Why did Magnus break up with Alec when he was pregnant in fanfic?

One reason could be miscommunication. Maybe they didn't fully understand each other's needs and wants. For example, Alec might be too focused on his shadowhunter duties and not give enough time to Magnus, who would then feel neglected.

Some fanfics might show Alec being very stoic at first, hiding his pain. He's used to bottling up his emotions as a shadowhunter. But later, he might break down in private. For Magnus, he could be more openly heartbroken, showing his emotions through his magic, like making the room around him dark and stormy.

Well, one possible plot development could be that they initially avoid each other. Alec might throw himself into his work with the Shadowhunters, trying to forget Magnus. Magnus, on the other hand, could start traveling to different magical realms to distract himself. But as time passes, they might start to cross paths again, perhaps due to some common threat to the Shadow World. And slowly, they might start to remember the good times they had and question if the break - up was really the right decision.

Obviously, Alec and Magnus are the main characters. But new characters could also be introduced. For example, a new Shadowhunter trainee who looks up to Alec and tries to help him get over Magnus. Or a powerful warlock from another dimension who becomes Magnus' friend and tries to show him that there are other options besides Alec. There could also be a seer who predicts that Alec and Magnus are meant to be together and tries to nudge them in the right direction.

In fanfiction, if Alec and Magnus had a daughter getting pregnant, it could be a very emotional and complex storyline. It might involve themes of family support, dealing with unexpected situations, and the young character's growth. Maybe she'd face challenges like how to balance her own dreams and the new responsibility.

One common way could be through using his magic in a subtle way. For example, he might use magic to create situations where Alec has no choice but to follow his lead. Maybe he makes it seem like the only option for Alec to protect his friends or family is to do what Magnus wants.

One characteristic is the focus on the relationship between Alec and Magnus. It could be their romantic relationship, like in many fanfics where their love story is explored in great detail. Another is the exploration of their individual personalities. For instance, Alec's loyalty and Magnus's magic are often highlighted.

They might love fanfiction because it offers different perspectives on their relationship. Fanfictions can explore aspects that might not be fully covered in the original works.

Love is a very common theme. Their relationship, which is between a Shadowhunter and a warlock, is full of challenges and the fanfics often explore how they overcome these through love. Another theme is acceptance. Alec has to accept Magnus's different lifestyle as a warlock, and Magnus has to accept Alec's duties as a Shadowhunter.

He may also try to reason with Magnus or the kidnappers. Alec is a smart guy, so he might try to find a way to get out of the situation through dialogue. He could point out the negative impacts of their actions on everyone involved.
