1. Americans in Arendelle

Elsa opened the old brown doors of the gymnas - high school - of Arendelle with a sigh that could probably be heard on the other side of the fjord. It was late August and she hadn't slept at all last night. Today was the first day of her last year of high school and this fact brought along mixed feelings. She liked almost every aspect of the trivial student life: Home work, classes, student projects and hours spent behind a computer screen researching, her peers, the occasional parties with the occasional exciting rush of acting like everyone else... but then there was always one thing getting in the way. Elsa was not like everyone else. She really wasn't. Her sister neither. Elsa was heir to the throne of Norway. And everyone in the school, everyone in Arendelle and the entire county, was aware of it.

Elsa was early. She usually always was. She was never late. She would arrive at least 15 minutes before the bell would ring and she would either be chatting with class mates, the school staff, or preparing herself for the first lesson. She did what was expected of her to be respectable. She neither kept people at a distance nor came too close to them. Except for a select few: Her sister, Anna - a princess with a heart of gold and of almost only joyful energy, her only true friend, beautiful and determined Jasmine Al-Hamed, and her favourite teacher, Robert Callaghan.

When Elsa entered the main hall, she turned right through a corridor to the main office and opened the white door finding a few staff members with cups of coffee in their hand, looking up to see who came in so early.

"Good morning," Elsa smiled politely.

"Good morning, Elsa," the nearest woman, Gertrude said, smiling back at her. At Arendal Gymnas, it was not expected from either the staff nor the peers to call Elsa by any titles. It was her first wish when she enrolled here. She was happy it was the case - it eased the tension when someone approached her.

"It's a fine day today. Do you have any news for me?"

Elsa wasn't asking this question because she was royal. No, she was student president and this was the standard procedure for anyone in this position at Arendal Gymnas.

"No, it's your first day back. There's nothing going on today for you."

"Okay, just checking. Thank you," Elsa replied, stepping back and turning towards the door. She was about to finish her visit at the office saying "have a nice day" to Gertrude, but was interrupted when a young stranger bumped into her making the brown leather backpack in her arms fall to the ground. Her books were now scattered on the wooden floor and Elsa couldn't help but to let out a small sigh.

"Man, shit - I'm sorry, mrs," he stammered with a hoarse, american accent. He quickly fell down on his knees where Elsa was located to help collect her books.

"It's okay," Elsa replied dryly after hearing the word 'mrs.' She couldn't help herself though. "In Norway, we students don't call our teachers by their last name."

For the first time, the american looked up and observed her face. His jaw dropped. Elsa found it quite amusing and her lips curved up into a mischievous smile.

"Shit - you're a student. Sorry, I assumed... I guess - but you asked if there were any news - wow. I.. sorry," he babbled.

"It's okay," Elsa chuckled at him. "I'm student president. I get that a lot. Titles, I mean. Don't worry."

The black haired student gathered the remaining books and handed them to Elsa, who put them back into the backpack. She then smiled politely at him as both of them rose from the floor. He looked strangely young to be in high school. Fourteen, perhaps.

"Thank you."

"Well, it was really my fault, so..."

Elsa smiled with a nod again, now gesturing that she needed to leave, but the american didn't understand her polite body language. Instead, he cleared his throat and handed her his hand. She looked at him curiously. He had no idea who she was. She slowly and carefully took his hand.

"Hiro Hamada," he said as their hands shook. "New student, just in. From America."

"America? Really? That's interesting. What part of the U.S.?" Elsa asked, genuinely interested.

"San Fransokyo, California."

Elsa couldn't help but ask the question she was most curious about.

"I hope you don't find this offensive... but - how old are you? We start high school here when we're around 16."

"13," he shrugged. "I know it's young."

He is still a boy, Elsa thought.

"Well, Hiro-from-California. You must be very clever. It was nice bumping into you, but now I need to get going. If you would excuse me, I need to find my Robotics teacher."

Hiro stepped aside and smiled. "Robotics, really? That's funny. It was nice meeting you too. I'll see you around."

Elsa trotted to the door, but needed to stop when Hiro asked his final question.

"What's your name by the way?"

Elsa looked back at the curious student. His dark eyes were shining. She didn't know why, but she didn't want to give away her name to him. She thought that with the name her whole prominent identity followed. And right in front of her, there was a complete stranger who didn't know of any titles or royal families. But then the rational part of her brain concluded that the thought was stupid. He would find out soon enough.

