FitzSimmons

"The one thing I've known without a doubt–the whole time–is you and Fitz belong together."

- Daisy Johnson to Jemma, Agents of S.H.I.E.L.D.

FitzSimmons is the het ship between Leo and Jemma from the Agents of S.H.I.E.L.D. fandom.

Pre-series
Jemma and Leo met at the S.H.I.E.L.D. Academy of Science and Technology, and they quickly became best friends. To Leo's dismay, Jemma started dating a classmate named Milton. Luckily, the relationship did not work out.

The two graduated from the academy three years early. Craving adventure, Jemma convinced Leo to seek out a field assignment with her.

Season 1
Jemma and Leo were recruited to Phil Coulson's team. They went on many missions together. When Jemma was infected with a lethal alien virus, Leo refused to leave her side, working tirelessly with her to develop a cure.

During HYDRA's attempt to take over S.H.I.E.L.D., Jemma and Leo were taken aboard the Bus by their teammate Grant Ward, who revealed that he was part of HYDRA. Ward was ordered to kill the two. He locked them in a Medical Pod and ejected them into the Atlantic Ocean. The pod sank to the bottom of the ocean. Though Leo felt their situation was hopeless, Jemma devised a way to escape without the water pressure crushing them. He then gave her the only air device and confessed his feelings for her. He intended to sacrifice himself so that she could live, but Jemma used her last strength to swim with him to the surface. The two were rescued by Nick Fury.

Season 2
Leo had sustained brain damage from the events prior. When Jemma left S.H.I.E.L.D. suddenly, Leo's mental state spiraled downward, and he began having hallucinations of her. He was unaware that Coulson had placed her on an undercover assignment with HYDRA; he believed that she'd left because she did not reciprocate his feelings. When she returned months later, their relationship had become tense and awkward. Leo found himself unable to work with her anymore.

The two slowly reconciled with each other. After S.H.I.E.L.D. had stopped the war with the Inhumans and acquired the Monolith, Leo awkwardly asked Jemma out to dinner. She agreed, and he left the room. Once he left, the Monolith morphed into liquid and pulled Jemma inside it, transporting her to a faraway planet called Maveth. The Monolith then returned to solid form.

Season 3
For six months, Leo tirelessly studied the Monolith, never giving up hope that he would be able to find her. He even kept the reservation at the restaurant where they were meant to have their date. He became desperate, and he broke down one day, hitting the stone and screaming at it to do something. The Monolith remained solid, but Leo noticed a strange sand on his fingers. He analyzed it and realized that its composition was impossible for Earth, confirming his theory that the Monolith was a transportation device.

During her time on Maveth, Jemma recorded video logs on her phone, talking about her hopes for her future with Leo in order to stay sane.

Using Daisy's vibration powers to activate the Monolith, Leo entered it and rescued Jemma, pulling her safely back to Earth just before the stone exploded. He stayed by Jemma's side as she recovered from her traumatic experience. He was dismayed to learn that she'd fallen in love with another man, Will Daniels, while on Maveth, but he put her happiness above his own feelings and agreed to help her figure out a way back to the planet to save him.

Tensions rose between Jemma and Leo, culminating in an argument; Jemma was angry at herself to asking Leo to help when she knew how he felt about her, and Leo was angry at the universe for tearing them apart so many times. The argument ended as Leo kissed her and told her that they were cursed.

Leo and Jemma were captured by HYDRA, who intended to reopen the portal to Maveth in order for their Inhuman leader, Hive, to return from his banishment. Leo refused to help them, but quickly gave in when Giyera and Ward began to torture Jemma. She stayed behind while Leo was forced to accompany a squad of HYDRA soldiers into the portal, with Coulson joining at the last second. Leo rescued a man who he believed to be Will; however, it was Hive. Hive had killed him after Jemma's rescue and was using his body as a host. Leo and Coulson escaped back to Earth. Leo comforted Jemma as she grieved for Will.

Back at the lab in the Playground, Jemma told Leo she missed their friendship. They introduced themselves to each other again, starting their relationship over. They later kissed, realizing that they couldn't waste any more time.

While on a mission to find Dr. Holden Radcliffe, Leo and Jemma discussed the future of their relationship. The mission went awry when Hive arrived to kidnap Radcliffe, and Jemma and Leo were separated. Jemma waited for him anxiously in their hotel room. She was relieved when he returned, and the two consummated their relationship.

After Hive was captured, Jemma planned a vacation for herself and Leo to the Seychelles. However their plans were interrupted when Hive escaped the Gel Matrix Box he had been trapped in.

Season 4
Six months later, Jeffrey Mace had replaced Coulson as the director of S.H.I.E.L.D. Jemma had become the head of the lab, working as the Special Adviser to the Director in Science and Technology. She and Leo barely had time to see other outside of work anymore. They were looking for an apartment to live together.

