Often, the story will focus on the search for Hermione. Her parents would be desperate and might enlist the help of the wizarding authorities. Harry and Ron, when they grow up and learn about this, could also become deeply involved in the search. There might be clues left behind by the kidnappers that lead them on a wild adventure through different magical locations.
In some fanfictions, Hermione might be raised by her kidnappers in a completely different environment. She could be taught dark magic or made to believe false things about the wizarding world. As she grows up, she starts to question her upbringing and discovers her true identity. This then leads to a conflict between her loyalty to her kidnappers and her real family and friends.
Another common development is that Hermione, despite being kidnapped, manages to develop her own magic skills in secret. She might use these skills to escape or send out distress signals. And when she finally reunites with her real family and friends, she brings with her new knowledge or powers that she gained during her time with the kidnappers, which then helps in the fight against the forces that were behind her kidnapping.
One possible motive could be power. In some fanfictions, there might be dark wizards or witches who believe that Hermione, being a very intelligent and magically gifted child even from a young age, could be used to their advantage. They might think that they can control her magic or use her knowledge for their evil plans, like finding ancient magical artifacts or unlocking powerful spells that are otherwise inaccessible.
The story could also focus on her solo adventures. She might go on a journey to discover more powerful magic or ancient knowledge that could help in the fight against the Dark forces in a way that the Order didn't consider. This could lead to her becoming a more powerful and self - reliant character.
Often, Harry and Hermione have to fend for themselves without Ron at first. They might feel betrayed and angry, but they also realize they need to be stronger. Then, they start to uncover the real reasons behind Ron's betrayal. Maybe they find out that Ron was being controlled or manipulated, and they try to save him from the dark side he has fallen into.
Often, there's a period of sadness and confusion for both of them. Hermione might try to figure out what she did wrong and reach out to Harry. Meanwhile, Harry might start to realize that he misses her friendship. Then, there could be a reconciliation scene where they finally talk things out and their friendship is restored, stronger than before.
Typically, in such fanfiction, the author might play with the idea of magical genetics. Since both Hermione and Harry are powerful wizards, the baby could be born with extraordinary magical abilities. For example, the baby might show signs of being able to perform advanced magic at a very young age. Also, the story could involve Hermione and Harry having to deal with dark forces that are interested in their child for its potential power.
Often, the story will focus on Hermione's struggle to come to terms with her new identity. She may try to find a cure at first. For instance, she might search through ancient magic texts in the library at Hogwarts.
The story might then focus on Hermione's side of things. She could feel guilty about rejecting Harry and try to be a better friend to him. Or, she might try to set Harry up with someone else she thinks would be a good match for him. Meanwhile, Harry could start to develop feelings for another character as he tries to move on from Hermione's rejection.
Hermione often shows great courage in these situations. At first, she might be scared, but she soon overcomes it. She tries to gather information about her kidnappers and their plans. If they are trying to 'adopt' her, she questions their motives and tries to find out what they really want from her. She may use her intelligence to manipulate the situation to her advantage. For instance, she could pretend to go along with their adoption idea while secretly planning her escape. She also tries to stay true to her values. If her kidnappers have a different view on things like the treatment of Muggles, she will not be afraid to speak up and defend her beliefs, even in a captive situation.
Well, it depends on the nature of the fanfiction. In some cases, the kidnapped character's friends or allies will come to rescue them. This can lead to a big battle or confrontation with sans. If sans is being controlled by someone else when he kidnaps, the rescuers might have to figure out how to free him from that control as well. Sometimes, the kidnapped character might also find a way to escape on their own, and then they have to decide whether to get revenge or try to understand sans's motives.
Well, first of all, there's the initial discovery of Snape as a baby. This causes a stir in the wizarding world. His enemies might see it as an opportunity to take advantage, while his friends (if he has any left in this state) will try to protect him. As the story progresses, there could be attempts to communicate with baby Snape, who may or may not retain some of his adult memories or magical abilities. The plot could then revolve around finding a cure, which could involve dangerous quests, ancient spells, or encounters with mysterious magical creatures. It's a really rich area for fanfiction writers to explore different aspects of the Harry Potter universe through this unique transformation.
