Perhaps a plot twist is that when Hermione is bitten, she gains a special connection to the werewolf pack. Instead of being an outcast, she becomes a sort of mediator between the wizarding world and the werewolves. This causes a stir in both communities as they have to re - evaluate their views on werewolves and those bitten by them.
Perhaps the bite leads to a rift between Harry and his friends. Some of his friends might be afraid of him now that he's a werewolf, while others might be over - protective. This could cause a lot of internal conflict within the group. Also, it could lead to Harry having to seek help from unexpected sources, like some of the more reclusive or misunderstood characters in the wizarding world who have experience with werewolves.
Well, one possible plot development could be Harry struggling to control his new werewolf nature. He might have to deal with the stigma within the wizarding world. For example, some might fear him or treat him differently. Another aspect could be his relationships changing. His friends might be initially shocked but then try to support him in finding a way to manage his condition. Maybe he also discovers new powers or abilities related to his werewolf side that he has to learn to use properly.
Perhaps the plot twist is that Naruto has to hide his new vampire nature from his friends in Konoha. This would create a lot of internal conflict for him. He might be afraid that they'll reject him if they find out. And at the same time, he has to deal with the new cravings and instincts that come with being a vampire. It could lead to some really tense and emotional moments when his friends start to suspect something is wrong.
One idea could be that in a world where werewolves are more accepted, Hermione discovers Minerva was once bitten and becomes determined to help her during the full moon. She could research new spells to ease the transformation pain.
Well, it could lead to her being ostracized by some in the wizarding community. People might fear her new werewolf nature, just like they did with Lupin. This could make her feel isolated and struggle with her identity. She might also have to learn to control her newfound instincts, which would be a huge challenge.
A plot twist might be that the werewolf gene behaves differently during the pregnancy. Instead of the usual werewolf transformation problems, it gives Hermione or Draco the ability to communicate with other magical creatures in a unique way. Also, perhaps there is a prophecy related to the baby that no one knew about before the pregnancy. This could put Hermione and Draco in a difficult situation as they try to protect their unborn child from those who might want to use the prophecy for their own gain.
A possible plot twist is that when Harry is bitten, he starts to have visions of the vampire's past. This leads him to discover a long - forgotten prophecy about a vampire - wizard hybrid saving the wizarding world. Also, his friends initially think he's turned evil due to the vampire bite, but in reality, he's just trying to figure out how to use his new state to fight the real threats in the wizarding world. It could also be that the bite makes Harry age backwards, which causes all sorts of chaos in the wizarding world as people don't recognize him and he has to re - establish his identity.
There could be a fanfic where Hermione, as a werewolf, forms an unexpected alliance with other magical creatures that are usually shunned. She uses her intelligence to break down the barriers between different species. This would add a whole new layer of complexity to the wizarding world and show Hermione's character in a different light, as she's always been one to fight for equality and understanding among all beings.
In some fanfictions, a great plot twist could be that the werewolf Hermione gets to know is actually a long - lost relative of one of her friends. This completely changes the dynamic of their relationship and adds a whole new layer of complexity to the story.
A plot twist could be that Hermione discovers she's having twins instead of one baby. This would double the excitement and also the stress for them. Ron would have to scramble to get twice as many baby supplies.
