Warning: Spoilers ahead for “Game of Thrones” season seven.
“Game of Thrones” season seven may have left us with a lot of unanswered questions, but we haven’t stopped obsessing over every small detail and piece of foreshadowing in the series. Throughout the season, we analysed the callbacks and references hidden on each episode. Now, we’ve compiled a mega-list of the most important of these details.
Keep reading for a look at the 39 smaller moments you might have missed.
On the season premiere, the Valyrian steel blade used in Bran's assassination attempt was shown in one of Sam's stolen Citadel books.
Sam stole several books from the Citadel library's restricted section. And while he was flipping through the pages, we got a peek at a drawing of a very important weapon.
The dagger is often referred to as the 'catspaw blade' -- a reference to the would-be killer (or catspaw) who tried to kill Bran on season one. We knew the blade was made from Valyrian steel and had a hilt made of 'dragonbone,' but its origins have been a big mystery in the books and the show.
Based on Sam's book, it looks like we now know the blade is an ancient Targaryen weapon.
If you rewatch the moment when Bran gives Arya the dagger, it almost looks like he knows she will do something important with it -- like kill Littlefinger.
The actor who plays Bran, Isaac Hempstead Wright, told INSIDER he meant to hint at the blade's significance in that scene.
'Whether he knows that exactly or not, I think he looks at it and can see this that this dagger has a purpose, it has a fate, it has a destiny,' Hempstead Wright said. 'And that destiny is to kill Littlefinger (...) And that's why he gives it to Arya so suddenly. He's thinking, 'I don't know why, but you need this dagger.''
Ed Sheeran's cameo on the premiere featured more than just a lovely song -- the ballad had a huge significance in the book series.
In the books, Tyrion keeps his lover Shae in a house in King's Landing (not inside the Red Keep as Sansa's handmaid). This meant Tyrion would travel from the keep to her manse. A singer named Symon Silver Tongue befriended Shae and tried to blackmail Tyrion into helping him sing at the royal wedding -- or else he'd sing a song about Tyrion and Shae for all the world to hear.
Here are the song lyrics, written about Tyrion and Shae:
He rode through the streets of the city,
Down from his hill on high,
O'er the wynds and the steps and the cobbles,
He rode to a woman's sigh.
For she was his secret treasure,
She was his shame and bliss.
And a chain and a keep are nothing,
Compared to a woman's kiss
For hands of gold are always cold
But a woman's hands are warm
The 'hands of gold' refers to the chain Tyrion wore as Hand of the King -- the same chain he uses to kill Shae in the books.
In the books, Tyrion (and whoever is Hand of the King) wore a gold chain made from linked hands. He used that chain to murder Shae, and said 'for hands of gold are always cold' as he killed her.
The show changed up this scene slightly, since Symon Silver Tongue's song wasn't a part of the series -- until now. Ed Sheeran's cameo was a good opportunity to give book readers a hat tip.
Sandor Clegane's grave digging scene was yet another nod to book readers and it has to do with the most hyped theory of all time.
Sandor 'The Hound' Clegane was left for dead in both the books and on the show. Many people began theorizing about ways in which The Hound might return and one such theory was referred to as 'Gravedigger.'
In the books, Brienne of Tarth visits a monastery and speaks to the Elder Brother who claims to have found The Hound and laid him to rest. But Brienne spots a huge man (around The Hound's height) digging graves and notices that The Hound's horse is being kept in the stables nearby.
You can read the full theory here, but the point is that many believed Sandor Clegane was just disguising himself as a gravedigger in this monastery.
Cleganebowl postulates that Sandor and Gregor Clegane (The Hound and The Mountain) will fight to the death in an epic trial-by-combat. 'Game of Thrones' showrunners David Benioff and D.B. Weiss seem to be aware of this theory, because they have made allusions to it in the past through their writing.
Having The Hound literally digging a grave in the opening episode of season seven feels like one more not-so-sly reference to the fight of the ages fans are dying to see.
Remember when Tormund approached Brienne in the Winterfell courtyard? The episode's director told INSIDER what they talked about off camera.
'Sansa and Littlefinger are watching them from up on the walkway, and so we just shot (Tormund and Brienne) ad-libbing a bunch of conversations down below,' director Jeremy Podeswa told INSIDER.
