It could be that he fails at a very important potion-making task. Harry might have put a great deal of effort into it, and when it goes wrong, the disappointment gets to him and he cries. For example, if it was a potion crucial for saving a friend or getting good grades, and he messes it up.
Perhaps he has some personal issues that come to the surface during potions class. Maybe he's thinking about his parents' death or the danger his friends are in, and the stress of it all just overwhelms him while he's in that class.
Maybe he's being bullied by Snape. Snape has always been tough on Harry in potions class. His harsh words and unfair treatment could easily make Harry feel frustrated and cry.
The grading system in this fanfiction's potions class could be different. Instead of the usual strict letter grades, it could be more focused on improvement and creativity. So, a student who comes up with an innovative way to make a potion, even if it doesn't turn out perfectly, could still get a high mark. Also, group projects could be a major part of the class, promoting teamwork among the students which was not always emphasized in the original potions class.
One interesting scenario could be a new student who has an unexpected natural talent for potions, much to Snape's surprise. This student might be able to create complex potions with ease, while others struggle.
Maybe Harry has had some secret interactions with Snape that the readers haven't known about yet. These interactions could have made Harry feel a father - like connection to Snape, and in the heat of the moment in potions class, he just blurts it out.
For Harry, a different potions class might make him more interested in the subject. Since he often had a tough time with Snape, a new teacher or teaching style could make him see potions in a new light. He might start to enjoy the process of making potions and even excel at it. Hermione, on the other hand, would probably adapt quickly to any changes. She might use the new opportunities in the class, like new potions to study, to expand her knowledge even further.
Hermione Granger is often a central character. Since she is known for her academic excellence, she would be shown as the star pupil in potions class, acing every potion and helping others when they are in trouble.
Hermione would most likely be the first to help. She's always been there for Harry and is very knowledgeable in potions. She might quickly assess the situation and try to find a counter - potion or spell to revive him.
In some fanfictions, Harry might be good at potions because the author wants to give him a new skill set. It could be that they want to show his growth and development in a different area than in the original books. Maybe he has a secret mentor or he discovers a hidden talent within himself through some unique experiences in the fanfiction world.
It could be that Harry reads Harry Potter fanfiction to feel more connected to his fans. By reading what they write, he gets a sense of how they view him and his friends. He might also find comfort in the fact that his story has inspired so many people to create their own tales within the same universe. Fanfiction can be a form of flattery, and Harry might enjoy seeing how much his story has captured the imaginations of others.
Snape teaches Harry about potions in a rather strict and demanding way. He often criticizes Harry's mistakes harshly but also imparts important knowledge about potion - making techniques, ingredient properties, and the correct procedures to follow in the classroom.
Sure. There could be many reasons for Harry to like potions fanfiction. Maybe he wants to see different interpretations of the potions he has learned in Hogwarts. Fanfiction often provides alternative scenarios and character developments, which can be really appealing to someone like Harry who has a personal connection to potions.
