not work, as we now know.) A fake pregnancy might also work as leverage in negotiations with her other brother, Tyrion. During a rare tête-à-tête with the youngest Lannister, she rubs her belly in such a way that Tyrion "can tell" she's with child. Tyrion always loved his nieces and nephews, and, as this theory points out, this might be what it takes to get Dany's Hand back in King's Landing. (Dany has told Tyrion she can't have children—so what future does her household have in maintaining the Iron Throne, anyway? Tyrion is constantly evaluating the stakes and chances, he might see counseling another young Lannister as the best path forward.)
But let's consider that the pregnancy is real. Does that discount Maggy the Frog's prophecy? Several Redditors have mused that Cersei could very well meet the same end as her mother: death in childbirth, which would uphold the dictum. In a warped way, it would be poetic. She'd still die by her brother—his child would kill her—and the forbidden relationship would have finally won out. It's just the sort of fatalism Thrones producers so love.
It's also worth noting, though, that Cersei has already (sort of?) broken the prophecy, even if she doesn't know it. It was revealed in Season One via a conversation with Catelyn Stark that Cersei did have a child with her husband, Robert Baratheon. (In the books, she and Jaime abort this pregnancy, but on the show, it's claimed the baby died very early on; many think that Gendry is actually this child and the rightful heir to Cersei's Iron Throne, which does discount the prophecy.) So it's also possible that Maggy the Frog's prophecy, which haunts Cersei's dreams, does only that.
The White Walkers Are Actually Good ... Because Bran
To be fair, we don't know much from the White Walkers's perspective. For all we know, they're traveling south to get rid of Cersei. But, let's consider for a second that the above Bran = Night King theory is true. That means poor Bran has found himself trapped inside a tool created with the singular goal of killing all humans, but he's still trying to stop the events he's set into motion. As one Reddit user wrote as part of a massive theory:
How do you protect life when you know the only thing you can do is bring death and when you know that no one has the power to stop you from inflicting it? Destroying the source of magic that keeps him bound to the curse: the main Heart tree at the Isles of Faces that is at the center of all Weirwood trees in Westeros and killing himself by killing Bran ... This is why the army of the dead completely turns around and goes back North when the Night King marks Bran. Because killing Bran is the priority ... Had they known, all Westerosi people had to do was let the Night King and the White Walkers pass through ... As a result, who would be the villain in this scenario? Is it the Night King and the Whitewalkers that killed tens of thousands so they could stop themselves from endlessly killing life? Or is it Jon/Bran & Co. that sent tens of thousands to their death instead of stepping aside like Sam did in his first encounter with a White Walker? One thing is for certain, knowledge would have been their true savior. Even with the most unlikely kind of people or thing, there may be common ground. In this case, both the Night King & Jon Snow were fighting for the same cause without realizing it: to protect the living.
Yeah, it's crazy, but George R.R. Martin does love to mess with the usual fantasy tropes. What better way than to make the horrible bad monsters the good guys?
Bran is the Night King
We know the Children of the Forest created the White Walkers thousands of years ago to protect themselves in a war against the First Men. Unfortunately, the Children of the Forest lost control of the White Walkers, who threatened to destroy every living thing. During the War Before the Dawn, the people of Westeros, alongside the Children of the Forest rallied to drive the White Walkers back and Bran the Builder constructed the wall to keep them at bay. Now, Bran has looked into the past, where he's witnessed the creation of the White Walkers and proved he has the ability to manipulate the past. If that's the case, it's possible that he might attempt to travel into the past and attempt to stop the creation of the Night King entirely, but in the process fuck it up and accidentally become the Night King himself. After this Night King theory got so insane that people were comparing the similarity between their clothes, Esquire asked actor Isaac Hempstead Wright about it.
"I personally think the Night King theory is a bit far-fetched, but I would have said the same thing about the Hodor theory," he told Esquire after Season Seven. "And when I saw that on paper, I was like, 'What! No way!' But this is Game of Thrones, and anything is possible. I'd love to be the Night King. That would be so fun to be like, 'It was me all along.' But I don't know—I doubt it."
