Jealousy can also be a common element. In these fanfics, there might be instances where Alec is jealous of Magnus's past relationships or his popularity in the Downworld. Magnus, on the other hand, could be jealous of Alec's closeness to his Shadowhunter friends or family. Another aspect is fear of abandonment. Given their different natures and the challenges they face in their relationship, both characters may fear that the other will leave at some point.
In many Alec and Magnus insecure fanfics, communication breakdown is a key element. Their insecurities often lead to misunderstandings and a lack of open communication. For example, Alec may be too proud or afraid to admit his insecurities to Magnus, and Magnus may try to hide his own behind his confident facade. This can create a cycle of miscommunication and further fuel their insecurities, making the relationship seem more tenuous and full of drama.
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.
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.
