Like so many times, Jack was letting the wind take him wherever it wanted. He was somewhere in the mountains. Just as he rounded a corner, he skidded to a halt. What was that? He stared up at a beautiful ice castle in front of him. He flew around it, stopping at a balcony.

"I wonder who lives here…" He said aloud, pushing the doors open.

He heard a voice drifting through the halls of the castle.

"Let it go, let it go…" Someone walked into the room he was standing in. It was a woman.

She was twirling on her feet, small bursts of ice coming out of her hands. "Can't hold it back anymore-" She stopped abruptly as she saw him.

Jack stared at her. He had only ever known one other person who had ice powers. But, surely Elsa was just a little girl with cute puffy cheeks and she was only half his size. This woman, she looked like a queen. She was gorgeous. Her dress was made purely of ice, with transparent sleeves, a slit at her right leg and a long cape. Her hair was in a messy French braid and it hung over her left shoulder.

But there was no mistaken. Not many people had cerulean eyes and ice powers.

"Elsa…?" He whispered.

She smirked. "Queen Elsa, actually. It's nice to see you too, Jack." She crossed her arms.

His face broke out into a grin. "Elsa! It's been ages! You're all grown up! And you're a queen? Wow, how time flies!" He chuckled. "So much has happened. I've become a guardian, Elsa! I am the winter guardian of fun" He grinned and played with a snowflake at his fingertips.

"You would love to meet my team! North and Bunny, Sandy and Tooth! We had to fight this one guy" He noticed how her expression changed when he said that. She looked worried and maybe slightly… angry?

"He is gone now, though." He said quickly, trying to reassure her. Her frown turned into a slight smirk. "Really?" She asked.

He was confused by her reaction. "People believe in me now, Elsa!" He said, trying to steer the conversation away from the fight.

Elsa smiled at his last words. "I'm happy for you Jack." Then she raised an eyebrow. "But I do recall someone promising to return."

Jacks smile faltered. "I was going to, I just… I'm so sorry! I guess I lost track of time, because of the whole guardian thing, and-"

"It's alright. I forgave you a long time ago." Elsa said. "It's been 17 years."

Jack looked shocked. "Years? 17?" He stuttered. Then something clicked. "You're 27?"

Elsa sighed. "Yeah. You missed quite a bit. My parents died when I was 18. Three years later, I froze my entire kingdom on my coronation, including my sister. I was able to thaw everything, but it wasn't easy." She said, shuddering as she recalled all those painful memories. Jack stared, stunned. Elsa gave him a half-smile. "Things got better after that. Anna and I became very close. She got married and she and Kristoff had twins. She is actually pregnant again." Elsa smiled. Anna would be driving Kristoff insane. She could just see it.

She brought her attention back to Jack. "I, uhm…" Elsa showed him her left hand. There was a silver ring with a blue and black diamond glittering on her ring finger. He gasped, making Elsa grin. "We met 6 years ago, about three months after my coronation. We got married 2 years later. We moved here, into our ice castle, after the wedding…"

Her words faded into the background as he stared at her ring. That black and blue diamond… he had a bad feeling about it. He wasn't sure what, but something didn't feel right. And somehow he felt out of place. He hadn't changed at all, whilst Elsa had moved on with her life. She was a Queen. And she was married!

"Jack! Are you listening?" Elsa asked him.

"Huh? Yeah, yeah…" He trailed off, trying to ignore the uneasy feeling inside of him.

Elsa smiled. He hadn't changed one bit. "Well, as I was saying, I have a daughter. He name is Katherine, or Katie. She is turning three next month." Right on cue, a little girl came bursting into the room.

"Momma!" She screamed, laughing. "Papa chasing me!" Elsa chuckled and picked her daughter up. She had a huge mop of curly black hair, the complete opposite of Elsa. And she was even paler than her mother. She was wearing a purple dress, also made of ice, and black slippers.

"And why is Papa chasing you?" Elsa asked her.

Katie pouted. "He said he tickle me if I don't eat vegetables!"

Elsa smiled. "Well, we can't have that now, can we?"

Jack was gaping at her. Elsa was a mother? She had a daughter? "Katie, will you say hello to our guest? His name is Jack Frost."

She looked up at him with piercing cobalt eyes. She waved energetically and said, "Hi! I like your hair!"

Elsa laughed softly, wiping some bit of food off her daughter's cheek. Jack managed to croak out a "Hi", still in shock.

Elsa glanced over at him. Just as she was about to say something, a man came walking into the room. Jack didn't know why, but he seemed familiar. He had slightly messy short black hair and he was very tall. He was wearing black pants and shoes and a white shrit that fitted him tightly. Jack couldn't decide if he had copper or silver eyes.

"Where is my little snowflake?" He said in a British accent. He walked toward his wife, not noticing Jack.

"Nooo!" Katie shrieked. "Momma! Papa don't tickle meee!"

The man laughed and scooped her into his arms. "You are too cute!" He said, kissing his daughters cheek. "Papa won't tickle you if you eat your vegetables, okay?" He reasoned with her.

"But, papa…" She mumbled into his shoulder.

He sighed. "You have to eat your vegetables to get beautiful and strong like your momma." He winked at Elsa, making her blush.

Katie nodded and waved her arms. Twirls of ice and black sand came out of her hands and formed a small, slightly deformed tiara on her head. "And then me be Queen?" She asked, pointing at her self-made crown.

He chuckled. "That's right, my princess."

Jack had become even paler than usual. No, he thought. This cannot be happening.

Elsa lightly touched her husband's shoulder. He looked at her, and Jack could see the love they shared. So it wasn't a trick. This was real.

"We have a guest." She said, pointing at Jack.

Pitch smiled and looked around, his eyes settling on Jack. He inhaled sharply. Elsa tensed. Pitch had told her about his battle with the guardians. But that was a different man. This man, here and now, was the man she loved. And he loved her. They had a family, they had a life together. They were happy.

Things had changed.

Pitch was no longer the nightmare King; He was the King of Arendelle.