Even though you couldn't hear what Tormund said to Brienne that makes her shake her head and turn away looking disgusted, Podeswa revealed the words that were exchanged.
'Tormund says something about his relationship with Sheila the Bear,' Podeswa said. 'And nobody knows what that means or what that's all about, so that's meant to make Brienne look at him askance. He's either trying to shock her or he's just oblivious that he's saying something that's crazy.'
Back on season four, Tormund and his fellow Wildlings -- including Ygritte -- are sitting around a fire.
'Did I ever tell you about her? Sheila?' Tormund asked the group. 'Oh, that was a night to remember. Of course, I'd had a good bit to drink. Her fangs were sharp, but she knew how to use them. And she was nice and soft down below. No, she was no ordinary beast.'
Ygritte interrupted the story. 'I know you never f----- a bear,' she said. 'You know you never f----- a bear. Right now, I don't want to think about the bear you never f-----.'
When the tactic of having Daenerys' dragons wreak havoc on King's Landing was suggested, Tyrion was quick to tell Dany that the last thing she wanted was to burn the whole city to the ground.
'You don't want to be Queen of the Ashes,' Tyrion told her.
This was a callback to Varys' warning to Olenna about Littlefinger. 'He would see this country burn if he could be King of the Ashes,' Varys said.
On season three, episode four, Varys and Olenna had a secretive conversation about where their loyalties lie. Varys warned Olenna not to trust Littlefinger, telling her that he would be King of the Ashes if he needed to.
Clearly everyone is steering Daenerys as far away from the other game-players as possible, including Littlefinger.
Speaking of Littlefinger, Jon choking the conniving lord was a direct mirror of Ned's encounter with him on the first season.
Littlefinger followed Jon into the crypts of Winterfell, where Ned Stark's grave marker stood (right next to Lyanna's, who is Jon's mother). When Littlefinger wouldn't stop talking about his love for both Catelyn and Sansa Stark, Jon shoved him up against the wall -- choking him.
Ned pulled the same move on Littlefinger when he thought he was lying about Catelyn being in King's Landing.
Littlefinger hid Catelyn inside one of his brothels when she came to King's Landing on the first season. When Littlefinger brought Ned to the door of a whore-house and claimed his wife was inside, Ned threw Littlefinger against the wall in a rage.
Stark men don't take kindly to the honour of their family being besmirched by the likes of Petyr Baelish.
On 'Stormborn,' Melisandre told Daenerys about Jon's accomplishments and why he could be a prophesied hero (you can read our full explanation of the significance of the prophecy here).
'As Lord Commander of the Night's Watch, he allowed the Wildlings south of the wall to protect them from great danger,' Melisandre said. 'As King in the North, he has united those Wildlings with the Northern houses so together they may face their common enemy.'
'He sounds like quite a man,' Daenerys replied.
On the fifth season, Sam read a letter to Maester Aemon.
'And though Daenerys Targaryen maintains her grip on Slaver's Bay, forces rise against her from within and without,' the letter said. 'She refuses to leave until the freedom of the former slaves is secure.'
'She sounds like quite a woman,' Sam said. Clearly the show was trying to draw as many parallels as possible between the Mother of Dragons and the King in the North.
Arya's reunion with Nymeria ended with a bittersweet goodbye. When Arya said, 'That's not you,' she was remembering a conversation she had with her father.
After trying to get Nymeria to come with her to Winterfell, Arya watched her full-grown direwolf leave. She smiled sadly and said, 'That's not you.'
Arya didn't mean that literally. She was referring to the fact that Nymeria wasn't some domestic pet that would follow Arya around anymore in the same way that Arya wasn't following the rules a high-born girl should.
Back on the first season, Ned and Arya had a heart-to-heart about her future as a lady -- and she rejected it, saying, 'That's not me.'
When Ned told Arya that Bran would grow up to be the lord of a castle, Arya asked if she could be a lord, too.
'You will marry a high lord and rule his castle,' Ned said. 'And your sons shall be knights and princes and lords.'
'No,' Arya replied. 'That's not me.'
The showrunners explained how Arya's attitude on the first season was mirrored in Nymeria's seventh season appearance.
'Arya's not domesticated and it makes total sense that her wolf wouldn't be either,' showrunner D.B. Weiss said in the 'Inside the Episode' segment after the credits.
