DISCLAIMER: I do not own Frozen or RotG or anything in between.

COLLAB: This is a collab with Kinnaaan, who used to be my beta, but now I'm now working on this fanfic with her!

NOTE: This is my first fanfic ever, and Kinnaaan's second fanfic. This is both of ours' first collab and first Frozen/RotG fanfic, crossover or otherwise.

ALSO: This is a rewritten version of One Night, which I had to take down because of... reasons.

"Elsa!"

The blonde glanced up from the dirty counter and came face-to-face with a very angry Anna.

"How long have you been in working here?!"

Elsa winced in reply. Did she have to be so demanding and loud?

Elsa glanced at the clock - 7:56 p.m.

"I've only been working for eight hours."

"Only eight hours?" Anna shrieked in astonishment.

"Yes," Elsa said slowly, covering her aching ears. "Is that surprising?"

The brunette huffed and raised an eyebrow. "You don't remember?"

"Remember what?" Elsa asked, without the slightest idea of what Anna was talking about.

"You agreed that you would go to the club with me at 7!" She screeched, raising her voice. Other costumers in the coffee shop turned around, wondering what all the commotion was about.

"Shhh!" Elsa hissed, leaping forward and covering Anna's mouth. If there was anything she hated, it was public humiliation.

"Keep your voice down!"

She removed her hand from of her sister's mouth. Glancing at her palm - which was now smeared with lipstick - she wiped the red substance on her apron.

"Why don't you ask Ariel to go with you? Doesn't she like to go to clubs, too?"

"Ariel's with her dad in Hawaii right now." Anna replied, huffing. "She said she had some family problems or something."

"What about Rapunzel?"

"She's with her parents taking care of their farm."

Elsa just rolled her icy blue eyes and glanced at the clock. 8:03.

"Fine, my shift just ended. I'll meet you at the car in a little bit."

Anna nodded and tossed her a dress and a pair of boots over the counter.

'I'm probably going to get fired for unprofessionalism,' Elsa muttered to herself. Anna then swiftly strode out of Elsa's workplace, still fuming.

Elsa, sighing, walked to the back of the store to take off her apron and hat.

'Another day in paradise. Not.'

She had been working full time at Starbucks to pay for her and her sister's college tuition after their parents had perished in a hit and run car crash. After removing her work clothing, Elsa folded a small piece of paper with a ten digit number on it and shoved into her purse.

She slipped on the outfit Anna gave her – a short baby-blue dress that went three inches past her bottom, paired with knee-high black leather boots.

'What was Anna thinking?' Elsa thought. She could care less about going to the clubs and the parties Anna dragged her to. All Elsa cared about was finishing college and working her job. Without Anna nagging her, she'd probably only get out of her dorm to either go to class, the dining hall, work.

She exited the back door, not wanting her customers to see her in her revealing outfit. As she walked to Anna's car, she could feel the eyes of pedestrians following her. 'God, people can be such weirdos.'

Quickly covering her face in shame and embarrassment, she half-ran to Anna's car, but that only seemed to make the dress rise higher and higher.

When she opened the passenger seat door to the cherry red Ferrari Anna had received form their recently deceased parents , Anna glanced up from her phone to look at her sister. Their parents had always liked Anna more than her. Anna was the baby born healthy. Elsa was born with a problem - when her mother was giving birth to her, her umbilical wrapped around her neck, giving her lung problems. It affected her still today. Anna's eyes widened in astonishment.

"Wow," she breathed. "You look cute."

Elsa looked down at her dress and pulled it down – only to make the neckline go even lower than it already was.

"God, why did you give me something this short?"

The corner of Anna's mouth pulled up slightly. "I'm getting you a man tonight."

Elsa rolled her eyes and sub-consciously braided her hair while Anna started the engine.

After ten minutes of driving in an uncomfortable silence, Elsa finally broke the silence. "A guy gave me his number today," she muttered, fidgeting. Anna immediately looked over at her sister and smirked.

"Was he cute? Was he nice? Are you gonna call him back?" she demanded, one question tumbling out after another.

"Woah, wait," Elsa said, raising her arms up, "one question at a time. And for god's sake, keep your eyes on the road."

Anna just sighed and focused on her driving again. "So are you or are you not going to call him back?"

Elsa sighed. "I don't know," she said, glancing out her passenger side window, "I don't think so. I'm just trying to focus on school and work. That's all."

Anna scoffed, her eyes drifting over to scrutinize Elsa again. "No fun."

Now it was Elsa's turn to stare at her sister. "And do you have anybody special that I should know about?"

Anna's eyes traveled quickly back onto the road; a habit Anna displayed whenever she was embarrassed or ashamed. "Well - no. I haven't met my one true love yet."

"Well, neither have I," Elsa said firmly, finalizing the matter.

The redhead only sighed as she swerved into the night club parking lot and took a spot right by the door; the car jerking harshly.