"Elsa," she replied.

Arendal Gymnas was a nationally well-known high school for three reasons. Number one - Elsa and Anna attended the school. Number two - it was one of the oldest secondary schools in not only Norway, but also in Europe. It was largely known for the beautiful pillars and old corridors. The third reason - despite the age of the school, it was considered very modern concerning the teaching methods practiced as well as it's famous english immersion programme.

"Welcome back," Robert smiled from his lab desk with a large mug of coffee in his hand. His grey hair and relaxed smile always welcomed her. Elsa thought he was the best and most sincere teacher at Arendal Gymnas. From the first math class she had with him last year, she had found him terribly good at making complicated things seem like a piece of cake. So gradually over the last year, the questions she had asked him were no longer just about math, but they had become more personal and he was one of the very few people she trusted with almost everything. He was the reason she had chosen the extra robotics class with him this year - although she had no intention in pursuing something in that direction after school. He had a refreshing view on most things and although he clearly enjoyed the logic of the subjects he taught in, he acknowledged that the advice Elsa sought, was not something that always seemed rational.

"Thanks, you too," Elsa smiled back.

"How was your summer?"

"Rainy, grey, and honestly I didn't even see the sun," Elsa grinned and gestured with her hands if it would be okay for her to sit opposite him.

He rolled his eyes, but gestured for her to sit. "I meant - besides the fantastic Norwegian weather."

"Well.. it wasn't a total bore."

Had it been anyone elsa doing what Elsa had been doing over the summer, they would never return to school after vacation. She had been touring the country together with her uncle Haakon, the king, her sister, Anna, and some of their household staff. Many days had been spent at opening ceremonies, visits at museums, fancy balls, and tours of small villages. It wasn't that she didn't enjoy seeing new sides of the country, it was just that it all seemed fake somehow. It was the same drill everytime: Someone gave all three of them flowers, a huge crowd had shown up to look at them from at least 3 metres distance, and then someone important, a mayor perhaps, presented something to them. Elsa knew the royal family's part in this game far too well: The country was a constitutional monarchy, so the monarch had actually nothing to do politically. Their job was to represent the country and to draw attention to things that needed attention. If Elsa would claim that something was smart, many others would do the same. It was in fact quite an important job. Anna thoroughly enjoyed this kind of attention and saw the value in this role, Elsa did not. She yearned for a more active role in society, making a difference in her own way - having a say. Therefore the most treasured days during summer for her were the days spent back in Arendelle, where she was somewhat left by herself and with the time to do things she liked. She would spend hours with novels in the palace garden, discussing interesting things happening in politics with her advisor Kai, go for strolls in the fjeld - the mountains - with Anna, and finally sit and use her full imagination trying to design and draw strange structures, sculptures, and buildings. It was her hobby and a very needed spare time activity to make her thoughts wander away from duties.

Elsa cleared her throat shortly after a little silence. "Anyway, you didn't mention what you did this sum - ?"

The door into the room opened quickly and all Elsa could see was a huge brown box with batteries and two legs sticking out at the bottom. After hearing a sigh, a red and exhausted face with shaggy black hair soon appeared beside the box.

"Mr. Callaghan, sir... do you need all the batteries in this room or - oh. Hello."

Another American. The guy, who was rather tall and stared confused at her, looked strangely familiar somehow. In fact, she reminded him of...

"Tadashi, I told you - It's Robert here. We're not in the US anymore, and you're not a student to me at the moment."

Elsa stared intently at the guy. She could swear he looked almost exactly like the older version of the young american student from just before. Her stare was greeted with a weird glance back to Robert, who seemed to just realise that the two weren't acquainted. Robert cleared his throat.

"Sorry - yes, you two aren't familiar. Elsa, this is Tadashi - a summer semester student of mine. He needed some fresh air and he is my intern here for this year."

Tadashi - who looked no more than 22 - placed the box at the nearest table and walked with quick steps to the two others.

"Yeah, um... that's me."

He handed her his hand which she accepted curiously. "Hello, I'm Elsa."

His eyes widened at the mention of her name and he slowly shot a glance over at Elsa's robotics teacher. Robert nodded with a grin.

"I've heard a lot about you from him," Tadashi smiled shyly. Elsa's mood dropped. She hadn't thought Robert would be a person to brag about teaching royalties.