Upon discovering the existence of Aide, Radcliffe's Life Model Decoy, she grew angry at Leo for keeping Aida a secret from her. As part of Mace's deal with Senator Ellen Nadeer, Jemma was summoned to perform a mission for her. She was sent to a secret location while wearing a hood. Mace refused to disclose her location to anyone, worrying Leo. Jemma was eventually returned to the Playground and reunited with Leo, who had barely escaped Hell. The two hugged each other, making up from their argument earlier.

She later comforted him after Radcliffe's betrayal, giving him words of encouragement that helped him figure out how to access the brain of Radcliffe's LMD.

While on a mission to infiltrate Krasnoyark Krai's naval base, Leo, Coulson, and Alphonso Mackenzie were captured and replaced with LMDs. Aida, who had rebelled against Radcliffe, placed the three of them in the Framework, a simulated reality developed by Leo and Radcliffe. Each one had their greatest regret reversed. For Leo, this was his father Alistair abandoning him and his mother when he was a child. In the Framework, Alistair took him with him when he left and shaped him into a cold, cruel man. Leo was HYDRA's second-in-command and was known as the Doctor for his work on his lethal experimentation on Inhumans.

When Jemma and Daisy uploaded themselves into the Framework to rescue the three of them, Jemma refused to give up hope that Leo could be saved, insisting that he was still the man she loved. Leo had no memory of her, however, and was in a relationship with Madame Hydra, Aida's Framework version. Jemma was horrified when Leo murdered Agnes Kitsworth in cold blood. After learning that his father was the reason for his ruthlessness, Jemma went to Alistair's house to confront him and demand help. The confrontation resulted in a fight, and she had no choice but to shoot him. When Leo learned of his father's death, he swore revenge on Jemma.

Daisy and Jemma took Melinda May, Coulson, and Mack to the Framework's exit. Radcliffe told Leo where it was, and he took a HYDRA team to apprehend Jemma. He nearly killed her, but Radcliffe disarmed him, revealing that he'd planned to trick Leo into leaving the Framework.

Back in the real world, Leo was haunted by the terrible things his Framework version had done. Aida, who had built a real body for herself, confessed her love for him. When Leo told her he could only love Jemma, Aida became insane and enraged, and set out on a vendetta against him and S.H.I.E.L.D. Jemma comforted him afterwards, both traumatized but glad to be reunited.

Season 5
After defeating Aida, the entire team except for Leo was kidnapped and transported to the future. With the help of Lance Hunter and a Chronicom named Enoch, Leo learned where his friends had gone. He went into cryogenic stasis in order to awaken in the future to be reunited with his friends. He infiltrated the Lighthouse, posing as a Marauder named Boshtok. Seeing Jemma, who had been enslaved by the Kree Kasius, he went over to her and discreetly spoke with her, confessing his love and asking her to marry him. She had, however, been outfitted with a device that disabled her hearing, and did not hear him. Leo then demanded that Kasius disable the device, to which he complied.

As Daisy was forced to fight the Kree Sinara to demonstrate her powers to potential buyers, Leo and Jemma sprung into action, attacking Kasius and jumping into the arena with Daisy. Reunited with each other, the two shared a passionate kiss, and Jemma asked him to marry her, which he immediately agreed to. The three then made their escape. Meeting back up with Coulson, Mack, and May, they eventually found their way back to the present, along with Deke Shaw. They were transported to the Lighthouse as it was in their time, where they found three Monoliths in a storage room.

When a Kree Orb was brought into the storage room, it exploded, destroying the Monoliths. The destruction of the Monoliths tore a hole in space-time, opening a rift into another dimension that could manifest people's deepest fears. It caused a forest to instantly sprout on one of the Lighthouse's floors; this was one of Deke's fears. Coulson used a Gravity Containment Device powered by Deke's Gravity Puck to contain the rift. Afterwards, Jemma and Leo married each other in the newly-created forest.

The rift, however, had not been completely contained, and began manifesting people's fears again. The two began to work on another Gravity Containment Device. They were able to obtain raw gravitonium required for the device to work, but had no way of compressing it to fit inside the device. The immense stress of it caused Leo to suffer a mental break, and the Doctor's personality from the Framework manifested within him. Against Daisy's wishes, he removed the power inhibitor that she'd been outfitted with while in the future, allowing her to use her powers to compress the gravitonium into the device. He was then locked up.

Horrified by himself, and still believing his actions to be right, Leo questioned the future of his marriage with Jemma. She became overwhelmed by everything that had happened, and was comforted by Deke. He assured her that her future with Leo still existed, as he was their grandson.
