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.
One possible reason could be excessive stress. Hermione is known for being a perfectionist, and the pressure to perform well on the OWLS might have gotten to her, causing her to make silly mistakes during the exams.
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 Then she could become very sad and withdrawn.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.
A possible way to develop their relationship is through a magical owl - related research project. Hermione, being the studious one, is eager to participate, and Snape is in charge. As they work on the project, they exchange ideas and arguments. Over time, Hermione starts to respect Snape's vast knowledge, and Snape begins to appreciate Hermione's fresh perspectives. This could transform their relationship from a hostile one to a more amicable one.
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 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.
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.
Another storyline might involve an owl that has a special connection to Snape. Hermione notices the strange behavior of the owl towards Snape and starts to investigate. As she delves deeper, she uncovers some hidden aspects of Snape's life that change her perspective of him. This could lead to a friendship or a begrudging respect between them.
