Well, in the fanfic, Harry might find himself in a very different power dynamic. With Tom Riddle knowing about his abuse, Harry could be pushed into a corner. He may be forced to rely on Tom Riddle for protection, which means he has to follow Tom Riddle's rules. This could lead to him losing his own sense of self and freedom. Also, the knowledge among others that Tom Riddle is involved with Harry due to the abuse situation might make Harry a target for those who oppose Tom Riddle, putting his life in even more danger.
Well, in some fanfics, Tom Riddle might initially be shocked. He could see Harry as a tool for his own purposes, and the knowledge of the abuse might make him re - evaluate how to use Harry. Maybe he decides to protect Harry in a very self - serving way, like making sure no one else can harm Harry because he has his own plans for him.
In the fanfiction world, the abusers may find themselves ostracized by the wizarding community once Viktor reveals what they've done. If Viktor has friends or allies in high places, they could ensure that the abusers are held accountable for their actions. There could also be legal consequences within the wizarding laws if the abuse is of a certain nature. For example, if it involves dark magic or illegal forms of coercion, the abusers could be sent to Azkaban or face other forms of severe punishment.
If the champions decide to take matters into their own hands, they could use magic to teach the abusers a lesson. For example, they could jinx the abusers so that they are unable to harm Harry again. However, if they report to the school, the abusers might face a formal hearing. Depending on the severity of the abuse, they could be banned from certain areas of the school, lose house points, or even be permanently removed from Hogwarts. There could also be social consequences, like being shunned by other students.
One possible consequence could be chaos. If Voldemort decides to use Harry's abuse as a reason to start attacking those he deems responsible, it could lead to a full - scale war within the wizarding world. Families could be torn apart, and allegiances would be tested as Voldemort's actions might not be seen as just by everyone.
Fleur might expose them. If they are students, they could face expulsion from Hogwarts.
In the fanfic 'Malfoy's Revelation', Malfoy is paired with Harry for a project. As they spend time together, Malfoy notices some strange behaviors from Harry, like flinching at sudden movements. After some snooping around, he discovers that Harry has been abused. This new knowledge makes Malfoy more empathetic towards Harry and he tries to help him in his own way, which includes standing up for Harry against some of their mutual enemies at Hogwarts.
After James discovers Severus' abuse, Severus may experience a range of emotions. He might be initially reluctant to accept James' help, given their history of animosity. But if he does accept, it could lead to a transformation in his self - esteem. He could start to believe that he is worthy of protection and care. In terms of his relationships at school, it could either improve his standing if the other students follow James' lead in protecting him, or it could make things more complicated if there are those who oppose James' new - found support for Severus. His academic performance might also be affected. If he feels more secure, he could focus better on his studies, but if he is dealing with the fallout of the abuse being known, it could be a distraction.
The abuser could face magical justice. In the wizarding world, there are probably spells or enchantments that can be used to punish wrongdoers. James Potter might use his connections to ensure the abuser is dealt with severely, like being sent to Azkaban or having their magic restricted.
Sirius might use magic to punish them. He could hex them or use some other form of magic to make them feel the pain they inflicted on Harry.
They might face magical punishment. For example, they could have their magic restricted or be sent to Azkaban if it's a really bad case. McGonagall would not tolerate such behavior and would push for the strictest punishment.
