This fanfiction scenario might also change the power dynamic. Instead of Harry being the 'lone hero' figure as in the original, he might be more of a 'son following in his father's footsteps'. James would be in a position of authority and protection, which would shape their relationship in a way that is quite different from the story we know, where Harry is more independent from the start due to the lack of parental figures.
Perhaps James has more resources to take care of Harry. He could have a better living situation, more financial stability, or a stronger support system. In fanfiction, this can be a way to create a new dynamic for the characters, with James being the sole provider and protector for Harry.
The relationship dynamics change drastically. Instead of having that tragic but heroic backstory of his parents dying for him, he has a story of being left behind. This would also change his relationship with Dumbledore. Dumbledore might be more hesitant to trust Harry with the fight against Voldemort as his abandonment could indicate some instability or unworthiness in Harry's character in this fanfiction version.
Well, their relationship would likely evolve. Harry would be overjoyed to meet his parents, and Hermione would be happy for him. But at the same time, she would also be cautious and try to make sure that everything goes smoothly. They would have to work together to ensure that the meeting doesn't disrupt the fabric of the fanfiction world too much. This would require a lot of communication and trust between them, which could ultimately strengthen their bond.
The fanfiction might show a more adversarial relationship. Harry could start to oppose Dumbledore's plans instead of following them blindly. This is very different from the original where Harry was mostly compliant. For example, in the original, Harry accepted Dumbledore's tasks like finding the Horcruxes, but in the fanfiction, he might question the motives behind these tasks and resist them.
Maybe Sirius gets help from some powerful wizards or witches who believe in his innocence. They might testify on his behalf in front of the wizarding authorities. Sirius also could show his strong emotional bond with Harry. He has always been there for Harry in spirit, and now he can be there physically to raise him, which convinces the authorities to give him custody.
His relationship with Hermione and Ron might become more complicated. They might be a bit confused about this new identity of Harry. Hermione could be initially skeptical and keep trying to figure out why Harry is doing this. Ron, on the other hand, might be more accepting but also a bit worried about the potential risks.
Well, it completely flips the story on its head. In the original, James was Harry's father and Sirius was his godfather. But if they are both his parents in fanfiction, it means a different family structure. Harry might grow up with a more united front of his two dads, perhaps having a different set of values instilled in him. Also, the relationship with the wizarding world might be different as they both have their own connections and reputations within it.
Their relationship would likely become even more intimate. They are about to become parents, so there would be a new level of closeness. Harry would be more protective of Ginny, making sure she's comfortable and safe during her pregnancy.
After the kiss, their relationship takes a significant turn. They are no longer just friends who dance together. There is a new level of attraction and connection. They may start to share their secrets and fears more openly. For instance, Riley might tell James about her insecurities in dancing competitions, and James might confide in Riley about his family issues. This new - found closeness might also make them more motivated to support each other in their dance careers, as they now have an emotional investment in each other's success.
Well, if James is a Death Eater in fanfiction, it completely alters the dynamic at Hogwarts. James would no longer be part of the group fighting against Voldemort. This would mean that many of the events that happened because of the Marauders' resistance to the Death Eaters wouldn't occur. For instance, the creation of the Marauder's Map might not have been for good reasons. And Lily's relationship with James would be much more complex. Maybe she was initially trying to save him from the dark side, but failed.
