The resemblance might also affect Harry's romantic relationships at Hogwarts. For example, if he had a budding romance with Ginny, Ginny might have some mixed feelings. On one hand, she loves Harry for who he is, but on the other hand, the visual reminder of Voldemort in Harry's appearance could cause some unease. Some other students who had crushes on Harry before might lose their interest, while new students who are intrigued by the mystery of his appearance might be attracted to him. Overall, it would create a lot of complex emotions and changes in how people interact with Harry at Hogwarts.
His relationship with Ron would likely become strained. Ron, who values loyalty and friendship above all, would be put off by Harry's new - found Riddle - like behavior. Harry might start to see Ron as beneath him or not as useful, similar to how Riddle treated his less - than - worthy followers. With Hermione, she would probably try to reason with Harry at first. But as he continued to act like Riddle, she would become frustrated and might distance herself, as she would see the danger in Harry's new attitude.
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.
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.
His relationship with the teachers might become more complex. Some teachers might respect his newfound authority over the wards, while others might be wary. For example, Snape might be suspicious of Harry's intentions.
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.
His friends might be initially shocked but then find it hilarious. Ron would probably tease him good - naturedly. Hermione, on the other hand, would be more concerned about how to reverse it at first but then accept it as part of Harry's new look. Some of his Slytherin rivals might use it as an excuse to taunt him more, thinking he looks ridiculous.
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.
