One possible plotline could be Bellatrix's unwavering loyalty to Voldemort being tested. Maybe she discovers something about Voldemort's past that makes her question her blind devotion. For example, she could find out about some of his more cowardly actions that he has kept hidden from his Death Eaters. Another could be a scenario where Bellatrix tries to prove herself even more to Voldemort by taking on a dangerous mission that he initially doubts she can handle. This could lead to a deeper understanding between them, or it could backfire and cause a rift.
Yes, there are some out there. You can check fanfiction websites like Archive of Our Own. There are stories that explore their complex relationship in different ways, some might focus on Bellatrix's extreme loyalty to Voldemort being misinterpreted as love, while others might create more of a romantic undertone between them based on their shared dark ideology.
One common theme is loyalty. Bellatrix's unwavering loyalty to Voldemort is often a starting point which gets developed into a love - like relationship. Another is the idea of power. Their shared thirst for power can be portrayed as a bond that ties them together in a romantic way. Also, the darkness within them is a theme, as they both are immersed in the dark arts and that common ground can be seen as a basis for their relationship in fanfiction.
Many fanfics explore the theme of redemption for Bellatrix. They imagine scenarios where she could have turned away from the dark side. Her complex character, with her madness and loyalty, also makes her a great subject for psychological exploration in fanfics.
In a fanfic, their relationship could be more intimate on an emotional level. In the books, Voldemort mainly uses Bellatrix for her loyalty and her skills as a Death Eater. But in a fanfic, there could be moments where he actually confides in her about his fears or his long - term plans. Bellatrix, in turn, could be more of an advisor rather than just a follower.
It could be Voldemort himself. Given her extreme loyalty to him, it's not a far - fetched idea that there could be some sort of connection between them that led to her pregnancy.
Another theme is redemption. Many fanfics explore the idea of the daughter trying to atone for her mother's sins or break free from the cycle of evil that her mother was a part of. For example, she might try to use her magic for good instead of following in Bellatrix's footsteps.
The plot could involve the son trying to redeem his mother's name. He might go on a journey to find out more about her past, hoping to understand why she became so evil. Along the way, he meets various characters who knew his mother and has to deal with their mixed reactions towards him.
In many fanfictions, Bellatrix is often depicted as extremely loyal to Voldemort. She is seen as his most devoted follower, willing to do anything he asks without question.
Voldemort is often paired with Bellatrix in fanfiction. Their relationship in the original series was one of master and servant, but in fanfiction, it can be explored in more complex and romantic ways. Another character often paired with her is Narcissa. Their sisterly bond can be a central focus, or it can be twisted into something more sinister or complex in fan - created stories. Also, sometimes Sirius Black is paired with her in alternate universe stories, given their family connection and the contrast in their loyalties.
