Well, one interesting plot could be Clary slowly regaining her memories through a series of magical encounters. Maybe she finds an old object that triggers flashes of her past. Another could be that her friends play a crucial role in helping her get her memories back, like they take her to special places related to her past. And a third possibility is that there's some sort of enemy who is trying to stop her from getting her memories back, which adds a lot of suspense to the story.
One plot could be that Clary's memories are locked away in a magical realm. She has to go on a dangerous quest to this realm to retrieve them. Along the way, she meets different creatures and overcomes various obstacles. Another interesting idea is that her memories are scattered among different people. So she has to travel around and meet these people, and each encounter gives her back a part of her memory. Also, it could be that her memories are being held hostage by a dark force, and she has to battle this force to get them back.
In some fanfictions, Clary might get her memories back in a dream. She dreams of her past life and relationships, and when she wakes up, she starts to remember bits and pieces. Or perhaps there's a new character introduced who has the power to restore memories, but at a cost. Clary has to make a difficult decision to fully regain her memories. Another plot could be that Clary's memories are tied to a prophecy, and as she gets them back, she discovers her true role in a much larger scheme.
Clary is the central figure. Valentine might also be involved in some fanfictions, either as an obstacle trying to prevent Clary from getting her memories back because he doesn't want her to discover certain secrets, or in a more complex way where his past actions are somehow related to the loss of her memories in the first place. And of course, the Lightwood family members are likely to be involved, given their importance in Clary's life and the Shadowhunter community.
Well, sometimes in these fanfictions, there's a plot where Clary gets jealous over a prophetic vision. Say, she has a vision of Jace being with another girl in the future. This makes her extremely jealous and she tries to change the future. Or it could be that a new girl arrives in the Institute and she has some special connection with Jace, like they share a rare power. Clary then gets jealous as she fears Jace might be drawn to this girl because of their shared ability.
One possible plot could be that Clary gets drunk and ends up confessing her hidden feelings to someone she has a crush on.
In this type of fanfiction, a great plot can be Naruto going back and influencing the Third Hokage's decisions. For example, he could convince the Hokage to be more open - minded about new techniques and alliances. He might also focus on improving the living conditions in the village at an earlier stage. By doing so, he could potentially change the future of the entire Hidden Leaf Village and the shinobi world in general.
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.
One interesting plot could be their journey through the pregnancy while still dealing with the Shadowhunter world's threats. They might have to protect their unborn child from demons or other dark forces. Another could be how their friends and family react to the news, with some being overjoyed and others worried about the future of the new family in such a dangerous world.
Well, a common plot is that they discover some ancient prophecy or law that seems to be the main reason for their love being forbidden. So they embark on a journey to find a way to change or break this law. During this journey, they face many dangerous creatures and difficult situations. And as they grow closer through these challenges, their love becomes even stronger, defying all the odds.
One possible plot twist could be that Sebastian's true motives for getting Clary pregnant are revealed to be part of a larger, darker scheme. Maybe he plans to use the baby for some sort of power - play within the Shadowhunter world.
One interesting plot could be about a pony's adventure where the 'paws on her back' situation is part of a special power transfer. For example, an ancient magic might be passed through this physical contact, leading the pony to gain new abilities and embark on a journey to save the pony land from an unknown threat.
Another plot could be that the girlfriend is from a rival hunter family. At first, there's tension between them because of their families' differences. But as they get to know each other better, they fall in love and try to bridge the gap between their families. This would be a story full of conflict and resolution.
