One interesting aspect is the exploration of Snape's complex character in more depth. Fanfiction often delves into his past, his unspoken emotions, and his relationships in ways that the original series might not have fully explored. For example, it could expand on his time as a Death Eater and his internal struggles.
Well, Severus Snape is obviously the central character. But often, other characters from the Harry Potter series are also involved. Harry Potter himself is frequently present as his relationship with Snape is a key part of the original story. Hermione Granger and Ron Weasley may also show up, as they are important in the wizarding world and their interactions with Snape can be explored in different ways in fanfiction.
Harry Potter could visit Snape in the hospital. Despite their past differences, Harry might feel a sense of obligation or curiosity. He could be there to finally have an honest conversation with Snape and perhaps gain a better understanding of his actions throughout the years.
Another way Snape could comfort Harry is by standing up for him in certain situations. Maybe when other teachers or students are being unfair to Harry, Snape steps in and defends him. This act of protection can be a great source of comfort for Harry, as it shows that someone is on his side even if they have had a rocky relationship in the past.
Snape might initially be shocked. He's not one to show much emotion openly, but internally he could be very disturbed. He might start investigating what happened to Hermione immediately, using his skills in potions and magic to try and find a cure or at least understand the cause.
Snape could initially be skeptical. Given their long - standing enmity, he might not believe that Harry's apology is sincere at first. He might respond with a cold glare or a sarcastic comment, like 'Potter, your apologies are as empty as your head.'
To evaluate Snape's characterization, look at how his loyalty is portrayed. In the original series, he was loyal to Dumbledore but also had a complex past with Voldemort. His relationship with students, especially those in Slytherin, should also be considered. If he's too soft or too harsh compared to the books, it might be a sign of poor characterization.
There could be other Death Eaters that Snape knew in his life. In the afterlife, they might be there to either confront him about his double - agent status or to seek redemption themselves. And sometimes, characters from Snape's childhood, like his parents or childhood friends, might appear to add more depth to his backstory and his experiences in the afterlife.
This could be a modern AU (Alternate Universe) fanfiction where the magical setting is replaced with a contemporary one and Snape takes on a non-magical job like being a bartender.
One of the great ones is 'The New Adventures in the Kane Chronicles'. It takes the characters on new and exciting quests that feel like they could be part of the original series. Another good one is 'Kane Chronicles: Alternate Endings' which explores different ways the story could have ended. And 'The Kane Chronicles: Extended Tales' gives more backstory to the characters.
