Perhaps they find out they're pregnant unexpectedly. Stiles starts making all these plans for their future as a family right away. Lydia is more cautious, thinking about how this will change their lives completely. Their friends could also play a big role, some being super supportive while others might be skeptical. And they could have to deal with family reactions, like Stiles' dad being really excited and Lydia's parents having mixed feelings.
A plot could involve them going on a journey to find a way to ensure a safe pregnancy. Since they're from a world with supernatural elements, there could be threats to the baby that are not normal. They might seek help from an old wise character who tells them about certain precautions they need to take. Along the way, they grow closer as a couple, learning more about each other's fears and hopes for their future family.
Well, one possibility is that they face challenges in their relationship due to the unexpected pregnancy. Maybe their families have different reactions, some supportive and some not. This could lead to them having to make tough decisions about their future together and how to raise the baby.
One idea could be that Lydia discovers she's pregnant and has to deal with the reactions of her friends and family. Maybe Stiles is the father and they have to figure out how to handle this new situation while also dealing with the supernatural threats in their town.
Perhaps in the fanfiction, Lydia is pregnant in a post - apocalyptic world. She has to find ways to protect herself and her unborn baby from various threats. This could involve teaming up with unexpected allies and facing difficult moral choices along the way.
Their relationship would transform in many ways. They'd have to start thinking as a unit, not just as individuals. Stiles would become more responsible and Lydia would see a new side of him. She, in turn, would become more vulnerable in front of him, sharing her insecurities about motherhood. There would be a deeper level of trust as they share the journey of pregnancy. They'd also start to plan their future more concretely, which would involve a lot of compromise and understanding, thus changing their relationship dynamics for the better.
Maybe there's a mystery surrounding the pregnancy. Since they are in a world full of the supernatural, the baby could have some special powers even before birth. Some of the other characters like Scott and Stiles might suspect that there's something unusual about the pregnancy. They could try to investigate, which causes some tension between them and Lydia and Parrish, who just want to enjoy the pregnancy without all the scrutiny. But in the end, they all come together when they realize they need to protect the baby from some external supernatural threat.
One idea could be that they face challenges from their families who are initially not supportive of their relationship now that Lydia is pregnant. Another could be that they discover some sort of supernatural complication related to the pregnancy. For example, the baby might have special powers that start to manifest during the pregnancy and they have to figure out how to deal with it.
One possible plot idea could be about Lydia's journey through pregnancy. Maybe she discovers she's pregnant unexpectedly and has to deal with the reactions of her family and friends. For example, her parents might be disappointed at first if she's young, but then gradually come around to support her. Another aspect could be how she copes with the physical and emotional changes. She might find solace in a new friendship or an old acquaintance who has also been through pregnancy.
One plot idea could be the challenges she faces in hiding her pregnancy from certain characters in the fanfic's world. Maybe there are those who would use it against her or the group she's associated with.
Well, the story could focus on Stiles' relationship with the baby's father (assuming there is one). There could be a lot of drama if the father is not ready or if there are some secrets between them. Stiles might also struggle with the idea of becoming a parent so young and how it will change his future plans. He could start thinking about his own family and how his parents' experiences might influence his own journey into parenthood.
One idea could be that they face unexpected challenges during the pregnancy. For example, Derek discovers a family curse that might affect the baby, and they have to find a way to break it. Another could be that Lydia has premonitions about the future of their child, which leads them on a journey to protect the unborn baby from a hidden danger.
