Guilt is a big theme as well. After hurting Padme, Anakin would likely be consumed by guilt, which could drive his character development in different directions. This guilt can also be a catalyst for him to either fully embrace the Dark Side or try to find a way back to the Light, depending on the direction of the fanfiction.
The theme of sacrifice also pops up often. Padme is often put in situations where she has to sacrifice her own happiness or safety for Anakin or for the greater good of the galaxy. And Anakin too may have to sacrifice his power or desires to be with Padme in a more positive way.
One common theme is love. Anakin's love for both Shmi and Padme is often explored. His love for Shmi as his mother and his deep, romantic love for Padme. Another theme is sacrifice. Shmi's sacrifice for Anakin in some fanfics is a powerful element, and Anakin's potential sacrifice for Padme is also a recurring idea.
The theme of growth is also prevalent. Anakin, Padme, and Ahsoka all grow as individuals through their interactions with each other. For example, Anakin may learn more about self - control from Padme and Ahsoka. In addition, the theme of family - like relationships often appears. They act like a family, supporting and caring for one another.
Another theme could be their emotional bond without the sexual aspect. How they supported each other through difficult times, like Anakin's struggles with his Jedi training and Padme's role in the Senate. Their relationship was about more than just physical attraction, and fanfiction could delve deeper into their emotional connection and how it affected their decisions in the story.
One common theme is the struggle between love and duty. Anakin has his duties as a Jedi, but his love for Padme and their unborn child complicates things.
One common theme is betrayal. Anakin's actions, often related to his turn to the dark side, are seen as a betrayal of Obi - Wan's trust. This creates a deep sense of hurt in Obi - Wan.
Another theme is 'what - if' scenarios. Such as what if Anakin didn't turn to the Dark Side? How would their relationship have developed? This allows for a lot of creative storytelling.
One popular theme is the challenges they face as a couple expecting a child in a time of political unrest. Their relationship is already complex, and the pregnancy adds another layer of drama. For example, they might worry about the safety of their unborn child given the turmoil in the galaxy. Another theme could be how they prepare for the baby's arrival, like finding a safe place to raise the child away from the prying eyes of the Jedi Council or the Sith. It could also explore their hopes and dreams for their family's future.
In some fanfiction set in a more peaceful time, they might interact with a lot of tender moments. They could have picnics and long walks, just enjoying each other's company and having deep conversations about their future.
Obi - Wan Kenobi would be one. He's Anakin's master, and in the fanfiction, he might suspect something about their relationship and have to decide whether to support them or uphold the Jedi Code.
