In fanfiction where Harry Potter only speaks Parseltongue, how does it affect his relationships with other characters?

With Hermione, she would probably be very interested in researching more about Parseltongue and how it works in Harry. She might try to find ways to help Harry control it better or understand its full potential. This could strengthen their bond as they work together on this unique aspect of Harry's magic.

One adventure could be that he is led by a magical snake to an ancient tomb. Inside the tomb are puzzles and traps that can only be solved by using Parseltongue. He has to rely on his instinct and the little knowledge he has of the snake language to progress. As he moves forward, he discovers that the tomb holds the key to a powerful magic that could either save the wizarding world from a new threat or, if misused, destroy it. Harry then has to decide whether to keep this discovery to himself or share it with his friends and mentors, all while still struggling with his limited means of communication.

With his friends, it could initially cause confusion. They are so used to calling him Harry that the new name might be a bit of a shock. But if they understand his reasons, they would likely support him. For example, Hermione might be the first to adapt and help others adjust, using her logical thinking to see the benefits of the name change.

If Harry absorbs the memories of his enemies, it could make his relationships with other characters more complicated. For instance, if he absorbs the memories of Draco Malfoy, he might understand Draco's family pressures better. This could lead to a more complex relationship where Harry has both sympathy and still some animosity towards Draco.

His relationship with Ginny might be affected. Ginny could be very protective of him and worry a great deal. This could lead to some sweet, tender moments between them as she takes care of him during his seizures.

In this fanfiction scenario, Harry's relationship with Dumbledore could be very interesting. Dumbledore would surely be aware of the significance of Excalibur. He might take Harry under his wing even more, guiding him on how to use the sword's power for good. Harry's relationship with the other Hogwarts students could also change. Some might look up to him even more, while others might fear him because of the great power he now wields.

If Harry is sleepwalking, it might worry his friends. For example, Hermione would probably be very concerned and try to find a way to stop it. This could strengthen their friendship as she devotes time to helping him. Ron, on the other hand, might initially find it funny but then also realize the seriousness. It could also make some of his classmates more curious about him, which could either bring them closer or create some distance depending on how they react to his sleepwalking episodes.

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 relationships with his teachers could also change. Dumbledore might look at Harry with more sympathy and offer him different kinds of guidance. Snape, although still prickly, might secretly respect Harry more for enduring this new hardship, or he could use it as an excuse to be even more critical, thinking that Harry is now more likely to make mistakes.

His intelligence might make him more respected by his peers. Instead of just being known for his scar and his connection to Voldemort, his friends see him as a true intellectual. Hermione might become more of an equal to him in terms of academic discussions rather than just being the one who always has the answers. Ron, on the other hand, could feel a bit intimidated at first but then grow to be proud of his friend's intelligence.
