In this fanfic, the pregnancy could be a sign of hope for the Shadowhunter community. Clary and Jace, being two important figures, are now having a child. Their journey could involve seeking ancient knowledge from the Silent Brothers or the Iron Sisters about how to ensure the health of the baby, considering their unique genetic makeup as Shadowhunters. Along the way, they could strengthen their relationship even more as they face the challenges together.
One possible plot could be that Clary and Jace face a lot of social stigma. Their friends might be shocked and some might even turn their backs on them. They would have to deal with their families' reactions, which could range from disappointment to support. They'd also have to figure out how to continue their education while preparing for a baby.
The main characters are obviously Clary and Jace. Clary is a strong - willed and powerful young woman, and Jace is a skilled Shadowhunter. In the context of the pregnant fanfic, they are the couple expecting a baby.
In a fanfic, it could be that Jace realizes he can't live without Clary after seeing her in danger from a new threat. He has a moment of clarity where he understands that his love for her is more important than any of the issues that drove them apart. Clary, on the other hand, has always had a soft spot for Jace. When he starts to show his true feelings again, she is more than willing to give their relationship another chance.
Jace will probably face a lot of guilt. His cheating not only hurt Clary but also has implications for the unborn child. He might find himself ostracized by their friends who side with Clary. Also, his reputation within their community in the fanfiction world could be severely damaged. If he realizes his mistake and wants to make amends, he'll have a long and difficult road ahead to earn Clary's forgiveness and trust again.
Perhaps the fanfiction could focus on how their relationship evolves during the pregnancy. They might have more tender moments, but also arguments as the stress of the situation builds. For example, Jace could be overly protective, which Clary might find stifling at times. And they could also be preparing for the baby in a world full of demons and danger, like creating a magically protected nursery or finding special weapons to protect the baby when it arrives.
There's also 'Expecting the Unexpected'. In this fanfiction, it not only focuses on Clary's pregnancy but also how the Shadowhunter world around them reacts. It has some really interesting plot twists and character developments.
In this fanfiction, the development might involve Clary's friends trying to reunite her with Jace. They could see that Jace had his reasons for leaving and try to make Clary understand. On the other hand, Clary could be so hurt that she refuses to listen. Meanwhile, the pregnancy progresses, and Clary has to make decisions about the baby's future, like whether she wants to raise it alone or consider adoption. There could be a lot of emotional turmoil and growth for all the characters involved.
It would change in many ways. They would go from being carefree high school sweethearts to having a lot of responsibilities. There would be more arguments as the stress of the situation builds up. But at the same time, they would also have deeper moments of love and understanding as they face this huge life change together. Jace might become more overprotective of Clary, and Clary would need Jace's support both emotionally and physically.
In a 'Clary gets pregnant' fanfic, it could also explore how the pregnancy affects Clary's role in her world. If she's part of some sort of adventure or mission, she might have to step back or find new ways to contribute. There could be a lot of drama around protecting the unborn child from any threats in that fictional universe.
I really like 'Clary and Jace: A New Beginning'. This fanfic takes a different approach. It starts from a point where Clary and Jace are at a crossroads in their relationship. The author does an amazing job of building up their emotions and the slow - burn aspect of their re - connection is really engaging. There are also some interesting side - plots that add more depth to the story.
