"Sisters Vs. Ice Ghost Runeard" Writer Anon here. I've slowly begun turning the idea into actual fic. For whoever's interested, here's the start, picking up immediately after Show Yourself:

>"Hi, I'm Olaf! And I like warm hugs!"
>"I love you, Olaf!"
>The sound of those voices sent Elsa reeling. It was as if she had been sent back through time to her own childhood. When things were good. Of course, it wasn't actually herself and her sister she was looking at. It was more like... an echo, a copy, made entirely of snow, far more detailed than any of the creatures Elsa had brought to life. As she looked around at the rest of the cave, she found more and more of these 'snow echoes' appearing around her, going through more and more of her past. There seemed to be no order to them, appearing completely at random.
>Sneezing out a small group of Snowgies as she attempted to celebrate Anna's birthday.
>The coronation ritual which resulted in her becoming Queen of Arendelle.
>Playing make believe with Anna as children.
>Creating Marshmallow to escort Anna and Kristoff out of her ice palace.
>"Anna!"
>Had she known what the voice was coming from, she would've never have looked. Unfortunately, she turned towards the source of the voice just as young Elsa's beam of magic collided with child Anna's face.
>Elsa shivered as the memories came flooding back. That was the night everything changed... She forced herself to move on through the room, spotting other echoed memories as she went.
>Her and Anna's argument at the coronation ball.
>Setting up Anna's birthday party with Kristoff.
>Her mother, Queen Iduna, singing a lullaby to her and Anna.
>Creating Olaf.
>"HERE I STAND, IN THE LIGHT OF DAY...!"
>'Oh, no,' Elsa thought, wincing at the sight of her former declaration of freedom. 'I really DO move my hips like that. I... I need to be more careful with that.' She chuckled softly as she watched 'herself' in disbelief for another moment before moving on.
