The therapist might first try to create a safe and comfortable environment for Harry. Since he's used to secrecy in the wizarding world, the therapist would need to assure him of confidentiality. Then, they would likely start by asking him about his recent experiences, like his nightmares related to Voldemort.
It could be a new character, a wise old wizard who has studied Muggle psychology and combines it with magic to help patients. For example, he might use spells to calm the patient while using talk - therapy techniques.
Harry would begin by relying on his intuition and his knowledge of magic. He'd remember all the times he faced difficult challenges and how he overcame them. He'd start by casting a protective charm around himself and the area to prevent any accidental petrification. Then, he'd use his wand to send out a wave of magic to sense the source of Medusa's problem. If it was a curse, he'd look for counter - curses in his vast knowledge of magic. He might also try to find a way to temporarily nullify Medusa's petrifying power so he could work more closely. He'd be patient and persistent, constantly adjusting his approach as he learns more about what is needed to heal her.
He could be shocked. Maybe there are some fanfictions that take a very dark turn or have unexpected pairings that he never thought of. He'd probably need some time to process such strange ideas. And he might also be curious to see how far the creativity of the fans can go. He might even get some new ideas about his own life from reading some of the more imaginative fanfictions.
The magical world would have to be very secretive. They might have agents in every major city to keep an eye on any magical accidents that could expose them. For instance, if a wizard accidentally made a car fly in the middle of a busy street.
One possible plot could be that Harry has PTSD from all his battles and the loss of loved ones. The therapist helps him deal with his nightmares and survivor's guilt.
He might feel a bit embarrassed. After all, these are often people's wild imaginings about his personal life.
The fandom would be divided. Some fans who are deeply into fanfiction would be disappointed and might feel like a part of their connection to the 'Harry Potter' world has been cut off. However, others who are more focused on the official works might not be as affected. There would likely be a decrease in the variety of fan - created stories, which could limit the creative exploration within the fandom.
The characters would change a great deal. Harry, for example, might be less of the pure - hearted hero. He could have a more cynical view of the world around him, similar to Brightburn. Hermione might be more distrustful of Harry's new - found darker tendencies. Ron could be more afraid of Harry and his powers, which would strain their friendship.
Well, in Harry Potter fanfiction, he could be in any kind of world. Maybe a world where wizards rule openly, or one where magic is fading away. It's really up to the creativity of the fanfic writer.
The Ministry of Magic would likely be in chaos. They would try to find a way to stop the spread and hold Harry Potter accountable. There would be a lot of panic among the wizards and witches, with many trying to flee or find a cure on their own.
