AU where FitzSimmons have been married since before joining the team and Coulson is the only one who knows. Will follow the AOS story line for the most part but will probably veer off at some point. Rated T. I'm not planning on having any M rated chapters at the moment, but things could always change.

Jemma Simmons was nervous for her first day on the bus. Although it had been her who'd had to convince Leo that joining Coulson's team was an amazing opportunity, now that they gathering up all of their things and were moving them into the lab, Jemma couldn't help but have second thoughts. She could tell that Leo was nervous as well, and wasn't at all surprised when their nerves led to them bickering over the Night-Night Gun. They were stopped in their tracks, however, by a man in a suit who could only be a specialist, based on his attire and physique.
"FitzSimmons?" he asked in a tone that suggested he would rather be anywhere else at the moment. Without even thinking about it, Jemma immediately pointed to Leo and introduced him, while he did the same to her. It was something they'd been doing since their days at the Academy, and it was a very difficult habit to break. Agent Ward, who's identity had been confirmed when he'd mentioned Coulson, gave his comm receiver to Leo and looked thoroughly unimpressed when Leo proceeded to smash the device. Jemma just smiled, knowing how much Leo secretly loved to destroy things. Getting right to work, Jemma took a DNA sample from the inside of Ward's cheek while he was trying to ask about the comm receiver. She asked Ward if he was excited to be on the bus, and wasn't deterred by his sarcastic reply, keeping a smile on her face as she and Leo began the process of encoding the comm receiver.
It was two hours by the time they'd finished the process and then unpacked all of their supplies and safely stowed them away in the lab. All that was left to do was unpack their personal items and set up their bunk. Coulson had shown them where it was when they'd first entered the bus. While all of the other bunks were cramped and held tiny twin-sized beds, their bunk was slightly more spacious and held a double bed. It was still very small, but they were used to living in such conditions by now. The room even had two doors, so the rest of the team wouldn't become suspicious about why they stayed together. Coulson had known that they were married before he'd even asked them to join his team, and had been very accommodating.
It wasn't common for S.H.I.E.L.D. agents to get married, let alone for two of them to marry each other, but Jemma and Leo hadn't let that stop them. After all, they had never planned on entering the field, and had always thought that they would just stay in the lab. They had only been married a month when Coulson recruited them to his team, and very few people were even aware that they had gotten married. Of course, all the higher-ups knew, and it was in their files, but Jemma still went by Simmons, and they'd already been so close that their relationship hadn't really changed much. Jemma smiled as she placed their wedding photo atop their new dresser. It was her favourite one. She was wearing a simple white dress, and Leo had never looked more handsome in his tuxedo. They had their arms thrown around each other and had huge smiles on their faces. They'd both been so happy that day. They'd gotten married in England, at the quaint little church just down the road from Jemma's childhood home. Their families had been the only ones to attend, but the day had been perfect. Jemma twirled the necklace that held her wedding ring and sighed. She and Leo had agreed not to tell the team that they were married. It wasn't that they wanted to keep it a secret, they just didn't want to advertise it and they thought that it would be easier if the team didn't know. They were just putting the last of their things away, including their Doctor Who DVD collection, when Coulson knocked on their door and peered his head in.
"Briefing in five," he said, looking around their room. "I like what you've done with the place." With that he left, and they'd hurriedly put the finishing touches on their room before meeting the rest of the team. After getting the background information on Centipede, they headed to the site of the explosion with Agent May, where Leo was thrilled to finally get to use the D.W.A.R.F.s. They were like proud parents, watching them zoom around the destroyed lab, picking up things that could be easily missed by untrained eyes. This was what they loved about science; being able to build something that could do a job that no person could. Jemma was no longer nervous about their new team. She and Leo were quickly finding their place in the field.
Later, when Coulson demanded that they find some way to stop Mike Peterson without killing him, Jemma thought she was facing the impossible. Nevertheless, she and Leo did everything they could to find a solution. She'd pretended it was an exam. That was the only way she could keep thinking clearly. An exam was much more manageable than stopping a man from exploding and killing innocent people. She just had to stay calm. She heard Leo curse as his simulation again resulted in death, and she knew she had to keep him calm as well. They spoke the same language, and that was partly what made them such a great team.
They had finally managed to create a dendrotoxin that would have the desired affect on Mike Peterson, and as she ran into the train station, she only hoped that Leo would be able to reach Ward in time. She heard a shot ring out and saw Mike fall to the floor. Time felt as though it was moving in slow motion as she ran towards the man lying motionless on the floor. She felt for a pulse and checked his pupils before turning to Coulson and giving him a tired smile. She and Leo had done it. They had saved Mike Peterson. She had never felt so relieved in her life. Looking up to the balcony, she saw Leo give her a thumbs up from where he stood next to Ward.
After Mike had been taken into the ambulance and transported to a nearby hospital, the team returned to the bus. Coulson patted them on the back and told them that they had the rest of the day off. All Jemma wanted to do was eat Chinese food with Leo, and perhaps watch some Doctor Who. However, fate had other plans. They'd just started relaxing in the kitchen with their takeout and beer when the call came in about an 0-8-4 that S.H.I.E.L.D. wanted them to confirm. Ward called Coulson, who told them all to get some sleep and that they'd be taking off as soon as he got back to the airfield.
Jemma and Leo looked at each other with wide eyes. An 0-8-4! They couldn't believe it. They took the rest of their dinner to their bunk, where they both rambled on in excitement about what the 0-8-4 could be. They finally decided that it would be a good idea to try to get a couple hours of sleep before they reached their destination. As they laid in bed, Jemma curled around Leo with her head on his chest, it finally sunk in that their mission could be dangerous.
"Leo?" Jemma asked, tilting her head upwards to meet his eyes.
"Yeah, Jem?" he replied.
"Are you scared?" Leo paused for a moment.
"Of course I am, Jemma," he said. "But not of something happening to me. I'm scared something will happen to you. I don't think I could live with myself if I ever lost you." Tears pooled in Jemma's eyes as she reached up to kiss him.
"Don't worry," she said, breaking off the kiss. "I'm not going anywhere."
Thanks for reading! Let me know what you think and I'll hopefully be posting the next chapter soon.
