One common plot could be her fellow Jedi or friends trying to find a cure. For example, Anakin might search for rare herbs to heal her. Another plot could involve her having a vision during her illness that guides her or her friends on a future mission. Also, it could be about how she copes with being sick while still feeling the need to contribute to the Jedi Order's activities.
Well, one possibility could be that her friends in the Star Wars universe like Anakin or Rex would be worried about her. They might try to find a cure or a way to make her feel better. Maybe they would search for some rare herbs or medical technology.
Ahsoka's own species' healers, if there are any in the Star Wars lore that could be introduced, would be an amazing addition. They could bring in unique healing methods. Additionally, characters like Aayla Secura or Shaak Ti could be involved. They are strong female Jedi who could offer support and sisterly advice to Ahsoka. And of course, some of the clone troopers under her command could be included to show their loyalty and concern for their commander.
Padmé could also be involved. She is known for her compassion. She might use her resources to get the best medical help for Ahsoka. She could bring in the best doctors in the galaxy or some special remedies from Naboo.
Perhaps she had an argument with a fellow Jedi. Disagreements among Jedi can be very upsetting as they are supposed to be in harmony. If she felt that she was wrongly accused or not understood, it would make her upset.
It might be that in this fanfiction, Ahsoka gets cuts in a more accidental way. For example, she's exploring an old, dangerous place and gets cut by some sharp debris. The story could then focus on her survival skills and her inner strength as she tries to patch herself up and continue her journey.
I'm not sure who the specific author of this fanfiction is. There are so many fanfiction writers out there, and without more context or research on dedicated fanfiction platforms, it's difficult to determine.
In addition to his family and friends, the medical ninja in the village would be involved. They would be the ones to accurately diagnose Boruto's condition. Shizune, for example, could come and check on him, using her vast medical knowledge. And the other young medical ninjas might learn from this case, as Boruto's illness could be something new or unusual, so they would be eager to assist and gain experience while taking care of him.
Seth could be the one to help her. As her brother, he would be very concerned and might use his own knowledge of Fablehaven and its secrets to try and find a cure. He could also enlist the help of some of the friendly magical creatures they've befriended, like the fairies or the satyrs.
His teammates, Sasuke and Sakura, would surely be involved. Sasuke, although he may not show it as much, still cares about Naruto. He would keep an eye on Naruto's condition, and if there was any sign of danger, he would be ready to protect him. Sakura would be more hands - on with the medical care, checking his temperature, giving him medicine, and making sure he rests properly.
