Kristoff was riding Sven past boiling, hot ships. Sven struggles over the uneven surface.
"Come on! Come on!" he said.
Suddenly, a mangled ship, risen by ice, capsizes over them. They give it all they've got as debris falls all around them and the mast shatters. They make it past just as the entire ship slams down and cracks the thick fire beneath their feet. The fire opened up. Sven bravely jumped over a gap. But it's too wide. He bucks Kristoff to safety, but lands in the freezing water and disappears below.
"Sven? Sven!"
At first there was nothing but the wind and the tumbling hot water. But suddenly, Sven surfaced and clawed his way to a floating ice chunk. He called out, signaling for Kristoff to go on.
"Good boy." he continued.
Elsa moved blindly across the fjord, her hands burnt over a hot red. She stumbles on, determined. But she's running out of time. She clutches her chest. The color in her eyes faded, the inevitable was coming.
Kristoff was lost in the fire, didn't know which way to turn. But then he heard a faint-
"Kristoff." Elsa said.
"Elsa...? Elsa!"
On the other side Anna was struggling through her own heat, but the fear was consuming her. A dark shadow approached. It was Hans.
"Anna. You can't run from this!" Hans said.
She backed away from him.
"Just take care of my sister, the Queen."
"Your sister? She returned from the mountain weak and hot. She said you burnt her heart."
"What? No." Anna said.
"I tried to save her, but it was too late. Her skin was hot. Her hair turned red..." he said.
Anna's face sunk as she realizes what she has done.
"Your sister is dead... because of you." he continued.
Anna dropped to her knees, emotionally broken. And with that, it started to cool down. The hear cooled down mid-air, hung suspended, trapped in grief. Citizens and dignitaries rush to the wall edge and look out to see... Elsa, barely able to move but now able to see across the fjords to...
"Kristoff." she whispered.
"Elsa." he said.
She pushed on towards Kristoff and he ran top speed towards her.
There was still a lot of fjord to cross, but Kristoff gave it all he's got. He's going to make it. But then, Elsa heard the sound of a sword being drawn from its scabbard. She turned and saw Hans, behind Anna, as he raised his sword over his head.
"Anna." Elsa said and looked back at Kristoff as he ran for her.
She gave him a longing look, but then turned away from him and then... Using all of her remaining strength, as Hans brought his sword down, Elsa threw herself in front of Anna.
"No!" she continued.
Then in that instant, Elsa froze to hot solid mettle. The sword hit her instead of Anna and the sword shattered completely. The force of it sent Hans flying back and knocked him out.
"Elsa!" Anna said then rushed to her and touches her sister's hot face.
"Oh, Elsa...no...no, please no."
Olaf walks up and sees Anna, mettle.
"Elsa?" Olaf said.
Then Anna hugged Elsa and cried.
Kristoff watched in shocked despair while Sven stepped up to his side. Citizens and dignitaries on the castle walls bowed their heads. All of Arendelle was joined in somber silence. But then, Elsa began to cool down.
Olaf looks up and gasps. Kristoff and Sven notice, light up. Anna bends her arm and embraces Elsa.
"Wha-? Elsa?"
Elsa opened her eyes and smiled at Anna, relieved.
"Oh, Anna."
They embraced.
"...You sacrificed yourself for me?" Anna said.
"...I love you." Elsa said weak.
Olaf realized what's happened. He's so excited about it, he lifts his head right off his body and exclaims-
"An act of true love will thaw a frozen heart and cool a hot heart." Olaf said.
"Love...will cool..." Anna started realizing what she had to do. "Love... Of course."
Anna looks at Elsa with confidence.
"Anna?" Elsa said.
"Love." Anna lifted her arms, and the ground shook and cracked.
The heat cooled down and rose high into the air. Beneath their feet the bow of a ship cooled down. The entire fjord melts and other boats right themselves. The villagers came out to see the cool returning. In one final wave, Anna drew all of the heat into a giant fire in the sky, then waved it away, leaving only a cool fall day.
"I knew you could do it." Elsa said.
"Hands down, this is the best day of my life." Olaf said smiling.
Kristoff saw Hans trying to get to his feet. Then he marched toward him, prepared for a fight. But Elsa put up a hand and stopped him.
"Uh. Uh. Uh. I'll handle this." she said and went over to Hans.
"Elsa? But she burnt your heart." Hans said confused.
"The only burnt heart around here is yours."
Then she turned away from him, proud of her words. But not yet satisfied, she turned back and punched him right in the face.
"Ah! Whoa, whoa, whoa!" Hans said as he fell overboard.
