Well, her possessiveness might isolate Harry in a way. He may feel smothered by her actions, which could cause him to rebel or try to distance himself. This creates a new dynamic in the story where Harry's actions are influenced by trying to break free from Tonks' possessive hold, and this can lead to all sorts of plot developments like him making unwise decisions on his own or seeking out other allies who are more understanding.
One possible reason could be that she sees Harry as a symbol of hope in the wizarding world. As a hero figure, Tonks might feel the need to protect and be possessive of him to ensure his safety for the greater good.
Well, in some fanfictions, Harry might comfort Tonks by simply being there for her. He could listen to her problems, like if she's worried about her family or the situation in the wizarding world. Just his presence can be a source of comfort.
It can create a lot of tension. For example, if Harry has other friends or potential love interests, Fleur's possessiveness might lead to jealousy and arguments. This can drive a wedge between Harry and his friends or make the relationship with the other love interest more complicated.
It can create conflict. For example, if other characters don't like Jason's possessiveness, it can lead to arguments or even fights.
One of the main characters would likely be Lupin. Since he has a connection with Tonks, his presence could add a lot of drama to the story. He might suspect their relationship or even accidentally discover it. Another could be Hermione. She's always observant and might pick up on the signs of their relationship, and could either support them or be concerned about the implications. Ron could also be in the mix, perhaps being a bit clueless at first but then getting involved in some way.
Well, in such fanfiction, Voldemort's possessiveness might show through his constant attempts to control Harry's actions. He may try to isolate Harry from his friends and allies, wanting Harry all to himself in a very dark and twisted way. For example, he could use dark magic to keep Harry in a certain place or manipulate situations so that Harry has no choice but to be near him.
Fleur and Tonks might start off a bit wary of each other. Fleur, with her proud and somewhat haughty nature, could see Tonks as a bit too brash. But as they both love Harry, they would have to find common ground. They could start sharing stories about Harry's heroic deeds from their different perspectives. Eventually, they would become friends and support each other in the relationship with Harry.
There could be. Fanfiction often takes existing characters and creates new relationships and storylines for them. Since Harry and Tonks are both well - loved characters in the "Harry Potter" universe, a writer might have decided to make Harry Tonks' dad in a fan - created story. You can try searching on popular fanfiction websites to see if there are any works with this premise.
Just from the title, it gives an impression of being inappropriate. However, fanfiction often surprises. Maybe the 'sperm' part is some sort of metaphor or part of a very complex and not - at - all - vulgar magical concept in the story. But generally, it's a title that makes one question the nature and propriety of the content.
I'm not sure if Harry actually buys Tonks fanfic in the official 'Harry Potter' canon. Fanfic is a product of the fandom and not part of the original story. It could be a fun 'what - if' scenario that a fan has come up with, but there's no evidence in the books or movies to suggest that Harry would be buying Tonks fanfic.
