One interesting plot idea could be Jace and Clary going on a secret mission within the City of Bones. They could discover a hidden chamber that holds the key to a long - forgotten Shadowhunter power. Another could be them facing a new and powerful demon that specifically targets their relationship, forcing them to rely on their bond more than ever.
Perhaps there could be a plot where Jace and Clary find a prophecy within the City of Bones that foretells their future. However, the prophecy is in a cryptic language and they have to seek the help of an old and wise Shadowhunter who has been living in seclusion in the City. As they work together to decipher it, their relationship deepens.
One key plot twist could be a revelation about their true family relations that's different from the original. Maybe Clary discovers she has a hidden power that Jace unknowingly has a connection to. Another could be that an enemy they thought was defeated in the original story resurfaces in a more powerful form in the fanfic.
The kiss could also be a part of a rescue mission. Jace is in danger, and Clary uses the power of their love, expressed through a kiss, to save him. She kisses him, and somehow, her love transfers energy or a healing power to him. This could show the depth of their bond and how their relationship is not just about romance but also about being there for each other in the most difficult situations.
Their relationship could develop through shared danger. For example, when they are in a fight against a horde of demons in the City of Bones, they rely on each other's skills. Jace's combat expertise and Clary's ability to see things others can't work in tandem, and this mutual dependence could bring them closer.
Clary could develop by becoming more independent in the fanfic. Instead of always relying on Jace, she starts to take the lead in certain situations. Jace's character might develop in terms of his relationship with Clary. He could learn to trust her completely, which was a struggle for him in the original. This could lead to him being more at ease and less brooding around her.
In a fanfiction, their kiss could be a turning point in their relationship. Maybe they had been denying their feelings for a long time, but this kiss shatters all the barriers. It could happen in a secret, magical place within the City of Bones. The setting would add to the allure of the moment. Clary might be the one to initiate the kiss, surprising Jace, and from that moment on, their relationship takes a new direction, filled with more love and understanding.
Perhaps they would encounter fanfiction that gives more backstory to their characters. In the City of Bones, there are a lot of mysteries about their pasts. Fanfiction writers might have come up with some really interesting theories and stories about their origins. Clary and Jace could gain new insights into their own identities by reading these fan - created stories. It could also be a way for them to connect more deeply with the fan community that loves their story so much.
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.
One scenario could be that their kiss is a moment of realization. In the midst of all the chaos in the City of Bones, their kiss is like a sudden burst of clarity. They've been through so much together, and this kiss is the culmination of all the unspoken feelings. It could be a very passionate kiss, filled with all the pent - up emotions from their adventures and the danger they've faced.
They could start by looking at some well - known fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfiction for various fandoms, including the City of Bones. There are likely to be many high - quality stories there, sorted by different categories such as genre, rating, and relationship focus.
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.
