Obviously, Harry himself would be involved. And of course, there would likely be healers at St. Mungo's Hospital for Magical Maladies and Injuries. Hermione might also be there to support Harry, using her vast knowledge to help understand any complex medical conditions or procedures.
In this fanfic, perhaps Harry discovers a hidden health issue. For example, he might find out he has a rare magical malady that only a few wizards have ever had. This could lead to a whole new adventure as he searches for a cure.
In the 'snape is sent to check on harry family' fanfiction, Snape's relationship with the Harry family could be full of twists. At first, he might be there just to do his job. However, as he gets closer to them, he could find himself protecting them in his own way. He might even become a sort of mentor figure to Harry, teaching him things that Dumbledore or others haven't, because he has a unique perspective from being sent to check on them.
In some fanfictions, Snape might use his advanced knowledge of potions to create a special concoction to heal Harry. He could draw on his skills in Herbology as well to find rare ingredients for the potion.
One more to consider is 'Snape: Beyond the Surface'. In this story, the author explores Snape's relationships with other characters like Dumbledore and McGonagall. It shows how his interactions with them were not always as straightforward as they seemed in the original books and adds more depth to his character.
One great Snape fanfiction is 'The Prince's Tale Redux'. It delves deeper into Snape's relationship with Lily. It shows his internal struggles and how his love for her influenced his actions throughout the series. It gives a more in - depth look at his character than what was shown in the original books.
In some fanfictions, Snape is indeed portrayed as Harry Potter's father. Fanfiction allows for creative reinterpretations of the original story, and this is one such interesting deviation from the canon where Snape's complex relationship with Harry takes on a whole new dimension.
One plot twist could be that Snape discovers a hidden secret about Harry's family that changes his whole perception of them. For example, he might find out that there was a prophecy related to Harry that was different from what everyone thought.
In this kind of fanfiction scenario, Snape might initially be conflicted. On one hand, he has his long - standing dislike for James Potter, Harry's father. But on the other, his sense of duty as a Hogwarts professor could kick in. He might reluctantly start to heal Harry, all the while muttering under his breath about how much trouble Harry always seems to get into, just like his father. Then, as he heals Harry, he might start to see some of Lily, Harry's mother, in him and soften a bit.
One possible motive could be a misunderstanding. Maybe Snape is framed for something really bad, like a dark magic plot against Hogwarts. Harry, in his haste to protect the school and his friends, believes Snape is guilty and takes drastic action. Another reason could be if Snape accidentally endangers someone Harry loves dearly, like Ginny or Ron, and Harry's emotions get the better of him in the heat of the moment.
