Hi Anon and thank you for the question! 🥰 I love the question because Jonrya is chockful of canon content straight from the books, and this isn’t even including George’s 1993 original outline. We have to thank George RR Martin for that. And surely, with Jon’s death, Arya will be thinking of him a lot in TWOW. In the 5 released books, they have so many moments and memories about one another that serves as a firm foundation for both of them to be each other’s favourites and the person they love and miss the most with all their heart. Let’s do a countdown, shall we? Not necessarily in order.

10. At the crypts

Robb took them all the way down to the end, past Grandfather and Brandon and Lyanna, to show them their own tombs. Sansa kept looking at the stubby little candle, anxious that it might go out. Old Nan had told her there were spiders down here, and rats as big as dogs. Robb smiled when she said that. “There are worse things than spiders and rats,” he whispered. “This is where the dead walk.” That was when they heard the sound, low and deep and shivery. Baby Bran had clutched at Arya’s hand.

When the spirit stepped out of the open tomb, pale white and moaning for blood, Sansa ran shrieking for the stairs, and Bran wrapped himself around Robb’s leg, sobbing. Arya stood her ground and gave the spirit a punch. It was only Jon, covered with flour. “You stupid,” she told him, “you scared the baby,” but Jon and Robb just laughed and laughed, and pretty soon Bran and Arya were laughing too.

9. The closest of their siblings and defending each other

…A dozen spectators, man and boy, were calling out encouragement, Robb’s voice the loudest among them. She spotted Theon Greyjoy beside him, his black doublet emblazoned with the golden kraken of his House, a look of wry contempt on his face. Both of the combatants were staggering. Arya judged that they had been at it awhile.

“A shade more exhausting than needlework,” Jon observed.

“A shade more fun than needlework,” Arya gave back at him. Jon grinned, reached over, and messed up her hair. Arya flushed. They had always been close. Jon had their father’s face, as she did. They were the only ones. Robb and Sansa and Bran and even little Rickon all took after the Tullys, with easy smiles and fire in their hair. When Arya had been little, she had been afraid that meant that she was a bastard too. It had been Jon she had gone to in her fear, and Jon who had reassured her.

…

Reluctantly, Arya surrendered her sword, wondering if she would ever hold it again. Her father turned it in the light, examining both sides of the blade. He tested the point with his thumb. “A bravo’s blade,” he said. “Yet it seems to me that I know this maker’s mark. This is Mikken’s work.”

Arya could not lie to him. She lowered her eyes.

Lord Eddard Stark sighed. “My nine-year-old daughter is being armed from my own forge, and I know nothing of it. The Hand of the King is expected to rule the Seven Kingdoms, yet it seems I cannot even rule my own household. How is it that you come to own a sword, Arya? Where did you get this?”

Arya chewed her lip and said nothing. She would not betray Jon, not even to their father.

…

“Lumpyhead,” corrected Lommy. “He prob'ly stole it.”

“I did not!” she shouted. Jon Snow had given her Needle. Maybe she had to let them call her Lumpyhead, but she wasn’t going to let them call Jon a thief.

8. The woman is important too!

She watched her little brother whack at Tommen. “I could do just as good as Bran,” she said. “He’s only seven. I’m nine.”

Jon looked her over with all his fourteen-year-old wisdom. “You’re too skinny,” he said. He took her arm to feel her muscle. Then he sighed and shook his head. “I doubt you could even lift a longsword, little sister, never mind swing one.”

Arya snatched back her arm and glared at him. Jon messed up her hair again. They watched Bran and Tommen circle each other.

“You see Prince Joffrey?” Jon asked.

She hadn’t, not at first glance, but when she looked again she found him to the back, under the shade of the high stone wall. He was surrounded by men she did not recognize, young squires in the livery of Lannister and Baratheon, strangers all. There were a few older men among them; knights, she surmised.

“Look at the arms on his surcoat,” Jon suggested.

Arya looked. An ornate shield had been embroidered on the prince’s padded surcoat. No doubt the needlework was exquisite. The arms were divided down the middle; on one side was the crowned stag of the royal House, on the other the lion of Lannister.

“The Lannisters are proud,” Jon observed. “You’d think the royal sigil would be sufficient, but no. He makes his mother’s House equal in honor to the king’s.”

“The woman is important too!” Arya protested.

Jon chuckled. “Perhaps you should do the same thing, little sister. Wed Tully to Stark in your arms.”

