In this fanfiction, the two main characters are Jonathan and Clary. Jonathan's character might be developed further as he adjusts to the idea of being a father. He may have to make sacrifices and grow in ways he hadn't expected. Clary, as the pregnant one, is likely to be the focus of much of the story's emotional core. She'll be dealing with hormonal changes, fears about motherhood, and the added pressure of having a baby in a world filled with danger and magic.
Clary's family has always been protective of her. So, they would likely be very cautious about this pregnancy. Her father figure, if he's still around, might want to ensure that Jonathan is worthy of being in Clary's and the baby's life. They might put Jonathan through a series of tests or challenges to prove his commitment. On Jonathan's family side, if they are part of a more villainous group, they could see the baby as a tool for their own evil plans. Or, if there are some good - hearted members, they might try to guide Jonathan and Clary towards a more positive future together.
Well, perhaps there's a plot where they discover some ancient prophecy related to their baby during the pregnancy. And they spend the whole time trying to figure out what it means and how to ensure their child's safety according to the prophecy. They might seek help from different factions in their world, like the Shadowhunters or Downworlders.
One possibility is that they would face a lot of challenges. Their families might have mixed reactions. Some may be supportive, while others could be against it due to various reasons like age or their family's standing in the fictional world. They would also need to think about their future, like where they will live and how they will support the baby.
Alec and Isabelle could be important characters too. As part of the shadowhunter group, they have the skills and resources to track down Jonathan. They could be the ones who gather intelligence on Jonathan's whereabouts and plan the rescue strategy, while also dealing with their own personal issues and relationships within the group.
Their relationship would likely become more intense. There would be a new level of intimacy not just physically but also emotionally. They now have a shared future in the form of the baby, so they would need to rely on each other more.
Fanfiction might be a way for Jonathan and Clary to express their own creativity vicariously. Even if they are not writing it themselves, by reading and loving different fanfiction stories, they are engaging with the creativity of other fans. It's like they are part of a larger creative process. Additionally, it could be a form of emotional investment. They might be so attached to the characters in the original story that they want to see more of their lives and adventures, and fanfiction provides that in abundance.
