Anna wasted no time in rushing to the castle's library as soon as the three got back to Arendelle. She had ignored the questioning, concerned looks on their faces but she hoped that her own expression said more than words.

The words of Ahtohallen replayed in her mind, she wouldn't let herself forget them, as Anna ran a hand along the spines of the books.

"The force of flowing water runs through you, Anna. Your body had spent so much time underwater that it is now completely saturated…"

Anna crossed the room with a flutter to her skirt, she paid no attention to the figures at the doorway.

"When your sister used her magic to awaken you, she ignited the magic in it's force… I'm sure you are aware of how water can act as a medium…"

She finally found the shelf she was looking for. It was lined with old books that had belonged to her father, many of which she remembers the stories as they were told to her.

"That is why you can hear your sister's voice. Her magic has connected you… but water connects all of us."

By the time Anna had found what she was searching for, the figures had moved to standing behind her.

"Anna?" Elsa spoke first as she watched her younger sister flip hurriedly through a book. When she gave no response she pressed further "Anna, what did you see? What does-" she tried to peek at the cover of the book as if it's subject would explain something Anna couldn't, "what does a book have to do with what you saw at Ahtohallen?"

"Water passes through us all at some point, and soon enough there will be nothing but your sister's magic left in you."

"So I'll be-"

"Frozen. Yes."

Anna ignored her sister as she trailed her fingers across the pages as she read:

"...The first morning after he marries another your heart will break, and you will become foam on the crest of the waves."

Elsa cast a worried expression to Kristoff who stood beside her in similar concern. He spoke then, "Anna, please tell us what you saw."

Anna's thoughts broke for a moment away from the book as she remembered how Kristoff had been wiping tears away from his eyes with his sleeve as he exited Ahtohallen. She was struck with that guilty feeling again.
"what will be left of me?"

"Your beautiful form, your graceful walk, and your expressive eyes…"

"What would happen to your world if it were without you for good?"

Anna had already seen the effect of her death on the world, the lives around her. She saw the pain in every vision that Ahtohallen showed her, every detail of grief on the faces of those she loved the most.

She knew that if she died again Elsa would return to a life of unfulfillment, Kristoff would retreat into himself and most likely into the mountains. Anna knew her sister would never marry, never bear her own children as Anna realised that stepping aside had perhaps always been her sister's plan. But where did that leave Arendelle? Without heirs to their throne, with no monarchical future.

"So what are you going to do about it?"

Anna finally stood up, snapping the book shut and crossing it across her chest. She faced Elsa and Kristoff.
They were almost thrown back by the ferocity in her eyes alone.

Elsa finally squinted at the book's title. "The Little Mermaid?"

The sharp knives cut her feet, but she did not feel it, for the pain in her heart was far greater…
