It depends on how the author writes it. If the fanfiction is more of a comical take, Harry Potter might react in a very over - the - top way when he finds out about Jethro's nephew. He could make all sorts of wild assumptions or get into some really funny misunderstandings. On the other hand, if it's a more serious fanfiction, it could be a turning point in a larger plot. Maybe Jethro's nephew holds a key to something important in the wizarding world, and Harry's discovery of him is the first step in a long and dangerous journey to save both the wizarding world and Jethro's world from some great threat.
Since this is a fanfiction, the identity of Jethro's nephew could be completely up to the writer. He could be an ordinary Muggle who has some special connection to the wizarding world through Jethro. Or he could be a character with some hidden magical abilities that even he doesn't know about until Harry Potter discovers him.
Yes, in some fanfictions, there could be a creative plot where Harry Potter is made to be Jethro's nephew. Fanfiction often takes the liberty of creating such unexpected family relationships to explore new storylines and character dynamics.
In most traditional 'Harry Potter' lore, there is no relation to a character named Jethro. However, in fanfiction, the author has the creative license to create any sort of relationship. So it could be possible in a particular piece of fanfiction that Harry Potter is made out to be Jethro's nephew, but this is not part of the official 'Harry Potter' universe.
One possible implication is a change in family dynamics. Harry would have a new family connection that could influence his decisions and actions. For example, he might be more hesitant to engage in dangerous wizarding activities if he knew Jethro was watching out for him.
In fanfiction, the writer can create a backstory. Maybe Jethro is a long - lost relative of one of Harry's parents. For example, if Jethro was a distant cousin of James Potter, through some convoluted family tree, Harry could be considered his nephew. It's all about the writer's creativity in building a new narrative within the 'Harry Potter' universe.
Well, in such a fanfiction, Harry Potter might use the genie's wishes to defeat Voldemort once and for all. Maybe he wishes for a super - powerful magical artifact that can nullify the Dark Lord's magic.
Well, in such a fanfiction, Harry Potter might discover a magical mask with special powers. It could be a mask that allows him to see through disguises, like those used by Death Eaters. Maybe it was left behind by an ancient wizard and holds the key to some long - forgotten mystery in the wizarding world.
In this fanfiction, Harry could potentially use the lightsaber to his advantage in battles against dark wizards. The lightsaber's unique cutting ability could be a great asset. He might also face challenges like having to keep it hidden from the Ministry of Magic which doesn't recognize non - magical weapons. And there could be a whole plot about where the lightsaber came from, like if it was brought to the wizarding world by a mysterious traveler from another dimension.
Well, it could be a total chaos. The Necronomicon is a book full of dark and dangerous knowledge. Harry, being the hero he is, might be tempted by the power it offers. But he would also be very cautious as he has fought against dark magic before. He might try to destroy it to prevent it from falling into the wrong hands in the fanfiction world.
Perhaps he would be confused at first. But then, being Harry Potter, he'd be curious. He might enlist the help of Hermione and Ron. Together, they could explore the spaceship, find out where it came from and what its purpose is. They could also discover new forms of magic or technology that could change the wizarding world.
