Another possible reason is that the writer is exploring different character arcs. Snape has a very complex and well - known character arc in the original series. In fanfiction, the writer may feel that they've exhausted all the interesting possibilities for his character and quitting is a way to end his part in a somewhat conclusive way. It could also be related to the relationships Snape has in the fanfiction. If those relationships reach a point of no return or resolution, his quitting could be a natural consequence.
One reason could be that the writer wants to create a new plot twist. Maybe Snape's character has fulfilled its purpose in the fanfiction's storyline and his quitting can lead to new developments for other characters.
There could be an excess of alternate universes. Fanfictions often create all kinds of wild AUs for Snape. Maybe he's tired of being in so many different scenarios that don't really stay true to his essence. For example, some AUs make him a modern - day rock star or something completely out of character.
Burnout. Writing fanfiction, especially about a complex character like Severus Snape, can be mentally taxing. If a writer has been churning out stories for a long time, they might simply be tired. They may have written so many different versions of Snape's story that they can't think of any more variations.
One reason could be guilt. In the original story, Snape had some complex feelings towards Harry's father. By protecting Harry in fanfiction, he might be trying to make up for the past. It's like he's trying to right the wrongs that were done to Harry间接 because of his relationship with James Potter.
In fanfiction, one reason could be his desire for a fresh start away from the memories at Hogwarts. Maybe he feels he has done all he can there and wants to explore new magical knowledge elsewhere.
It can create a power vacuum. If Snape held an important position in the fanfiction, like a teacher or a key figure in a magical organization, his quitting would leave that role empty, leading to chaos or new power struggles.
Isolation. Snape is a lonely character. He doesn't have many friends, and he is constantly in a difficult position between the Death Eaters and the Order of the Phoenix. His feeling of being alone and not being fully understood by anyone can lead to crying in fanfiction.
One possible reason could be that fanfiction often takes creative liberties that may distort the complex character of Snape that J.K. Rowling created. Snape has a very intricate backstory and personality in the original series, and fanfiction might simplify or misinterpret it.
One possible reason could be the extreme stress he endures. In many fanfictions, Snape has to constantly balance his double - agent role during the war. The pressure of keeping his true loyalties hidden from Voldemort and his Death Eaters while also trying to protect the students at Hogwarts can be overwhelming, leading to a collapse.
A creative reason could be a magical prank gone too far. The Marauders or some other mischievous students play a prank on Snape using a new, untested spell. The spell backfires and Snape ends up in a state where he needs to be diapered. This would lead to a story of revenge, forgiveness, or just chaos at Hogwarts.
A common reason is that he's under extreme stress. In the world of Hogwarts, Snape has to constantly balance his double - agent life. The stress of hiding his true allegiances from Voldemort and the Order of the Phoenix can take a toll on his body. So, it's not unthinkable that this stress could make him physically ill, leading to vomiting. Another reason could be his love for Lily. In some fanfictions, memories of her, especially painful ones like her death, can be so overwhelming that it causes a physical reaction like throwing up.
