Some of his friends could be skeptical about whether it's really Harry. After all, coming back from the dead is a very rare and almost unheard - of thing in the wizarding world. This could lead to a period of testing and proving his identity, which would strain their relationships at first. But once they are convinced, they would have to deal with the new Harry who has been through the experience of death.
Harry's return could also bring up old unresolved issues among his friends. Maybe there were things that were left unsaid or arguments that were never fully resolved before his 'death'. Now that he's back, these issues might resurface and they would have to work through them while also dealing with the fact that he's alive again.
His friends might be overjoyed at first. But then, they could also feel a bit of unease. For example, Hermione might be worried about the implications of his return and how it fits into the laws of magic they know. Ron, on the other hand, might be more focused on just having his friend back and want to jump right back into their old adventures.
It could strengthen their bond. They could sit together and laugh about the crazy ideas in the fanfiction. Sharing this experience of reading about themselves in different scenarios would give them more things to talk about and joke around with.
Hermione would be overjoyed. She'd probably start researching immediately how it happened and what implications it has for magic. Ron would be both happy and a bit in awe, like he was when they first became friends with Harry. For Ginny, it would be a huge relief and she'd be very emotional, as she lost the love of her life.
It would strengthen their bond. His friends would be in awe of Harry for catching such a dangerous and elusive figure. They would see Harry as even more of a hero, and it would bring them closer together as they deal with the aftermath. For example, Hermione would be eager to research all about Peter and what his capture means, and Ron would be proud to have Harry as his best friend even more.
Some of his friends might feel abandoned. For example, Hermione, who has always been by his side, could initially be hurt. But she would also understand his need for a new start. Ron, on the other hand, might be more confused and might take some time to accept it.
The return of the dead can also cause conflict among the characters. Some might be skeptical or even afraid of the resurrected character. They could think it's some sort of dark magic at play. Take Hermione for instance. She might be initially cautious and want to investigate how and why the character has returned, which could lead to tension within the group of friends.
His friends would likely be devastated at first. Hermione, for instance, might throw herself into research to find out what really happened, believing there has to be a way to bring him back. Ron would be in a state of shock and anger, feeling like he failed to protect Harry. They would probably also start to question their own actions and whether they could have done something differently to prevent Harry's 'death'.
It might make his friends a bit wary at first. Since this is an unusual and powerful thing to happen, they could be concerned about how it's changing Harry. But as they see that Harry is still the same person deep down, they would gradually accept it.
His friends, like Ron and Hermione, would be quite surprised. Ron might be a bit jealous at first that Harry has this unique experience of traveling back in time. But then they would realize the potential of it. Hermione would be eager to make sure Harry doesn't change things too much that could have a negative impact on the future.
His friends would be overjoyed at first. But then they might start to feel a bit of unease. They've moved on in some ways since his death, and Naruto's resurrection could disrupt that. For example, Sasuke might have to re - evaluate his feelings towards Naruto and their rivalry.
Well, it depends on how the fanfiction portrays it. In some cases, his friends could turn against him completely. They might see him as a danger to the wizarding world. But in more positive portrayals, they would see this as just another challenge for Harry to overcome. They would be there for him, but it would be different. For instance, they might have to help him find new ways to do magic since the vampire bite could potentially affect his magic in some ways. Their relationship would be a mix of loyalty and a new kind of understanding as they all deal with this unexpected change in Harry.