We did the zooming and enhancing for you, and read the heartbreaking goodbye letter Jorah wrote to Daenerys.
Though a few words were unintelligible, the majority of Jorah's letter is visible:
I went to the Citadel in the last hope that the maesters could treat me as you ordered. Even with all their arts, I am beyond any cure out the grave. I have had a longer life than I deserved and I only wish I could've lived to see the world you're going to build, standing by your side. I have loved you since the moment I met you. If there's (….)
As Ebrose tells Sam that writing with style and accuracy is the key to making sure your work is read later, he says: 'I'm not writing 'A Chronicle of the Wars Following the Death of King Robert I' so it can sit on the shelf unread.'
When Sam makes an unimpressed face, Ebrose asked what he'd call it instead.
'Possibly something a bit more poetic?' Sam replied.
Some fans believe this was a hint at the idea that Sam Tarly is really the one 'narrating' George R.R. Martin's 'A Song of Ice and Fire' series (kind of like Bilbo writing 'The Hobbit' in Tolkien's universe). 'A Song of Ice and Fire' is certainly a more poetic name, so perhaps there's credence to this prediction.
By the end of season seven, 'Game of Thrones' confirmed that Jon Snow is actually half Targaryen. His father was Rhaegar Targaryen (Daenerys' brother) and his mother was Lyanna Stark (Ned Stark's sister). The shock of his first encounter with a dragon felt like a nod towards audience members in the know.
When Daenerys and Jon discussed Tyrion's love of talking, Daenerys said, 'We all enjoy what we're good at.'
'I don't,' Jon replied.
This was likely a reference to his skills with a sword -- we've watched as Jon has cut down many foes. But as Redditor King_Will_Wedge pointed out, this was also an accidental parallel to Jon's real father, Rhaegar.
'He liked to walk among the people, he liked to sing to them,' Barristan said.
Daenerys was surprised to hear about this side of her late brother.
'(Viserys) told me Rhaegar was good at killing people,' she said.
'Rhaegar never liked killing,' Barristan replied. 'He loved singing.'
Seems like Jon and Rhaegar have something in common.
The scene with Sansa ruling in Winterfell made a point to remind the audience that Maester Luwin kept records of every scroll, foreshadowing Littlefinger's plan.
A lot of fans noticed Littlefinger give Maester Wolkan some serious side eye when he said there are records of every message sent to Winterfell by raven.
'I'll check Maester Luwin's records -- he kept a copy of every raven's scroll,' Maester Wolkan said when Sansa asked about the previous winter lengths.
Later we learned that Littlefinger had Maester Wolkan find the scroll Sansa sent to Robb telling him to bend the knee.
Though Littlefinger's plot ultimately got him killed, the lead up to that reveal was riddled with confusing hints (or lack thereof).
Bran repeated the iconic 'chaos is a ladder' line back to Littlefinger, revealing that he knows about Lord Baelish's true intentions.
Petyr 'Littlefinger' Baelish tried and failed to rattle Bran by giving him the same blade used by the cutthroat to kill Bran on the first season. Then he tried to get Bran to divulge information about what he'd been up to beyond the Wall.
'To go through all of that and make your way home again only to find so much chaos in the world,' Littlefinger said. ' I can only imagine -- '
'Chaos is a ladder,' Bran said, interrupting.
This was what Littlefinger told Varys on season three, when he revealed that he had been manipulating Sansa and Joffrey the whole time.
For most of the earlier seasons, Littlefinger's motivations were mysterious. But he laid out his cards on the third season when he told Varys that creating chaos was his mechanism of ascending the rungs of power in Westeros.
'Chaos isn't a pit. Chaos is a ladder,' he told Varys. 'Many who try to climb it fail, and never get to try again -- the fall breaks them. And some are given a chance to climb, but they refuse. They cling to the realm, or the gods, or love ... illusions. Only the ladder is real, the climb is all there is.'
Knowing Bran had seen this conversation through his greensight visions, it meant he probably knew about everything Littlefinger had done -- including betraying his father Ned.
Arya's struggle with entering Winterfell was a perfect mirror to the first season when she accidentally left the Red Keep.
When Arya finally made it to Winterfell, she was stopped at the gates by two guards who refused to believe she was really Arya Stark. The same thing happened to her on the first season when she was chasing cats and got lost in the dungeons of the Red Keep.
