Perhaps in the fanfiction, Bellatrix stabs Hermione as a way to get to Harry Potter. She might think that by harming Hermione, she can draw Harry out and into a trap. Hermione is one of Harry's closest friends, so this would be a strategic move on Bellatrix's part.
In the original Harry Potter story, Bellatrix doesn't actually stab Hermione. So in the fanfiction, this is a major deviation. It changes the relationship dynamics between the characters. For example, in the original, Hermione and Bellatrix have their tense encounters but not to this extreme level of physical harm.
In Hermione and Bellatrix fanfiction, the power dynamic is often an interesting point. Bellatrix has a great deal of power as a Death Eater, but Hermione has her own kind of power in her knowledge and magic skills. Some fanfictions may show a battle of wills between them, where Hermione refuses to be intimidated by Bellatrix's threats. This can lead to some really intense and exciting storylines, like when Hermione stands up to Bellatrix in a duel - like situation in a magically - created arena within the fanfic's plot.
One possible aspect of Hermione and Bellatrix fanfiction could be the exploration of their opposing natures. Hermione is a studious, rule - following Gryffindor, while Bellatrix is a wild and chaotic Death Eater. Fanfiction might play with the idea of how they interact in different scenarios. For example, in a scenario where Hermione is captured by Bellatrix, their exchanges could be filled with tension and power plays. Hermione's intelligence could be pitted against Bellatrix's brute force and loyalty to Voldemort.
Yes, there are likely fanfictions out there with such a plot. The 'Harry Potter' fandom is vast and diverse, and some fanfiction authors explore dark and alternate storylines. However, these often deviate from the original positive and heroic themes of the series.
Living with Bellatrix would be a terrifying experience for Hermione. However, she would rely on her wits. She would probably keep her Gryffindor courage in check and act more like a Slytherin, being cunning and sly. She might start to understand Bellatrix's insecurities and use them to her benefit. For instance, if Bellatrix is insecure about her standing among the Death Eaters, Hermione could offer advice that seems helpful but actually undermines Bellatrix's loyalty to Voldemort. And she would constantly be on the lookout for any signs of kindness or humanity in Bellatrix, hoping to use it as a way to change the situation.
One reason could be pure hatred. Bellatrix despises Muggle - borns, and Hermione being a very intelligent and powerful Muggle - born would be a prime target for her wrath. Another could be jealousy. Hermione's skills and knowledge might make Bellatrix feel inferior, leading her to lash out.
At first, Hermione would probably be in shock and defiance. But she'd quickly start to strategize. She'd use her vast knowledge of magic to protect herself from Bellatrix's potential outbursts.
One possible plot could be that Bellatrix captures Hermione and tries to torture her for information about Harry. But Hermione, using her wits and some new-found powerful magic she has been secretly studying, manages to turn the tables and kill Bellatrix in self - defense.
