She would likely be very self - reliant. Instead of panicking, she would take inventory of what she has with her - her wand, her books (if she has any). Then she'd start making her way, perhaps following the tracks her friends left if possible, all the while muttering to herself about how irresponsible they were.
She might be initially shocked. But being Hermione, she would quickly gather her wits and start planning. She could use her vast knowledge of magic to find her way or to signal her friends.
Hermione could feel hurt and angry at first. She might sit down and think about what led to this. Then, she would probably start exploring on her own, using her intelligence to solve any problems she encounters along the way. For example, if she comes across a locked door, she'd use a spell to open it rather than waiting for help.
She might withdraw. Hermione could become quiet and start spending more time alone, like going to the library even more often than usual. This is her way of protecting herself from further hurt.
Hermione could also get angry. She's a strong - willed character. So, instead of just accepting the situation quietly, she might confront her friends and demand to know why they are ignoring her. This could lead to a big argument or a revelation about what's really going on.
She might initially be in shock. Hermione is used to relying on her friends, so the betrayal would be a huge blow. She could then become angry and start to isolate herself. In some fanfictions, she might try to figure out why they did it on her own, using her intelligence to uncover the truth.
She might be initially shocked. After all, she would have trusted her friends a great deal. Then she could become very sad and withdrawn. She might throw herself into her studies even more as a way to cope, trying to distract herself from the pain of losing her friends.
After the initial reactions, Hermione may choose to isolate herself for a while to figure things out. She would use this time to study and research, trying to find a solution to the problem with her friends. She might also look for new allies or resources within the fanfiction world to help her deal with the situation.
She might be initially shocked and hurt. Hermione is a character who values her friendships deeply, so their sudden departure would be a big blow. She could spend some time in denial, not believing that they would actually leave her.
One possible reason could be a misunderstanding. Maybe her friends thought she was following but she got distracted by something, like a new spell she saw in an old book. So they unknowingly left her behind.
Harry and Ron would probably be very worried. They'd rush to her side immediately. Harry might use his skills to try and find a way to heal her quickly, while Ron would be freaking out a bit but also trying to be helpful.
Harry would probably be very shocked at first. He has had a long - standing rivalry with Draco, but seeing Hermione happy might make him gradually accept it. Ron would be more vocal in his disbelief and might take some time to warm up to the idea. Ginny, on the other hand, would be more open - minded and might be the first among Hermione's friends to support her. The Weasley family as a whole would be a bit divided, with some being more accepting and others more skeptical.
Another reaction could be self - reflection. She might start to question her study methods and her priorities. Maybe she realizes that she had been too focused on grades and not enough on truly understanding the magic, and this failure could be a turning point for her to change her approach to learning.
