The character development of both Clary and Sebastian is important. Writers usually focus on how they interact with each other, how Clary deals with Sebastian's darker side and vice versa. For example, in some fanfictions, Clary tries to find the good in Sebastian, which is a big part of their relationship exploration.
One key element is the exploration of their forbidden relationship. Since they have a rather complex and somewhat taboo connection in the original lore, fanfiction often dives deep into that.
One key theme could be the complex relationship between Sebastian and Clary as siblings in this fanfiction. It might explore their different personalities and how they interact within the unique context of the story. Another theme could be the use of 'lemon' elements, which often imply a more mature or romantic undertone, and how that plays into their relationship. Maybe it also delves into the idea of family bonds being tested or transformed by their circumstances.
One key element could be the unique setting related to the lemon. It might be a lemon - scented magical place or an object that has lemon - like features.

One great piece of Clary and Sebastian fanfiction is 'The Unlikely Bond'. It delves into their complex relationship in a very engaging way, exploring their characters' depths beyond what's shown in the original work.
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.
The 'lemon' element makes the story more intense. It adds a sexual undertone that can heighten the emotions between Sebastian and Clary. It might show a side of their relationship that is more primal and less controlled by the usual social norms for siblings. For example, it can make their interactions more charged and full of tension.
The theme of sacrifice is also quite common. They might have to sacrifice their own desires, like their freedom or their previous life goals, for the sake of the baby. Also, the theme of identity. With the pregnancy, they both have to re - evaluate who they are. Clary is no longer just a young shadowhunter, but a soon - to - be mother. Sebastian has to figure out if he can be a father and what kind of father he wants to be, considering his dark past.
One possible plot could be a twist where Sebastian has some sort of redemption arc. Maybe he discovers that Clary is pregnant and realizes he wants to change for the sake of the unborn child. He starts to fight against his dark side and tries to protect Clary and the baby from the threats in their world.
In rated M fanfiction, Sebastian and Clary often represent complex and intense relationships. Rated M usually implies mature themes. Their characters might be involved in more adult - like situations, such as deep emotional turmoil, dangerous adventures together, or complex power dynamics. For example, their relationship could be explored in the context of a darker, more mature version of the story's universe, with themes like forbidden love or power struggles.
One common theme is the exploration of their complex relationship. Given their rather dark and twisted connection in the original story, fanfictions often delve deeper into how they interact with each other, whether it's Sebastian's attempts to manipulate Clary or Clary's struggle against his influence.
Some fanfictions might have a plot where the kiss is a strategic move. For example, Clary might kiss Sebastian as a way to deceive him or gain some advantage in a battle or a power struggle within the Shadowhunter world. This adds an element of intrigue and manipulation to the story.
