Perhaps there are situations where Hermione seems overly possessive. Like when it comes to group projects or activities, if she doesn't like it when others take Harry's attention away from her for too long. Harry could see this as jealousy. Also, it might be related to her competitive nature. If she sees someone else getting praise or attention from Harry that she thinks she deserves more, it could lead Harry to think she's jealous.
It could be that Hermione feels overshadowed in general. Harry is already famous in the wizarding world, and now if he's also doing well academically, she might worry that she's becoming less important. Also, she might be afraid that Harry is getting all the attention from the teachers, especially those she really respects, like Professor McGonagall.
Perhaps Harry was trying to hide from some danger. He knew that Hermione's place was one of the safest. So he transformed into his Animagus form and made his way to Hermione, and she took him in as a pet. In his animal form, he could stay close to her and keep an eye on things while remaining undetected by the source of the danger.
Maybe she's yelling at Ron. Their relationship in fanfictions can be quite complex. If Ron says something insensitive or does something stupid, like forgetting an important task that could put their mission in jeopardy, Hermione would surely yell at him.
Maybe some people who are not familiar with the real 'Harry Potter' story misinterpret it. They might have heard some false rumors or misread some fan - made parodies and thought it was related to archdemons.
Maybe Fleur was just being playful. In some fanfictions, characters might have these sorts of physical interactions as a form of friendly teasing or a quick, impulsive action without any real harm intended.
One possible misunderstanding could be a lack of knowledge about the two different fictional worlds. Someone who is not well - versed in either 'Harry Potter' or 'One Piece' might randomly combine elements from both. Another reason could be a misinterpretation of the concept of fanfiction. They might think that just because they can imagine some crossover in their head, it means one can be considered fanfiction of the other, without understanding the proper boundaries of different fictional IPs.
This statement is completely untrue. 'Harry Potter' is a unique and original fantasy series created by J.K. Rowling. It has its own independent world - building, including Hogwarts School of Witchcraft and Wizardry, the Ministry of Magic, and a host of unique characters like Harry, Hermione, and Ron. There is no relation to 'Lucifer' fanfiction at all.
Maybe John was frustrated at Sherlock's eccentric behavior. Sherlock often acts in ways that are outside of normal social norms, like his extreme focus on cases and disregard for basic social niceties. This could have led John to lash out and call him a 'freak' in a moment of exasperation.
Perhaps Hermione has her own plans regarding Runes. For example, she might have wanted to study Runes with Harry in a particular way or at a certain time. When Harry starts taking Runes on his own or in a different manner, it disrupts her plans, leading to her anger. Also, she could be worried that Harry's approach to Runes might get him into trouble or affect his overall academic progress in a negative way.
A favorite scene in such fanfiction could be when Hermione finally confronts Harry about his actions that made her jealous. There's a lot of tension in the air as she tries to hold back her emotions but fails. Harry is left stunned and realizes how much he means to Hermione.
