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.
Well, Snape uses his extensive knowledge of potions. He might show Harry how to handle different ingredients carefully, like how to cut the shrivelfigs just right. And he'll lecture on the importance of precision in measurements, which is crucial in potion - making. Snape also likely demonstrates the correct brewing sequence for various potions, making sure Harry understands the steps thoroughly.
In some fanfics, Snape may use a potion similar to the Felix Felicis, the luck potion. But instead of just bringing luck, this modified version could be used to change Harry's fate or the course of his actions. It could make Harry more inclined to make certain choices that Snape desires. Also, there could be a potion that can temporarily suppress Harry's magic, which Snape might use to keep Harry out of trouble or to protect him in a different way.
Well, in many fanfictions, Snape might do it through private lessons, sharing personal experiences, or guiding Harry in understanding emotions.
Snape could teach Harry about the importance of potions. Potions are a crucial part of magic in the wizarding world, and Snape is an expert in this area. He could pass on his in - depth knowledge of potion - making techniques and the properties of different ingredients.
In some fanfictions, Snape might use his advanced knowledge of potions to create a special concoction to heal Harry. He could draw on his skills in Herbology as well to find rare ingredients for the potion.
Snape is likely to be initially suspicious. He has long held a rather negative view of Harry, so when he discovers Harry is good at potions, he might think Harry has some ulterior motives or has received improper help. After all, in the regular Hogwarts setting, their relationship is quite tense.
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 'Snape kills Harry' fanfiction would shatter the relationships that were built in the original series. For example, the friendship between Harry, Ron, and Hermione would be left in tatters. Hermione and Ron would be devastated and likely seek revenge. Also, Dumbledore's plan, whatever it was that involved Harry, would be completely ruined. The whole balance of good and evil in the wizarding world would be thrown into chaos.
By the end of the series, after Snape's death, Harry fully realizes the sacrifices Snape has made for him. Snape's attitude towards Harry was always influenced by his love for Harry's mother, and in the end, Harry understands and respects Snape in a way he couldn't before.
Well, it completely flips the dynamic. In the original series, Snape was a complex character with a lot of hidden motives that were ultimately revealed to be on the side of good. If Harry kills Snape in the fanfic, it makes Harry seem more impulsive and less of the heroic figure we know. It also undermines the redemption arc that Snape had in the original story.
The development could also be due to the way the author writes Snape's backstory in the fanfic. If the author delves deeper into Snape's past, his difficult childhood, and his love for Harry's mother, Harry might start to understand Snape better. This understanding leads to admiration as Harry realizes that Snape is not just the strict and seemingly cruel professor he thought he was.
