In this type of fanfiction, a great plot could revolve around Jane's pregnancy and how it changes her perspective on life. Maybe she starts to question her career choices and whether she wants to continue in the dangerous world of detective work. There could also be a lot of emotional moments with her family and friends. For example, her mother could be overjoyed but also worried. And Isles could be there every step of the way, providing support and sometimes comical relief as she tries to understand all the new things that come with pregnancy like baby showers and choosing nursery colors.
One plot idea could be that Jane is kidnapped by a criminal she put away in the past who has escaped and is seeking revenge. Her partner Isles has to race against time to find the clues Jane left behind before it's too late. Another could be that a serial kidnapper targets Jane because of her detective skills, thinking she'll be a worthy challenge. Isles then uses her medical knowledge and understanding of Jane to figure out where she might be held.
One idea could be that the baby has an unexpected medical condition which brings out the protective and detective sides of Rizzoli and Isles as they search for answers. Another could be that the baby has a special talent that starts to show at a very young age, like an extraordinary memory, and they have to figure out how to nurture it while keeping the baby safe. Maybe the baby gets kidnapped, and Rizzoli and Isles have to use all their skills to get the baby back.
Maybe a fanfiction where they have to solve a crime that hits a bit too close to home for Isles. Rizzoli has to be extra supportive, and in the process, they discover new things about each other's pasts that they hadn't known before. This could add more depth to their relationship.
Isles would be an obvious great supporting character. She could offer medical advice to Jane during her pregnancy, as well as be there for her emotionally. Maura's scientific mind could also come in handy when it comes to things like baby - related research or understanding the pregnancy process better.
One common theme is friendship. Fanfictions often explore the deep and unique friendship between Jane and Maura. Another theme is mystery - solving, as they are detectives in the original show, so many fanfictions continue with that aspect. Also, the theme of loyalty is quite prevalent, showing how loyal they are to each other in different situations.
There could be a fanfiction where Maura Isles is pregnant and she and Jane have to deal with the challenges in their work environment while also preparing for the baby. Maybe they face some difficulties with their colleagues' reactions, but they support each other throughout.
One idea could be that a case in Boston (Rizzoli and Isles' territory) has connections to a military - related case that NCIS is investigating. For example, a murder victim in Boston turns out to be a former Navy officer, and both teams have to work together to figure out the motive and the killer. They might clash at first due to different investigation styles, but then gradually learn from each other.
One great fanfiction might be one where Maura and Jane have a big misunderstanding but then slowly start to rebuild their friendship. For example, a story could be about Maura accidentally saying something hurtful during a case, and Jane distances herself. But as the story progresses, they realize how much they need each other in solving crimes and in their personal lives.
Another possible fanfiction could focus on their friendship in a different setting, like they are both in a foreign country for a conference and end up getting involved in a local mystery. This would show how their skills and friendship work in a completely new environment.
Well, 'Shared Secrets' is a fanfiction that's quite popular. It shows Jane and Maura sharing secrets that they've never told anyone else, strengthening their bond even more. 'Parallel Lives' is also good. It creates a scenario where Jane and Maura have to live different lives for a while, but still find their way back to each other. And 'The Unbreakable Link' emphasizes how their relationship is unbreakable no matter what challenges they face.
