One alternative could be fanfiction that focuses on Snape mentoring Harry. For example, Snape could be teaching Harry advanced potions techniques or helping him understand the history of dark magic in a way that Dumbledore couldn't. This would show a more positive and educational relationship between them.
Another alternative is fanfiction that has them as allies in a fight against a greater evil. They could put aside their differences and work together to defeat a new dark wizard or a powerful dark magic threat. This would highlight their potential to cooperate and respect each other's skills and knowledge.
Most official platforms would not allow such inappropriate fanfiction. Fanfiction should be about creativity within the boundaries of respect for the source material and its characters. Instead of seeking such a fanfiction, you could search for ones that depict their relationship in a more platonic or mentor - mentee style, which are much more common and in line with the spirit of the 'Harry Potter' universe.
You could look for fanfictions that expand on the magical aspects of the 'Harry Potter' world. Maybe ones that introduce new spells or magical creatures. Another alternative is fanfictions that deal with the post - war rebuilding of the wizarding world, showing how the characters are coping and rebuilding their lives.
Some fanfictions might center around Snape's hidden admiration for Harry's courage in a non - inappropriate way. It could show how Snape, despite his rough exterior, respects Harry's tenacity in the face of danger.
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.
In some fanfictions, Snape might use his advanced knowledge of potions to brew a special healing elixir for Harry. He could also use his magic skills, like a complex spell specifically designed to mend Harry's wounds, whether they are physical or emotional.
Snape is always complex. In this situation, he would be conflicted. On one hand, he has his long - standing dislike for Harry (or rather, his connection to James). On the other hand, as a teacher, he has a duty to take care of a student in distress. Drunk Harry would be a bit clumsy and giggly perhaps. His judgment would be clouded, and he might see Snape in a different light, not as the enemy but as someone who could help him, which could start to shift their relationship dynamic in the fanfiction.
Another reason might be that Harry is suspected of sneaking around in areas where he's not supposed to be. Snape, as a vigilant teacher, may punish Harry to maintain discipline in the school. He may think Harry is up to something related to the ongoing dangerous situations in the wizarding world and wants to keep him in line.
Sure, the Harry Potter fandom is huge and full of creativity. Writers might come up with a story where Harry is Snape's master for various reasons. It could be due to a prophecy or a magical bond that no one expected. In this kind of fanfiction, we might see Snape having to follow Harry's orders, which would be a complete reversal of their normal relationship in the original series. This could lead to some very intense and dramatic storylines.
One possibility could be that in this fanfiction, Snape takes Harry for some sort of training or protection. Maybe Snape realizes that Harry is in greater danger than Dumbledore anticipates and decides to take matters into his own hands. He might take Harry to a secret location to teach him advanced magic or to keep him away from the prying eyes of Voldemort's followers.
In fanfiction, Snape teaching Harry Occlumency is often a very intense and complex relationship. Snape's own mixed feelings towards Harry add layers of drama. His strict teaching methods sometimes seem cruel but are also necessary to force Harry to master Occlumency. Harry, on the other hand, is often resistant at first, not fully understanding the importance and also being put off by Snape's attitude.