Elsa came over to Anna and hugged her. Over her shoulder, Kristoff met Elsa's eyes. She smiled brighter, happy.
It was a beautiful fall day. The mighty ships have been repaired and are sailing away. On one of the ships, Hans was thrown into a brig.
"I will return this scoundrel to his country. We shall see what his twelve big brothers think of his behavior." the French dignitary yo Kai.
"Arendelle thanks you, my Lord." Kai said.
Down on the dock, Arendelle guards lead the Duke and his two thugs to their ship.
"This is unacceptable. I am innocent. I'm a victim of fear. I've been traumatized. Ow! My neck hurts. Is there a doctor I could...No? And I demand to see the Queen!" the duke said.
Then Kai stepped down from the gangplank to the dock.
"I have a message from the Queen. Arendelle will henceforth and forever no longer do business of any sort with Weaseltown." Kai said reading the scroll.
"Weselton. It's Weselton!" Duke said while the guards ushered him and his thugs onto their ship.
Anna runs through the crowd, pulling a blindfolded Kristoff along behind her. She's so excited she can't stand it.
"Come on. Come on. Come on. Come on!" Elsa said then ran him right into a pole.
"Pole." Kristoff said.
"Oops. Sorry." she said.
Elsa skipped to the perfect spot and stopped.
"Okay. Okay. Here we are."
She took off the blindfold and Kristoff opened his eyes. Before him sat the most beautiful, supped-up sled. Then Sven posed in front of it - Vanna White-style.
"I owe you a sled." she said.
"Are you serious?" he said blown away.
"Yes. And it's the latest model.
"No. I can't accept this..."
"You have to. No returns. No exchanges. Queen's order. She named you the official Arendelle Ice Master and Deliverer." she said.
Then Sven showed off the Ice-Master-and-Deliverer medal like he's king of the bucks.
"What?" Kristoff asked not able to help but admire her enthusiasm.
"Sure it is. And it even has a cup holder... Do you like it?" Elsa said.
"Like it?" he started and swept her up high overhead and spun her around.
"I love it... I could kiss you!"
Then he dropped her, suddenly embarrassed.
"...I could. I mean I'd like to. I'd... may I? We me...I mean, may we? Wait, what?" he said confused.
She gave him a quick kiss on the cheek.
"We may."
He smiled and went for it.
Olaf was enjoying the fall. Then he sneezed his carrot nose off. Sven caught it between his teeth.
Olaf gasped as Sven sucks the whole carrot into his mouth causing it to be gone.
Olaf's face sunk in sadness when Sven spit the carrot back out and jammed it into Olaf's face where it belongs. It's completely covered in reindeer spit, but Olaf didn't mind. He hugged Sven happily.
The gates to the castle were wide open. In the courtyard, stood Anna.
"Are you ready?" she said smiling.
Everyone started cheering.
She stomped and created an ice rink while Anna made smores. Everyone had skates at the ready then hopped onto it and twirl about. Then Elsa froze the fountain in a beautiful design and added some snow flurries for atmosphere. Then Anna came slipping in and Elsa caught her with a smore for Elsa.
"I like the open gates." Elsa said.
"We are never closing them again." Anna said then waved her hand and put magical roller skates on Anna's boots.
"What? Oh, Elsa, they're beautiful, but you know I don't ska-" Anna said.
Anna grabbed Elsa's hands and pulled her along on the ice. Anna slips and slides, but laughs in delight. Sven goes slipping past. Kristoff runed after him.
"Look out. Reindeer coming through!" Kristoff said.
Olaf skated and helped Anna coach Elsa.
"That's it. Glide and pivot and glide and pivot." Olaf said.
We pull away slowly, into the sky. We arrive at a bird's-eye view to see that where the castle had crumbled has been repaired with a ice. All is right in Arendelle. back to sleep."
Elsa rolled onto her back and spreads all her weight on Elsa.
"I just can't. The sky's awake, so I'm awake, so we have to play."
"Go play by yourself." Anna said shoving Elsa off her bed.
When she got to floor she sighed in defeat. But then she got an idea. So she hoped back on Elsa's bed and lifts one of her eyes.
"Do you want to build a snowman and have a smore to go with it?"
Anna opened her eyes and smiled.
After Anna got out of bed Elsa put her snow boots on and pulled Elsa's hand.
"Come on, come on, come on, come on!" Elsa said excited.
Then they snuck into the ballroom and Elsa shut the door.
"Do the magic! Do the magic! Then I'll do mine!" Anna said.
Elsa laughed and then waved her hands together. Snowflakes suddenly busted forth and danced between her palms, forming a snowball. Then she threw the snowball high into the air and snow bursts out and flurries around the room.
