A/N: Hello, everyone! I have here a new Rivetra fic. By the way, I have decreased the character's ages to high school age, so Petra is about 16 years old, meaning that the characters Eren's age will be around 13 and 14 years old (but that doesn't mean that they won't have their deep character stories). Reincarnation AU

Anyway, I don't own Shingeki no Kyojin and all of that disclaimer stuff. Inspiration is from Naty17's The Girl in the Ward. Enjoy~

Chapter 1: First Night

"Patient name, Petra Ral. Age, 16 years old. Diagnosis, Lacunar amnesia. Cause is head trauma to the hippocampus. Witnesses report that the patient attempted to stop a fight at a party, but got hit in the head with an alcohol bottle of some sorts. Stayed in a coma for two weeks. Severity of memory loss proabably requires more tests to verify..." The doctor droned on a list of injuries and diagnoses that seemed to trail on for eternity.

Petra Ral could barely keep her eyes open, much less concentrate on the string of information that she had to listen continuously during her one month stay at Lady Maria hospital. Today would be the day she transfers to Saint Rose Psychiatric Hospital for Children, where she would go through more intensive therapy to recover memories she wouldn't even recall experiencing. She wondered what she could have forgotten, and how many important memories she had lost.

"...Possibilities include traumatic amnesia, source amnesia, partial retrograde amnesia, and severe anxiety. Currently in a stable condition to have a roommate. She will spend the rest of her recovery time here with you." he finally finished.

"Thank you, Doctor Harrison," the female receptionist replied. She was dressed in black business attire and wore her dark hair in a bun, a grim expression on her face. Just like a funeral, Petra thought. It's like they're preparing for my death. She tried to brush off the thought. She was all right. Her head injuries weren't going to be the end of her. Hopefully.

"Please come this way, Miss Ral." The voice of the receptionist interrupted her train of morbid thought. The two walked along the corridor of the hospital, with a nurse trailing behind to keep watch.

The ward was different from what Petra imagined. She had pictured bleak white walls, hundreds of forgotten patients crammed in rooms left with no one to care for them, and sinister nurses who reveled in the suffering of the patients.

Instead, she saw sandy honey colored walls, simple decor that gave the building a cozy atmosphere (she noticed that none of the decor had any glass or any other material one could potentially stab another with), and pictures strewn randomly on the walls, probably drawn by the patients judging from the broad spectrum of skill each one of them showed. The young nurse, although appearing slightly nervous, did not seem particularly evil, and so far she had not come across anything that looked like a torture chamber. They continued walking, an awkward silence hanging over the three women, the only sound being the clicking of the receptionist's high heels. After several turns, they finally came to a stop, revealing a cream colored door with a metal plating that had the number 057 in black paint.

"This will be your room, Miss Ral," the receptionist informed. "Your nurse will help you from here on." She turned around, the click of her high heels gradually becoming inaudible, leaving Petra with the nurse who looked like she was going to pass out any second, constantly wiping her palms on her nurse dress.

"Um, this way, please," she stammered. "Miss Ral," she added quickly. She took out a set of keys and carefully selected one to unlock the door. "I'll introduce you to your roommate." Petra could have sworn that she had hesitated to open the door for a few seconds. Was her roommate that unappealing to be with? What did she get into this hospital for? Maybe she was a serial killer? A maniac?
She couldn't help but feel some sense of apprehension. This roommate of her was going to be the person she would be living with for God knows how long.

"...Miss Zoe?" the nurse said as she partially opened the door. "Your new roommate has arrived." She opened the door completely then, revealing a female figure looming over a desk in the corner of the room, her back facing the door. Her dark brown hair was tied in a scraggly ponytail and she was furiously writing on what looked like a journal. The figure turned around, revealing the rest of her features. She looked around Petra's age, perhaps a bit older. Large glasses sat on a large nose and covered most of her brown eyes, but even so, her eyes had a sharp glint that showed something Petra could not exactly identify.

