This one here explores the FitzSimmons relationship and has a bittersweet ending. Enjoy!

stranger ˈstreɪn(d)ʒə/ a person whom one does not know or with whom one is not familiar.

They didn't know each other, not yet. Jemma Simmons never had what she called true friends when she was in school, a result of having skipped so many years. Leopold Fitz was also in that same situation. It wasn't until that S.H.I.E.L.D. Academy that they both laid eyes on each other for the first time. And neither knew what the years would have in store for both of them.

enemy ˈɛnəmi/ a person who is actively opposed or hostile to someone or something.

He hated her. That was the only explanation that could be provided for why he ignored her. There was no other reason. She had annoyed him, following him around non-stop like some sort of puppy dog. She hated herself for that. She had lost a chance at a friendship, one that she really wanted. He was her age, the only one here that was her age, and his intelligence was so similar to hers. He would be able to understand her, unlike so many people in her life (even her parents, despite how hard they tried they were unable to keep up with their daughter who was a genius, a prodigy). And not to mention the fact that he was oh so handsome. She wondered if they could be friends, something more than enemies. And also, if they could be something more than friends…

acquaintance əˈkweɪnt(ə)ns/ a person one knows slightly, but who is not a close friend.

It was the day that they got paired together in Chem Lab that Fitz was finally able to say something that he deemed smart enough for Jemma Simmons. It was a joke, something that was able to make her laugh. Watching her face light up was something truly amazing, something that he wanted to able to do for many years to come if it were possible. "I think we got off on the wrong foot," she said, looking up from her microscope. "We should start again."

He nodded. He held out his hand. "Fitz."

"Simmons."

"I'm engineering."

"I'm biochem."

friend frɛnd a person with whom one has a bond of mutual affection, typically one exclusive of sexual or family relations.

It was in the weeks that followed after the day they got paired up in Chem Lab that they became friends. They never talked of the weeks before that, but they were still strong friends nevertheless. Jemma had finally found someone who understood her, someone who thought along the same wavelengths as her. Fitz found himself in a similar position with her, and he had never been happier in his life when he was with her. Her laughter was infectious, her smile radiant and she always saw the best in everyone. Fitz could only hope that nothing would ever destroy what they had.

best friend bɛst/ frɛnd a person's closest friend.

"Fitz."

"Simmons."

"He's engineering."

"She's biochem."

It became the way they introduced each other (and themselves), and the two young scientists soon became well known for never being apart, and for always finishing each other's sentences. Many people thought they were dating ("Oh god no!" "We're just friends!"), but they weren't. They were simply two friends, who were extremely close, that enjoyed lying on the sofa in the evenings, watching Doctor Who together, curled up under one blanket.

It was one night, when Jemma had had one drink too many, and was clinging onto Fitz as he guided her home when she blurted out that she loved him, that he was the greatest friend that she had ever had and nothing could ever change that.

colleague ˈkɒliːɡ/ a person with whom one works in a profession or business.

After Jemma returned from her undercover at Hydra, she felt as if she were more alone in the world than she had ever previously been. She still had friendships with Skye and all, and Bobbi had taken her under her wing but it was her fractured relationship that had hurt the most. They were barely talking at this point, only when it related to their work. They weren't friends anymore and they were only talking when it came to work, and those discussions where more arguments than anything else. And they were only talking when it came to work. And it hurt more than anything else. So Jemma cried herself to sleep most nights, trying to think of a way to heal their fractured relationship.

boyfriend ˈbɔɪfrɛnd/ a person's regular male companion with whom they have a romantic or sexual relationship.

Before the relationship stage came the stage where they were Fitzsimmons again. And being in a relationship, it wasn't that different from being the close friends that they were, that had made them Fitzsimmons, but with more kissing and sex. Neither of which Jemma minded. She loved being with Fitz, his reassuring presence always near her. His fingers laced through hers, him finishing her every though, being on the same wavelength as her. His lips dancing in her hair, their foreheads touching. His protective arm around her as they lay in bed at night, the beat of his heart. It had taken them years to get there. And Jemma was more than happy to be able to call Leopold Fitz her boyfriend. She felt honoured to have that privilege.

fiancée fee-ahn-sey a woman engaged to be married.

When Leopold Fitz proposed to Jemma Simmons, seeing the look of pure delight on her face, that was a moment he wanted to relive forever, he wanted to create that moment every day, wanted to see that look on her face for the rest of his life. It was joy and happiness in its purest and simplest form. It was a simple proposal, nothing elaborate, a year after what they classed as their first date, in a small Italian restaurant that was a favourite to both of them. The days after were truly blissful, waking up with her nestled in beside him, placing a kiss on her forehead. It was definitely something that he wanted to do for the rest of his life. He felt truly privileged to be able to call Jemma Simmons his fiancée.

wife /wʌɪf/ a married woman considered in relation to her spouse.

Fitz didn't even make himself promise that he wouldn't cry at the wedding. He knew that he wouldn't be able to keep his word. He knew this would be the happiest day of their life, the day that they would remember for so many years. But seeing her walk down that aisle, a bouquet of flowers in her hand, all dressed in white, he couldn't fight back any tears. She was more than beautiful, she was more than radiant. She was truly something else, and he didn't know what he had ever done to deserve her as his wife. But that didn't matter. As she was now standing in front of him, tears sparkling in her eyes as he pulled back the veil. "Jems," he whispered, and she smiled at him. "I love you," she mouthed as the ceremony continued around them. Vows were said, no one objected, and the words that bound them together were said. "I now pronounce you man and wife."

They shared their first kiss as a newlywed couple, oblivious to the cheers and cries around them, only knowing each other in that moment.

soulmate ˈsəʊlmeɪt/ a person ideally suited to another as a close friend or romantic partner.

The relationship that they had wasn't purely romantic or sexual, its roots weren't buried there. No, their relationship had friendship as their primary focus and Fitz knew that was the reason that they had been together for sixty year, both of them now approaching ninety. They were a happy sixty years, with many memories, so much joy and laugher. Early mornings, rainy afternoons and lazy evenings. Picture albums full of holidays and baking. Two amazing children, 6 wonderful grandchildren, and one new born great grandchild.

But Jemma's health was failing her, old age finally catching up on her. Doctors had told him before he came in to visit her that she didn't have long left, that this may be his last visit to see her. He bit back the tears as they told her that. But still he knocked on the door, and waited for her to tell him to come in.

His hands behind his back, he made his way across the room, and upon reaching her bed, he handed her a massive bunch of flowers, bringing a massive smile to her face.

"You shouldn't have," she said as she laid them on the bed beside her, and he took the seat, reaching for her hand.

"It's our sixtieth wedding anniversary, of course I had to."

"Oh," was her reply and he lifted her hand, bringing it to his lips and kissed it.

"I love you," he whispered.

She nodded, and her eyes closed. Then opened them again. "Fitz," her voice was weak and the Fitz realised that the doctors were right, they were preparing him for the worst. The day that he never wanted to come. "Sixty years we were married and we spent so many before that together, and Leopold FitzSimmons, I wouldn't change a thing."

Her eyes fluttered shut after that but did not open again this time. He stayed with her, murmuring reassurances until her last breath.

I'm sorry. And fun fact; this took longer to format than to write. So close to tears when dealing with it!
