Elsa went back again the next day. And the next. And the next. The door remained closed. Anna remained silent.

She tried all sorts of tricks to get Anna out.

She pleaded.

She cried.

She yelled.

She appealed to her better nature.

Finally, one day, she put her eye to the keyhole and said"Do you wanna build a snowman?"

Anna could barely contain herself.

"Do you wanna build a snowman, Come on, let's go and play..." sang Elsa.

"I cannot build a snowman,

I'm stuck here in my room,

I really wanted to go out and play,

but I have to stay

Don't go away..."

"Then open the door." said Elsa reasonably.

Silence. Elsa crept away, respecting her sister's privacy. It took all her willpower not to break down the door.

She returned the next day.

No answer. The door was blocked up with snow, though she didn't know it.

"Do you wanna build a snowman..."she sang.

" Or ride a bike around the halls." she suggested, ignoring the fact that it would be unprincesslike. Anna giggled.

"I think some company is overdue,

I've started talking to the portraits on the walls.

You used to be my best friend..." Elsa was too choked up to continue. She leaned against the door, weeping silently.

On the other side of the door, Anna was crying as well. The sisters were so close, but yet so far apart...

Over the next few months, Elsa slowly lost hope. She stopped knocking every time she passed the door. She was older now, and the time would come soon that she would have to bear the burden of the crown.

Queen Idunn and King Agdar left on a visit to the nearby settlement of Weselton, Arendelle's nearest trade partner.

"Do you have to go?" asked Elsa, anxious about being in charge for the first time.

"You'll be fine." assured Queen Idunn.

"See you in two weeks." was Anna's farewell to her parents. Little did they know, that those would be their last words spoken to each other.

The ship was caught in a sudden squall off the coast of Weselton. The ship capsized. All on board were lost, Including the royalty of Arendelle.

The black veil fell over the portrait of the king and queen. The news of their untimely demise had reached Arendelle.

Elsa wandered through the corridor, clad in black. She hesitated before knocking on Anna's door.

"Anna?

Please, I know you're in there,

Can't you come out to be seen

They say have courage, and I'm trying to,

I'm right out here for you,

Just let me in

We only have each other,

Its just you and me,

What re we gonna do?

Do you wanna build a snowman..."

To Elsa's surprise, A soft voice answered

"Yes, I know you're out there,

I hear you every day

I know it must be tough on you,

But what can I do?

I can't let you in...

We don't even have each other,

we're both alone

what are we gonna do...

Yes I wanna build a snowman..."
