There could be many interesting fanfiction plots around Dawson being pregnant in 'Chicago Fire'. Maybe it could explore how she balances her job at the firehouse with her pregnancy, the support she gets from her colleagues, and the changes it brings to her relationships.
One possible scenario in such a fanfiction could be that Dawson gets hurt during a rescue operation. Maybe she is trapped under some debris while trying to save a victim in a burning building. Her fellow firefighters then have to race against time to get her out safely.
Another theme is professional growth. Fanfics might show how they learn from each other and improve their skills as firefighters. For example, Casey might teach Dawson a new technique for handling a certain type of fire, and Dawson could share her insights on dealing with victims.
One storyline could be Dawson having to deal with morning sickness while on duty. She might try to hide it from her colleagues at first but then they find out and offer their support.
The plot might involve Dawson being initially scared to tell Casey about the pregnancy. Once she does, Casey has to deal with his own insecurities about being a father. As the pregnancy progresses, they could face criticism from some people in their lives who think they're too young or not ready. But they stay strong together, with Dawson relying on the support of the female firefighters and Casey getting advice from his male colleagues. In the end, they look forward to the birth of their baby with excitement and a bit of nervousness.
Their relationship will likely become more intimate. Casey will be more protective of Dawson, and they'll have to communicate more about their future plans. They'll be more focused on each other and the baby rather than just their own individual lives.
She could be hurt while responding to a chemical fire. The chemicals could cause burns or respiratory problems for her. Her team would be desperate to get her the proper medical treatment, and there could be a struggle to find the right antidote or treatment method.
One great fanfic could be about Casey and Dawson working together on a particularly difficult rescue mission. They face many challenges and in the process, their bond deepens. Their teamwork and mutual respect shine through as they save lives.
The key characters would surely include Dawson. Her partner at work, who would be directly affected by her getting hurt. Platt from the police department could also be a key character if she gets involved in some way, like in the investigation of what caused Dawson's injury. And Hermann, who is always there for his colleagues at the firehouse, would be another important one. He might be the one to keep everyone's spirits up during Dawson's recovery.
In a fanfic where Dawson gets hurt in Chicago Fire, it could start with a routine call that turns dangerous. Let's say there's a gas leak explosion and Dawson is caught in the blast. Her colleagues would be in a state of shock and panic. They'd quickly try to assess her injuries and get her to the hospital. At the hospital, there could be a waiting game as they all hope for her recovery. Her injury might also make her question her future in the firefighting profession. Some of her friends might encourage her to keep going while others might be more hesitant, thinking she's been through enough. This conflict among her friends and her own internal struggle could form the basis of the fanfic.
