How would Harry's relationship with his friends change if he found out he had a twin in fan fiction?

Well, Percy's relationship with his friends would likely become more complex. If his twin brother was a bit of a troublemaker, Percy's friends might be divided in their opinions. Some might want to give the twin a chance, while others, like Grover, might be more worried about how the twin's actions could affect Percy. On the other hand, if the twin was really helpful and kind, Percy's friends would probably welcome him wholeheartedly, and Percy would have an even stronger support system within his group of friends.

His life would become more complex. He would have a new family bond to consider. He'd likely be more protective and might start to think about his future in terms of his sister as well.

If Harry met his parents in fanfiction, his relationship with his friends might become even stronger. His friends would be happy for him, and they could all share in the newfound family bond. Harry might be more confident and self - assured, which would make him a better friend. He could also introduce his friends to his parents, and his parents could give his friends some advice or magical gifts, strengthening the whole group's connection.

Some of his friends might be very supportive. Hermione, for example, would probably offer a lot of practical advice on how to raise a child properly. Ron, on the other hand, might be a bit more hesitant at first but would come around. Overall, they would likely become closer as they help Harry with this new responsibility.

They might be a bit surprised at first. But then they would probably be understanding. Hermione, for instance, might be interested in the literary aspects of the fanfiction he likes. Ron, on the other hand, might tease him a bit but still support his interest.

It could change in several ways. If Merlin's twin sister is also part of Arthur's court, Arthur might be more protective of both of them, seeing them as a pair. Or, he could be more suspicious of Merlin if his sister has a different approach to magic. Maybe she's more open about it, which makes Arthur question Merlin's secrecy.

His friends might be in awe of him at first. Since Harry would be learning from Merlin, he'd likely gain new and extraordinary abilities that his friends would find both amazing and a bit intimidating.

Snape's view of Harry might become more sympathetic. He would see Harry as a victim rather than just an annoying student. This could lead to a softening of his attitude towards Harry in general.

They might start to see Harry as a victim rather than just an enemy. Their view of him could become more sympathetic.

Harry would likely be quite curious. He'd want to know what these fanfictions were about. Maybe he'd be a bit cautious at the same time, worried that some of the fanfictions might distort Sirius's true character. But overall, I think he'd be intrigued and might even try to find a way to read some of them, just to see what the fuss was all about.
