Anna had already been sent up to bed, warm goodnight's and hugs exchanged between the five-year-old and her parents. Elsa didn't hug her, Elsa barely even said goodnight to her.

Anna really didn't understand what she'd done wrong, why Elsa didn't want to play with her anymore.

After seeing that the young princess was properly changed from her dress to more comfortable nightclothes, the maid had tucked her into soft blankets and pillows, staving off requests for just one more story before blowing out the lights.

Anna was curled up on the soft mattress of her bed, blankets pulled tight by little hands and cheek mushed up against her pillow.

It was just her and the dark now.

It had never been a scary thing before - but, then, Elsa had always been in the other part of the room. She'd been there, if Anna ever needed someone in the night...

Now, there was a door, and a lengthy hallway, and another door that separated them.

In the mind of a child, it wasn't fair.

No matter how many times she knocked on Elsa's door, all she'd get was a muffled "Go away, Anna!"

Anna jolted when a knock sounded at her door, her hopes skyrocketing at the chance that it was Elsa - Elsa at her door, Elsa wanting to be best buddies again, Elsa being her big sister...

"...Anna, sweetheart...Are you still awake?" came the soft, nearly hesitant voice of her father.

The little girl fell back into her pillow, disappointed. She curled back up into warm bed sheets, little button nose crinkling as she sniffed.

There was silence, the thin sliver of light from the hallway blotting out for a moment as her father pressed forward from the doorway and into Anna's room. A weight at the foot of her bed, a calming hand that always somehow managed to find her foot underneath thick blankets.

"Gerda tells me that you've been knocking on your sister's door for weeks now..."

"...Is Elsa mad at me?" Anna asked, her little voice wavering. It was impossible to hide how she was feeling around her father.

"Of course not, Anna, Elsa's just - going through a difficult time. You might not understand now, but being older comes with it's own set of problems...And your sister has more to deal with than most people. Just give her time. Things will get better, you'll see."

Anna rolled over, blue eyes locking on the darkened but still visible outline of her father. "'M not gonna stop knockin'."

Even through the darkness, Anna could see his smile.

"Good, that's...good. We would never ask you to stop, Anna. It may not seem like it, but Elsa needs to hear you outside her door. It helps, more than you could know, sweetheart."