"W-Well, no need to sit here moping about nonexistent true loves; let's go inside!" She said eagerly. Elsa glanced at the crowded building which flashing lights – The Snuggly Duckling. Who names a club that?

He waited in the massive line that wrapped around the building. As Jack gazed throughout the line, he saw girls dressed in short skimpy outfits that showed so much cleavage it made him uncomfortable.

"And they call this fashion...?" Jack hissed to his roomate, Kristoff. He shrugged in reply.

After a long while, Hiccup leaned over the line to see that only a few more people would go before they were finally allowed into the club.

"Hey, Flynn," Jack muttered to the bouncer. He flashed him his ID, and motioned for Kristoff to do the same.

The bouncer - Flynn Rider, one of Jack's friends from high school - smirked at them, and gave them the 'go.'

As they entered, Jack scouted the inside of the club, which flashed with neon lights and dancing bodies. Drunk people were wandering outside, smoking cigarettes - leaning against the wall to just to keep their balance.

Kristoff swung his arm around Jack's shoulders, "C'mon!"

Jack sighed at him, and slowly followed the blonde into the club. He immediately coughed; it smelled like alcohol and smoke - and puke.

He already saw Kristoff jumping and dancing in the crowd of sweaty bodies, but as for Jack, he went to the bar to order a drink.

Elsa felt a little bit guilty for faking her age. She and Anna a minor - into the bar. But Flynn Rider, who was dating their cousin, had no problem allowing them inside. But she still felt like she was betraying her late parents' trust, even though she was twenty and was allowed to drink.

"Hey."

Elsa flinched and looked to the side to see a man in his late teens/early twenties staring at her. She glanced around to see of he was talking to someone else, but nobody was there.

"O-Oh, me?" She pointed at herself to emphasize her point.

He nodded.

"Oh, s-sorry, hi," she said quietly. He didn't look quite as drunk as the other people in the club, and she had to admit, he was good looking. He had nearly white hair, piercing blue eyes, and a chiseled body – traits that she doubted would look good on anybody else but him.

She smiled shyly at him. "U-Uh, so..." She racked her brain to find any conversation starters. For some reason, school popped into her mind.

"Well, w-what school or college do you go to?"

'Smooth, Elsa,' she hissed at herself. 'Start off a conversation sounding like a stalker.'

He didn't seem to mind, though. "Disneyworks University. What about y – "

"No way!" she exclaimed, jumping up from her seat and interrupting him mid-sentence. "My sister and I go there together!"

A wave of surprise washed over his face. "Oh, wow, really? Cool, what year?"

"Sophomore. You?"

He laughed; a beautiful melody resembling chiming bells or people caroling on Christmas Eve, and a laugh that people would want to keep listening to. "Same."

He smiled at her again, ceasing his laughter. "I forgot to ask what your name is." He held his hand out.

"I'm Jackson Overland Frost – but most people call me Jack," he said with a smile.

She took his hand shook it. "Elsa Wynters… It's nice to meet you, Jack."

The bartender came up to them and brought Elsa and Jack their martini and beer, respectively. Jack lifted his bottle and raised it towards the bartender, silently thanking him.

"So," he said, turning back to her. "I was wondering if I could have your number, by any chance?"

"Um..."

She took a sip of her bitter drink and tried not to scrunch up her face in disgust, and resigned to gazing up at the ceiling - which was illuminated by flashing lights - debating yes or no.

'Oh. Well, this is a bit too fast and creepy for my taste... But he seems like a genuinely nice guy...'

"I'm... going to withhold my answer for now." She saw his face fall, and immediately revised her next sentence. "B-But I'll get back to you later on that!" By now, she was completely red in the face.

He regained his smirk as fast as he had lost it. "It's fine. You were probably a little creeped out by that."

She nodded, still a little bit flustered. "D-Do you mind if we talk for a while? After that, I'll decide whether or not to take you up on that offer."

"Sure."

They talked and joked for what seemed like hours, and during that time Elsa learned that he was cocky, arrogant, but under that very loosely woven facade, he was genuinely nice, and he loved to joke around.

Elsa finally checked her phone for the time: 1:27 a.m. "Oh crap," she thought aloud.

"What? What is it?" he asked, worried he'd offended her. "Did I say something wrong?"

"No," she said shaking her head. "No, it's not you. I have to make sure my sister gets back to her dorm at 12." She jumped off her chair and went searching for Anna in the crowd of people, after saying a rushed goodbye to Jack.

She tried calling Anna's name over the large commotion, but there was no reply. As she walked into the crowd of drunk girls and dancing couples, she saw a swipe of ginger hair. Turning immediately, she finally spotted Anna jumping up and down to the beat of the music.

She grabbed Anna's wrist. " Anna we have to go now." Judging by her lazy eyes, her posture, and her balance, she was drunk. "Come on, Anna, lets go home."

And so they left the nightclub and drove back to their college - and, mind you, Elsa was the one driving.

'I never did manage to get his number,' Elsa mused to herself, a little bit disappointed.
