(Here's the new chapter! Enjoy!)

Arianna ran her hand through Idunn's hair as Harold strapped Idunn to the gurney. Pressing her soft lips to Idunn's forehead, she gripped Idunn's hand.

"I love you." She whispered into her ear. "Keep fighting for me….please."

Idunn shifted in her sleep.

Violetta and Harold gently but rapidly steered the gurney towards the castle. The bouncing of the wheels against the cobblestones echoed in Arianna's ears.

But no-one heard the sound clearer than Little Elsa. Her wet hair was still dripping down onto her now soaked shoulders.

"Friend Idunn….?" She said in barely a whisper. She stood on the tips of her toes, looking at Idunn's still figure lying on the gurney.

"FRIEND IDUNN!" Elsa shrieked, her little legs racing after Idunn. "FRIEND IDUNN!"

"Elsa dear, slow down!" Her mother, Lina yelled. Lina tried to grab onto the back of her daughter's dress to make her stop.

Elsa sneezed, the salt water still in her nose. "FRIEND IDUNN!"

Arianna paused, the child's voice catching her attention. She felt a lump into her throat, her hand gently leaving Idunn's soft hand. She turned around to Elsa.

"Oh, child!" Arianna gasped. She picked up Elsa in her arms.

"Sister of Friend Idunn!" Elsa gasped out, out of breath from running.

"Where are they taking her?! She's not dead, is she?! I only just met her! I wanted to get her another lollipop and everything! It's all my fault for falling in!"

Wet tears ran down Elsa's soft face. "Please, Sister of Friend Idunn! Tell me she'll be okay!"

"My name is Arianna." Arianna said, wiping the tears from the young girl's face.

"She's going to be just fine. My sister is a fighter, and I know it. On the outside it looks like she's just lying on the bed, but inside she's fighting with everything she's got.

"I'll give her your regards." Arianna hugged the young girl tightly and gently stroked her ginger hair.

Elsa hugged the queen back. "Thank you. I hope she feels better soon. She's a great friend."

Arianna laughed. "I guess that's why you call her Friend Idunn."

"Yes!" Elsa agreed.

Rapid breaths were heard from behind the pair.

"Oh! Your Majesty! I'm so sorry! I hope Elsa wasn't bothering you. I'm so sorry that her falling in caused this!" Lina dropped into a low curtsey before the queen.

"No no, it's okay." Arianna reassured her. "She's been an absolute angel." She smiled down at Elsa.

Lina breathed a sigh of relief. "Thank you, Your Majesty."

"I used all my manners, Mum! I promise!" Elsa said.

Lina chuckled as Arianna handed Elsa back to her mother. It wasn't too difficult, since they were similar heights.

"I am so sorry, Your Majesty. I truly am. I know my daughter would never do this on purpose. I hope your sister is alright. She seems just as strong as you and I know she'll get through this."

The more Lina mentioned Idunn, the harder it was becoming for Arianna to hold back her tears. Her eyes began to sting as if she had poured lemon juice in them.

All she could think about was Idunn.

Idunn. Idunn. Idunn.

Images of her sister filled her head. Good memories, bad memories. Lina's words became a blurred as she zoned out. Her face paled.

Lina paused. "Your Majesty, are…are you alright?"

Arianna inhaled deeply. "Yes…yes…I must…I must go check on my sister." Arianna stammered.

Lina nodded as she curtsied again.

Arianna nodded and walked towards the castle. It was short walk, but to Arianna, it felt like miles. Rapunzel had left with Idunn, so Arianna was left alone with her thoughts.

Arianna soon reached the infirmary, once again breathing heavily and severely anxious. She once again squared her shoulders and entered the bed six cubicle.

Seeing her sister laying on the bed, she gasped audibly. All the equipment besides the chest tube had been re-attached to her younger sister.

She didn't know whose heart ached more, hers or her sister's.

"Idunn!" Arianna rushed over to her sister, cupping her sister's soft face in her shaking hands.

"Wake up! Idunn, wake up! Please! Wake UP!" Arianna begged, her eyes burning as tears streaming down her cheeks.

Footsteps were heard behind her.

