Gwen could also take care of Ben. As his cousin, she would be worried about him. She might use her magic to try and ease his symptoms or find a cure. She would probably make him some soup and keep him company while he's sick.
Well, it could be that his friends have to step up and protect the city while he's sick. Gwen and Kevin might have to deal with villains on their own, and they could struggle without Ben's usual power. Also, Ben might be really frustrated because he can't use his powers as he normally does when he's ill.
The first thing that might happen is chaos among those who know Ben. His family would be worried sick. If the kidnappers are villains who know about the Omnitrix, they could try to force Ben to unlock all its secrets. But Ben won't give in easily. He'll fight back using whatever means he can, even if he's restrained.
It could be Vilgax. He's one of Ben's most powerful enemies. Vilgax is always looking for ways to defeat Ben, and he might come up with a new and devious plan to hurt him. Maybe he teams up with other villains to ambush Ben when he's least expecting it.
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.
One possible scenario could be that Ben gets hurt during a fight with a powerful alien. Maybe he underestimates the enemy's strength and gets severely injured while trying to protect someone. Another could be an accident while testing out a new alien form. The transformation might go wrong and cause him physical harm.
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.
Sango could also take care of Kagome. As a strong and kind - hearted woman, she would know how to nurse Kagome back to health. She might use her knowledge of herbs and remedies to make Kagome feel better. Plus, she would offer emotional support to Kagome during her illness.
In the 'Boruto Gets Sick' fanfiction, Boruto might experience various symptoms like a high fever, weakness, and coughing. His friends and family would likely be worried about him. They would probably take care of him, bring him medicine and try to make him comfortable.
