In a fanfic where they go to the future, they might be shocked by the advanced technology. Maybe they see flying cars and buildings that touch the sky. Anakin could be intrigued by new forms of lightsaber combat, if they still exist. Padme might be amazed by the new political systems and how society has evolved in terms of equality.
Well, for Anakin, his first reaction in the future could be one of confusion and a bit of awe. He'd see things he couldn't even have imagined in his wildest dreams. His mechanical parts might start acting up due to the different technology around. Obi - Wan would be like a sponge, soaking up all the new information. He'd be comparing this new world to the Jedi teachings and the past he knew. Padme would be fascinated by the new architecture and the way people interact. She'd start asking questions right away, trying to piece together how this future society came to be. And all three of them would be a bit disoriented at first, but their different personalities would drive them to explore and understand the future in their own ways.
As Padme is pregnant, Anakin may start to think more about his future and his place in the galaxy. This could lead to deeper conversations between them about their values and what they want for their family. Their relationship will grow as they both adjust to the idea of becoming parents and all the responsibilities that come with it. They'll have to support each other through the physical and emotional changes that Padme is going through, and also deal with the external threats to their family.
In many fanfictions, Obi - Wan might use his deep knowledge of the Force. He could reach out to Anakin through a Force - bond, calming his inner turmoil and guiding him away from the dark side. For example, he might remind Anakin of their past together, their training, and the values they once held dear.
One common theme is loyalty. Both Obi - Wan and Padme are loyal to the Republic, and in fanfics, this loyalty often plays a big part in their relationship. Another theme is sacrifice. They are both characters who are willing to sacrifice for the greater good, and this is often explored in how they interact with each other.
Another theme is the struggle between duty and personal feelings. Obi - Wan is a Jedi with strict duties, and Padme is a senator with her own responsibilities. Fanfictions like to play with how their personal feelings for each other might conflict with what they are supposed to do. For example, in some stories, Obi - Wan has to choose between following the Jedi Code and helping Padme.
One great 'obi wan kenobi and padme fanfiction' is 'The Unspoken Alliance'. It delves into their complex relationship within the Star Wars universe in a very engaging way.
In fanfiction, there's no set rule. It's a realm of creativity. There could be a fanfiction where Obi - Wan is related to Padme's father through a prophecy or a magical force - related event. Or perhaps in a parallel universe - type fanfiction, their relation is part of a major plot twist. So, simply put, it's possible in the wild world of fanfiction.
Maybe the Force itself could be an antagonist in a sense. The light side of the Force would be trying to pull Obi - Wan back from the dark side. And the natural balance of the Force that doesn't want too much dark side influence could be working against Anakin's plan to turn Obi - Wan. So the Force, in its own way, could be the main antagonist.
