House of the Dragon: Season 3 Episode 7 ‘The Dragon in Winter’ explained

Warning: Major spoilers ahead

Helaena dreams of tending to a grey mare in the courtyard, where the gates to the keep swing open for her. She is awoken by Rhaenyra, who has come to check on her and ask for information. The pair talk about the power of dragons, and whether they have the ability to alter someone. Rhaenyra insists she hasn’t changed, but Helaena isn’t so sure, and focuses on her tapestry as she avoids answering her half-sister’s questions directly.

Rhaenyra tells her she believes she is a dreamer, asking what she last saw, but she’s unimpressed by her answer of “a grey mare”. She continues to push Helaena, questioning what she’s seen about the war, those fighting against her, and those around her. When Helaena says she doesn’t know, Rhaenyra begins to get agitated, questioning if she’s lying or just doesn’t want to tell her.

Snatching away her tapestry, Rhaenyra gets physical with Helaena, desperate for some kind of sign that the war will turn out in her favour. But Helaena doesn’t respond, and Rhaenyra retreats.

Elsewhere, during their latest search for Vhagar in the Riverlands, Baela speaks with Addam about their shared frustrations with Rhaenyra. Addam shares Corlys’s hopes that he and brother Alyn be legitimised, wondering if she might put in a good word with the Queen. She gently breaks it to him that she does not hold much sway with her stepmother, but he argues that perhaps her father might be persuaded to argue in their favour. When she asks why he wants to be legitimised so badly, he flirts on the subject of a marriage to a highborn lady. Baela mistakenly thinks he’s been told about her dalliance with Alyn, only realising her mistake when she sees the shock on his face.

Before either can say anything, they spot a dragon in the distance – Addam questions if it’s Vhagar, but Baela recognises it from the Gullet.

At the small council meeting, Rhaenyra’s advisors are furious. After she directed the smallfolk to direct their issues to master of coin Tohrren Manderly, his house has been defaced with bodily fluids. Rhaenyra’s not sure what he expects her to do about it, but he’s aware he’s being used as a scapegoat.

When she asks about Harrenhal, there is no news, and she’s unnerved that Daemon has gone off on a “personal errand” which no one knows about. The only piece of good news for Rhaenyra is from Alyn, who assures her that the army is close to Tumbleton, and that Velaryon men are arriving to police King’s Landing within the next day or two. And the only person who gets a positive outcome from the meeting is Sabitha Frey, whom Rhaenyra finally gifts Harrenhal.

When Baela and Addam arrive with news, she hopes it’s about Vhagar – but instead she’s informed of the pair spotting Sheepstealer… with a rider.

After the meeting, Mysaria uses the new information to fuel Rhaenyra’s distrust of Daemon, noting how he must have lied about his claim he killed Sheepstealer’s rider to appease her, and listing his other faults in the process. Rhaenyra is hesitant to hear it, but she struggles when Mysaria questions if there was anything she believed Daemon was incapable of doing.

When Rhaenyra leaves, Mysaria invites Lady Sylvi – the madam of a brothel in King's Landing and one of her most prized informants - to the throne room and they speak about Rhaenyra’s rule. Mysaria shares Rhaenyra doesn’t want to hear anymore petitions, and both agree it’s a mistake, with her people now scared to leave the house at night with sinister forces at play in the city. Mysaria offers to hear the petitions quietly and push forward their agenda to Rhaenyra when she’s in a better mood.

Sylvi questions the change in Mysaria now she’s got a position in the castle, and how she’s grown to thrill in the power that she has. Mysaria tries to deny it, but Sylvi warns her that she needs to remember that the castle isn’t made of her people. She correctly guesses Mysaria called her there so she can be applauded for her position, but Sylvi refuses to give it to her.

In her dreams, Helaena dreams of giving birth to a boy, who is immediately taken from her by a guard. She then rides on Dreamfyre, burning hundreds of men as they charge at her. Another vision sees her with two children feeding chickens in an idyllic farmyard setting, only to have the vision distort as night and snow falls around her, wiping the vision away into blackness.

Aemond continues to recover at Harrenhal, training himself with a sword beforesuccumbing to his pain. But he gets a surprise when his mother, Alicent, appears before him, saying she’s escaped from King’s Landing and has come to join him.

She tells him how proud she is of him for going undetected and embraces him as “her best and truest son”. She claims he is all she has left, with Aegon likely dead. Emotionally, she claims she has failed him, prompting him to console her, and she responds by leaving into a kiss, which becomes passionate and they begin to have sex. However, halfway through, it’s revealed to actually be Alys, who has tricked him into bed in a bid to become impregnated with his child.

He hurriedly pushes her off in shock and leaves – only to run into the real Alicent outside. After what’s just happened, he’s clearly untrusting, not listening to what she’s saying and believing her to be an illusion, even grabbing her to check that she’s real. Just when he’s about to believe her, she holds his face and tells him “you’re all I have left” and he’s uncertain again.

