Perhaps a mentor figure in her life, like an older person she respects. This person could have more life experience and be very worried about her. They would use their wisdom and authority to try and make Amy Fleming listen and take the necessary steps to get better.
Her friends could be the ones. Maybe her closest friends who know her well and see that she's not acting in her own best interests. They might try different tactics, like joking around to ease the tension while also trying to get her to listen to reason about her illness.
It could be her family members. For example, her parents or siblings might be very concerned about her health and constantly trying to persuade her to take care of herself. They would be the ones using their love and concern to try and break through her stubbornness.
Well, perhaps the plot could revolve around Amy Fleming being sick with some kind of illness, maybe a fever or a more serious disease. And her not listening could be related to her being stubborn about getting proper treatment. For example, she might be so focused on taking care of her animals or something else she loves that she ignores her own health needs.
Definitely Ty Borden. He and Amy have a special relationship, so he would be deeply concerned about her illness. He could be the one running errands, getting medicine and making sure she has everything she needs. Georgie could also be a main character. She could be helping Lou with the ranch work and also spending time with Amy, telling her stories to keep her spirits up. And then there's Spartan, Amy's horse. Spartan could be acting strangely because he senses something is wrong with Amy, and his behavior could be a part of the story as well.
Amy Fleming and Ty are likely characters from a particular series or fandom. They could be characters who have a relationship, perhaps friends or more than friends. Without more context, it's hard to say exactly who they are in the grand scheme of things, but they must be important to the story if Amy is yelling for Ty.
There might be a mysterious stranger. This person could be passing by when they hear Amy Fleming's screams for help. They could have some special skills or knowledge that can assist her in whatever situation she's in. Another possible character could be an authority figure like a sheriff or a teacher, depending on the setting of the fanfic, who has the power to protect her.
One possible story could be that Amy Fleming uses her skills and knowledge (assuming she has some relevant skills in the original context) to take care of the sick little kid. She might bring the kid some warm soup, read stories to comfort the child, and call a doctor if needed.
Maybe there could be a neighbor who stops by. This neighbor could be an elderly person who has some old - fashioned remedies and shares stories with Amy while she's sick at home.
Her best friend could be a main character. This friend might be constantly by her side, bringing her schoolwork so she doesn't fall behind and also sharing the latest gossip from school or the stables.
In the fanfic, her character could be shown in a more introspective light. Since she's confined to her bed with the flu, she has time to think about her life, her relationships, and her future. She might have flashbacks to important moments in her past and realize things about herself that she hadn't before. This could lead to some character growth once she recovers from the flu.
The neighbors could also play an important role. They might be the ones who notice something is wrong first and inform Amy. Later, they could bring over home - made soups or offer to babysit other children if Amy has more than one, so she can focus on the sick child.
Lou Fleming could also play a major role. As Amy's sister, she could be the one taking charge of the household while Amy is sick, making sure everything runs smoothly.
