Lyanna watches Jon from atop of the courtyard's parapet, her eyes crinkling with pride as she watches Jon best Theon Greyjoy at the dance of swords. Every victory Jon made resulted in him outgrowing the label of bastard. He was so much more than a bastard of Winterfell. Not even Catelyn saw him as such. Many were so shocked when the news came that Ned had brought back his bastard one day. In fact Cat had shown up at Winterfell by his side as he held the infant in his arms, for she was one of three that knew the truth about Jon Snow.
Heartache nibbles at her heart when she recalls fifteen years prior. She remembers her sister (y/n). The fever of her cheeks as she held her newborn son in her arms. But she wasn't faring well. Birth rendered her near lifeless, allowing her to slip slowly away into the Stranger's arms. It was only a matter of time. She refused to leave the Tower of Joy, understood her fate as well as her siblings and sister-in-law did. (y/n) had just been content with the fact that she'd birthed a healthy baby boy.
"Jon." Her watery eyes turn up to Lyanna. "His name is Jon."
***
After Rhaegar's closest friend. Jon Connington was the one to deliver the note to Winterfell, ensuring it fell into the safe hands of the young Warden of the North himself. He'd been instructed by his revered lady, Princess (y/n) Targaryen.
The name was a slap to the face. A year prior to the birth of her son, (y/n) had supposedly been kidnapped by Rhaegar Targaryen who was supposed to marry Elia Martell the following day. Both up and vanished without a trace. Lord Rickard Stark was beside himself with grief and agony that they stormed to the capital to demand answers from King Aerys himself. Lord Rickard and his heir Brandon accused the king of hiding the location of Rhaegar and (y/n), said that she was to be returned immediately and the prince punished. But Aerys didn't take kindly to the slander they were slewing against the crown. He had them executed.
Ensuing blood shed consumed the Seven Kingdoms. Rhaegar appeared only on the battlefield with his own men. They fought against not just the king, but Ned and his own allies which included Storm's End. No sign of (y/n) nearby.
After Robert Baratheon killed Rhaegar and the regicide of the Mad King by the young lion Jaime Lannister, there was still no clue as to where (y/n) could be.
Robert, though it was Jaime who slew the king, secured the Iron Throne for himself. That meant Lyanna would be queen as she was engaged to Robert. She refused.
When Ned implored her to marry Robert, she gave him the tongue lashing of the century but it did the job in shutting him up. He couldn't force Lyanna to do something she didn't want to. That lesson was learned in childhood. If she desired to stay in the North then she would stay. Slighted at first, it didn't take him long to choose another bride. Cersei Lannister. A beautiful couple. Lyanna was happy that Robert even seemed to be truly smitten with the golden haired girl. They couldn't keep their hands off of each other.
Or so she was told. She couldn't attend their lavish wedding, not when her sister was still out there somewhere.
Day and night she worked in searching for (y/n). Northmen scattered across the vast land took part in looking for her.
They'd nearly given up.
And then Jon Connington delivered a letter in (y/n)'s handwriting.
She and Rhaegar had eloped. Rhaegar couldn't marry Elia Martell, he didn't love her but there was absolutely no way that Aerys would let him marry (y/n) Stark. Even (y/n) had kept her love for him a secret from everyone in her family.
Getting married as soon as they could. They had a short honeymoon for the war started shortly after. Jon Connington was entrusted with (y/n)'s safety, and though he wanted to be with Rhaegar on the battlefield, he held (y/n) in high regard. He agreed without much hesitation.
Soon she discovered she was pregnant. The pregnancy wasn't going well for her. She was constantly sick and weak. She didn't have long.
In her note, (y/n) specifically wanted Lyanna, Ned and his new bride to come. Only them. They were not to tell anyone else. Cat was loathe to leave her own baby Robb but knew how important this was for Ned and his family so of course she agreed to go. Leaving Robb pained her.
Jon was but a week old by the time they arrived to the Tower of Joy. The Sword of the Morning himself stood guard at the tower's entrance.
The babe was healthy. The same couldn't be said of his mother.
She was gaunt, so gray. This wasn't the sister Ned and Lyanna grew up with. Her smile was still the same though, even if it was a little strained. To each of them she spoke to, having the other two wait.
All of them, including Jon Connington and Arthur Dayne were to take this secret to their graves.
(y/n) died two days later.

"I know that look."
Lyanna jolts at Ned's voice, ripped from her melancholic memories. She presses her lips together. Ned grew into a fine lord. A horde of children filled the halls of the castle. Among them was the boy they thought their bastard brother. "Sometimes I can't help but think about her when I see him. He has her big, sweet eyes."
Ned nods. "He does." He rests his forearms on the wooden rail and looks down into the courtyard where Jon swung his sword in the way that Arthur Dayne had shown him that morning. Off to the distance was Jon Connington watching with a close eye. Theon and Robb are trying it out as well.
Jon was thriving. No one caught on to the truth of him. Never even breaching the surface. Many asked who the mother was since Ned agreed to claim fathership over him.
Bittersweet for the siblings watching their nephew grow up without his real mother and father. It was better this way. (y/n) wanted her son to grow up in the north opposed to the death and discrimination he might receive from being raised in the capital. Not just that, but Robert Baratheon was now entirely against the entire Targaryen line. He was already trying to locate the missing Prince Viserys and Princess Daenerys with plans to execute them if they're ever found. Children. It was insane that his queen was supporting the king's search for them. His claim to the throne was in danger as long as there was even one Targaryen left alive. And unfortunately Jon was included.
That day his sister died, Ned swore to her that he would protect Jon with his life; even if that meant protecting him against his own friend he thought of as a brother. Lyanna, Ned and Cat had spent sleepless nights speaking about the possibility of Robert finding out about Jon. Their voices hushed, only the quiet flame in the fireplace bore witness to the secrets being discussed.
They would never allow the secret of Jon's parents to become public knowledge. (y/n) entrusted Jon's life to them and they would not disappoint her. They would defend the boy with their life and take his secret to the afterlife.
