Perhaps in this context, 'in charge' implies that Hermione has some sort of editorial role. She could be the one who decides which Dolohov fanfictions are promoted or featured. It might also suggest that she is the main contributor to this particular area of fanfiction writing.
It might be a very specific scenario within a fanfiction universe. For example, in a story where the world of fanfiction has its own hierarchies and roles. Hermione, being a very intelligent and organized character, is given the task of overseeing the Dolohov fanfiction. This could involve tasks like keeping track of different plotlines, ensuring consistency among the stories, and perhaps even guiding other writers who contribute to this genre of fanfiction.
She could use her intelligence and love for books. Hermione is known for her studious nature. So she might apply her knowledge of storytelling and literary techniques to manage the Dolohov fanfiction.
Hermione would likely react with her usual intelligence and quick - thinking. She might start by trying to analyze Dolohov's motives and weaknesses. She could also try to find a way to communicate with the outside world, perhaps using magic in a very discreet way.
She is likely to be defiant. Hermione has always been a strong - willed character. So she would probably not go down without a fight. She might immediately start looking for ways to escape or undermine Dolohov's plans.
He might start off as a rather dark and untrustworthy character. But as he helps Hermione, he could gradually become more empathetic. Maybe he sees the good in Hermione's cause and starts to question his own past actions.
One possible plotline could be Hermione getting to know Dolohov in an alternate universe where he has a different side to him. Maybe she discovers some hidden good in him and tries to redeem him.
One popular place to find such fanfiction could be Archive of Our Own (AO3). There are likely many stories there that explore this concept. Just search for 'Dolohov wants Hermione' on the site and you'll get a list of relevant fics.
It could mean that the fanfiction in question doesn't accurately represent the true essence of the character Hermione. Maybe it has her in a situation or with characteristics that are completely out of line with how she is in the original work.
One common theme is the battle of wits. Hermione is known for her intelligence, and when facing Dolohov, it becomes a test of who can outsmart the other. Another theme is the power of magic. Writers often explore different magical abilities that Hermione can use against Dolohov. Also, the theme of good vs. evil is present, as Hermione represents the good side and Dolohov is on the dark side.
One common theme is mystery. Since Dolohov is following Hermione, there's always the question of why he's doing it. Another theme is power struggle. Hermione is a powerful witch in her own right, and when Dolohov follows her, it sets up a situation where their respective powers and wits are pitted against each other.
Another theme is the power of redemption. Sometimes in these fanfictions, Dolohov's attraction to Hermione leads him to question his dark ways and consider redemption. Hermione's presence in his life becomes a catalyst for change.