Arya made her way through the Red Keep's sewers and finally got back around to the gates, but was laughed at by the guards there.
When she was younger, Arya used a lot more back talk to convince the guards that they'd better let her in the gates. But now on season seven, Arya's response to their disbelief was more measured and mature, relying on cleverness as opposed to an indignant attitude.
After the sack of Highgarden, the Lannister song 'The Rains of Castamere' played, and then Olenna repeated a line from the ballad.
When Jaime entered Olenna's room, she conceded defeat by repeating a line from 'The Rains of Castamere.'
'And now the rains weep o'er our halls,' she said.
This song has a significant meaning to the Lannisters. And while show-watchers will recognise the tune by now (it was played at the Red Wedding), you might not know the lyrics:
And who are you, the proud lord said, that I must bow so low?
Only a cat of a different coat, that's all the truth I know.
In a coat of gold or a coat of red, a lion still has claws,
And mine are long and sharp, my lord, as long and sharp as yours.
And so he spoke, and so he spoke, that lord of Castamere,
But now the rains weep o'er his hall, with no one there to hear.
Yes now the rains weep o'er his hall,and not a soul to hear.
For the full story of how 'The Rains of Castamere' was adapted for the show, read our interview with composer Ramin Djawadi.
Jon took Daenerys into the dragonglass caves to show her ancient drawings on the wall made by the Children of the Forest. Though the most interesting thing about them was the White Walkers depictions, there was also a spiral pattern that's been shown before on the series.
This spiral was seen on seasons three and five and seems to be a symbol for the Children of the Forest and the White Walkers.
We first saw the pattern on season three, when Mance Rayder called the White Walkers 'artists' because they left the carcasses of horses and men in a spiral shape.
The pattern appeared again on the fifth season when we watched the Children of the Forest create the Night King -- the very first White Walker -- by plunging a dragonglass dagger into his heart. He was tied to a tree that stood at the center of a rock formation in the same spiral shape.
The true significance of the pattern remains to be seen. But for now, it's a clear signal that something concerning the Children of the Forest or the White Walkers is brewing.
When Daenerys told Jon to bend the knee once again, she repeated the same question Jon had for Mance Rayder back on the fifth season.
Daenerys told Jon she'd fight for the North, but only if he bends the knee and swears fealty to her as the queen of all Seven Kingdoms.
'My people wont accept a southern ruler, not after all they have suffered,' Jon said.
'Isn't their survival more important than your pride?' she asked.
Jon had almost this exact same conversation, in reverse, with Mance Rayder -- the leader of the Wildlings.
When Stannis Baratheon arrived at the Wall and captured Mance Rayder, he told him he'd spare his life if Mance bent the knee. When Mance refused, Jon went to his prison cell to try and convince him to just swear fealty to Stannis and save the Wildlings from future suffering.
Here's how their conversation played out:
'Isn't their survival more important than your pride?' Jon asked Mance.
'Pride? F--- my pride,' Mance said. 'This isn't about that.'
'Then bend the knee and save your people,' Jon insisted.
'They followed me because they believed in me,' Mance said. 'Because they respected me. The moment I kneel for a southern king that's all gone (...) I'll be honest with you. I don't want to die. But it's better than betraying everything I believe.'
'And what happens to your people?' Jon asked. 'You preserve your dignity and die standing, and they will sing songs about you. You'd rather burn than kneel, a great hero. Until winter comes, and the White Walkers come for us all, and there's no one left to sing.'
'You're a good lad, truly you are,' Mance said. 'But if you can't understand why I won't enlist my people in a foreigner's war, there's no point explaining.'
Jon didn't try to explain to Daenerys why he won't bend the knee, but we can guess that he was thinking back to Mance's argument.
Though Jon didn't understand Mance's decision back on the fifth season, he's grown and learned more as a leader since then. He knows now what Mance meant. Betraying his people's trust and handing them over to a new, unknown ruler isn't worth the cost of their lives.
Jon eventually did bend the knee, though, so what does this conversation tell us about what is in store for season eight? That's one of many questions we have after season seven.
So far we've seen several new costumes for Daenerys on the seventh season - all of them evoking her Targaryen heritage and even hearkening back to her brother Viserys.
