As soon as Elsa asked her sister that question, Jack's eyes widened in horror. He glanced over at Anna, thankful for her confused look, before redirecting his sights on the queen.

"Don't tell her!" he begged, causing the blonde girl to jump in surprise. She opened her mouth to respond, but he waved his hands in protest. "The less people who know about me, the better!"

It was true - Jack had seen plenty of movies showing how devastating it could be to meddle with time. And sure, those movies were considered science fiction, but so was he and the rest of the guardians, so he felt his reasoning was justified.

"Jack Frost?" Anna finally spoke, tilting her head to the side and giving her sister a stern look. "Is this some kind of joke, Elsa? Payback for the time I - "

"Shut up, Anna!" her sister squealed as her face turned red. She gave Jack another questioning glance.

He grasped his hands in front of him, silently pleading for her to drop it.

The Queen took a deep breath, closing her eyes and attempting to sort everything out in her head. When she reopened them, she was met with bewildered looks from Jack and her sister. "No, Anna, it's just a question," she sighed, avoiding eye contact with either of them. "A stupid one, really," she added under her breath.

Anna nodded her head, causing her braid to become even looser. "O-okay? Well, Anton said you had wanted to see me?"

Elsa snapped her attention back to her sister, her poise and elegance returning immediately. "Yes; Kristoff's... pet," she began tentatively, not wanting to offend her sister.

"Sven?" Anna supplied, crossing her arms haughtily.

The Queen nodded in acknowledgement. "Yes, that one. Will he be at the ceremony?"

Hearing this, the Guardian of Fun's blue eyes lit up in excitement. "Oooh, a ceremony?" he repeated, bounding over closer to the blonde. "Like, a party?"

"Sort of," Elsa responded, before her and Jack's eyes widened in realization.

"What?" the princess questioned quizzically.

Elsa gave Jack a fleeting glance, but he only shrugged sheepishly. He had forgotten how crazy believing in him could make people look.

The Queen rolled her eyes at his incompetence, before clearing her throat dramatically. "Sorry, my throat was feeling a little hoarse."

Anna gave her sister a skeptical look. "Right... and to answer your question: yes, Sven will be attending - he is the best man, after all."

Elsa scoffed in shock while Jack "awe'd" in understanding. A wedding! he laughed in his head, before a peculiar thought entered his mind. Who's wedding? ...Elsa's? he wondered, sparing her a fleeting glance.

He noticed she looked somewhat apalled, and wondered if this was about to become a candid Bridezilla moment - if she were, in fact, the bride.

"I'm to be in a wedding party with a reindeer?" the Queen shrieked.

Jack sighed in relief, although he wasn't quite sure what he was relieved about. If she was gonna get married, there's no way she'd help me get back - she'd be too preoccupied! he reasoned to himself. He quickly shook his head, ridding himself of his thoughts and focusing on the royalty in the room.

The princess nodded sheepishly, uncrossing her arms and smoothing down her dress nervously. "And Olaf..." she mumbled with a small smile.

"And a snowman?"

Anna rolled her eyes affectionately at her sister. "Don't act so surprised, Elsa. You all are our closest friends!"

Elsa allowed a small smile to grace her lips as she let her sister's words sink in. "Very well," she agreed hesitantly, preparing herself for what was to come.

The princess beamed as she practically flew across the room and scooped her older sister into a fierce hug. "Thanks, Elsa," she squealed before releasing her.

The blonde's smile grew as she gazed upon the utter joy in her sister's eyes. "You're welcome, Anna," she quietly laughed.

Suddenly, a playful look consumed Anna's face as she gave Elsa a suggestive look. "You should invite your 'Jack Frost'," she teased. "He sounds like he'd be the perfect date for you."

Immediately Jack's fair complexion turned a bright red color as he quickly looked away from the two. Elsa could also feel herself blush intensely at her sister's words. She attempted to laugh along with the princess, but even she could tell it sounded forced. Anna gave her sister a concerned look, fearing she may have crossed a line.

"I'm only joking, Elsa," she insisted, setting her hand on the queen's shoulder. "You're absolutely beautiful - you'd have no problem finding a real date, if you wanted."

At this, Jack let out a defensive "Hey!", gaining a skeptical look from the blonde. Grinning sheepishly, he ran his hand through his hair. "J-just saying; I mean, I am right here..." he laughed awkwardly.

Elsa rolled her eyes at her sister and the white-haired boy. "Don't you have some wedding planning to attend to?"

Instantly the princess straightened, a look of realization on her face. "Right!" she exclaimed before running ungracefully out the room.

Elsa sighed affectionately - her sister always was quite the character.

"Sooooo..."

The blonde girl jumped, again, and gave the pale boy a wide-eyed look.

Jack smirked at her reaction, before leaning against the door frame, feigning boredom. "A wedding sounds really fun and all, but I'm gonna have to pass," he teased, watching as a light shade of pink dusted the queen's cheeks. "I kinda need to find my way back."

Elsa forced a look of indifference as she regarded the strange man. "May I ask, back to where?"

Her seemingly invisible guest groaned in slight frustration. He wasn't sure how to explain the concept of time travel to someone from this day and age. But when he glanced back at her, he realized she was probably his best bet at finding someone who would believe him - especially since she already believed in him.

"The, uh..." he began with an innocent smile. "The future."

Elsa stared at him blankly - it was clear that if she wasn't insane, he had to have been. "Back to the future?"

Jack grinned cheekily. "Great movie - Michael J Fox is terrific."

The blonde arched a brow in confusion. "Movie?" she repeated slowly, unfamiliar with that word. "And what about foxes?"

The Guardian of Fun sighed in defeat. "Nevermind - do you have a clock?" he asked instead, getting back to the situation at hand.

"Made of ice?" Elsa guessed as she stepped into her room and sat on the foot of her bed.

Jack nodded eagerly as he did the same. "Yeah, a clock made of ice."

He watched as the queen waved her hand around, her powers swirling in front of her, creating a clock identical to the one in Father Time's home. His eyes widened as it landed gently in her lap. "I do now," she replied with shy smile.

Jack beamed at the blonde girl. "Awesome," he whispered, setting his sights back on the frozen masterpiece.

Elsa stared at it curiously, unsure of how this was suppose to help him. "So, you want it?" she asked, lifting it towards him.

He nodded absent-mindedly as he watched the snowflake pendulum swing back and forth. He slowly reached for it, anticipating the swirl of snow and the dizzying experience ahead. Right before his finger tips touched it, he looked up, locking his ice blue eyes with Elsa's.

"Thank you," he whispered, feeling a little bittersweet at realization that he wouldn't get to see this girl again, even though he didn't really know her.

She smiled in response, still completely baffled at how a clock she had made not ten seconds ago was going to send this strange boy home - sure, she could make living snowmen and fully functioning articles of clothing, but sending the Winter Spirit into the future with a clock? She wasn't crazy enough to believe that.

Jack smiled back as he closed his eyes and lightly brushed his fingertips over the little crystal snowflake.

Chapter four! I hope you enjoyed it!

Again, I own nothing!
