If Harry owns Askzaban fanfiction, it could be that he has a passion for creating or collecting fan - made stories related to a particular aspect of the Harry Potter world that is associated with Askzaban. He might have a unique vision for this fanfiction. For example, he could be using it to explore different themes such as the nature of justice or the lives of the prisoners in Askzaban. His ownership gives him the power to decide how the story progresses, whether to share it with a wider audience, or to keep it within a certain community of fans.
Perhaps in a particular fanfiction universe, Harry has obtained the rights to Severus fanfiction. It could be that he's the one who has access to all the Severus - themed stories, like he's in charge of archiving or managing them. This might be part of a more complex fan - created plot where different characters interact with fan - made works in unusual ways.
Another interpretation could be that Harry has some exclusive rights to a particular set of Snape fanfiction within a certain fan community. For example, he might have been the first to come up with a unique plotline about Snape in the fanfiction world, and thus it's considered that he 'owns' that concept or those stories in a sense.
It could mean that in the context of fanfiction, a character named Harry is in a situation where he has possession or some sort of control over Hermione - related fanfiction. Maybe he's the author or has somehow acquired a collection of such fanfictions in the fictional world of the fanfiction.
It could mean that in the context of fanfiction, Hermione has some sort of control or possession within the fan - created stories about Harry. Maybe she is a dominant character or has a special role in those fanfictions.
It could mean that Harry, perhaps in the context of a fan-created universe, has possession of a piece of fanfiction related to Bellatrix. Maybe he has written it, or he has somehow acquired it in the world of fan-made stories.
It could mean he has the rights to certain fan - created stories related to Harry Potter. Maybe he's a collector of unique fanfiction works, or perhaps he's in a position to manage or curate a collection of such writings.
Perhaps it's a statement within a very specific context, like within a particular fan community or a new type of fan - created media. But if we assume 'ingen' is a mistake and it should be something like 'in' or 'no', then it could be about whether Harry Potter is involved in or has a relationship with fanfiction. In general, the Harry Potter series has inspired an enormous amount of fanfiction, which ranges from different time periods in the wizarding world to alternative storylines for the main characters.
It could imply in the context of fanfiction that Hermione has some sort of ownership or a significant role related to Harry's collar. Maybe it's a unique or symbolic item in the fan - created story.
It's a rather strange statement. 'Slash fanfiction' often involves non - canonical romantic or sexual pairings in fan - created stories. But the idea of Dumbledore 'owning' it doesn't make sense in the normal context of the Harry Potter universe. It could be some very niche or mis - understood concept within a particular fan community.
Well, if he owns Harry Potter slash fanfiction, it might imply that he is in control of a certain body of work within the realm of fan - made stories about Harry Potter. Slash fanfiction is a specific type of fan - created content. He could be the author who wrote it and thus owns the intellectual property of his own creation. Or perhaps he has acquired the rights to distribute or manage this particular fanfiction from the original creator.
