Authors Note: This is set in between Frozen 1 and 2! :)

It was a peaceful summer night in the kingdom of Arendelle. Under Queen Elsa's rule, everything seemed to be thriving.

It took Elsa awhile to adjust to being around everyone again, especially Anna. A huge amount of guilt still washed over her, since she was the reason Anna's childhood was lonely. Elsa was determined to make up for it.

Anna tells everyone about how Elsa takes "best big sister" to a whole new level. When Anna accidentally injures herself with her unfortunate clumsiness (which honestly, happens more than one would expect), Elsa doesn't hesitate to carry Anna to the infirmary, even if Elsa has to create something with her magic to aid her task.

Elsa also takes days off to devote to special time with Anna. Sometimes they'd go to her ice castle to visit Marshmallow, other times they'd have snowball fights or what Anna likes to call "chocolate parties."

It has almost been a year since Elsa's coronation. According to Anna, it's been the best year of her life— but sadly, she has been fighting her own battles that few know about.

"Noooo! Elsa!"

Elsa's eyes shoot open at the sound of her younger sister's shrieks coming from Anna's bedroom.

Because Anna's scream scared her awake, Elsa quickly melts whatever frost is currently covering her room. She runs down that hallway as fast as she can.

A sleepy Gerda and Kai ask if

something is wrong, which Elsa hurriedly replies, "Nightmare. She's fine. Thank you, both."

Elsa doesn't even knock as she throws open the door to see her sweet sister in a fetal position on the bed. "A-Anna," Elsa runs over to her and places a hand on Anna's cheek.

Her sister was still asleep. "Anna, wake up. It's just a dream," Elsa gently shakes Anna's shoulders.

"B-but it was real," Anna tiredly opens her eyes and starts to sob.

Elsa pulls her into her lap and holds her as Anna cries into Elsa's shoulder.

"What was it about?" Elsa asks calmly, rubbing circles on Anna's back.

Anna lets out another cry, "Mama and Papa..." Elsa frowns and holds her sister closer. "But it wasn't like my another dreams about them. This time it was different."

Elsa readjusts herself to look into Anna's eyes. "How so?" She asks with a tinge of nervousness in her voice.

Tears continue to flow quickly down Anna's face.

"You went with them."

As soon as the words left Anna's mouth, Elsa lets out a gasp. Her little sister hugs her again, Anna's breathing becoming heavier.

"I-I told them not to go. That you needed to stay here. I k-knew what was going to happen," Anna starts to hyperventilate.

"Breathe, Anna. Let's take some deep breaths together, okay?" Elsa's concern grows with every gasp of air Anna takes.

Anna, quivering with fear, slowly nods her head. "Breathe in," Elsa inhales slowly, "and out."

After a couple of minutes, Anna's breathing returns to almost normal.

"I'm right here, Anna. I won't leave you," Elsa kisses her sister's head.

"Elsa, please stay with me tonight. In here. I don't want to be all alone-"

"I love you," Elsa interrupts.

Anna's eye flicker with happiness. That happiness that Elsa has noticed since she has opened herself up to Anna. "I love you too, Elsa."

Elsa pulls back the covers and lets Anna get in first. She pats the bed and smiles at Elsa.

Snuggling her close, Elsa starts humming an old lullaby their mama used to sing to them. Anna lets out a contended sigh and wraps her arms around Elsa.

Then, Elsa uses an old trick she learned from her Mama. She gently strokes Anna's face from her forehead down to the tip of her nose.

Anna mumbles, "I know what... you're... doing," she yawns as sleep starts to overtake her.

"Sleep my darling safe and sound," Elsa sings now, changing the last lyric because Anna is on the brink of sleeping, "when all is lost, and all is found."
