Many fans might also be critical. They could feel that this goes against the essence of the characters as they know them from the original source material. However, others might appreciate the creativity of the fanfiction writer in taking the characters in a new and unexpected direction.
Some fans might be very disappointed. Jace and Clary are often seen as a beloved couple, so the idea of Jace cheating could go against their expectations and the image they have of the characters.
Clary might react with a sense of numbness at first. She's pregnant, which is a huge life change on its own, and then to find out Jace has cheated. She could withdraw into herself, not really knowing how to handle it. As time passes, she'll likely start to feel a deep sadness. She might cry a lot and feel like she's lost not only her relationship but also the future she had envisioned with Jace. However, her pregnancy could also give her the strength to be more independent and start thinking about building a new life for herself and the baby.
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.
One possible plotline could be Clary finding out about Jace's cheating and feeling extremely betrayed. She might then decide to leave him and try to build a new life for herself and her unborn child.
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.
Well, in fanfiction, their parenting style could be very inclusive. They've both had experiences of feeling like outsiders at times, so they'd make sure their child feels accepted no matter what. They'd also encourage their child to be independent and make their own choices, while still providing guidance based on their own experiences in the Shadowhunter world. They'd probably raise their child with a lot of stories from their own adventures, instilling a sense of adventure and courage in their offspring.
On the other hand, there could be fans who are interested in seeing the drama and conflict that would come from this. They might enjoy seeing how the characters would deal with such a complex and emotional situation. It could also open up new ways of exploring the personalities of Percy and Artemis.
On the other hand, some fans might be interested in seeing how the author develops the story from such a controversial starting point. They could be curious about how Pepper will respond and if there's a chance for redemption for Tony.
I'm not sure specifically. Fanfiction varies so much in quality. You could try searching on popular fanfiction platforms like Archive of Our Own. Just keep in mind that this kind of plot might deviate from the original story's essence and might not be to everyone's taste.
Well, some writers might do it to show the imperfections of the characters. In the original story, Jace and Clary's relationship seems quite idealized at times. By writing a scenario where Jace cheats, it could be a way to break that ideal and show that they are complex characters with flaws. Also, it could be a way to explore different relationship dynamics and how they could change over time. For example, how would it affect their friendship with other characters? How would they deal with the betrayal? There are many possible storylines that could stem from this one idea.
In such a fanfiction, perhaps Clary would have to face the challenges of pregnancy alone at first. She might struggle with her emotions, feeling abandoned by Jace.
