A/N - I have a feeling this will be a few chapters hence why I've started a new book for it. I am still working on chapters for prompts :)
Inspired by Angelina38's prompt.
A few weeks since the separation.
She was sure this would work. There were no downsides to this plan, because Elsa would be by her side, Soon; everyone would realise that they deserved to play together. Sometime a few short weeks ago, everyone had their brains replaced. Anna was sure of it - because she was the only seeing sense. No matter how many times she was told, Anna refused to lose sight of her sister. They would be building a snowman together soon. It was up to her to make that happen.
This was the 10th plan Anna had initiated that week. It was less fleshed out than her other plots, but nevertheless it required some thinking and therefore met the requirements of a mission. Here's how it would play out; Anna would pass Elsa a note, asking her to play. She would make sure no adults were within proximity. (Which was rule #1 of all rescue efforts). She realised where her previous attempts had gone wrong, her handwriting had been so big that Elsa didn't have space left to write. Secondly, she never threw her pencil under the door. Maybe Elsa wanted to reply, but she had inadvertently silenced her - just as their parents had. If Elsa didn't want to come to the door, that was okay. This time, she would push the paper harder, increasing the distance it travels under the door and maybe reaching Elsa. Elsa would answer and she would free her from the prison that was her bedroom - if not at least for a few short minutes before her parents put her back.
The small strawberry blonde tiptoed down the hallway, watching for any prying eyes. Look both ways before you cross the street. It applied to hallways too - especially when Anna was on a bike.
Coast clear.
She scurried to the door, her hand landing on the doorknob about to twist it. Old habits die hard. She took a step back her heart sinking as she did so, and glanced down to the paper on which she had scrawled Elsa, please come out and play. Elsa couldn't turn this down, surely? Who could say no to Anna? To her knowledge, they were still best friends. The rest of the world just had trouble seeing it.
She kneeled down, the side of her rosy cheeks settling on the cold wood floor. She couldn't see Elsa. But these days, it was safe to assume she was in there. "Elsa? Come get this!" Anna whispered secretively. First, was the note. She swished it through the gap under the door. It had some flight, and seemed to settle a little midway from the middle of the bedroom. Now, the pencil. This proved to be much more difficult. It was slower, and was getting lodged against splinters of wood. What if Elsa was losing interest with each passing second? What if an adult came by? She had to hurry, every precious moment counted. It was just them, and their moment. Forcefully, Anna shoved the pencil with all her might. "Incoming!" She hissed, as the pen popped before shooting across the floor.
"Oh no." Anna mumbled. Face, meet door. She was squished up against the panels. The closest to Elsa she had got in a while. But she was well and truly stuck. How it happened, she had no clue. With the universe having fallen upside down recently, she settled on not questioning the physics. There was a more pressing matter at hand - quite literally. How would she get out? This would also be a terrible time for Elsa to decide to open the door.
"At least you can just hand me your reply, Elsa." She giggled, waving her hand, maybe Elsa was waving back? She wasn't saying anything. This is not the time for jokes. She shook off the goofiness and put back on her serious face. If she could just pull her arm free then the mission could continue as normal. She hadn't failed yet. "We could chat!" Anna suggested, filling the silence. She had got into the habit of not waiting by the door - she was encouraged not to. Both by her parents and Elsa herself. This was a golden opportunity. She had no choice but to stay, so it wasn't her fault.
Breathlessly tugging at her arm, Anna asked, "What.. have you.. been... doing?" She continued to try to wiggle free, trying to not let the silence sting her. - "Ouch" She hissed, flinching. - Instead, a shard of wood under the door did. It didn't go amiss, Elsa saw her jerk in response to the pain. A deer in the headlights, she battled with herself over whether to intervene. They would arrive soon, Anna was never left unattended for too long.
"My! Hand! Is! Cold!" Anna complained, the unexpected feeling gave her some momentum. She was about to push off the door to free her arm when her parents arrived.
Rumbled. In the worst way possible. Caught in the act.
She was panicking. Her mission had failed. Her arm was hurting. Elsa, wasn't responding. She was being ignored. Best friends, don't do that.
"Mama! My arm!" Anna pleaded, accepting defeat. Laying on the floor wasn't as comfortable as she first believed. Not when you don't intend to be there. "The circanation!" She cried, well and truly believing she cut her arm off its blood supply. It earned the smallest of smiles from Elsa. Dramatics had been Anna's forte and she had missed hearing it. It was also good to know that Anna had been spending her free time scouring through biology books. Mama and papa had her. Anna was safe. This would be solved. The room slowly dissolved of the cold temperatures as she felt her heart settle.
With some work, Iduna freed Anna. "I could have done it myself!" Anna said sternly, crossing her arms as she was lifted off the floor.
"Of course, you can do anything you can put your mind to." Iduna smiled warmly. Taking Anna into her arms and leading her away from the scene. It killed her, to be taking Anna away yet again from Elsa.
"But Elsa-" She whimpered, reaching out to the door with her uninjured arm. Grabbing at thin air, Anna watched as the door grew smaller. She would try again later.
"Lets go outside." She suggested. If anything could divert Anna from Elsa - just briefly - it would be climbing trees, an adventure. The duo continued babble down the hall. Elsa listened as much as she could, thinking of what she would say. Until it fell silent, it was just her and Agnarr.
"You can't let her keep doing that." Elsa mumbled. He stood stiffly in the room, poised and formal. "If I could just see her -"
"No Elsa." He said sharply.
"- but she keeps trying because she doesn't underst-" Gesturing to the note Anna wrote, she croaked, at any moment she would start sobbing. She couldn't do that. The room was growing colder once again.
"Elsa I said no." Taking back Anna's note, he headed towards the door, "You did the right thing. Interacting would only encourage her. She will learn, eventually." He praised. Well, what passed for as praise nowadays. "Remember, this is for both of you. It's for the best."
