After re-watching F2 for like, the 10th time, my heart still melts whenever the Snow Sisters lullaby scene comes up. So it's a well-accepted headcanon that elsa is a close friend with insomnia, she doesn't share that often cause that's normal for her. But once she was severly insomniac and couldn't sleep for days and Anna for the 1st time in forever tried singing the song, and did the nose thingie, surprisingly it worked.

Happens between Frozen 1 and Frozen 2 ;)

"Are you okay?"

Elsa chuckled at her sister's worried voice. She was far from okay. The last three days had been very far from okay. She barely slept at night, and it was starting to get visible during her Queen meetings or when she visited the Arendelle village, where people asked for her help or advice. And it surely was the main reason why Anna was asking this question.

"You look exhausted."

Right on.

"I am." Simply said Elsa.

Anna put her tea cup down. "Oh… Queen duties are getting on your mind, uh?"

"Well, it's not only that…" Admitted Elsa, who indeed was getting stressed by her new royal duties now that the gates had opened. She rubbed her eyes. "I'm also insomniac. Chronic insomnia, since… Forever? I guess? As far that I can tell, basically."

Her younger sister looked devastated to learn that. She stayed silent for a moment, which was an easy way to know how shocked she was.

"Elsa… Why haven't you told me?"

"I…" Sighed the blonde. "I don't know. Excuse me. I just… It's difficult to talk about me now, you see? Since we spend time together again, and…"

"Yeah, sorry, I understand. You should take all the time you need."

The Queen sighed, looking down.

Anna wanted to change the topic, and to bring a solution, and she held her chin as she thought.

"Mama's lullabies worked really well to put us to sleep when we were worried or sad. I think I still know the lyrics of the one about the river."

Elsa's eyes widened.

"You… You remember?"

Anna looked pained by her question, though in a sad way. "Yes, why?"

"But… I thought… That night, Mother talked about magic. It was about a magical river. And I thought that Pabbie had erased all the memories of magic of your–"

"Only memories of your magic."

Elsa's heart felt like pinched. Was that good or bad news? And she couldn't help but think about that moment again, when they all had returned to the trolls, and Grand Pabbie said that he couldn't bring back Anna's memories.

It was a bittersweet evening that day. Elsa had cried for hours in guilt, but it also was fun and soft afterwards to tell about all their happy childhood moments to Anna, who was all ears to know about them from her elder's point of view.

Anna approached, seeing how Elsa was lost in her thoughts. She had purposely cut her to explain why she remembered their mother's lullaby, but here Elsa was diving into her thinking again.

"Hey." She said in a sweet voice.

Elsa lifted her eyes again, like she snapped out of a daydream, and it was obvious now that she hadn't slept in a long (too long) time.

"Come here." Smiled Anna. "Come, come!"

The blonde finally chuckled, touched by Anna's adorable gestures and tone. She was on the couch, tapping the cushion, and Elsa accepted to sit down next to her.

"What now?"

Anna laughed. She didn't know if it was emotion or tiredness that made Elsa clueless and have her make an adorable pout, but she gestured to get closer.

"Cuddle close…" The redhead started, then froze. "What was the thing she always said before singing lullabies? Cuddle close…"

"Scooch in." Smiled Elsa.

"Right!" Exclaimed Anna.

A blast of nostalgia hit her, and she melted in a smile with her sister at the memory.

Elsa did as asked, and came closer to Anna. The latter noticed more than ever how things had changed since the Great Thaw, several months before: they were getting more tactile, finally allowing each other to be close again. It allowed their complicity and giggles to come back, and she was having the best months of her life.

There was a silence as Anna bit her lip trying to remember the full melody, and once she did, she started to sing.

Elsa was taken aback by the beauty of it. She even stiffened - the younger felt it, but kept going with a smile - and turned her head a bit. She had heard Anna sing several times recently, but that was the most beautiful voice she had ever heard in a long while. Her eyes started to hurt as she cried, her breath shaking with emotion.

"Anna, it's…"

"Shh, shh. It's a bit rude to interrupt. Come on, just close your eyes."

The redhead started over from the beginning, with an even softer voice this time. It was barely perceptible, and the logs cracking in the fireplace almost were louder. To Elsa, it felt angelic.

A hand hovered her face, and the blonde was about to close her eyes but her reflexes were increased with her nervousness, and she shivered. She squinted as Anna's finger touched her nose.

"Anna…" She said with a voice in-between mock and tenderness. "I know what you're doing. But this won't work, we're not children anymore."

"Just trust me, okay? Trust the lullaby."

Elsa was too tired and touched by Anna's care to refuse. She stayed quiet, and closed her eyes. Soon she felt Anna's finger stroking her nose with a soft and strategically slow move. Elsa smiled with amusement, but soon her smile drifted off. As Anna's singing voice came to another verse, the blonde's head tilted on the side, and before her sister even knew it, she snored quietly.

Anna finished the verse and looked down, impressed.

"Wait, it actually worked?" She whispered, excited.

Elsa seemed to have the most peaceful sleep she ever had in months. No, realized Anna. In years.

On that thought, she held Elsa tighter, and put a kiss in her hair as the blonde was cuddled against her.

"Sleep well."
