Elsa didn't really need blankets per se. After all, she was the embodiment of winter; cold was a part of her. A chill from the outside had never bothered her.
Elsa really liked blankets though. She liked how they represented sleep. She liked the perfect rectangle shape they had. She loved when a blanket was crisp and clean and folded just so across her bed. She liked how warm they were. The warm reminded her of Anna.
She started the first night in her new room with one blanket.
She ended it with no blankets.
Anna had banged on the door for hours screaming, "Elsa! Come back! It's time for bed, I can't sleep without you. Please come out this isn't your room." And Elsa had buried herself in her blanket and sobbed and sobbed and tried to block out the sound.
Long after the sun had gone down, Anna finally quieted. Elsa thought Papa had come to put her to bed, but when she sneaked over to the door to check she could see Anna's silhouette. And Anna was shivering.
Elsa didn't know what to do. She wasn't allowed to touch Anna, she knew that much. And if she tried to get out, Anna would wake up and touch her and then the ice would come out and it would hurt Anna and she'd be in trouble again and it had only been one day and-
Elsa was shivering now, but not from the cold. Something inside her felt wrong. She couldn't get her breathing to calm down; couldn't get the air into her lungs. And the ice felt like fire crawling through her veins. Her fingers tingled.
Elsa jumped back in the bed and wrapped her blanket around her again. It helped. She felt small, she felt invisible, and most importantly she felt like she couldn't hurt Anna from over here.
But then she pictured Anna alone in the hall shivering again.
She got up and shrugged the blanket off. The door creeeeeaked when she pushed it open, and Elsa froze, but Anna didn't wake up. She snapped the blanket into the air and let it drift down onto Anna's sleeping form. It landed perfectly and Elsa gave a sad smile. Now Anna wouldn't be cold. Anna wouldn't be cold because of her.
Elsa spent the night curled into herself. She awoke the next morning with a blanket of snow covering her instead of a blanket of wool. But at least Anna was warm.
A/N idk where this came from but it needed to get out. I might do a chapter two to add a line or two that got cut from this draft. on top of the 50 other things I need to write djalk;fdl. It'll get done.
