Hello, this is my first Agents of S.H.I.E.L.D fanfic! I've been really inspired by the FitzSimmons relationship so I was inspired to write this! Also, they are not romantically paired in this fic. It's about their loving brother/sister dynamic. I really hope you enjoy, please review!

S.H.I.E.L.D training camp carried far more surprises than Leo Fitz could ever have anticipated. It was not the seemingly never-ending equations he was tested with or the computer graphics that jumped off the screen and moved when you swiped your fingers through the air but instead it was a shock that came on his first day, after only being in his dorm for about four hours at the most.

He had already settled in quite nicely. He had thrown his stuff on the bed, unpacked his laptop and was researching about the training programme so that he was prepared for the next few weeks of his life which, at the time, were unknown and slightly scary. He sat there in silence, the only noise being hushed muttering from agents walking past his room or the occasional click of his mouse. The room was simple, nothing flashy or too daunting. The walls were a steely blue, the carpet was a dark grey, there was a lamp in one corner and a television in the other. There were two small beds and one cupboard. There was also a small bathroom and that was it. Fitz was rather happy that it wasn't too unfamiliar. It reminded him of a hotel room he would stay in on holidays when he was just a boy. The only thing that was a bit unsettling was the S.H.I.E.L.D logo which was plastered to walls, bottles of water, coat hangers and even slippers and bath robes. To be honest, he was rather fond of the S.H.I.E.L.D bath robes.

The stillness was interrupted by the click of the lock on his room. In complete panic, he slammed the lid of his laptop down and stood up, hitting his knee on the desk as he did so and wincing in pain. The door opened and a figure walked in, holding about three boxes piled up in it's hands. The figure stopped in the doorway.

"Oh, you must be Fitz. I'm sharing a dorm with you," it said in a cute English accent which was a bit of a shock to Fitz. He suddenly realised that this figure was a woman. His heart skipped a beat and he immediately blushed because of the mess in his room. He just stood there, frozen, trying to find words to say. Eventually, after a rather awkward silence, he spoke,

"Yes, that's me. Umm... sorry about the mess, I wasn't expecting a roommate or at least not a woman. Not that I don't want a woman... as a roommate. It's just that I wasn't expecting you. I'm sure you're nice and all but... yeah. There's two beds so I should have been waiting for you but I didn't think. Sorry. I can tidy the place up if you want." He stumbled over his words nervously. The shock of a woman being in his room was too much for him and he got slightly awe-struck. Adding to the embarrassment of his room was the fact that she looked so smart in her blazer and dark skinny jeans and he just wore dirty jeans, a checkered shirt, a tie and a pair of old converse. On top of this, he was almost positive she had seen him bang his knee which was now throbbing with pain. She smiled politely at him and laughed slightly underneath her breath.

"No, it's okay," she said, walking further into the room and placing her boxes on top of the bed which wasn't already occupied. She noticed the bags and coat strewn across his bed. "Actually, we might have to clean up a little bit," she added. Fitz immediately picked up his bags and coat, blushing furiously.

"Aye, yes, of course," he stammered before cursing quietly, putting his bag in the cupboard and hanging his coat up on one of the hangers. "I'll unpack later." She smiled at him.

"I'm Jemma, by the way, Jemma Simmons," she chirped, holding out her hand to him.

"Leo Fitz," he replied, shaking her hand.

Simmons began to unpack her belongings whilst Fitz sat on his bed, awkwardly. He didn't know what to do. Surely it would be rude to just sit back down on his computer but was it creepy to just stare at her? She took a small pile of lacy bras and knickers out of one of her boxes and Fitz immediately looked away, clearing his throat. He decided it would be best to start a conversation with this stranger.

"So, what do you specialise in?" he asked. Inside his head he kept repeating the word 'science' hopefully. He wanted someone who would listen to him when he talked about rocket science or at least wouldn't get irritated when he watched monkey videos on the internet in his spare time. Simmons turned around, eyebrows raised in interest.

"Oh, I study biochem," she replied. Thank god, Fitz thought. The topic of this conversation suddenly sparked a fear in Simmons as well. She suddenly became afraid that she was sharing a dorm with a training field agent who would want to spend time alone and become grouchy and irritable and get annoyed with her whenever she wanted to watch Snow White and the Seven Dwarves or give hour-long lectures in the evening about nuclei, genetics and hormones. "What do you study?" she asked sheepishly. The length of time from the moment the asked the question to his answer felt like forever.

"Engineering," he answered. She sighed in relief. Fitz furrowed his brows. "What was that for?"

"Nothing," she replied, "Your accent's cool. Where in Scotland are you from?" she asked, taking the final few things from her boxes and putting them in the appropriate places.

"Glasgow, born and raised. You?" he asked.

"London," she replied. She took a UK flag from her box and looked at it. "We're both a long way from home, aren't we, Fitz?" she asked, feeling a little bit homesick whilst looking at the flag. Fitz nodded and chuckled slightly. It wasn't a happy chuckle, however. Their homes, families and everything they had ever known was miles and miles away now. "I think this should go up on the wall," Simmons said, looking around for a space before pulling her tape from her box and taping to the wall behind their headboards. She stood back and looked at it. "Is it uneven?" she asked, tilting her head to both sides. Fitz stood next to her,

"No, it's okay," he said.

Jemma Simmons smiled and looked over to Fitz, her new roommate, and realised that the flag was not her only link to home. He was. He let her know that she isn't alone in this new place.

On top of this, she was becoming very fond of this Leo Fitz, the man who she first met after he hit his knee on the desk.
