Maybe in the fanfiction, the father of the baby is a mystery. Clary has to deal with the speculation and rumors around who the father could be while also taking care of her little one. It could add a lot of drama to the story as she might face accusations or unwanted attention.
It's possible that the story is about Clary's journey of self - discovery through motherhood. Despite the secrecy, she could be learning a great deal about herself, her strength, and her ability to love unconditionally. The baby could also have some special powers or abilities that Clary has to protect it from those who might want to use it for their own gain. This would create a whole new set of challenges and adventures for Clary.
One possible plot could be Clary adjusting to motherhood while still dealing with her shadowhunter duties. Maybe she has to protect the baby from demons who are after it because of its special powers.
Well, maybe the story could start with Stiles finding out about the baby unexpectedly. For example, an old acquaintance shows up with the baby and reveals that it's his. Then he has to deal with the shock and start learning how to be a father while still keeping it a secret from his friends and family.
Well, perhaps the story could be about Sakura trying to hide the existence of her baby from society due to some kind of stigma or danger. Maybe she's a young and unwed mother in a very traditional setting.
Maybe the story could be about Hermione trying to protect the baby from dark forces in the wizarding world while keeping its existence a secret. She might have to face challenges alone without the support of her friends at first.
Jace could be the father. Since they have a strong connection in the original story, it would make sense for him to be the father in the fanfiction.
One possible plot could be that Kratos discovers he has a baby in a very unexpected way. Maybe he finds the baby left at his doorstep. He initially has no idea how to take care of it but as time passes, he starts to learn and forms a strong bond with the baby. He protects the baby from all the threats in his dangerous world.
Maybe Clementine discovers she's pregnant unexpectedly. She then has to deal with the physical and emotional changes during pregnancy. After giving birth, she has to protect her baby from various threats, both human and non - human. She might train her baby from a very young age to be strong and survive in their difficult circumstances.
Well, perhaps in the fanfiction, Spiderman saves a woman who later turns out to be pregnant with his child. He doesn't know about it until she shows up at his doorstep with the baby. Spiderman then has to figure out how to take care of the baby. He might start using his web - slinging skills in new ways, like creating a safe web - hammock for the baby to sleep in while he's on patrol, and he has to deal with the reactions of his friends and allies, like Mary Jane or Ned.
One possible plot could be that Stiles discovers he has a baby unexpectedly. Maybe an old fling left a baby on his doorstep. He then has to learn how to be a father while still dealing with his normal life, like school and his friends. He might struggle at first with things like changing diapers and getting up in the middle of the night, but with the support of his friends, he slowly gets the hang of it.
Jace would likely be an important character. Given his relationship with Clary, he would probably be deeply affected by the news of the baby. His reaction could range from shock to protectiveness.