When she introduces him to her guide, Ser Adrian, Aemond feints hospitality only to stab him in the neck, horrifying Alicent. He says that he can’t trust a stranger with the secrets Harrenhal keeps. Alys arrives – displeased by the new arrival – to tell them that supper is served.

As the three sit down for dinner, Alicent is baffled by Alys’s presence, wanting to know who she is and how she has such a hold over Aemond. But Aemond shares his plans to take Harrenhal as his seat, remain there with Alys, and rule his own kingdom from there.

Alicent questions that decision – Rhaenyra could attack at any time – but he is undeterred, believing that although she has dragons, they are ridden by “commoners” and she’s secured her own downfall. He is looking forward to a future with his own kings in the making, and insists Alicent stay with them.

Alys tells Aemond they’re out of firewood, and he angrily leaves the table to cut some more. She then uses the opportunity to warn him that Alicent is there to do him ill, but he refuses to listen, believing Alys is jealous and warns her to keep her dark thoughts to herself.

While they’re arguing, Alicent heads to the body of Ser Adrianand retrieves his knife - and while doing so sees a particular kind of berry growing nearby... one she last saw in the Godswood with Heleana - Nightshade. She later visits Aemond with a goblet of spiced wine. She soothes him and tells him to ignore Alys’s warnings and go with his own instinct.

Alicent is later seen hurrying to the stables. Aemond, now feeling the effects of the poisoned wine, collapses in front of Alys once again. Alys irritably calls him an idiot.

After their success at the Butcher’s Ball, Roddy the Ruin and the Black army march forward towards Tumbleton – with Ser Criston’s head on a pike.

Ser Gwayne rushes to Ormund to share the news that the army is now just a day away from reaching the town and battle is imminent, but Ormund is unconcerned. Dismissing Ser Criston for “dying in the mud for nothing”, he teases he has “a new piece on the board that will bring Rhaenyra to her knees”.

At dinner, Ormund entertains Lord Corlys, who he’s now holding hostage after the altercation in the woods. But Corlys is untrusting, refusing to eat or drink what he’s given, and questioning what Ormund’s up to. Ormund says he hopes Corlys will be of assistance to him. While it won’t make Rhaenyra give up her crown, his imprisonment will prevent his Velaryon army from attacking under the risk of killing their leader, and encourage them to step down from their position in King’s Landing so disorder can continue within its walls.

Ormund questions how Corlys could stay loyal to the Targaryens after what he has been through, mentioning how his late wife Rhaenys was a victim of a family that "devours their own". Having heard enough, Corlys excuses himself to return to his cell.

Later, in King's Landing, Alyn receives a box from a messenger – containing Corlys’s finger, complete with his ring.

Daeron, who was present at the dinner, relays the update to Gwayne, who is confused why unrest in King’s Landing is so important to Ormund, and if that’s really the “new piece on the board” he was told about. Daeron vents his frustrations about Ormund being so controlling and shares his sympathies to Gwayne for the loss of Ser Criston, who he is mourning.

Daeron offers to make the army surrender, but Ser Gwayne knows it's pointless and Ormund is in too deep to give up, and they would all hang regardless. Ser Gwayne suggests Daeron flee on his dragon, Tessarion, but that’s also not possible as he would be seen as a king that would abandon his people to ruin, leaving no one to take him in. He opines that Rhaenyra could take his crown for all he cares.

But it turns out Corlys was not the only new piece on the board Ormund had teased. In a covert meeting outside Tumbleton, Ulf shares a mug of ale with the Hightower Lord, who flatters the dragonseed and offers sympathy for his appalling treatment from Daemon and his unjust banishment from taverns. Ormund gives Ulf an offer: join their side, and in return he can have Corlys' hold of Driftmark, and a new title: Lord of the Tides. Ulf accepts, telling him everyone who laughed at him before will burn.

Daemon heads to see Lady Arryn at the Eyrie, and demands to see his daughter, Rhaena. But she’s not there, having fled on Sheepstealer, exiled by the Lady of the Vale.

While she promised Daemon she would remain hidden, Lady Arryn shares Rhaena has not kept her word, with the Vale now abuzz with rumours of “a wild girl riding a dragon while living amid nettles and sheep”. She’s done with Rhaena and her behaviour, and wants nothing to do with hiding her anymore, even saying she plans to tell Rhaenyra. Daemon requests to have a day to try and get Rhaena under control, and Lady Arryn obliges, suggesting his daughter has been looking for the still-missing Vhagar.

On Caraxes, Daemon is able to track down Rhaena and get her to ground, furious with her for not listening. Rhaena warns him to stay back as Sheepstealer doesn’t heed her. Sheepstealer charges, knocking Daemon to the ground. Caraxes tries to retaliate, but Daemon calms him.