Bran is the Prince That Was Promised and He and the Night King are ancient enemies
This theory is predicated on the recent interview Entertainment Weekly ran with Night King actor Vladimir Furdik, who said his character "has a target he wants to kill, and you will find out who that is. There’s also that moment [in “Hardhome”] when Jon Snow was on the boat and the Night King looked at him and raised his arms — there’s a similar and even stronger moment between Jon and the Night King this time."
So, let's now assume that this person the Night King is after is actually Bran aka the Three-Eyed Raven. Let's take into consideration everything we know happened during the long night and the climactic battle where the army of the living was saved by the Last Hero, who may or may not be the legendary Azor Ahai. As this theory speculates, maybe this Last Hero was the first Three-Eyed Raven, a.k.a. Bran the Builder, who drove the White Walkers back to save humanity. As one Reddit user writes:
So the last hero and the children ban together and create something that can defeat the NK. They gave this man the power he needs to put a stop to the NK. That's why the NK has tried to stop any three eyed ravens from being trained. That's why the NK killed Bloodraven and tried to kill Bran. That's why he is coming after Bran. That's why the NK and three eyed raven are ancient enemies!
Dan and Dave told us that the three eyed raven is not entirely human. Just like the NK. Both of them are not human because they were created by the children! All of the ancient past three eyed ravens, went inside of Bran when he uploaded all of the history of the world. All of the souls of the past three eyed ravens are now in Bran. So Bran is not Bran anymore he is all of the three eyed ravens in one mind. He's not exactly human anymore.
So, if Bran is the first Three-Eyed Raven, that means the Night King is marching toward killing Bran—possibly as revenge or, more likely, to defeat the only person with the knowledge or ability to stop him. It certainly would make for a great parallel if the Children of the Forest created both the Night King and the Three-Eyed Raven to balance out their own mistakes.
Bran Is Responsible for Ending the 300-Year Targaryen Dynasty
Okay, so if Bran is actually Bran the Builder and if he was able to manipulate past events, what if he was responsible for something that happened more recently, like send Aerys Targaryen into madness? As u/EaseGaming pointed out on Reddit:
We just watched the scene in which Jamie and Robert Baratheon were discussing the Mad King and the events around Jamie killing him. Jamie says that he kept saying "burn them all" even after he had stabbed him.
My girlfriend brought up a good question that I had never considered - is it possible that he had some sort of vision of the future and saw that the White Walkers were coming and that is what drove him mad? and as a result he was saying "burn them all" in regards to the White Walkers?
Now, taking this a step further, we know that history says that the Mad King Aerys Targaryen was known to hear voices. Is it possible that Bran traveled into the past and messed with Aerys Targaryen's mind as he did with dear, sweet Hodor? Consider Bran's motivations here. The Targaryen dynasty was the last time there was a unified Westeros. It's possible that he used his ability as the Three-Eyed Raven to convince Aerys to fight the White Walker threat using the full power of the Seven Kingdoms. Another reading of this could be that Bran knows he needs to manipulate Aerys in order to set this whole series of events into motion.
Bran Built the Wall
Season Six revealed that Bran Stark can not only see the past—he can manipulate it, too. There are a number of theories that consider the endless possibilities of his powers. Overall, they seem to connect Bran to every key moment in Westeros history. Bran already accidentally destroyed poor Hodor's mind by traveling to the past, and some speculate that he'll do the same thing to the Mad King Aerys Targaryen, who was known to "hear voices." To go back even further, it's been theorized that every person named Bran in Westerosi history is actually our Bran—meaning he actually built the wall.
Fans often point to this passage from George R.R. Martin's books:
"I could tell you the story about Brandon the Builder," Old Nan said. "That was always your favorite." Thousands and thousands of years ago, Brandon the Builder had raised Winterfell, and some said the Wall. Bran knew the story, but it had never been his favorite. Maybe one of the other Brandons had liked that story. Sometimes Nan would talk to him as if he were her Brandon, the baby she had nursed all those years ago, and sometimes she confused him with his uncle Brandon, who was killed by the Mad King before Bran was even born. She had lived so long, Mother had told him once, that all the Brandon Starks had become one person in her head.
