Snape's view of Harry would be completely transformed. Normally, he's so focused on Harry's mistakes and similarities to his father. But if he catches Harry cutting, he'll see a side of Harry that is broken and in pain. He'll no longer be able to simply write Harry off as a brat. Instead, he'll have to face the fact that Harry is a real person with real problems. This could lead to Snape developing a newfound respect for Harry, as he realizes that Harry has been dealing with a lot more than he let on. And it could also make Snape more determined to help Harry, whether it's through magic or just being there for him in the fanfiction.
Snape's view of Harry would likely become more complex. He might see Harry as more vulnerable than he previously thought. His initial disdain might turn into a sort of begrudging concern. He would realize that Harry is dealing with deeper issues than just being the 'Boy Who Lived'.
In the fanfiction world, if Snape finds Harry cutting, he might be initially shocked and angry. He could see it as a sign of Harry's inner turmoil. Snape, despite his complex relationship with Harry, might feel a sense of responsibility. He might immediately take steps to stop Harry from further harming himself, perhaps using his magic to heal the cuts. And then he would likely question Harry about why he was doing such a thing, trying to get to the root of the problem.
Well, Snape has always had a complex relationship with Harry. When he finds Harry cutting himself in this fanfiction, he might be angry at first, thinking it's a sign of weakness. But then, as he realizes the depth of Harry's pain, he could soften. He might start to see Harry more as a troubled child rather than just James Potter's son. Snape could use his knowledge of potions to create something to heal the physical wounds and also try to offer some form of emotional support, albeit in his own gruff way.
In this kind of fanfiction scenario, Snape might initially be conflicted. On one hand, he has his long - standing dislike for James Potter, Harry's father. But on the other, his sense of duty as a Hogwarts professor could kick in. He might reluctantly start to heal Harry, all the while muttering under his breath about how much trouble Harry always seems to get into, just like his father. Then, as he heals Harry, he might start to see some of Lily, Harry's mother, in him and soften a bit.
Well, at first Harry might be very suspicious. But as Snape shows consistent care, Harry could start to see him in a new light. Maybe he realizes that Snape has more layers than he thought. He might begin to understand that Snape's past actions were more complex than just being mean to him.
Well, if everyone found out Harry was Snape's son, it would completely shatter the existing relationships. For one, Harry's relationship with the Dursleys might be even more strained as they already dislike him, and this new revelation could make them feel even more threatened. His relationship with Ron and Hermione would also be tested. They might be confused and even a bit betrayed at first. Hermione, being the logical one, would probably try to find out how this could be possible. Ron, on the other hand, might have a more emotional reaction. And as for Snape himself, his whole attitude towards Harry would have to change drastically. He couldn't keep up the pretense of hating Harry when it turns out he's his son. It would also change the way the wizarding world views Harry. Some might be more sympathetic, while others might be suspicious of Snape's motives all along.
It could be the pressure of being 'The Boy Who Lived'. Harry has so much expected of him all the time, and it might just be too much to bear.
Snape's view of Harry might become more sympathetic. He would see Harry as a victim rather than just an annoying student. This could lead to a softening of his attitude towards Harry in general.
In many Snape and Harry slash fanfictions, Harry often becomes more understanding of Snape's past and his motives. He starts to see beyond the grumpy exterior. Snape, on the other hand, may become more vulnerable and open. For example, in some stories, Harry's kindness breaks down Snape's walls.
In a scenario where Draco finds Harry cutting fanfiction, it could potentially change the dynamic between them. Fanfiction often involves a lot of creativity and personal investment from the writer or editor (in this case, Harry). Draco might not understand this at first. But if he takes a moment to think about it, he could realize that Harry has a passion for this fictional world in a different way. It could be a moment of growth for Draco, where he starts to see Harry not just as an enemy but as a person with diverse interests. Or, it could go the other way and just be another source of conflict between them, with Draco making fun of Harry's hobby and Harry getting defensive.
One reason could be a surprise attack by Voldemort or his Death Eaters. Maybe they found a way to bypass all the protection spells around Harry and launched a sudden, fatal assault.
