Dumbledore can also be a significant character. He might be the one who arranges for Snape to teach Harry, having some grand plan in mind. He could be observing from the sidelines, guiding Snape's actions and Harry's progress subtly.
Sometimes Ron is involved too. He might not understand why Harry is spending so much time with Snape and get a bit suspicious. This could lead to some tension between him and Harry, until Harry finally explains the importance of what he's learning from Snape.
Dumbledore could be involved. He often has his fingers in many pies at Hogwarts, so he might be the one who arranges for Snape to deliver the letter to Harry for some greater good or part of his grand plan. Another possible character could be Hermione. She might notice something strange about Snape delivering the letter and start to investigate, suspecting that there's more to it than meets the eye.
Ron could also be there. He might be in charge of something like the Gryffindor Quidditch team or be a part - time teacher teaching the younger students about the magical history of the Weasley family's inventions. His humor and loyalty would be a great addition to the story.
Luna Lovegood might be in the fanfiction. She has a unique perspective on magic, and she could offer some interesting insights during the examination. Neville Longbottom could also be present. He's been through a lot in the wizarding world, and his presence could add another layer to the story. Additionally, some fanfictions might include characters from Snape's past, like Lily Potter. Her presence, either in flashbacks or in some magical form, could greatly affect the dynamic between Snape and Harry during the examination.
Harry Potter is often a common character. His relationship with Snape was complex in the original series, and in fanfiction where Snape is a father, it can add another layer of complexity. Harry might be involved in some way, either as an ally or an antagonist to Snape's new - found family situation.
Harry Potter is a very likely character. Given his often - tense relationship with Snape, detention with Snape could be a great opportunity to explore their dynamic further. Harry might learn more about Snape's motives during these detentions, or they could have some unexpected conversations that change Harry's perception of Snape.
Hermione is often involved. She would be curious about Harry's new ability and might try to research more about it in the library. She could also help Harry figure out how to use this ability to their advantage in different situations.
Ron could also be a main character. He might be a bit scared or jealous of Harry's new - found ability. But in the end, he stands by Harry. Maybe there's a scene where Ron has to overcome his fear of snakes when they are in a dangerous situation that requires Harry to talk to a snake for help.
Hermione is often involved. Since she's Harry's best friend, she might be the one trying to prevent his death in some fanfictions. Or she could be the one who has to carry on his legacy after he dies.
Dumbledore is another character who is often included. Given his role in Snape's life and their shared secrets, in the afterlife they might continue their discussions or Dumbledore could be the one to help Snape come to terms with his past. Voldemort could also be mentioned in some fanfictions, especially if the fanfiction explores the long - term effects of Snape's actions against Voldemort in the context of the afterlife.
Hermione is often involved. She might help Harry understand the complex magic associated with the Elder Wand. For example, she could research in the library to find out any hidden lore about the wand.
