One possible fanfic could be about Obi - Wan's conflicted feelings between Satine and Siri. Maybe it shows how his Jedi duties and his relationships with these two important women in his life intersect. For example, a scenario where Satine's political situation in Mandalore forces Obi - Wan to make difficult choices, all while Siri, as a fellow Jedi, has her own take on the matter and how Obi - Wan should handle it.
In Clone Wars, Obi - Wan Kenobi's character is often focused on his Jedi duties. However, his interactions with Duchess Satine Kryze are often cited as having a love - like quality. Their past together and the way they still interacted during the Clone Wars, with Obi - Wan sometimes going out of his way to protect her, suggest that there was a special connection between them that could be considered part of a love story.
Perhaps he has some personal issues to deal with. Maybe he has received some news about his family (even though Jedi are not supposed to be attached, but they still have family ties in some sense). Or he could be having some doubts about the Jedi Order's actions in the war and needs time away to think.
The most prominent aspect of a possible love story for Obi - Wan in Clone Wars is his relationship with Satine Kryze. They met when Obi - Wan was younger. Satine was a pacifist leader. Their values sometimes clashed but their personal connection was strong. Even though Obi - Wan was a Jedi, he couldn't completely forget about her. When she was in danger during Clone Wars, he was very concerned and tried to protect her.
If Obi - Wan asks for leave time, it could also lead to some character development for him. He's always so busy with the Clone Wars that he rarely has time for himself. During his leave, he might have some self - discovery. He could question his role in the war, his relationship with the Force, or even his friendship with Anakin. And this could change his approach when he returns to the war.
One common theme is his relationship with Anakin. Writers often explore the mentorship aspect more deeply, showing their bond and how it evolved during the Clone Wars. Another theme is Obi - Wan's solo adventures that might not be shown in the original series, like undercover missions or his interactions with other Jedi.
One plot idea could be a time - travel scenario. Maybe a Sith artifact causes Obi - Wan, Satine, and Siri to be sent back in time to a crucial moment in Mandalore's history. They have to use their knowledge of the future and Jedi skills to prevent a catastrophe that would change the course of the Clone Wars. During this, Satine might see a different side of Obi - Wan's past, and Siri could learn more about their relationship.
Often, Obi - Wan uses his mastery of the Force. He might use a Force - push to overpower his guards when they least expect it and then make a run for it. He could also use a mind trick on a high - ranking captor to order his release.