“A wolf with a fish in its mouth?” It made her laugh. “That would look silly. Besides, if a girl can’t fight, why should she have a coat of arms?”

Jon shrugged. “Girls get the arms but not the swords. Bastards get the swords but not the arms. I did not make the rules, little sister.”

7. Seeing one another in other people

“NO!” Arya and Gendry both said, at the exact same instant. Hot Pie quailed a little. Arya gave Gendry a sideways look. He said it with me, like Jon used to do, back in Winterfell. She missed Jon Snow the most of all her brothers.

And…

Ygritte watched and said nothing. She was older than he’d thought at first, Jon realized; maybe as old as twenty, but short for her age, bandy-legged, with a round face, small hands, and a pug nose. Her shaggy mop of red hair stuck out in all directions. She looked plump as she crouched there, but most of that was layers of fur and wool and leather. Underneath all that she could be as skinny as Arya.

…

“If you kill a man, and never mean t’, he’s just as dead,” Ygritte said stubbornly. Jon had never met anyone so stubborn, except maybe for his little sister Arya. Is she still my sister? he wondered. Was she ever?

And…

Jon turned to Alys Karstark. “My lady. Are you ready?”

“Yes. Oh, yes.”

“You’re not scared?” The girl smiled in a way that reminded Jon so much of his little sister that it almost broke his heart.

“Let him be scared of me.” The snowflakes were melting on her cheeks, but her hair was wrapped in a swirl of lace that Satin had found somewhere, and the snow had begun to collect there, giving her a frosty crown. Her cheeks were flushed and red, and her eyes sparkled.

“Winter’s lady.” Jon squeezed her hand.

6. Missing each other the most

He missed his true brothers: little Rickon, bright eyes shining as he begged for a sweet; Robb, his rival and best friend and constant companion; Bran, stubborn and curious, always wanting to follow and join in whatever Jon and Robb were doing. He missed the girls too, even Sansa, who never called him anything but “my half brother” since she was old enough to understand what bastard meant. And Arya … he missed her even more than Robb, skinny little thing that she was, all scraped knees and tangled hair and torn clothes, so fierce and willful. Arya never seemed to fit, no more than he had … yet she could always make Jon smile. He would give anything to be with her now, to muss up her hair once more and watch her make a face, to hear her finish a sentence with him.

…

As he rode, Jon peeled off his glove to air his burned fingers. Ugly things. He remembered suddenly how he used to muss Arya’s hair. His little stick of a sister. He wondered how she was faring. It made him a little sad to think that he might never muss her hair again. He began to flex his hand, opening and closing the fingers. If he let his sword hand stiffen and grow clumsy, it well might be the end of him, he knew. A man needed his sword beyond the Wall.

…

No one talked to Arya. She didn’t care. She liked it that way. She would have eaten her meals alone in her bedchamber if they let her. Sometimes they did, when Father had to dine with the king or some lord or the envoys from this place or that place. The rest of the time, they ate in his solar, just him and her and Sansa. That was when Arya missed her brothers most. She wanted to tease Bran and play with baby Rickon and have Robb smile at her. She wanted Jon to muss up her hair and call her “little sister” and finish her sentences with her. But all of them were gone. She had no one left but Sansa, and Sansa wouldn’t even talk to her unless Father made her.

…

She went back to the window, Needle in hand, and looked down into the courtyard below. If only she could climb like Bran, she thought; she would go out the window and down the tower, run away from this horrible place, away from Sansa and Septa Mordane and Prince Joffrey, from all of them. Steal some food from the kitchens, take Needle and her good boots and a warm cloak. She could find Nymeria in the wild woods below the Trident, and together they’d return to Winterfell, or run to Jon on the Wall. She found herself wishing that Jon was here with her now. Then maybe she wouldn’t feel so alone.

…

“I’m a girl,” Arya said, exasperated. If the old man was down from the Wall, he must have come by way of Winterfell. “Do you know my brothers?” she asked excitedly. “Robb and Bran are at Winterfell, and Jon’s on the Wall. Jon Snow, he’s in the Night’s Watch too, you must know him, he has a direwolf, a white one with red eyes. Is Jon a ranger yet? I’m Arya Stark.” The old man in his smelly black clothes was looking at her oddly, but Arya could not seem to stop talking. “When you ride back to the Wall, would you bring Jon a letter if I wrote one?” She wished Jon were here right now. He’d believe her about the dungeons and the fat man with the forked beard and the wizard in the steel cap.