The girl studied Petra, as if taking in every bit of information about her from her appearance, then smiled with a look of approval (Petra did not know whether to be relieved or scared). Then suddenly, she walked towards Petra, put an arm on her slight shoulder (she was much taller now that she was closer) and laughed loudly.

"Welcome to the laboratory!" she said. "I'm Hange Zoe, and you shall be my companion in this wonderful adventure! I shall show you the ways of our fellow soldiers, and we can form bonds that will last forever!" She ended with another hearty laugh. Petra felt the slight urge to stay an at least 5 foot distance away from this girl. She now understood why her nurse looked so jittery. But she managed a nervous smile and nodded.

Her nurse coughed to get the two roommates' attentions. "I'll show Miss Ral around the room, so..."

"No worries!" Hange interrupted. "I'll show her around. It will be our first bonding moment!"

"Um, all right. I guess it will be fine if I stay here while you show her."

Hange broke into a large smile that reminded Petra of a small child at a toy store. "Well then, come inside the room! No need to be shy here." Petra wasn't sure who was more scared—her or the nurse.

The first thing Petra noticed about the room was that it looked more like two rooms. It was separated into two areas that were the same size. Each side of the room had a plain bed, a nightstand, a small dresser, a waste bin, and a desk with a chair. In the center of the room there was a medium sized bookcase that held an infinite amount of journals and pieces of paper, as well as a small window. A small corridor led to what appeared to be a bathroom.

"This will be your part of the room, Miss Ral." The nurse motioned towards the area on the left, which was kept adequately tidy.

"But soon it will look like my side," Hange declared, waving a hand at her side of the room, which looked like it had just been through a tornado, with stray clothes lying on the floor, stacks of books and paper sitting on her desk, and a random assortment of photographs and diagrams taped on the wall next to her desk.

"We just cleaned it yesterday, too," the nurse muttered just within Petra's line of hearing. "Feel free to look around your room."

Petra opened the dresser to find a several plain white hospital gowns. Noticing her disappointment, the nurse added, "We will try to retrieve your old clothes if the gowns are not to your liking. We will also give you casual attire as soon as we can."

The rest of the room seemed rather adequate. She eyed the pictures on Hange's wall, particularly the photographs of her with what seemed to be her friends. She felt a twinge of envy, as she did not remember having such people close to her. Or maybe she didn't have any close friends in the first place. She vaguely recalled the faces of some people from school, but could not determine their significance to her. Maybe they were just faces she passed through at the hallway. No one really visited her at Maria's Hospital, so that had to say something.

The nurse handed her a folder and a journal. Opening the folder, Petra found several documents, ranging from the familiar medical patient surveys to what looked like a school schedule.

"You will have to attend classes during your stay here," the nurse informed. "We will incorporate therapy sessions every day as well, and school will be different than that of an average public school education." Petra couldn't help but feel slightly shocked. She had expected to just spend the rest of her days in a hospital cot until some miracle brought back her memories. She remembered the basics parts of school life, and although none of it seemed particularly bad, none of it seemed particularly great either. Nothing about school life stood out that much to her.

The nurse shifted a bit. "Well, I think we settled everything for the first day, so, um, I'll leave you to get ready for bed now. Oh, yes, something else." She scrounged around her pocket and pulled out a small cord with a piece of metal with a button attached to it.

"Here, put this around your wrist," she said as she handed it to Petra. "It's an emergency help button. Push the button if anything bad happens." She looked at Hange when saying the sentence. "Be sure not to lose it, and keep it with you all the time."

"Thank you," Petra said. She noted the nurse's look of surprise. "Is something wrong?" she asked.

"N-no, it's just that I was surprised that you finally talked. Most patients are either silent for days or talk on the first day..." she trailed off. "I'm sorry, that was rude. I'll be leaving now." She bowed before leaving the room.

After getting into one of the white hospital gowns and bathing herself, Petra laid herself in her bed. It was more comfortable than it looked, but it was not enough to calm her down. A pang of fear went through her. Just what exactly was she supposed to do here?