After speaking with costume designer Michele Clapton, we know that every detail of the costumes is meant to convey how the character is feeling or thinking, which is why we perked up when Daenerys was seen with a silvery-grey cape on this episode.
Prior to 'Spoils of War,' Daenerys has only worn red capes, the colour of the Targaryen sigil. But grey is one of the colours of House Stark. Is this just another monotone costume choice? Or were we meant to understand that Daenerys and Jon's relationship was becoming romantic?
While discussing Daenerys and her 'good heart,' Jon switch subjects to discuss strategy.
'How many men do we have in the north to fight (the Night King)? 10,000? Less?' Jon asked.
'Fewer,' Davos replied.
'What?' Jon said.
This was a reference to one of many jokes the fandom makes about Stannis -- his knack for correcting people who are using the word 'less' instead of 'fewer.'
On the second season, Davos told Stannis he didn't mind that his king had chopped off most of his hand. 'It's four less fingernails to clean,' Davos said.
'Fewer,' Stannis said, correcting him.
Then on season five, when Stannis and Davos were sitting in on a Night's Watch meeting about letting the Wildlings south of the Wall, Bowen Marsh argued they should just die.
'Less enemies for us,' Marsh said.
'Fewer,' Stannis said under his breath.
'What?' Davos asked.
'Nothing,' Stannis replied.
But based on the season seven episode, it looks like the lesson finally sunk in for Davos, who has become more and more literate as the series has gone on (mostly thanks to Shireen's teachings, R.I.P.). Now it's Jon's turn to learn the difference between 'less' and 'fewer.'
Gilly asked Sam if he was really ready to leave the Citadel. After all, becoming a maester was Sam's greatest wish when he was back at Castle Black.
'I'm tired of reading about the achievements of better men,' Sam said.
He was repeating what his now-dead father, Randyll Tarly, had sneeringly told him on the sixth season.
'I thought the Night's Watch might make a man of you,' Randyll told Sam. 'Something resembling a man at least. You've managed to stay soft and fat; your nose buried in books. Spending your life reading about the achievements of better men. I'd wager you still can't sit a horse, or wield a sword.'
Randyll was a cruel and emotionally abusive father to Sam. Clearly those cutting words are still weighing on Sam, even though he's grown much more confident and brave over the years.
When Gendry reappeared on the series after a years-long absence, fans noticed that he was repping his father King Robert Baratheon in more ways than one.
Gendry's tunic was likely a nod to the Baratheon colours, yellow and black. Plus the name Davos was giving him, 'Clovis,' could be a reference to King Clovis I -- a young French monarch who united the Frankish tribes under one kingdom. We doubt Gendry will make a claim to the throne, but there's no denying his royal blood.
The biggest deal was Gendry's new warhammer.
Gendry's new weapon of choice was a throwback to King Robert's preferred weapon and fearsome reputation.
Gendry even crafted a Baratheon stag sigil to wrap around the center of the warhammer. Now Gendry is putting his sentimental/badass weapon to use -- and he started with two Gold Cloaks.
One of the two Gold Cloaks killed by Gendry might have looked familiar. That's actor and comedian Kevin Eldon -- and he's appeared on the show before.
Eldon's brief appearance on 'Eastwatch' consisted mainly of him accepting a bribe of aphrodisiac crab, but he had a more significant cameo last season.
Arya was sent to watch this play several times on the sixth season. Eldron was playing an actor who was playing a rather offensive version of Ned Stark on stage.
On 'Beyond the Wall,' The Hound pointed out a mountain shaped like an arrowhead he'd seen in a fire-vision.
On season seven premiere episode, Beric and Thoros told the Hound to look into the flames. When he did, he saw a vision of a mountain where the dead were marching past.
Turns out we'd already seen that location before, back on the sixth season.
We saw this same location when Bran had a vision of the Children of the Forest creating the Night King, as Redditor Smurph269 pointed out. There was a rock formation in a spiral pattern -- the pattern the White Walkers now often repeat.
It's interesting to think Jon and company might have been heading straight for an area beyond the Wall with immense ritualistic meaning. Perhaps the Night King even led them there on purpose somehow? Then again, it's also possible the 'Game of Thrones' showrunners re-used a set in Iceland without realising it.
When Jorah was trying to bolster Thoros' spirits, he mentioned a historic battle known to book readers.
