It might also affect his friendships. Some of his friends could be disappointed in his decision if they are really into potions. On the other hand, it could bring him closer to those who support his choice. This shift in relationships can create new sub - plots and twists in the fanfiction story.
His quitting potions could open up new storylines. He might have more time to explore other areas of magic or get involved in different adventures. For example, he could start an independent study of a unique form of magic that was not possible when he was occupied with potions. This can add more variety to the fanfiction plot.
It can create a power vacuum. If Snape held an important position in the fanfiction, like a teacher or a key figure in a magical organization, his quitting would leave that role empty, leading to chaos or new power struggles.
It can greatly affect the plot. For instance, if Harry is female, the way Voldemort views her could be different. He might underestimate her in some ways or be more intrigued by her. This could change the sequence of their confrontations. Also, if Hermione is male, his friendship with Ron and Harry could have new tensions. Maybe he'd be more competitive with Harry, which could lead to different sub - plots within the story.
It can completely change the direction of the plot. For instance, if Harry absorbs the Horcrux early on, he may have to face different challenges than in the original story. He might become a target for both sides, as the good side could be wary of his new, Horcrux - influenced state, and the bad side might see him as a threat to Voldemort's power.
It can create a lot of drama. For instance, it can lead to a rift between Harry and Ginny's friends who might be on different sides. Some friends might side with Ginny, thinking she has valid reasons for the rejection, while others might support Harry and try to get them back together.
It can greatly change the plot. If Harry has a different name, like Ethan, for example, Voldemort might not target him as easily. This could delay the start of the main conflict in the story. Or, it could cause the Order of Phoenix to be more cautious in approaching him as they may not be sure if he's the 'Chosen One' with this new identity.
If the sister has a romantic relationship with one of the characters, it can add a whole new dimension to the plot. Love triangles can form, causing jealousy and tension among the characters. This can also drive character development as they have to navigate their feelings while dealing with the greater threats in the wizarding world, like the ever - present danger of the Death Eaters.
It can add a new layer of intrigue. Readers will be curious about why he renamed himself and what he hopes to achieve. This can keep them engaged as they try to figure out the motives behind the name change.
His potion - making skills might make him more respected by his classmates. They could come to him for help with their potions homework or for advice on how to improve their own skills.
Some fans might be very disappointed as Ginny and Harry had a much - loved relationship in the original books. It could lead to a lot of debate within the community, with some fans strongly against such a plotline and others being more open to exploring different and darker aspects of relationships.
It can make the story more intense. A pissed - off Harry Potter is likely to take more drastic actions. For instance, he might be more aggressive in his fight against the dark forces, which can drive the plot forward quickly.
