In the 'Harry Finds Out Blaise Is His Brother' fan fiction, how does Harry react to this discovery?

Maybe a magical accident or a powerful spell that revealed the truth.

Harry might be initially shocked. He has been brought up in the wizarding world with certain beliefs and Fenrir is a werewolf, a feared and often misunderstood being. So, his first reaction could be disbelief. He might question how this could be possible considering their different natures.

He might be initially shocked. After all, he has always seen Hermione as a friend, and suddenly finding out she's his twin would turn his world upside down. He could feel a mix of confusion, excitement, and also a bit of unease as he tries to understand how this could be possible and what it means for their relationship and his own identity.

He might be shocked at first. Discovering that he isn't a Potter is like shattering his whole identity. He could feel lost and confused, not knowing who he really is anymore.

He might be shocked at first. Since Lucius is a complex character, he could initially see it as a weakness in Harry that he could potentially use to his advantage in the wizarding world's power games.

Well, it really depends on the specific characteristics of the champion in this fanfiction. If the champion is a very impulsive and kind - hearted person, they might confront the abuser right away. But if they are more calculating, they could gather evidence first. They would also probably feel a sense of responsibility to help Harry, given that they now know about his situation. They might offer Harry a place to stay, or try to get the proper authorities involved in the wizarding world to deal with the abuser.

Draco might initially be shocked. He could then feel a sense of protectiveness towards Harry. Maybe he starts to see Harry in a new light, not as his rival but as someone who needs help.

Some in the wizarding world might be very accepting. After all, soulmates are considered a special and magical thing. But there could also be those who are more traditional and might not understand how two guys could be soulmates. They might gossip or spread rumors, but the true friends of Harry and Fred would stand by them.

Draco Malfoy himself would be very surprised if he found out. He might initially think it's some kind of joke or a ploy to embarrass him. But as he realizes Harry is sincere, he could be conflicted. On one hand, he's been taught to dislike Harry, but on the other, this new revelation could make him see Harry in a different light too. As for the other Hogwarts students, some might be amused, while others who are more loyal to the traditional Gryffindor - Slytherin divide might be appalled.

Ron might be shocked at first. He could become very protective of Harry, standing up for him against any potential threats. Maybe he would also be a bit angry that he hadn't noticed earlier.