…

“My lady?” Ned said at last. “You have a baseborn brother … Jon Snow?”

“He’s with the Night’s Watch on the Wall.” Maybe I should go to the Wall instead of Riverrun. Jon wouldn’t care who I killed or whether I brushed my hair … “Jon looks like me, even though he’s bastard-born. He used to muss my hair and call me ‘little sister.’” Arya missed Jon most of all. Just saying his name made her sad. “How do you know about Jon?”

“He is my milk brother.”

5. Keeping her secret identity as Arya of House Stark in the House of Black and White: Needle was Jon Snow’s smile.

At the water’s edge she stopped, the silver fork in hand. It was real silver, solid through and through. It’s not my fork. It was Salty that he gave it to. She tossed it underhand, heard the soft plop as it sank below the water.

Her floppy hat went next, then the gloves. They were Salty’s too. She emptied her pouch into her palm; five silver stags, nine copper stars, some pennies and halfpennies and groats. She scattered them across the water. Next her boots. They made the loudest splashes. Her dagger followed, the one she’d gotten off the archer who had begged the Hound for mercy. Her swordbelt went into the canal. Her cloak, tunic, breeches, smallclothes, all of it. All but Needle.

She stood on the end of the dock, pale and goosefleshed and shivering in the fog. In her hand, Needle seemed to whisper to her. Stick them with the pointy end, it said, and, don’t tell Sansa! Mikken’s mark was on the blade. It’s just a sword. If she needed a sword, there were a hundred under the temple. Needle was too small to be a proper sword, it was hardly more than a toy. She’d been a stupid little girl when Jon had it made for her. “It’s just a sword,” she said, aloud this time …

… but it wasn’t.

Needle was Robb and Bran and Rickon, her mother and her father, even Sansa. Needle was Winterfell’s grey walls, and the laughter of its people. Needle was the summer snows, Old Nan’s stories, the heart tree with its red leaves and scary face, the warm earthy smell of the glass gardens, the sound of the north wind rattling the shutters of her room. Needle was Jon Snow’s smile. He used to mess my hair and call me “little sister,” she remembered, and suddenly there were tears in her eyes.

4. After breaking his Night’s Watch vows for her alone, Jon’s dying thought is of Arya: Stick them with the pointy end.

Jon fell to his knees. He found the dagger’s hilt and wrenched it free. In the cold night air the wound was smoking. “Ghost,” he whispered. Pain washed over him. Stick them with the pointy end. When the third dagger took him between the shoulder blades, he gave a grunt and fell face-first into the snow. He never felt the fourth knife. Only the cold …

3. I want my bride back… I want my bride back… I want my bride back…

Jon walked to the edge of the Wall and gazed down upon the killing ground where Mance Rayder’s host had died. He wondered where Mance was now. Did he ever find you, little sister? Or were you just a ploy he used so I would set him free?

It had been so long since he had last seen Arya. What would she look like now? Would he even know her? Arya Underfoot. Her face was always dirty. Would she still have that little sword he’d had Mikken forge for her? Stick them with the pointy end, he’d told her. Wisdom for her wedding night if half of what he heard of Ramsay Snow was true. Bring her home, Mance. I saved your son from Melisandre, and now I am about to save four thousand of your free folk. You owe me this one little girl.

…

Jon flexed the fingers of his sword hand. The Night’s Watch takes no part. He closed his fist and opened it again. What you propose is nothing less than treason. He thought of Robb, with snowflakes melting in his hair. Kill the boy and let the man be born. He thought of Bran, clambering up a tower wall, agile as a monkey. Of Rickon’s breathless laughter. Of Sansa, brushing out Lady’s coat and singing to herself. You know nothing, Jon Snow. He thought of Arya, her hair as tangled as a bird’s nest. I made him a warm cloak from the skins of the six whores who came with him to Winterfell … I want my bride back … I want my bride back … I want my bride back …

“I think we had best change the plan,” Jon Snow said.

2. What do you know of my heart priestess? What do you know of my sister?

“The heart is all that matters. Do not despair, Lord Snow. Despair is a weapon of the enemy, whose name may not be spoken. Your sister is not lost to you.”

“I have no sister.” The words were knives. What do you know of my heart, priestess? What do you know of my sister?

Melisandre seemed amused. “What is her name, this little sister that you do not have?”

