Well, it might result in a confrontation. Snape has his own secrets and motives, and Hermione is not one to back down easily. If she's in the dungeon without permission, Snape could be quite harsh with her. However, some fanfictions take this in a different direction. Maybe Hermione discovers something about Snape's past while in the dungeon, and this knowledge makes Snape more vulnerable in front of her. It could be a turning point where their relationship goes from antagonistic to something more complex and nuanced.
A common theme could be redemption. Snape, who has a complex and often - dark past, might find in Hermione a chance to redeem himself in some way. Maybe he saves her from a danger in the dungeon, which starts his journey towards a more positive path. Another theme is the exploration of hidden knowledge. The dungeon is full of secrets, and both Snape and Hermione are curious minds. They could uncover something that changes their understanding of Hogwarts or the wizarding world.
One possibility is that Snape initially refuses to help Hermione. He has his own grudges and is often portrayed as a cold character. But as the story progresses, he might see something in Hermione's situation that relates to his own past or values, and reluctantly start to offer some guidance.
In a fanfiction scenario, perhaps the Death Eater has a change of heart when he sees Hermione hiding. He could be secretly against Voldemort's ways and decides to help her. They might form an unlikely alliance, with the Death Eater protecting Hermione from other dark wizards. Or, the Death Eater could be under a spell or curse that makes him act differently when he encounters Hermione, leading to a very strange and unexpected encounter.
She might struggle with her new identity at first. After all, she has always been seen as a Muggle - born. This new discovery could make her question her place in the wizarding world. She may start to explore her pureblood heritage, looking into her family's past and any special magical abilities or traditions that come with it.
Snape might suspect that there is some dark magic at play. Given his knowledge and expertise in the Dark Arts, he would immediately look into any signs of foul play. He could also be conflicted because on one hand, Harry is a student he has had many issues with, but on the other hand, he is also an important figure in the fight against Voldemort. So he would have to decide whether to report Harry's disappearance or try to handle it privately.
One possibility is that Snape would be extremely strict with them at first. Given his past relationship with Harry especially, he might struggle to show affection openly. But over time, he could come to understand the trio better. Harry would likely be the most resistant to Snape's parenting at the start, but as Snape showed his genuine care, Harry might warm up. Hermione would probably be eager to learn from Snape, seeing his vast knowledge. Ron, on the other hand, might find Snape's gloomy demeanor a bit off - putting, but with Hermione and Harry's influence, he'd also adapt.
One possibility is that Hermione would be extremely shocked. She might initially think it's some sort of joke or a test. Given their previous relationship in the original story, where Snape was often strict and not exactly friendly towards her, this sudden change would be quite a surprise. She might hesitate and not give an immediate answer, needing time to process this unexpected turn of events.
She might start to search for her biological parents. This could lead her on an adventure full of mystery and self - discovery. She could use her intelligence and magical skills to track down any clues about her origins.
In a fanfiction scenario where Naruto finds a lightsaber, he could potentially incorporate it into his fighting style. He's always been creative in combat. He might use his ninja skills like speed and agility along with the lightsaber's unique capabilities. For example, he could use his shadow clone jutsu and have his clones all wield the lightsaber in different ways to confuse his enemies.
He might meet someone who is also after the scythe. This could lead to a conflict or an alliance. If it's an enemy, Naruto will surely fight to keep the scythe. But if it's someone who can help him understand the scythe better, they could team up and go on adventures together.
