In the original book, Harry Potter and the Prisoner of Azkaban, Sirius was Harry's godfather. He had been secretly protecting Harry and eventually saved him. Although the movie did not explicitly mention that Hagrid met Sirius on the road and gave the car to Hagrid, Sirius's role in the story was still Harry's protector and ultimately saved Harry. Harry Potter and the Prisoner of Azkaban wasn't enough. Everyone, please click to read the novel!
In fanfiction, it could be that the NCIS has some sort of magical knowledge or artifacts. Maybe they've been dealing with cases that are on the fringes of the wizarding world without realizing it. When they discover that Harry Potter is in danger, they use this knowledge or these artifacts to save him. For instance, they could have an ancient amulet that can counter dark magic spells aimed at Harry.
I'm not entirely sure specifically as there could be many different interpretations in fanfiction. It might involve a scenario where a character from the Winchester universe saves Harry Potter in some way, perhaps from a dark wizard or a dangerous situation within the magical world of Harry Potter.
I'm not sure specifically as there can be many different interpretations in fanfiction. But generally, it might involve Harry Potter being in a dangerous situation and the goblins coming to his rescue. Maybe he's facing a powerful dark wizard and the goblins use their unique skills or magic to save him.
In this fanfiction, it could be that Voldemort has a premonition. He sees that if Harry Potter dies, it will lead to a series of disasters that will also destroy his own plans. So, in order to preserve the balance or to keep his long - term goals intact, he saves Harry. For example, if Harry's death causes an uncontrollable chaos in the wizarding world, Voldemort's rule over the dark forces might be disrupted. So he steps in to save Harry.
He might use his Patronus. His Patronus could guide Harry out of a dangerous place or ward off Dementors that were about to attack Harry.
The relationship would become extremely complex. Harry would be confused and conflicted. He's been taught all his life that Voldemort is pure evil, but now he's been saved by him. Voldemort, on the other hand, might start to see Harry in a different light, perhaps as a tool or as someone with whom he can form an unusual bond. It would be a relationship full of mistrust on Harry's part and manipulative intentions on Voldemort's.
Well, it could be that William Spears has some sort of connection to an ancient and powerful magic that the 'Harry Potter' characters are not aware of. He might use this magic to create a shield around Harry Potter when he is in a life - threatening situation, like when Voldemort is about to attack. It could also be that he has the power to manipulate time and space to remove Harry Potter from the dangerous situation entirely.
The wizarding world might be in shock. People who have always seen Voldemort as the ultimate evil would be confused. They would have to re - evaluate their views on Voldemort. Harry, on the other hand, would be in a very strange situation. He might be distrusted by some of his friends who think he has made a deal with Voldemort.
Another possibility is that there is some sort of crossover magic. Maybe a spell goes wrong and links the NCIS world to the Harry Potter world. The NCIS agents, being the resourceful people they are, quickly adapt to the situation. They learn about the danger Harry is in, perhaps from Hermione who has some knowledge of both worlds now. Then they use their own brand of justice and skills to save Harry from whatever dark forces are after him.
In the 'Harry Potter Saved by Demons' fanfiction, perhaps the demons are not as evil as they seem in the traditional sense. They might be outcasts from their own demon realm. When they come across Harry, they recognize his power and the danger he's in. They decide to save him because they believe that by doing so, they can change the fate of both the wizarding world and their own world. So they use their unique demon abilities to keep Harry safe from harm.
