Well, it could change their relationships in several ways. For starters, Harry could communicate with the school's owls and get messages faster. This would be really useful for his friends when they need to send urgent messages. Also, he could use his ability to understand what the magical creatures in the Hogwarts grounds are thinking. His friends could then learn a lot more about these creatures through Harry. For example, they could find out the best way to approach a hippogriff without getting hurt, which would make their Care of Magical Creatures classes much easier.
His relationship with his friends would become more intertwined with the magical world around Hogwarts. Since he can speak to animals, he might discover secrets about Hogwarts that are known only to the creatures that live there. He could share these secrets with his friends, creating a stronger bond. His friends would rely on him more for information about the magical creatures, and Harry would feel more important in their group. It could also lead to some friendly competitions, like who can find the most interesting magical creature based on Harry's conversations with the animals.
His friends would be both amazed and a bit envious. Hermione might be very interested in studying this new aspect of magic related to his ability. Ron, on the other hand, would probably be in awe and might ask Harry to use his ability to find some cool magical animals to play with. It could also make them more protective of Harry, as his ability could attract unwanted attention from those who might want to use it for bad purposes.
Harry's acceptance of his destiny would make his relationships with his friends more complex. On one hand, they would be proud of him. But on the other, they would have to adapt to his new role. His friends would need to find their own places in his journey. Hermione might focus more on researching ways to help Harry fulfill his destiny, while Ron could become more of a protector, guarding Harry from distractions. This evolution in their relationships would be a crucial part of the fanfiction's story.
Long - term, if his rebellion is for a just cause, some friends might come to understand and support him fully. However, in the beginning, it would likely be a rocky road. His relationships would be tested as he challenges the very institution that has been a big part of their lives. There could be a lot of arguments and debates among them, with emotions running high as they all try to figure out where they stand in relation to Harry's rebellion.
Hermione would probably be very interested in studying how the void - controlling ability works. She'd want to understand the magic behind it, and this could lead to a lot of discussions between her and Harry. Their relationship could become even closer as they explore this new aspect of magic together. Also, his other friends in Dumbledore's Army might look up to him more and be more eager to follow his lead in their fight against the dark forces.
His friends might be a bit worried at first. Hermione, for sure, would be concerned about the potential danger of having a snake around. Ron might be a bit scared too, considering his fear of spiders and general uneasiness around things that seem a bit dark. But if the snake turns out to be helpful, they might come around.
Telepathy likely deepens their relationships. They can understand each other on a more profound level. For instance, they can immediately know if a friend is in distress without having to say a word.
His relationship with the Dursleys would surely become more strained. He would no longer tolerate their mistreatment and might even use magic to protect himself from them if they try to continue the abuse. With his friends, it could bring them closer. Hermione and Ron would be more protective of him and would try to cheer him up when he has moments of self - doubt due to the abuse he's endured.
His learning of etiquette might initially cause some strain. His Gryffindor friends are used to his more laid - back ways. But as he becomes more refined, he starts to interact better with students from other houses. For instance, he could have more civil conversations with some of the Slytherins who value proper behavior. This could slowly change the dynamic in the common rooms and in classes, as people start to see Harry in a new light.
Well, in some versions of this fanfiction, Harry might discover it by accident. For example, he could be in a situation where he's near a dragon and instead of the usual fear or aggression from the dragon, it seems to be communicating with him in a strange way. Maybe the dragon's eyes seem to be trying to convey a message, and Harry just somehow understands it, like he has an innate sense that he can pick up on the dragon's thoughts.
His friends might be initially shocked. Hermione would be super curious and want to research all about it. Ron might be a bit jealous at first, but then come around. Their adventures would be different as Harry would have new insights from the founders.
Well, Harry's friends would have to adjust to his new role. Hermione might see it as an opportunity to learn about a whole new branch of magic. Ron, on the other hand, would probably be more interested in how Harry's powers could be useful in practical situations, like finding food in the forest. Their friendship would become deeper as they help Harry navigate his new identity as the God of Nature. They would also have to deal with the fact that Harry now has a different level of responsibility, and they would support him in fulfilling it.
