Maybe a young girl from the nearby town who is interested in the ranch life. She could visit the ranch and help Amy with some of the lighter tasks, and their conversations could be a source of comfort for Amy during her tired days. For example, they could talk about dreams and hopes which would give Amy a boost. The girl could also learn a lot from Amy about taking care of animals and the land.
There could be a traveling vet. He comes to the ranch to check on the animals. He notices how tired Amy is and offers his help not just with the animals but also gives her some tips on self - care. He could be an interesting character as he has stories from all over about different animals and their owners, which could both distract Amy from her tiredness and inspire her in her work on the ranch.
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.
One possible plot could be that Amy Fleming has been working hard on the ranch all day. She's physically and mentally tired. Maybe she gets some unexpected help from a new friend in the fanfic, and they bond over taking care of the horses. This new friendship gives her the energy to keep going.
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.
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.
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.
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.
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.
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.
A jealous rival at the ranch could be a likely suspect. Maybe someone who is envious of Amy's skills with horses or her popularity at the ranch. Another suspect could be a disgruntled former employee who was fired by Amy's family and holds a grudge. It could also be someone from a competing ranch who wants to disrupt the Fleming ranch's operations by harming Amy.
Her best friend could be her helper. This person would know Amy well and could anticipate her needs. For example, they could bring her favorite foods and keep her company when she's feeling lonely or bored.