"She won't wake up, don't try." Harold said, his voice for once, slightly more gently.

Arianna turned red in the face and clenched her fists. "SHUT UP!" She yelled back at him, shocking the medical staff at her unexpected behaviour.

"No…Your Majesty…please try to understand. It's because-"

"QUIET!" Arianna yelled back. "I'M NOT INTERESTED!"

"YOUR MAJESTY!" Violetta interjected. "She's been medically sedated."

"What?! What did she do! She would never do anything wrong!" Arianna protested. "DID YOU PUT MY SISTER IN A COMA WITHOUT MY PERMISSION?!"

"No. Not a coma. Not that type of thing. She needs to rest, and the sedation will last a few days. Her heart was under a tremendous amount of stress suffering that heart attack, and the sleep will help her heal."

"You should consider her very lucky for surviving, because I fear that if she was to have another one with the current damage on her heart…the chances of survival…..will unfortunately be slim." Harold replied.

Arianna paled, feeling sick to her stomach.

Harold cleared his throat. "But that's why I have sedated her. Please try to understand, Your Majesty."

Arianna inhaled, holding onto her sister. "I….understand."

Rapunzel moved closer to her mother, looking at her sympathetically. "She's gonna be okay, Mother. You said she's a fighter."

Arianna blinked. "Yes. You're right. She was born a month premature and fought to survive. She's always been my fighter."

Arianna turned back to the bed, watching her sister's chest steadily rise and fall as she inhaled and exhaled.

Arianna placed her hand on Idunn's chest and steadied her breathing, in sync with her sister's.

Arianna reached over the bed rail for Idunn's soft and limp finger. Even just the very warmth of her sister's finger was enough of a comfort for Arianna.

She kneeled down, the beeping from the machines echoing in her ears.

*Flashback, Forty-Five Years Ago*

Two-year-old Arianna ran her little hand worriedly down the closed infirmary doors. Her mother had only been inside for five hours, but to small Arianna, it felt like centuries.

Her father reached out to cuddle her.

"Soon, my dear Ari."

"Soon for what, Father?"

"It's a surprise. You'll see."

"IT'S A GIRL!" the midwife exclaimed from inside the infirmary.

Arianna tilted her head, a confused look on her face. "Well of course our dog is a girl! She hasn't got a thingy-"

"Ah ah, ah, we'll have none of that unqueenly talk, Princess Arianna." Her father interrupted, picking her up.

"We'll go see your new surprise, shall we?"

Arianna nodded. "Yes! Can you tell me what it is? A clue? Is it a new doll? A new playhouse? Chocolate?"

Her father chuckled. "No. No clues. You'll see." He carried her into the infirmary, where her mother lay on the sixth bed. She looked relieved, despite the beads of sweat still on her forehead.

"Mama!" Arianna exclaimed.

"My sweet Arianna! Come here! I want to show you your special surprise."

Expecting a new doll, Arianna jumped out of her father's arms and raced to her mother.

Arianna stood on her tiptoes and peered over the bed railing. Her mother leaned over to reveal a small baby in her arms.

"That's a strange looking doll!" Arianna exclaimed.

Freya, their mother, laughed. "That's your baby sister, Ari. Say hello to Idunn."

"She looks funny." Arianna said

"Arianna, that's not a very nice thing to say about your new sister. Would you like to hold her?"

"Oh yes!"

Freya gently gave Idunn to Arianna. Idunn's blue eyes met Arianna's green ones as she snuggled up to her sister.

Idunn's small hand wrapped around Arianna's index finger and she kept it there, holding onto it, which comforted the newborn.

Instantly, Arianna's shyness vanished. "Hi! I'm Arianna! I'm your sister and you're going to be my brand new best friend! We're going to play dolls together and princesses and queens and everything!"

In her excitement, Arianna still overheard the conversation between her mother and the doctor.

"As you know, Idunn was born a month premature, so she will have to fight to survive. But I am confident everything will be alright, Your Majesty."

"Of course you're going to be okay, Idunn." Arianna whispered to Idunn as she continued to hold tightly onto Arianna's finger.

"You'll always be my little fighter."
