One interesting fanfiction could be 'The Unlikely Bond'. In this, Voldemort's care for Snape might be a strategic move at first. He realizes Snape's value in spying on Dumbledore and the Order. As time goes on, it becomes a complex relationship where Voldemort starts to actually care in his own twisted way. It shows a different side of both characters and how power dynamics can shift in unexpected ways.
It might exist because the author was writing more for themselves than for an audience. Some people write fanfiction just to explore their own ideas and don't really focus on making it appealing to others.
It could imply that the Harry Potter fanfiction in question was not getting any attention. Maybe it was poorly written, or perhaps it was in a very niche area that few people were interested in.
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.
It could be that the author wanted to play with the idea of role reversal or to explore a different kind of caregiving scenario. Perhaps it adds a layer of vulnerability to Harry and showcases a different aspect of Hermione's character.
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.
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.
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.
