Another option is a group of demons who have a vendetta against Clary or the shadowhunters in general. They might use torture as a way to break her spirit and gain information about the shadowhunters' defenses.
One possible plotline could be Clary's friends finding out about her being tortured and launching a rescue mission. They might face many obstacles on their way to save her, like fighting off the torturers' guards.
Simon might be in a bit of a panic. Since he's her friend and also not as used to the dangerous situations as the other Shadowhunters. He'd try to do whatever he can to help, like getting help from more experienced Shadowhunters or trying to comfort Clary while she's in pain.
Appropriateness is subjective to some extent. While some people might be interested in exploring the darker sides of a character like in 't challa gets tortured fanfiction', others may find it offensive or disturbing. If the fanfiction contains excessive violence and torture without any redeeming narrative or moral exploration, it's likely not appropriate.
I'm not sure specifically as there could be many different interpretations of such a fanfiction. It might involve a character named Neal facing some form of extreme distress or harm within the context of a fictional story created by fans.
It's not extremely common, but it does exist. Some fans are interested in exploring how Naruto would react under extreme duress. However, many other types of fanfiction, like Naruto's training arcs or his romantic relationships, are more prevalent. But still, for those who like a more edgy and intense story, 'naruto gets tortured fanfiction' can be appealing.
Alec might also come to her rescue. As a skilled Shadowhunter, he has a strong sense of duty. Plus, he's part of Clary's group, and he wouldn't stand by and let a fellow Shadowhunter be attacked by a demon.
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.
Well, she might be rescued by her friends. In many fanfictions, her Shadowhunter comrades would come to her aid, using their unique skills to fend off the attackers.
