DAENERYS Targaryen isn't the only one with a dragon at her disposal after the events of today's new episode of Game of Thrones.
In Beyond the Wall, Jon Snow and his rag-tag group - dubbed the 'Suicide Squad' - ventured north of the wall for their daring plan to capture a white walker to prove their existence to Westeros.
After a few casualties, and facing off against a dead bear, the group did indeed capture a white walker. But it was a trap that forced the group into the middle of a frozen lake.
Surrounded by thousands of white walkers, they sent word to Daenerys - who rode in to save the day with her three dragons.
Little did she or Jon Snow know the Night King's spears can kill dragons - putting Cersei's dragon machine to shame.
The group successfully flees on the back of a dragon, Daenerys devastated at the death of one of her children.
But just like the bear, the Night King brings back dragon. Only next week's season finale will reveal what a white walker dragon can do.
The dramatic events and Jon Snow's latest brush with death has also functioned to bring him and Daenerys closer together. Seeing the Night King's powers for herself, she vows to defeat him and Jon finally swears his allegiance.
In Winterfell, the only other location to feature heavily in today's episode, tensions are at an all-time high between sisters Sansa and Arya as they try to figure out each other's true intentions. Littlefinger's plan, whatever it is, appears to be working.
Here are the key scenes from this week's episode:
The differences between the Stark daughters could not be any more... stark.
Arya discovered the short letter Sansa wrote when she was with Joffrey. Forced to pen Cersei's words, Sansa's letter requested that Robb swear fealty to avoid a war between Starks and Lannisters.
Arya, who had no knowledge of the circumstances, confronted Sansa.
She accused the Lady of Winterfell of working alongside, or even for, the Lannisters. Arya didn't accept Sansa's reasons - the young assassin has no knowledge of the reality Sansa faced.
All she saw was a letter that betrayed House Stark, and that was enough to feed her anger and distrust.
Arya went so far as to blame Sansa for standing idly by as their father Ned was executed at King's Landing.
Sansa didn't take it lying down.
Surprised to learn Arya witnessed the former King's execution, Sansa pressed the assassin on why she didn't act.
The relationship breakdown is exactly what Littlefinger had planned for.
Sansa sends Brienne to King's Landing at the Queen's invitation, much to the swordswoman's dismay. Brienne rallied to stay but Sansa stuck to her guns.
Later, Sansa discovered Arya's faces.
The Lady of Winterfell was looking through the assassin's room when she found two of her faces.
It was the first time Sansa had the chance to understand where Arya had been, but she was clearly frightened.
How do you react to learning your sister is an assassin who can wear other people's faces?
Arya has clearly put Sansa on notice, but what happens next could be a game changer.
Dany and Tyrion
Daenerys is blatantly ignoring Tyrion. The relationship has changed from a fair balance, during which she came to him for answers and truly listened to what he had to say, to her taking the reins and trusting only herself.
The dwarf took Varys' advice from last week, which was to try to make Daenerys listen his counsel.
While he tried, it wasn't overly successful.
The arrival of a raven, sent by Gendry, tested both sides.
Tyrion argued they must not do a thing.
The Mother of Dragons had no intention of doing nothing. She and her three dragons left Dragonstone immediately, on their way to rescue Jon and his company.
North of the Wall
The company led by Jon Snow, which included the likes of Gendry, The Hound, Beric Dondarrion and Jorah Mormont, spent much of the first half of the episode trading insults and friendly banter as they searched for the white walkers.
The plan was to deliver a wight to King's Landing in order to receive reinforcements at the Wall.
As the group captured an undead soldier they learned what could be majorly beneficial in the battles to come: the death of one white walker can destroy the wights they resurrected.
The arrival of a horde saw Snow send Gendry back to the Wall. While the Baratheon bastard wanted to fight, Snow said Gendry was the fastest of the group, and would be best positioned to send ravens to Dragonstone.
The Hound commandeered his battle axe, and, without another word, Gendry was off.
While Gendry was successful, the rest of the group encountered an army unlike anything it's ever faced.
Trapped in the centre of an icy lake, they endured a lengthy stalemate.
The undead could not cross the ice, which cracked under their weight, and there was no way out for Snow's company.
It was here Thoros died, his body burned to ensure he couldn't turn.
The stalemate was broken when a rock thrown by Clegane skipped along the surface. It proved the ice had frozen, allowing the undead to march.
Tormund almost met his end. He was set upon by white walkers, who dragged him towards the icy water.
Clegane, who had earlier bonded with Tormund over Brienne, rescued the wildling just in time.
When all seemed lost, Dany arrived with Drogon, Rhaegal and Viserion in tow.
They made quick work of hundreds of undead soldiers, and Dany landed to give the remaining members of Snow's company their ticket out of there.
Nothing could prepare them for the Night King's next move.
He threw a spear which found Viserion, grounding the giant dragon and killing one of Daenerys' "children".
It's the first time we've seen a dragon felled in the series, and its lasting effect on Dany is reserved for next week's season finale.
Snow, who was presumed dead again, was rescued at the last moment by Benjen Stark, who sacrificed himself to save the King in the North.
But the Night King wasn't finished.
Undead soldiers dragged heavy chains to pull the dead dragon's body from the lake, and as the Night King approached it was a scene we've seen before: he resurrected Viserion, giving the undead army a weapon unlike any that has been unleashed before.
It was an emotional roller coaster for fans, who took to social media to discuss the jam-packed episode:
