"For As Long As I Live..."

Everything went according to plan. With the help of his friends, Frost managed to land a magical touch of light onto Elsa's chest. Now he just hopes his love is strong enough to ignite the light deep within this demonic Elsa, cleansing her of all her darkness. He feels confident that it is indeed more than strong enough.

After the near death encounter him and his friends faced against Dark Elsa, enough is enough. It is time to put an end to this nightmare.

Jack wraps his arms around Elsa before she can strike and flies off, taking her all the way to the farthest grey mountain of the Three Peaks. He releases her upon landing. She shoves him away and stumbles across her feet. She scratches away at her chest, gasping at the return of something familiar.

"Th-this feeling…feelings. You idiot! What have you done to me?"

"It's going to be okay, Elsa." He raised his hands, signaling her to try to calm down.

"No it is NOT!"

She shoots lethal blades of ice at him but her aim is off. "You think I'm bad? I was worse before!"

"No, no you weren't."

She shuts her eyes, trying to keep the light inside her from growing. "Emotions are a terrible thing…"

"They're also the most wonderful thing there is."

Elsa glowers over at him.

"Like what I feel for you…what we shared…"

She looks away in denial and unleashes a gust of snow. The Guardian spirals his staff in front of him, deflecting the blast.

Jack then blocks another weak attack from Elsa. "You're not trying as hard anymore."

"It's a bit difficult when there's a something burning in the pit of my stomach."

He dodges a sloppy attack. "Then stop fighting it."

She pants with her arms hung low, "Never! What I was turned into…I…I loved it."

"More than you loved me?"

He managed to stump her.

"Elsa…I understand why you did it…" He stabs his staff into the ground, leaving it behind as he approaches her. "It's so much easier not to feel a thing. You were scared-"

"I'm not scared of anything!"

"You were scared about us…" He keeps a sincere voice. "I'm sure you were scared about hurting Anna again too."

The Queen shakes her head in bitterness. "She…she and I can never…"

"You can never have a normal relationship with her, no, but who does? You're still sisters. There's nothing she wouldn't do for you. She would be standing right here too if she knew, trying to talk through to you."

She looks over at him.

"Do you really think she would want to see you like this?"

"It doesn't matter what she thinks!" She shoots out a series of wild winter attacks. "It doesn't matter what anyone thinks!"

Jack lunges from side to side, dodging them all.

"I'm not that perfect girl anymore!"

Elsa ceases her raging temper tantrum due to exhaustion. Jack ended up about a dozen feet away in front of her.

"You were never perfect, Elsa…that's what I liked about you. That's what made you perfect to me."

Too tired to try to fight him, Elsa simply scoffs off to the side. She can't stand to look at him right now.

"Look, I'm scared too…but I don't let it take me over…" He stops in place for Elsa is threatening to deliver another attack.

"Despite what I am, I've managed to find the world's greatest group of friends that anyone can ever have. And then I found someone special who I could get even closer with."

Elsa lowers her hands.

"You once told me you finally met someone who you could be yourself around, someone you never had to worry about hurting."

She shoots him an evil grin. "Looks like I broke that promise."

Jack bobs his head down. "Yeah…you did. But that wasn't going to stop me."

Aggravation returns to her voice. "Oh stop pretending to care. What do you have to worry about? You'll live on forever-"

"That doesn't make it any easier!"

She flinches at his spike in tone.

"I know what lies ahead for us just as much as you…we can never escape it. But don't you dare think for a moment that not a night goes by where I don't stay up late afraid! Afraid of the day that I lose you…"

His tone then drops to sadness. "But this…losing you like this…it's the worst…you have no idea how much it hurts to see you like this."

A howling blizzard starts to surround them like the swirling storm inside, mirroring the conflicting chaos within her soul. The dark wants to silence him! Her light wants to jump out into his embrace and never let go.

Ice shards erupt from the ground around Elsa as a form of defense. The crystallized spikes are pulsating dark, burgundy-red at the core.

"So if you're going to kill me now, then get it over with…because I can't keep doing this…I just can't…"

The blizzard picks up speed. They are right in the heart of the snowstorm.

She looks angry at him for even testing her, but she cannot bring herself to do it.

"I don't think you will though," noticing her hesitation, he cautiously inches toward her, "because I know you're not possessed. It's still you, only twisted up inside and confused. And I also know you won't do it because you care about me just as much as I care about you."

Elsa lowers her sharp crystallized defenses.

Still moving with caution, he slowly reaches his hand out to her. Her body wants to do the same, but the evil in her resists.

"I love you, Elsa."

Her eyes widen with emotion. The blizzard stops in place; snow frozen still in the cold, silent air. This is the first time Jack Frost has ever told her that he loves her.

"You are the most amazing, gifted, most beautiful woman I will ever be with." Jack makes it to her, placing his reached out hand on her cheek. "And I know that the love of my life is strong enough to break free and come back to me."

Looking up at him and his heart throbbing smile, her eyes start to frantically change between her demonic black and her normal blue. Her face as well, caught somewhere between an angry and in pain expression, reflecting her dark side, to a sincere and deeply sorry expression, reflecting her true self. This continues until she shuts her eyes in a loud scream.

Elsa pushes Jack away and falls to her knees. The light inside her is shining ever so brightly, purifying her soul of its darkness.

Jack is terrifyingly concerned. "Elsa?"

She strains her hands over her heart and lets out an even louder cry. Her body shoots out a beam of frozen blue energy into the sky, blasting away all the evil black and red off of her. The force shattered the frozen still blizzard around them as well.

A bright shock wave from the blast reaches everyone else far across the battlefield of the three peaks. Everyone's attention is on the beacon. Kitsune gazes upon the beaming light in disbelief. "Impossible…"

After the force of the blast passes, the beam of Elsa's pure energy calms back down onto her, revealing the Snow Queen in her signature ice blue dress and normal light blonde hair.

Jack worriedly takes a step forward to check on her, "Elsa?"

Eyes closed, knees to the ground, and body tired from the victory over evil, she falls over to the side.

"Elsa!" Jack rushes in to catch her. His love's head dangles in his arms, "Hey, hey, c'mon…"

Her braided tail became undone in the triumphant display. Now her hair is all straight and loose in what Jack considers to be a gorgeous mess. He brushes a few strands out of her beautiful face.

She makes a weak moan, and opens her no longer demonic eyes. He exclaims full of happiness and relief, "Elsa! You're back!" Oh how he has missed looking into those big blue eyes of hers.

Elsa has regained her humanity. She touches Jack's face, silently starting to cry. She cries for her immense, grateful love for him, but she also cries out of immediate guilt for all the awful pain she put him through. "I-I'm so sorry, Jack…"

He wipes away the tears spilling down her cheek. "Shh don't be…it's okay, it wasn't your fault. You're back now. Everything's going to be alright. I got you…"

Her thin fingers trace along his jawline. Jack holds her frail hand up, pressing it gently into his cheek. She looks up into his sparkling ice-blue, snowflake-like eyes. He whispers to her ever so lovingly, "For as long as I live, I will love you. For as long as I love you, I will never let you go."

A smile forms on her weary face. She cannot believe he still loves her so unconditionally after all the villainous acts she performed, and did so with an evil, sadistic smile.

Then her hand slides down to his chest and falls onto her side as she passes out.

Jack stands up, carrying Elsa in his arms. Smiling down at the love of his eternal life, he speaks softly with relief and happiness. "Let's get you out of here. Safe...and sound."