Anna danced about, catching flakes in her palms and mouth.
"This is amazing!" she said.
"Watch this!" Elsa said and stomped her foot and a layer of ice suddenly coating the floor, forming a giant ice rink.
Then Anna slid off, laughing.
They rolled giant snowballs and built a snowman together. Elsa moved his stick arms around.
"Hi, I'm Olaf and I like warm hugs." she said goofy.
Anna jumps up and hugged him.
"I love you, Olaf.
Anna and Olaf started to dance. While Elsa propelled them across the ice floor with her magic.
Anna fearlessly jumped off a snow peak into mid air.
"Catch me!"
Elsa made another peak to catch Anna.
"Gotcha!" she said.
Anna kept jumping and Elsa kept casting magic until she slipped and melt some of the ice to catch herself.
But then she slipped on some ice she missed and accidentally stroke Elsa in the head while she fell. Elsa tumbled down a snow bank and landed unconscious.
"ELSA!" she shouted and started running to Elsa then she took her in her arms. A streak of Elsa's hair was struck turning red.
"MAMA! PAPA!" she shouted crying.
Then the door opened with frightening fire and ice spikes. They burst through the hot door. They gasped at the sight of the room.
"Anna, what have you done? This is getting out of hand!" Agust said.
"Elsa!" Igna said and she and Agust rush to Elsa and take her in their arms.
"It was an accident. I'm sorry, Elsa." Anna said.
"She's burning hot." Igna said feeling Elsa.
"I know where we have to go." Agust said.
Then he sifted through a shelf to find an ancient book inscribed with Old Norse runes. When he opened it he scrambled to a page with an ancient map.
Then carrying the girls, the Agust and Igna rode their horses out of the kingdom. Steam from Anna's hands, leaving a trail of fire behind them.
On their way there a sleepy Kristoff and reindeer travel alone through the dark woods. All of a sudden, the Agust and Igna raced by with the girls, leaving the wake of fire.
"Fire?" Kristoff said.
Then he rode his reindeer as they follow the trail of fire.
"Faster, Sven!"
When they got to the edge of a deep valley he got off of Sven then hid behind a rock and peek out. Down below, Agust holds a frightened Anna while Igna holds the still unconscious Elsa.
"Please, help. My daughter!" Agust said.
Suddenly, a bunch of rocks tumble down the valley toward them. Then the rocks stop at their feet. Then they unfold, revealing bright faces.
"Trolls...?" Kristoff said.
Then the rock in front of him wakes up.
"Shush. I'm trying to listen." Bulda said.
Then she grabbed Kristoff and Sven by hand and hoof and hugged them close. Sven licks her face and she eyes them both.
"Cuties. I'm gonna keep you." she said.
Back below, the crowd parts of a troll as old as the Earth came and approached arthritically, but determined. Grand Pabbie nodded respectfully to the king.
"Your Majesty." he said referring to Anna." Born with the powers or cursed?"
"Born. And they're both getting stronger. Elsa has ice powers herself."
Grand Pabbie motions for the Igna to bring Elsa to him. She did as told and he examines her.
"You are lucky it wasn't her heart. The heart is not so easily changed, but the head can be persuaded." Grand Pabbie said.
"Do what you must." Agust said.
"I recommend we remove all magic, even memories of magic to be safe... But don't worry, I'll leave the fun and she will remember her ice powers."
Grand Pabbie pulled out a glowing red energy from Elsa's head. They saw her memories floating right above her. Grand Pabbie changes all of her magical memories to ordinary memories - fire play indoors with the girls in their nightgowns changes to outdoors on the summer fjords with the girls in summer gear. He puts the ordinary memories back in her head.
"She will be okay."
"But she won't remember I have powers?" Anna said.
"It's for the best." Angus said.
"Listen to me, Anna, your power, like Elsa's will only grow." he started as he conducted the Northern Lights to show a silhouette of an adult Anna creating magical Flames.
"There is beauty in both of your magic... But also great danger."
The flames turned into sharp spikes.
"You must learn to control it."
In the Northern Lights display, the sharp spikes cause human figures to panic and attack Anna.
"Fear will be your enemy."
Anna gasped and buries her face in Agust's chest. He wrapped his arms around her protectively.
"No. We'll protect her. She can learn to control it, they both will. I'm sure.
The Arendelle castle gates shutting.
"Until then, we'll lock the gates. We'll reduce the staff. We will limit her contact with people and keep her powers hidden from everyone... including Elsa."
The castle shutters close while Elsa sat on her bed as Anna's furniture disappeared. Elsa rushed to the hall to see Anna shut the door to her new room.
Elsa watched confused and sad.
