It could make her more confident. Knowing that Snape, a powerful and complex wizard, is communicating with her privately gives her a sense of importance. This might lead her to be more assertive in her actions and decisions.
One possible reason could be that Snape has some hidden knowledge or magic that allows him to communicate in such a way. Maybe he's trying to protect Hermione secretly and this mind - talk is a discreet way to give her advice without others noticing.
Fanfiction often contains a wide variety of themes, but this particular theme involves inappropriate and unethical behavior. In the official 'Harry Potter' universe, Severus Snape is a teacher and Hermione is a student, so such 'dirty talk' scenarios go against the moral and ethical framework of the story. Most official platforms would not support or promote such fanfiction.
Perhaps Hermione back talks Snape when he makes a snide comment about Gryffindors. She could fire back with a well - reasoned argument about how Gryffindors have shown just as much, if not more, skill and bravery as Slytherins. This would not only put Snape in his place but also display Hermione's loyalty to her house.
It's unacceptable because it violates the power dynamic in the 'Harry Potter' world. Snape is a teacher and Hermione is a student. This kind of inappropriate interaction goes against the basic moral code of the series.
A major theme is the power dynamics. Snape has more knowledge and experience in magic, but Hermione is not one to be easily overshadowed. Through the mind link, they have to find a balance. Also, the theme of redemption often comes up. Snape has a complex past, and the mind link can be seen as a way for him to find some form of redemption, especially in Hermione's eyes. There's also the theme of unexpected connection. They are two characters who wouldn't normally be so closely connected, but the mind link changes that.
One possible interesting plot point could be Hermione using her vast knowledge to counter Snape's sarcastic remarks. For example, she might correct him on a potion - making detail he got wrong in front of the class. This would create a tense and engaging dynamic between them as Snape is not used to being challenged in such a way.
Snape, on the other hand, would be his usual brooding self, but perhaps more on edge because of Hermione's newfound boldness. He is still the strict and somewhat mysterious professor, but now he has to deal with a student who doesn't cower at his glares or biting remarks. His pride might be a bit bruised as Hermione challenges his authority.
She might give him cold stares in class. Hermione is not one to shy away from showing her emotions through her expressions. So, every time Snape is in her line of sight, she could fix him with a withering glare that clearly shows her displeasure.
Well, at first, they'd probably be very uncomfortable. Snape is used to keeping his thoughts private, and Hermione is a bit shocked by the sudden connection. But as time goes on, they'd become more understanding of each other. Snape would see Hermione's intelligence not as a threat but as an asset, and Hermione would see past Snape's grouchy exterior to the complex person he is.