"Really?" Elsa tried, trying to sound profoundly surprised about what would come next. "What kind of things?"

Tadashi took off his hat and come his fingers through the shaggy hair.

"You're his favourite student. And you don't even want to study his subject next year. It tortures him," he smiled over to Robert.

Elsa grinned and also looked over to Robert with a thankful smile. Robert hadn't told - ?

"Yes," Robert nodded. "She's quite the puzzle."

"In fact, " Tadashi continued, putting his hat back on, "he told me you would be studying international relations next year. "

Robert chuckled. "Such a waste."

Elsa shrugged her shoulders. "We'll see, I don't know what will happen this year."

The door opened again and all three of them looked over to see a face only Elsa knew well: Jasmine. Elsa thought that Jasmine was the most beautiful girl at the school. Her brown skin, alluring big dark eyes, and very long thick black hair stood out, especially among pale Scandinavians. Her father had come to Arendelle as a big oil investor - and the north Sea was full of oil. She didn't speak a word of Norwegian and therefore she had started at Arendal Gymnas.

"Do you mind if I borrow Elsa for a sec, Robert?"

When the bell rang in the afternoon, Elsa smiled to herself. First day back, and things had run pretty smoothly. But things were not quite as last year.

It was peculiar; the American she had met earlier today - Hiro - had been in two of her classes: Robotics and Norwegian. So he was a senior, despite his extremely young age. Whether or not he was aware of her 'official status' was very unclear to her: In both classes, he would greet her friendly as though they were old acquaintances (in this way she thought he was still unaware of her status.) On the other hand, he would shoot a few strange glances from time to time. As this tendency accumulated in Norwegian class, she assumed he was terribly bored - he couldn't understand a thing. But did he know? Another thing was Robert's intern. The two americans looked so alike. She hadn't seen Tadashi he rest of the day, so she difficulties trying to put two and two together. But they had to be related.

Another strange thing happened today. Hans. Elsa's longtime admirer - or as Elsa would call it: Arrogant pursuer - did not say hi to her once. She had seen him a couple of times during the day, and he had most unusually not made an effort to sweet talk with her. It was a relief, and she hoped that he had changed. Hans was the sort of guy who longed to be seen and admired in the public - for all the wrong reasons. Anna was always complaining that Elsa was being too rude with him. That concerned Elsa. She didn't want Anna to sympathize with him. At least he had always kept a distance to her younger sibling.

Anna was at her second year of high school and very popular among the other students. Where Elsa tried to be active with the school by running the student council, Anna was sociable in many other ways. She didn't exactly follow the same guidelines to be respectable as Elsa did. But why should she? She's not the one to inherit. Anna had many friends and was often busy trying to please everyone and follow the news and gossip of the school - but both sisters would always find the time and meet at some point in every lunch break. Of course, the same thing happened today. It was always Anna who insisted they should meet up for at least 5 or 10 minutes during the school day. She was very persistent about that - and Elsa loved that about her.

Elsa walked to the corner of a side street next to the school. She was waiting for their driver to come and for Anna to come. It only took a few minuted before Anna showed up, her eyes blinking with happiness.

"You'll never guess who tried to flirt with me today," Anna jumped.

Elsa rolled her eyes, but smiled. "Everyone?"

"No, you silly. H-"

"Wait a minute," Elsa stopped her, having spotted something in the corner of her eyes.

"What?" Anna asked.

"That's the 13-year-old American student who walked into me this morning, Anna. I told you about him at lunch."

Hiro walked about five houses away next to a figure that she was almost certain was Tadashi. So they are related.

"Really? Who's the tall, handsome guy next to him?"

"An intern helping Robert. I met him this morning. He seems nice."

When Elsa glanced down at Anna, she had to sigh. Anna had a dangerous smile on her face.

"Anna, he's kind of a teacher..."

"Oh, so what -?"

"Anna! Stop it."

-.-.-.-

Hello. Thanks for tuning in. Are you ready for some forbidden romance?

As you might have guessed, this is a crossover of BH6 and Frozen. What's important to note is that it takes places in the kind of futuristic time of BH6, however this story is centered in Arendelle and takes place during Hiro's year of graduation. (1-2 years earlier than the BH6 movie.) It will of course be explained what our favourite siblings from San Fransokyo are doing in Arendelle. And don't worry, Aunt Cass is there too.
