Well, if Remus catches Harry cutting in a fanfic, it would be a really intense moment. Remus, being the empathetic person he is, would probably be shocked at first. Then he'd take it upon himself to be there for Harry. He might call for help or at least make sure Harry is in a safe environment and start to have deep conversations with him to figure out the root of the problem.
In a fanfic scenario, if Remus catches Harry cutting, he would likely be very concerned. Remus is a caring character. He might immediately try to stop Harry and find out what's wrong. He could use his calm and understanding nature to get Harry to open up about his troubles.
Well, in that situation, Sirius would be shocked and heartbroken. He might first scold Harry for doing something so dangerous to himself. Then, being the impulsive person he can be, Sirius would probably take Harry to see someone he trusts, like Dumbledore or Madam Pomfrey. He would not let Harry out of his sight until he was sure Harry was okay and not likely to do it again.
Remus would be horrified. He'd probably quickly take the cutting tool away from Harry.
Sirius would be deeply affected. He'd see Harry as a sort of surrogate family, and seeing Harry in such a state would make him feel like he failed in protecting him. He'd do everything he could to make Harry feel better, from getting him medical help to just sitting and talking with him for hours about what's wrong.
Well, it could lead to some really interesting magical adventures. Maybe Harry would have Remus in an animal form to help him with certain tasks or investigations. Remus, in his familiar form, might be able to access places that are difficult for humans to reach, providing Harry with valuable information.
In a fanfic where Harry Potter makes Remus Lupin his familiar, it could open up a whole new world of possibilities. First, it would redefine the concept of familiar in the wizarding world. Since Remus has his own complex backstory and relationships, it would add layers to Harry's character development. Harry might have to deal with the prejudice that some wizards have towards werewolves more directly. And Remus, in turn, would have a new role and purpose. He could be more protective of Harry, and they could communicate in a more instinctive way, similar to how a wizard and a traditional familiar communicate.
He might use his Patronus. His Patronus could guide Harry out of a dangerous place or ward off Dementors that were about to attack Harry.
In the fanfic, Absol might be in some kind of trouble that Ash has to rescue it from. After that, Absol decides to join Ash's team. Ash would then have to train Absol and figure out how to best utilize its skills. They could go on adventures together, facing various challenges and meeting new Pokémon along the way. Absol could also introduce Ash to new areas or Pokémon that are related to its own origin or habitat.
She might get detention. Snape is strict, and cutting class is a serious offense in Hogwarts. He could assign her to clean the potions classroom or help with sorting ingredients in the dungeon.
Ron would probably be shocked. He always looks up to Hermione as the one who follows the rules. He might try to defend her at first, but then realize she was in the wrong. Harry, on the other hand, would be more understanding. He knows that sometimes there are more important things than just following the rules blindly.
Well, they might encounter the vampires and werewolves from the Forks' lore. Harry could use his magic skills to deal with the various challenges there. Maybe he'd form an unlikely alliance with the Cullens or other local supernatural beings.
