With Ron, Ron might not fully understand the condition at first. He could be a bit clumsy in his attempts to help, but over time, he would grow to be a great support. Their friendship would become deeper as Ron learns to be more empathetic and helpful. For example, Ron might initially make jokes that he thinks are harmless but later realizes they are inappropriate. Then, he would make an effort to educate himself and be there for Harry in a more meaningful way.
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.
His relationship with his teachers could also change. Some teachers, like Professor McGonagall, might be very understanding and make accommodations for him. Others, like Snape, might be less sympathetic at first but eventually come around as they see Harry's determination to overcome the challenges his epilepsy presents.
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.
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.
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.
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.
If Harry changes his look to seem more intimidating, it might make some of his enemies more cautious around him. For example, if he has a more severe look with a long beard and a scowl, the Death Eaters might think twice before attacking him. As for his friends, they might be a bit taken aback at first but would quickly accept the new look.
Well, it could make his relationships more volatile. His friends might be taken aback by sudden outbursts similar to Lily's. They may need time to adjust and understand that it's not really Harry being mean, but rather this new aspect of his personality. For example, Ron might initially be confused and a bit hurt, but as he realizes it's part of this new 'Lily - like' Harry, he could learn to handle it better and be more patient.
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.
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.