"So," Hange started, making her way to her own bed and leaning her head against the wall, her knees curled up against her chest. "What's your reason?"

"E-excuse me?" Petra asked.

"What got you here?" Hange questioned.

"Lacunar amnesia, traumatic amnesia, source amnesia, partial retrograde amnesia, severe anxiety, insomnia..." she listed

"No, I mean how did you get those," Hange interrupted. "Murder? Victim? Trauma? Acquired disorder?"

She felt slightly put off by her straightforward nature of the question. "Got hit in the head with a beer bottle at a party. The doctors say that it might also have something to do with the fact that I saw my mother die a few years back, but they still aren't sure. They say that it's a combination of physical and mental trauma that got me here." Petra felt the need to say something to continue the conversation, even if the topic was rather disconcerting. "Um... what about you?" she asked.

Hange straightened her back and her mouth formed a straight line. Perhaps the topic is too sensitive, Petra thought. To her surprise, Hange answered her.

"My best friend got killed by some classmate who was a gang member. I got angry and tracked down the gang, and killed the guy. Killed some other people in the gang who helped him kill her. Injured a bunch of people. One of those guys I injured turned out to be close to the church. Stupid that they didn't care that I killed three people, but once I broke some church boy's arm they send me here, isn't it?"

She felt some awe that she could talk about this matter so flippantly. Perhaps she had recounted the story so many times that it has lost meaning to her.

"But it's okay, I'm fine now," Hange reassured, then chuckled lightly, much different from the wild cackling she had done earlier. "Listen to what I'm saying. 'I'm fine.' If I was fine, would I be in this place?" Another small laugh. It wasn't until now when Petra realized that there was more to Hange than meets the eye. Something told her that her story had more to it that the few sentences she had just said.

"Hey," Hange said. "You said your mom got killed. What about your dad?" she asked. The last word made Petra cringe a bit. Dad, she thought, what a strange word to call him.

"It's not like he didn't love me or anything," she started. "But I feel like it wasn't until the accident when he actually showed signs of caring about me." Hange looked at her and only gave a nod of her head.

Petra continued on. "He always wanted what was best for me, but sometimes I felt like he thought what he thought was best was always right. He was a businessman, you see. And I was the only child so I guess he wanted to pass on the trade to me. So he tried to get me to do a lot of professional things. Tried to make sure I got the best grades. Wanted me to be the best at everything. When I wasn't the best, he would tell me that it was okay, but he still looked disappointed in me even then. Then he started talking to me about marriage. Pretty old fashioned of him, right? And then he would question my decisions all the time. But since I got into the hospital, he'd been visiting me every time he could. But he's busy with his business so he only visited twice when I was at Maria's. I guess I should feel grateful that he sent me here, because it seems like a good place, but I still kind of wish he could visit me from time to time." She paused. It's been a while since she's talked this much about herself to anyone. It was a fresh breath from having to talk to doctors about what she remembered (more of what she couldn't remember).

Hange stayed silent after a while. "I see," she finally said. It was silent for a while.

"Well, I should let you sleep. First night is always hard," Hange said as she turned off the lights. Petra noted her calmer tone in voice, almost motherly. "Hey, it'll be fine. If anything happens, you can talk about it to me. I'll introduce you to some of my friends tomorrow. I have a feeling you'll like them."

Nodding her head Petra curled up under the bedsheets. It'll be fine, she reassured herself.

A/N: Please tell me if there is anything wrong you see in this fic (spelling, logic). I do not have that much knowledge about mental disorders and wards, so do tell me if anything is really unrealistic (but keep in mind I do have to keep some stuff unrealistic. This is fiction after all~) P.S. Who got the significance of Petra's room number?

Moving on I need help on what the other characters did such as:

Eren
Mikasa
Armin
Levi
Jean
The rest of Squad Levi
Krista
Other major characters in SnK

So if you don't mind, please tell me your ideas on what these characters got into the hospital for.

Thank you for reading and please tell me what you think!
