Lars was still in a state of shock, stunned by the realization that his crossbow was ineffective against the dragon. As Sven continued on course carrying Lars forward, the dragon suddenly spit a ball of fire at them, which the reindeer narrowly managed to dodge. The impact of the flaming projectile left a large crater in the snow behind them.
The near miss shook Lars from his stupor as the dragon took a step in his direction. Lars realized the dragon was now coming after him, and if that was the case, he had a chance to lure it away. Leading the dragon toward the village where it could do more damage and hurt more people was out of the question, so Lars took the only other option and steered Sven in the opposite direction: out onto the ice of the frozen harbor.
As the dragon turned away to begin pursuing Lars, it deliberately whacked the unsuspecting Elsa with its long tail, knocking the wind out of her and sending her flying back towards the village. Elsa came down roughly and tumbled through the snow, the deep powder cushioning her from a landing that otherwise would have left her seriously injured at best. Dazed and dizzy, Elsa drug herself out from under the snow, gasping to catch her breath.
Elsa looked up to see the dragon beginning to pursue Lars and Sven out onto the frozen fjord. She knew Lars was no match for the dragon, and she wasn't willing to let anyone else get hurt. She staggered to her feet with a renewed determination and ran towards the frozen harbor. As she stepped from the snow-covered ground to the ice without slowing down or breaking her stride, skates of ice materialized on the bottom of her boots, allowing her to transition seamlessly from running to skating. A frigid gust of wind suddenly came up at her back and quickly accelerated her forward toward the dragon.
With the help of her powers, Elsa was incredibly fast on the ice. She quickly caught up to the dragon, though she still had no idea how to stop it. Unaware of Elsa's presence, the dragon was still focused on its pursuit of Lars and Sven, gaining on them with every step as the ice cracked beneath the beast's enormous feet. The dragon took a deep breath, and Elsa realized that it was about to spit another fireball at the defenseless Lars and Sven. Mustering her powers, Elsa launched herself between the dragon and its quarry and, without stopping, produced a giant ball of ice just in time to counter the dragon's fire. The fireball collided with the ice in an explosion of water droplets that momentarily stunned the dragon.
As the shower of water droplets rained down upon him and Sven, Lars looked back into the mist and was surprised to see Elsa skating away from the dragon. She quickly came up alongside them.
"What are you doing?" Elsa shouted.
"Helping?" Lars offered.
"Are you sure?" Elsa replied. "You're supposed to get Anna to safety!"
"Only if something happens to you," Lars pointed out. "We're not there yet!"
"What if something happens to you?" Elsa asked.
"Don't worry," Lars replied. "I've got everything under control."
At that moment, the dragon recovered and spit another ball of fire in their direction. Sven and Lars dodged in one direction and Elsa dodged in the other. The fireball crashed into the frozen surface, leaving behind a gaping hole in the ice that the dragon effortlessly leaped over. Elsa skated back alongside Lars and Sven.
"See?" Lars said unconvincingly.
Even though Arendelle's army was already being outmatched by his own soldiers, Anton was anxious to join the battle himself, and was annoyed to find his way blocked yet again. Princess Anna's new ice-harvesting husband stood with his stolen sword at the ready, but Anton could sense uncertainty in the man's face.
"You again!" Anton said as he raised his sword. "You just don't know when to quit, do you?"
Without leaving time for a response, Anton charged toward Kristoff. Channeling his frustration, Anton swung his sword with all his might. Kristoff blocked Anton's attack, but the force of the blow pushed him back. Anton attacked again and Kristoff again blocked, but Anton didn't have the momentum he had before and Kristoff was able to hold his ground. Their swords locked together as they struggled against each other.
Suddenly, a small snowman seemingly came out of nowhere and leapt at Anton. Olaf had retrieved his arms and grabbed onto the hand in which Anton held his sword.
"Gotcha!" Olaf exclaimed.
"Let go!" Anton hissed.
"Nuh-uh!" Olaf replied, shaking his head.
Anton tried to shake the snowman off, but Olaf clutched tightly to Anton's arm. The distraction gave Kristoff an opportunity to break away and attack Anton. Even with Olaf's extra weight on his arm, Anton was still able to block Kristoff's attack. Undeterred, Kristoff attacked again, but Anton still easily defended himself even while struggling with the snowman.
In a more typical battle, Anton would have noticed if someone tried to sneak up on him and attack him from behind, but this was no ordinary battle, and Kristoff and Olaf were keeping Anton so distracted that he was unaware that Anna was behind him. Anna had lost her stolen sword in the snow, but she wasn't going to let that stop her. She charged toward the unsuspecting Anton and jumped onto his back.
Anton was momentarily confused as the sudden extra weight on his back took him by surprise, but as he felt Anna try to clamber up onto his shoulders, he realized she was going to try to take the helmet. Just as Anna tried to snatch the helmet off his head, Anton reached up with his free hand, grabbed onto the top of the helmet and held it tight against his scalp.
As Kristoff continued to attack, Olaf tried to pry Anton's fingers from the hilt of his sword to loosen his grip. Kristoff attacked again, almost knocking Anton's sword out of his hand. Angered, Anton attempted to advance on Kristoff, but the extra weight of Anna and Olaf made moving through the snow more difficult, and their struggling affected Anton's balance.
Anton tried to attack Kristoff, but as he stepped forward, he stumbled in the snow. Kristoff swung his own sword in defense of the attack, knocking Anton's sword out of his Olaf-loosened grip and sending it flying into the air. Anton lost his footing in the snow and fell forward. Kristoff turned to get out of the way but wasn't fast enough and Anton crashed into him, taking him down. Anna was still hanging onto Anton's back and ended up on top of both of them, while Olaf held tight to Anton's arm. Kristoff lost his grip on his own sword as he hit the ground, and it landed just out of reach; with the combined weight of Anton and Anna on top of him, Kristoff struggled in vain to reach it.
Out of reach ahead of them, the four dazed combatants saw Anton's sword land in the snow. The sword came down blade first, sticking in the snow with its hilt sticking up at an angle. A pair of scuffed black boots stepped up to the sword, and the four all looked up in unison to see who the boots belonged to.
It was Hans.
