The plot could involve Clary's search for the baby's father if he's not initially involved. She might face challenges like him denying the paternity or him being in a difficult situation himself. As she tries to get him involved, she could learn more about his family and background, which could lead to unexpected twists in the story, like uncovering family secrets or feuds that now affect their situation.
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.
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.
The theme of future and responsibility is also often explored. Clary has to think about not only her own future but also the future of the baby. This includes things like where she'll live, how she'll raise the child, and how it will impact her goals and dreams. For example, if she was in the middle of some important mission or study, the pregnancy will force her to reevaluate all those aspects of her life.
One common theme could be the challenges they face in high school while dealing with the pregnancy. Another might be the reactions of their friends and family. For example, their friends could be either very supportive or judgmental.
Alec might also play an important role as a supporting character. He could be the voice of reason for Jace, making sure he doesn't make any hasty decisions. And Luke would surely be involved. As someone who has always been like a father figure to Clary, he would offer his wisdom and support, and maybe even help them figure out the financial aspects of having a baby so young.
One possible consequence could be social isolation. Her peers might judge her harshly, leading to her being ostracized at school. Also, her academic performance would likely be affected as she'd have to deal with the physical and emotional stress of pregnancy.
The consequence might be a change in her future plans. College or career aspirations could be put on hold. Financially, it would be a huge burden without proper support. She may have to rely on her family or seek other forms of assistance. Also, her relationship with the baby's father could become strained due to the stress and responsibilities.
On the other hand, there could be a glimmer of hope in their relationship. Maybe through the shared experience of the pregnancy, they start to see the good in each other. Clary might see a side of Sebastian that she never knew existed, and Sebastian might start to have real feelings for Clary and the baby, leading to a more complex and evolving relationship.
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.
