Yes, there are many fanfictions that focus on their friendship and adventures without any sexual content. They are often depicted as comrades, with Sabine's skills and Hera's leadership working together in the fight against the Empire.
Another theme could be their contributions to the Rebel cause. Sabine's combat skills and Hera's piloting and leadership are important aspects. For example, in some fanfictions, they work together to plan and execute missions against the Empire. They also might face challenges within the Rebel Alliance, like dealing with different opinions from other members, but they always find a way to support each other through it.
In a lot of fanfiction, Sabine and Ezra are often depicted as being in love. Fans are drawn to the idea of their relationship evolving in that way because of the chemistry and bond they share in the series. Their adventures together and the way they support each other can easily be translated into a romantic relationship in the creative world of fanfiction.
In some fanfictions, Sabine's death could be a very tragic and emotional event. It might be due to a heroic sacrifice in a battle against the Empire. For example, she could sacrifice herself to save her friends or to protect a crucial piece of information from falling into the wrong hands.
One idea could be to focus on how Hera's pregnancy affects her role in the Rebellion. Maybe she has to take a step back from some of the more dangerous missions, which causes her to feel frustrated as she's so used to being in the thick of things. But her fellow rebels support her and find new ways for her to contribute.
One great Sabine romance fanfiction is 'A New Connection'. It beautifully weaves a story where Sabine meets a new character during a mission. Their relationship develops gradually as they face various challenges together. The author does an amazing job of capturing Sabine's personality and how she would interact in a romantic situation.
One possible fanfiction could be about Sabine getting jealous when Ezra starts spending more time with a new female character. Maybe she starts acting out in training sessions, being more aggressive than usual. This jealousy could stem from her unspoken feelings for Ezra that she hasn't fully realized yet.
One great fanfiction could be where Sabine discovers Ezra in a long - forgotten Jedi temple. In this story, Sabine has been on a solo mission to explore ancient Jedi sites. By chance, she stumbles upon a hidden chamber where Ezra has been in some sort of stasis or exile. Their reunion is filled with a mix of emotions, from shock to overwhelming joy.
I really like the fanfiction 'Hera and Kanan: The Unspoken Alliance'. In this story, the author beautifully portrays the chemistry between Hera and Kanan. It's full of action scenes where they fight side by side, but also tender moments that show their growing affection. Another interesting piece is 'Kanan's Promise to Hera'. It's set during a particularly dangerous mission, and Kanan makes a promise to Hera that he'll always be there for her. This adds a layer of depth to their relationship. Then there's 'The Path of Hera and Kanan' which follows their journey through different planets and how they support each other in every step.
One great Sabine and Ezra fanfic could be one where they go on a secret mission together. It might explore their growing bond as they face challenges. Maybe they have to infiltrate an Imperial base, and along the way, they learn more about each other's pasts. Their different skills, Sabine's artistry and combat skills and Ezra's connection to the Force, would make for an interesting dynamic during the mission.
