Ymke's POV- Ice palace

Ymke was able to hide Xenysis behind a nearby ice fountain in time so that Hans wouldn't notice them. She decided to follow him, so she picked Xenysis up, and flipped him onto her back. When she reached the top of the stairs, she saw Hans standing in the middle of a shattered chandelier. He checked the unconscious Dragonose and Elsa, then formed a portal of darkness. 'Wait, what?' Hans proceeded to drag Dragonose and Elsa through the portal, and watched it disappear.

Ymke: "Hans opened a portal to darkness?! Xenysis is the only one with a heart that I've seen control the darkness, and stay good."

Ymke snatched Xenysis's twin swords, then ran to the balcony. On the way, she passed by two unconscious Wesselton guards. She spread her fire-wings, and took off like a jet. A sphere of fire formed around them, and they sped even faster.

Xenysis's POV- Above Arendalle

For a long time, all he saw was darkness, and all he felt was cold. Recently, however, a new feeling washed over him: warmth. His head no longer felt freezing, but his heart was still 'cold as ice.' Xenysis opened his eyes to find himself on Ymke's back. She had his twin swords in her hands, and seemed to have wings. However, these wings were made of fire. Ymke slowed to a hover. The sphere of fire around them dissipated.

Ymke: "I see you're awake."

Xenysis, still dazed: "Yeah."

Ymke: "Can you still summon your keyblade?"

Xenysis tried to summon the Lover's Embrace, and was surprised to find a different keyblade appear before him. This keyblade seemed to be made of ice. The keychain link was an ice hexagon, with a snowflake embedded into it. The hilt was a similar hexagon, except that the snowflake was rotated slightly. The shaft was made of a carved stone, resembling the towers at Arendalle castle. The teeth was a snowflake as well. Xenysis decided to name this keyblade Eternal Winter.

Xenysis: "Well I can summon a keyblade, but just not mine."

Ymke, clearly confused: "What do you mean?"

Xenysis formed a platform of darkness in front of him, and hopped onto it. He showed the Eternal Winter to Ymke.

Ymke: "weird, it mus've been caused by your heart being frozen."

Xenysis: "My heart's frozen? Did Elsa cause it?!"

Ymke, defensively: "Yes, and yes. But Elsa didn't mean it!"

Xenysis slightly nodded. Then they slowly lowered themselves to the castle grounds, and followed the distinctive sound of footsteps. When they passed a group of dignitaries, they glared at Xenysis and Ymke. The duo noticed Hans leave a dark room, with pleading on the other side, and Hans locked the door. Xenysis and Ymke hid until Hans was out of sight, then they used their keyblades to unlock the door. The duo walked into the room, only to find Anna on the ground, all of her hair now snow-white. Her fire-crystal was missing.

Xenysis and Ymke: "Anna!"

As Xenysis brought her to a nearby fireplace, Ymke lit it with her powers. Xenysis has a feeling that he knows what happened.

Xenysis: "Where's Hans? What happened to your kiss?"

Anna: "I was wrong. It wasn't true love."

Ymke: "Well, then we'll just have to find another act of true love to save you! …Any ideas?"

Anna: "I don't even know what love is."

Xenysis: "That's okay. We do! Love, is putting someone else's needs before yours."

Ymke, to Xenysis: "Like when you saved me from getting my heart frozen?"

Xenysis, nodding: "Or when Kristoff left you with Hans, despite wanting to be with you forever."

Anna: "Kristoff, loves me?"

Xenysis, surprised: "wow, you really don't know what love is, do you?" Ymke smacks him in the back of the head. "Ow!"

Anna, giggling: "Looks like I'm not the only one with a true love."

At that, Ymke and Xenysis blushed, trying their best not to look at each other. Then, a strong wind blew open the window, knocking over the queen on a chessboard. Xenysis ran to the window, about to shut it again, when he noticed something in the distance. He formed a pair of binoculars made of darkness, and looked through them. He gasped.

Ymke, curious: "What is it?"

Xenysis, excited: "It's Kristoff and Sven! They're coming back this way!"

Anna, hopeful: "What?!"

Xenysis, whistling: "Wow, they're really moving fast." Sarcastically: "I guess I was wrong. I guess Kristoff doesn't love you enough to leave you behind."

Anna: "Ymke, help me up. I need to get to Kristoff."

Xenysis, handing Anna the fire crystal: "Here, you'll need this more than me."

Anna, shocked: "Thank you."

Xenysis and Ymke helped Anna up, and half-dragged her through the hallways. Behind them, Xenysis could see ice spike coming out of the floors, walls, and ceiling. In front of them, a wall of ice raised from the ground, trapping them. Ymke tried melting it, but failed.

Xenysis spotted a nearby window, and used the Eternal Winter to unlock it. He slammed his weight into it, and the window came off of it's hinges. Ymke half-melted the snowbank below to form an ice slide.

Ymke: "Slide, Anna!"

Xenysis, Anna, and Ymke slid down the slide, and made it to the ground. Xenysis and Ymke half-carried Anna towards the fjord, where Xenysis spotted Kristoff. 'Whatever happens, we need to get Anna over to Kristoff.' Xenysis glanced at his hands. The fingers were frostbitten, and the tips were pure ice. 'There's not much time left.'
