In the 'hermione forgets she's married to harry fanfic', how could such a plot device be interestingly developed?

One way it could be developed is through a powerful dark magic influence on Hermione. Maybe Voldemort discovers a way to manipulate her mind using a long - forgotten spell. This could cause her to gradually turn against her friends and side with him. For example, she might start to believe in Voldemort's ideas of pure - blood supremacy after her mind is clouded.

In a fanfic like this, the plot could develop around Hermione's discovery of her true parentage. She might initially be in denial, but as she starts to notice certain similarities between herself and Voldemort, like an unexpected proficiency in certain dark spells or a strange pull towards the Dark Lord's old haunts. It could also create a huge rift between her and her friends in Hogwarts. They might be suspicious of her, and she would have to prove that she is still on the side of good despite her blood relation to the most evil wizard of all time.

In a fanfiction where Hermione forgets she's a witch, it would be a huge disruption to the normal order. She has been such an important part of the wizarding world. Her forgetfulness could mean that she no longer has the confidence she once had. She might start to doubt herself and her place in Hogwarts. This could lead to her being bullied or taken advantage of by some of the less - friendly characters. However, it could also be a chance for her to grow in a different way, perhaps by relying more on her non - magical skills and learning about the wizarding world from a completely new perspective.

One way could be through a misunderstanding. Maybe they believe Hermione has done something wrong, like they misinterpret her actions regarding a dangerous spell she was researching. So they distance themselves from her, which she sees as a betrayal.

One way is through forced proximity. For example, they could be stranded together on an island. At first, they'd be at each other's throats due to their past enmity. But as they struggle to survive, they start to see different sides of each other. Small acts of kindness, like sharing food or protecting each other from wild animals, gradually chip away at their animosity. Eventually, the sexual tension builds as they become more comfortable in each other's presence and start to develop feelings beyond hatred.

It could be a spell gone wrong. Maybe some dark magic or a misfired charm affected her memory. It's not uncommon in the wizarding world for things like this to happen.

Maybe in the fanfiction, Voldemort devises a plan where Snape forgets Harry to disrupt the Order of the Phoenix's plans. Without Snape's knowledge of Harry and his role in the prophecy, things start to go awry. Harry has to find a way to make Snape remember, perhaps by going on a quest to find a magical relic that can restore memories. Hermione and Ron would be by his side, of course, providing their usual support and knowledge.

In fanfic, their daily routines might include waking up early. Harry could be making them a simple breakfast while Hermione reads the morning paper. They would likely discuss magical research Hermione is doing or the state of the wizarding world. In the evenings, they might sit by the fireplace and share stories of their Hogwarts days.

In Harry Potter fanfic, Parseltongue can be a powerful plot device in many ways. Imagine a fanfic where the dark forces are using Parseltongue to communicate their evil plans. The hero, who also happens to be a Parselmouth, overhears them and has to find a way to stop the plot without being discovered. Or perhaps a fanfic where an ancient prophecy is written in Parseltongue, and the characters must decipher it to save the wizarding world. It can also create interesting relationships between characters. For example, two Parselmouths from different sides of a conflict might have a unique connection through their shared ability, which could lead to unexpected alliances or betrayals as the story progresses.

The plot could develop by introducing a character who challenges Percy's decision. For example, a new girl who is not deterred by his 'no - love' stance and slowly makes him question his own beliefs. This would create an interesting dynamic as Percy tries to resist but finds himself drawn to her.
