It could mean that in a Harry Potter fanfic, there's a character who is not considered part of a particular group within the fanfic's story. Maybe he has different values or goals compared to the rest of the characters who are united by something specific in the fan - created story.
Well, in the context of a Harry Potter fanfic, 'he is not one of us' might imply that this 'he' doesn't belong to a certain clique or faction. It could be related to Hogwarts houses, for example. If it's a group of Gryffindors in the fanfic, and 'he' is acting in a way that's not in line with Gryffindor values, then they would say he's not one of them. It could also be about a secret society within the fanfic's version of the wizarding world.
It could be an older wizard who has turned his back on the traditional ways that the group in the fanfic adheres to. Maybe he has discovered a new form of magic that is considered taboo by the others, and so they see him as an outsider, not one of them. He might also be trying to bring about changes in the wizarding world that the group is not ready to accept, such as more integration with non - magical people in the fanfic's story.
Well, 'Harry Potter' is the famous series. 'Trust no one' is a common theme in many stories, especially in a world like Harry Potter's where there are a lot of secrets and betrayals. A 'fanfic' is a fan - created fiction. So it could be a fan - written story in the Harry Potter universe where the main idea is about not trusting anyone.
Well, 'scourgify' is a spell in the Harry Potter universe that cleans things. In a fanfic, 'scourgify power he knows not' could imply that a character is unaware of the full potential or some hidden aspect of the scourgify spell. Maybe it could be used in a more powerful or different way than the character realizes.
It could be Harry Potter himself. He's always been one to help others, especially those in need. He might see a new student being harassed by Slytherins and step in, saying 'one of us will help you'.
A 'fanfic' is a fan - created fiction. 'Metamorph' could imply something related to transformation. So it might mean that this fan - created work about Harry Potter focuses on transformation elements in the Harry Potter universe.
It could mean that within the context of the Harry Potter world, there is an idea or statement where Harry Potter, as a character, is opposed to fanfiction. Maybe it implies that the official or 'true' story as per the original works doesn't want to be overshadowed or misrepresented by fan - created stories.
It could potentially mean that in some sort of extreme or alternate take on the Harry Potter universe, the character Harry Potter is involved in actions that put an end to fan - created fictional works. Maybe it implies that his actions in a particular story disrupt the fanfic narrative in a very drastic way.
Well, it might be a really unique take on fanfiction. Maybe in this fanfic, the concept of the Capulet family's story in 'Romeo and Juliet' has some sort of allure for Harry Potter. It could be that the author is trying to blend the magic and drama of the wizarding world with the classic tragedy of the Capulets. For example, perhaps Harry discovers a parallel between the power struggles in the wizarding world and those within the Capulet family in Verona.
Well, 'disabled' here might refer to a character in the fanfic being disabled. In Harry Potter fanfic, it could be a story where a character, perhaps someone new or an existing character like Harry himself, is disabled. It could explore how they deal with magic, Hogwarts life, and all the challenges in the wizarding world while having a disability.
Well, it could be a very strange or dark take on a Harry Potter fanfic. 'On suppressants' might imply that in this fan - created story, Harry Potter is somehow being drugged or having his abilities suppressed, but it's a really odd and not very common concept in the typical Harry Potter fanfic world.