It's the Cleganebowl ... bowl ... bowl ... bowl
Even though it didn't happen in Season Seven as everyone predicted, the epic showdown between Gregor and Sandor Clegane is almost certainly going to happen in the final season. In the Season Seven finale, The Hound tells The Mountain: "What did they do to you? Doesn't matter. That's not how it ends for you brother. You know who's coming for you. You've always known." This is almost certainly foreshadowing for the duel to come. The Cleganebowl, one of the most beloved Game of Thrones fan theories, has been brewing since Season One, when it's established that the two have hated each other since they were children, and The Hound's face is disfigured when The Mountain shoved him into a fire as punishment for playing with his toys.
Jaime will kill Cersei
It would be tragic, and beautiful, and satisfying all at once. Jaime must kill his sister/lover Cersei as she becomes the Mad Queen. In the Season Seven finale, Cersei tells Jaime that she plans to betray Jon and Dany even if it means the destruction of the human race. That was the last straw for Jaime, who finally left Cersei to head North—as actor Nikolaj Coster-Waldau told Esquire.com in an interview—before she could kill him. Now that they're on opposite sides of a war, Jaime might be forced to face, and even kill, his own sister. And there have long been hints to this happening: When Cersei was young, a seer named Maggy the Frog made the prophecy that Cersei would watch all her children die—only to be murdered herself. As the prophecy goes: "And when your tears have drowned you, the valonqar [High Valyrian for 'little brother'] shall wrap his hands about your pale white throat and choke the life from you." This would make for a rather bloody parallel to Jaime killing the Mad King during Robert's Rebellion.
Jon or Daeneys is the Prince(ss) Who Was Promised
Throughout George R.R. Martin's A Song of Ice and Fire is the legend of Azor Ahai, "a hero who fought against [the darkness] with a red sword" and "arose to give courage to the race of men and lead the virtuous into battle with his blazing sword Lightbringer." According to prophecy, "When the red star bleeds and the darkness gathers, Azor Ahai shall be born again amidst smoke and salt to wake dragons out of stone." Melisandre has been holding out for the return of Azor, whom she believed was Stannis Baratheon. Since Stannis didn't work out all too well, it's likely that her new hero is Jon Snow, whom she helped resurrect in Season Six. This theory took a twist in Season Seven, when it's pointed out that the translation of the prophecy could also mean the Princess That Was Promised, meaning it could be either Jon or Daenerys.
What if Sam is the one telling this whole story?
Who is telling this story? Is the narrator Jon? Is it George R.R. Martin? Is it Bran? In an interview a couple of years ago, John Bradley—who plays Sam—noted that it could be his character who is narrating the story. "One theory is that what we're seeing now and how we're experiencing Game of Thrones is Sam telling the story of Game of Thrones," he told The Hollywood Reporter. "If you take the logic of the story now, the story of Westeros and the story of the battle for the Iron Throne, it would be a book in that library." Fans have noted that in his scenes in the Citadel library in Oldtown, Sam can be seen standing under a gyroscope similar to the one shown in the Game of Thrones opening credits. In Season Seven, a conversation between Sam and Archmaester Ebrose seemed to confirm this theory, when Sam suggests a more poetic title for The Chronicles of the Wars Following the Death of King Robert I.
Look, the White Walkers are probably going to win
As we know all too well on Game of Thrones, our heroes almost never win. They die tragically and suddenly. Real justice is rare, if ever. So why should the ending of this saga be any different? And, let's face it, things aren't looking too good for Team Human. At the end of Season Seven, the Night King turned one of Daenerys's dragons into a White Walker dragon, then used it to demolish The Wall that had been keeping them out for thousands of years. So let's consider this for a second. If the Night King now has the ability to A) travel wherever he wants in Westeros by dragon and B) raise armies of undead using dead humans, what's stopping him from flying to every graveyard in the Seven Kingdoms and creating armies that overwhelm, surround, and destroy humans? At this point, given the constant bickering and manipulation in Team Human, who's to say the White Walkers shouldn't win?