“Arya.” His voice was hoarse. “My half-sister, truly…”

1. Needle!

“I have one more farewell to make,” Jon told him.

“Then I haven’t seen you,” Robb replied.

Jon left him standing there in the snow, surrounded by wagons and wolves and horses. It was a short walk to the armory. He picked up his package and took the covered bridge across to the Keep.

Arya was in her room, packing a polished ironwood chest that was bigger than she was. Nymeria was helping. Arya would only have to point, and the wolf would bound across the room, snatch up some wisp of silk in her jaws, and fetch it back. But when she smelled Ghost, she sat down on her haunches and yelped at them.

Arya glanced behind her, saw Jon, and jumped to her feet. She threw her skinny arms tight around his neck. “I was afraid you were gone,” she said, her breath catching in her throat. “They wouldn’t let me out to say good-bye.”

“What did you do now?” Jon was amused. Arya disentangled herself from him and made a face. “Nothing. I was all packed and everything.” She gestured at the huge chest, no more than a third full, and at the clothes that were scattered all over the room. “Septa Mordane says I have to do it all over. My things weren’t properly folded, she says. A proper southron lady doesn’t just throw her clothes inside her chest like old rags, she says.”

“Is that what you did, little sister?”

“Well, they’re going to get all messed up anyway,” she said. “Who cares how they’re folded?”

“Septa Mordane,” Jon told her. “I don’t think she’d like Nymeria helping, either.” The she-wolf regarded him silently with her dark golden eyes. “It’s just as well. I have something for you to take with you, and it has to be packed very carefully.”

Her face lit up. “A present?”

“You could call it that. Close the door.”

Wary but excited, Arya checked the hall. “Nymeria, here. Guard.” She left the wolf out there to warn of intruders and closed the door. By then Jon had pulled off the rags he’d wrapped it in. He held it out to her.

Arya’s eyes went wide. Dark eyes, like his. “A sword,” she said in a small, hushed breath.

The scabbard was soft grey leather, supple as sin. Jon drew out the blade slowly, so she could see the deep blue sheen of the steel. “This is no toy,” he told her. “Be careful you don’t cut yourself. The edges are sharp enough to shave with.”

“Girls don’t shave,” Arya said.

“Maybe they should. Have you ever seen the septa’s legs?”

She giggled at him. “It’s so skinny.”

“So are you,” Jon told her. “I had Mikken make this special. The bravos use swords like this in Pentos and Myr and the other Free Cities. It won’t hack a man’s head off, but it can poke him full of holes if you’re fast enough.”

“I can be fast,” Arya said.

“You’ll have to work at it every day.” He put the sword in her hands, showed her how to hold it, and stepped back. “How does it feel? Do you like the balance?”

“I think so,” Arya said.

“First lesson,” Jon said. “Stick them with the pointy end.”

Arya gave him a whap on the arm with the flat of her blade. The blow stung, but Jon found himself grinning like an idiot. “I know which end to use,” Arya said. A doubtful look crossed her face. “Septa Mordane will take it away from me.”

“Not if she doesn’t know you have it,” Jon said.

“Who will I practice with?”

“You’ll find someone,” Jon promised her. “King’s Landing is a true city, a thousand times the size of Winterfell. Until you find a partner, watch how they fight in the yard. Run, and ride, make yourself strong. And whatever you do …”

Arya knew what was coming next. They said it together. “… don’t … tell … Sansa!”

Jon messed up her hair. “I will miss you, little sister.”

Suddenly she looked like she was going to cry. “I wish you were coming with us.”

“Different roads sometimes lead to the same castle. Who knows?” He was feeling better now. He was not going to let himself be sad. “I better go. I’ll spend my first year on the Wall emptying chamber pots if I keep Uncle Ben waiting any longer.”

Arya ran to him for a last hug. “Put down the sword first,” Jon warned her, laughing.

She set it aside almost shyly and showered him with kisses.

When he turned back at the door, she was holding it again, trying it for balance. “I almost forgot,” he told her. “All the best swords have names.”

“Like Ice,” she said. She looked at the blade in her hand. “Does this have a name? Oh, tell me.”

“Can’t you guess?” Jon teased. “Your very favorite thing.”

Arya seemed puzzled at first. Then it came to her. She was that quick. They said it together:

“Needle!”

The memory of her laughter warmed him on the long ride north.

Bonus: Only her father had ever called her pretty. Him, and Jon Snow, sometimes.