Jorah and Thoros were both present at the Siege of Pyke -- the final battle of Robert's Rebellion all those years ago. As Jorah said, Thoros was the first man through the walls, an act Jorah had taken for bravery but it turns out Thoros was black-out drunk.
That battle was where Jorah earned his knighthood, and it was also the fight in which Theon Greyjoy's father, Balon, was defeated yet again. At the battle's end, Balon was forced to give Theon to Ned Stark as a ward, setting in motion the eventual betrayal of Theon to the Stark family.
What's interesting about the various daggers and axes wielded by our group of heroes is that previously it wasn't established that dragonglass kills wights. We knew it killed White Walkers, but there's a difference between the two.
However on 'Beyond the Wall,' everyone from the Hound to Tormund was using dragonglass weapons against the horde of wights.
'Thank you, Dany,' Jon said.
'Dany? Who was the last person who called me that?' Daenerys asked. 'I'm not sure, was it my brother? Hmm. Not the company you want to keep.'
Interesting that Daenerys is either pretending not to remember or actually forgot about her brother's final words. It's likely not a coincidence that the last time Daenerys heard someone call her 'Dany,' it was another Targaryen.
Jon is really Daenerys' nephew, and if the show keeps heading in the same direction, he might even be her future husband. When they were younger, Viserys also told Daenerys they would marry -- keeping in tradition with the Targaryen culture so as to preserve their bloodline.
Another important moment was when Daenerys once again said that her dragons will be the only children she has.
'The dragons are my children,' Daenerys told Jon. 'They're the only children I'll ever have -- do you understand?'
And though he nodded yes, some viewers may be in the dark about this. Daenerys believes she's infertile after Mirri Maz Duur 'saved' Khal Drogo on the first season.
Mirri Maz Duur told Daenerys she'd save Khal Drogo's life -- but there was a terrible price. 'Only death can pay for life,' Duur said.
When Daenerys awoke and realised Duur had killed her unborn son, she asked to see Drogo. But the great Khal was effectively in a vegetative state -- alive but without life. Daenerys asked Duur when he would return to her.
Here, the show omitted a significant portion of Duur's reply. But this is what she said in the books:
When the sun rises in the west and sets in the east
When the seas go dry and mountains blow in the wind like leaves
When your womb quickens again and you bear a living child
Then he will return, and not before.
For a longer look into Daenerys' ability to conceive (and why she might be wrong about that), read our full explainer here.
On the finale while trying to win Cersei's trust, Jon Snow warned her that the real enemy wouldn't negotiate.
While speaking of the Night King and his army, Jon assured Cersei that they were dealing with 'a general you can't negotiate with.'
He meant that literally. According to the 'Game of Thrones' showrunners, the Night King will never speak.
After the season six finale, David Benioff and D.B. Weiss said the Night King wouldn't have any lines on the show.
'We don't think of the Night King as a villain as much as Death (...) In some ways, it's appropriate he doesn't speak,' Benioff and Weiss told Deadline in 2016. 'What's Death going to say? Anything would diminish him. He's just a force of destruction. I don't think we've ever been tempted to write dialogue for the Night King. Anything he said would be anticlimactic.'
Later in the dragonpit, Daenerys said a phrase in High Valyrian we last heard on season three: 'A dragon is not a slave.'
'A dragon is not a slave,' Daenerys told Jon, first in High Valyrian and then again in the Common Tongue.
This was a callback to the epic moment when Daenerys bought the Unsullied in Astapor on the third season.
Daenerys tricked the slave master into believing she was trading one of her dragons for the Unsullied.
When Daenerys handed Drogon on a leash to one of the slave masters, he struggled to get the dragon under control. Remember, the slaver believed Daenerys only spoke the Common Tongue. He frequently said horrible things about her in High Valyrian while standing right next to her.
'Tell the bitch her beast won't come,' the slaver ordered of Missandei.
That was when Daenerys turned around and said, in High Valyrian, 'A dragon is not a slave.'
Daenerys replied with one of her most epic speeches in the series:
'I am Daenerys Stormborn of the House Targaryen, of the blood of Old Valyria. Valyrian is my mother tongue. Unsullied! Slay the masters, slay the soldiers, slay every man who holds a whip, but harm no child. Strike the chains off every slave you see!'
