One possible cause could be improper grammar or spelling that disrupts the flow, like incorrect verb tenses. Another might be the use of cliched or overused plot elements which 'infect' the originality of the fanfic.
Perhaps the fanfic has an 'infection' because of a lack of proper research. For example, if the setting of the fanfic is a real - life location or a specific time period, inaccuracies can make it seem less believable. Also, if the dialogue doesn't match the characters' personalities or the overall tone of the story, it can be like an 'infection' that weakens the fanfic.
Well, perhaps in the fanfic, Amy Fleming gets an infection after helping a sick animal. She starts to experience symptoms like fatigue and fever. The story could revolve around her struggle to keep up with her daily tasks at Heartland. Her family notices something is wrong, but she brushes it off at first. As the infection gets worse, she finally has to accept help and they all work together to find a treatment.
She could start by proofreading for grammar and spelling mistakes.
Her family at Heartland could help her. Her grandfather Jack, with his years of experience, might know some home remedies or old - fashioned cures. Her sister Lou could use her business connections to find the best medical help available. And her mother Marion, even if just in spirit, could give her the strength to fight the infection.
It could be due to an injury like a sprain from falling off a horse. Horses are a big part of Amy Fleming's world, and accidents can happen easily.
It could be due to an injury like a sprain from a fall while riding a horse, which is common in her character's activities. Maybe she overexerted herself during a long ride.
One possible cause could be an allergic reaction. Maybe she's exposed to a new type of pollen or a strange animal in the story. For example, if she visits a new place with rare plants, the pollen might trigger her breathing problems.
One possible plot could be that Amy Fleming starts having vivid flashbacks of a past trauma. These memories start to affect her daily life, and she has to find a way to deal with them. Maybe she seeks help from a friend or a professional.
Maybe she's injured. In many fanfics, characters can get hurt in various ways, like a fall from a horse or an accident, which could lead to her being unable to move.
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.
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.