Daemon warns that word has gotten back to Rhaenyra about Sheepstealer still being alive, and she needs to go into hiding, but she refuses. She wants to find Vhagar, hoping killing her will win her back some favour in Rhaenyra’s eyes.

To her surprise, he offers to help her, and admits he failed her as a father, especially as he grew up similar to her – without a dragon and without a mother.

But two more dragons arrive on the horizon – Addam on Seasmoke, and Rhaenyra on Syrax. Rhaena thinks he trapped her, but he insists he didn’t summon them and tells her to run on foot before she is spotted. She does as she’s asked, but Addam gives chase as he lands, leaving Rhaenyra with Daemon.

Rhaenyra demands to know who the rider is and why Daemon has protected them. Addam drags Rhaena kicking and screaming back to the group. Rhaenyra is heartbroken as she discovers the truth, that Rhaena is behind her son Jace’s death and Daemon knew – but as Rhaena accepts her fate and kneels before the queen for her punishment, they’re distracted as Sheepstealer attacks Syrax.

Daemon manages to mount Caraxes, and Addam gets to Seasmoke, both attack Sheepstealer to get Syrax the injured Syrax to safety. Rhaenyra commands Rhaena to join her on Syrax and they escape, and Daemon encourages Addam to escort the Queen to safety, leaving him and Ceraxes to kill Sheepstealer.

He is thrown off his seat in the vicious fight, and Sheepstealer - gravely injured, but alive - limps off, with Daemon ultimately allowing it for the sake of his own dragon.

On arrival back at King’s Landing, Rhaenyra commands Rhaena be sent to a room but refuses to look at her. That evening, as Daemon comes home, he tries to explain he was only trying to protect his daughter, which offends Rhaenyra, questioning what he thinks she’s capable of. He says she should at least know now it was never a scheme against her.

Baela goes to visit Rhaena, and while she initially looks angry, declares her sister will “begin anew” now.

Unable to sleep, Rhaenyra visits Mysaria to update her on what happened, and she notes that she was right about Daemon’s deception. Rhaenyra calls out her advisor out for trying to turn her against Daemon deliberately so she can twist her into what she wants.

Dejected, Rhaenyra says nothing is turning out the way she needs it to, prompting Mysaria to “pour honey in her ear”. She encourages her to hold on and calls her worthy of the throne. They then sleep together.

After their time at Rook’s Rest, Larys, Aegon and Tyland ride with two guards towards Maidenpool in their bid to get to Braavos. Tyland is still insistent they reconsider their decision to head out of Westeros, but Aegon is insistent, though is far from happy about the long journey ahead.

The group are distracted when they see peasants fleeing their homestead, and when they ask a woman what’s going on they discover the Mootons – a house sworn to Rhaenyra – have dispatched their thousands-strong army and are going town to town looking for Tyland – whom the crown assumes will know about the missing treasury. Aegon is sure they can’t have heard about him, but as hundreds of smallfolk block their way, they need to come up with a plan to keep him safe and undetected quickly.

They decide to turn back to Rook’s Rest, only to discover the refugees evacuating there as well as the Mootons arrive. Tangletongue, who is among those fleeing, asks where Janos is as he assumed he was with them. They deny all knowledge.

Larys suggests Tyland turn himself in. Staying on the run with a wanted man puts Aegon at risk and it may buy them some time to escape. Tyland is less than keen.

Aegon has another idea. He tells them both to flee, and leave him where he is – he’s done running, and is ready to die if need be, just not as an unknown fugitive. He wishes to take a stand and be buried as a king at Rook’s Rest next to his beloved dragon, and have it known in the history books that he wasn't killed by his own brother. Tyland says if that’s what the king wants, then he will remain and die with him, as he won’t have him be slain by an army meant for him. Larys bids them both good luck but decides to take Aegon’s offer to run. He offers to stay if Aegon commands it, but Aegon lets him go.

As night falls, Tyland and Aegon wait as they see the men approach. They ready themselves for “their final stand” and are ready to accept their fate as the army approaches. Aegon briefly panics and considers fleeing, but after a moment to gather himself, stands up and refuses to swear fealty to Rhaenyra.

As swords are drawn in preparation for battle, Aegon reveals who he truly is. In a thundering speech, he states he was made King by the High Septon in the light of The Seven and whoever strikes him down will face the true judgement.

While he speaks, the thousand-strong army suddenly looks terrified and retreats – as Aegon declares he’s finally being seen as “righteous and glorious… who he truly is.”

But it’s not Aegon’s powerful words that struck fear into the men… it’s because Sunfyre, Aegon’s dragon everyone thought dead, has returned to his master, and stands behind him. Aegon is just as shocked as everyone but delighted.

Sunfyre - every bit as scarred and deformed has his master - sets the entire army ablaze, leaving Aegon laughing hysterically.