Then she turned back to the slave master and simply said, 'Dracarys.'
Drogon roasted him on the spot.
Jon called out Daenerys' assumption that she's infertile, which may be a foreshadowing of a future Jon and Daenerys love child.
'Has it occurred to you she might not have been a reliable source of information?' Jon says of Duur.
As we noted in our earlier theory breakdown about Daenerys' ability to have children, she might not be barren after all. If Jon gets Daenerys pregnant, that would be a real Targaryen incest twist.
Speaking of Jon's secret bloodline, his conversation with Theon on the finale foreshadowed the identity crisis he'll surely face next season.
Theon lamented to Jon about his struggles with identity growing up as the ward of Ned Stark.
'It always seemed like there was an impossible choice I had to make: Stark or Greyjoy,' Theon said.
'Our father was more of a father to you than yours ever was,' Jon said. 'But you never lost him. He's a part of you. Just like he's a part of me. You don't need to choose. You're a Greyjoy and you're a Stark.'
Jon assured Theon that the nurture he received from Ned Stark was just as important to his character as the blood that runs in his veins.
Jon himself will be confronted with these struggles of identity in the eighth and final season once he finally learns that he's the son of Rhaegar Targaryen and Lyanna Stark. Jon Snow isn't even his true name -- it's Aegon Targaryen.
But Jon's entire identity is wrapped in his bastard name of Jon Snow. Read our full explanation of why Jon's 'true name' will likely never be adopted by him for more on this.
Rhaegar was the oldest brother of Daenerys and Viserys. In his season seven appearance, he looked strikingly similar to Viserys. This makes sense because Viserys would have emulated his older brother, the heir to the Iron Throne.
Rhaegar was played by Welsh actor Wilf Scolding, though clearly the costume designers took care to style him very similarly to Viserys.
This similarity is straight from the books. When Daenerys has a vision of Rhaegar, she nearly mistakes him for Viserys.
'The man had her brother's hair, but he was taller, and his eyes were a dark indigo rather than lilac,' George R.R. Martin wrote.
In another familial parallel, Arya and Sansa stood in the same spot Sansa and Jon were on during the season six finale.
For their post-Littlefinger-murder cool down, Arya and Sansa stood on the battlements of Winterfell. There they discussed their father Ned and the importance of family, much in the same way Jon and Sansa did after the Battle of the Bastards.
When Jon and Sansa were last there, Jon emphasised how important it was for them to trust each other.
It seems fitting that now Arya would get a turn at having a Sansa heart-to-heart. This also draws a deeper connection between Jon and his Stark cousins who he's always regarded as half-siblings.
We also hope this is a foreshadowing of Jon and Arya's pending reunion on the series.
Arya and Sansa repeated Ned Stark's words. 'In winter we must protect ourselves,' Arya said. 'Look after one another.'
Arya was repeating a lesson her father taught her on the first season, after Arya said she hated Sansa. Arya had been furious with Sansa for siding with Joffrey over the murder of her friend Mycah.
'In the winter, we must protect ourselves -- look after one another,' Ned told Arya. 'Sansa is your sister.'
In the books, Ned continues speaking in this scene with Arya. But the show didn't include this line. Instead, Sansa said it for the first time on the season seven finale in response to Arya.
'When the snows fall and the white winds blow, the lone wolf dies, but the pack survives,' Sansa said.
We hope this means the Stark in-fighting will end with this season. Jon is on his way back to Winterfell. And though Sansa appeared less-than-thrilled when she heard about Daenerys, we're hoping they still consider Jon to be a part of their wolf pack.
Last but not least, we were all concerned for Tormund and Beric Dondarrion in the devastating final scene.
But if you rewatch the scene, both Tormund and Beric are away from the edge of the part of the Wall that collapses. So they likely survived, even though undead-Viserion's crazy blue flames had us worried.
And when the angle pulled back, you could see a section of the Wall still standing with small structures on top.
Of course, Beric and Tormund might still be stranded atop the Wall. Plus this means that they're behindthe army of dead who just marched through the new gap in the Wall. So we're not sure how they'd re-enter the fold on season eight, but at least we're pretty confident they're still alive.
'Game of Thrones' might not return for its eighth and final season until 2019. But until then, read our roundup of every major question we have heading into season eight.
