One interesting plotline could be that Hermione's sister is a Squib, which creates a lot of tension and different family dynamics compared to Hermione's magical abilities. It can explore how the family deals with having a non - magical member in a magical world.
Another plotline might involve Hermione being possessed by a time - traveling consciousness. This allows her to experience different eras of Hogwarts' history first - hand. She could then bring back important information from the past to help in the present, like how to defeat a powerful dark wizard that is starting to rise again in their time.
One common plotline is Hermione using the Time Turner to go back and change certain events in the wizarding world.

Another is her using it to relive certain moments with her friends, like spending more time with Harry and Ron in their earlier Hogwarts years.
Some fanfics might explore the idea of Hermione and Draco having to hide the pregnancy. Given their status in the wizarding world, it could cause a huge scandal. They might have to go into hiding, perhaps in a remote location. During this time, they learn more about each other's true selves. Draco could show his more vulnerable side, and Hermione could see that there's more to him than just the bully he was in school. And as the pregnancy progresses, they build a new life together away from the prying eyes of the wizarding community, preparing for the arrival of their child while also dealing with their own personal growth.
One possible plotline could be that Hermione discovers a dangerous curse about to befall Fred during a battle and uses her quick thinking and vast magical knowledge to counter it.

Maybe she has to solve a series of riddles to get to him first.
One possible plotline could be Astrid dealing with the mixed emotions of impending motherhood. She might be scared yet excited at the same time.

A third plotline could involve her preparing for the baby, like decorating the nursery or shopping for baby clothes.
One possible plotline could be that Harry is jealous of Hermione's academic achievements. He might see her getting all the top grades and praise from the teachers, while he struggles more in his studies. This could lead to some tension between them, but also to Harry working harder to prove himself. Another plotline could involve Hermione's popularity among their peers. Maybe she gets invited to more social events or is more well - liked, and Harry feels left out. This jealousy could make Harry re - evaluate his own relationships and how he presents himself to others.
A possible plot could be that the Goblet of Fire starts acting strangely. McGonagall notices some odd magical fluctuations around it. She enlists the help of Hermione, knowing her academic prowess. Together they try to figure out what's wrong. Meanwhile, Harry has a strange feeling about it all. Eventually, they discover that a dark wizard from the past is trying to use the Goblet to return. And they must stop it before it's too late.
Another plot could be centered around rivalry. The twin might be jealous of Hermione's popularity at Hogwarts.

This rivalry could cause some tension between them, but eventually, they would realize that they are stronger together and reconcile.
Well, a plotline could be that Fred's crush on Hermione creates some tension within the Weasley family. His siblings might notice his change in behavior around her and start teasing him or trying to play matchmaker. Meanwhile, Hermione could be completely oblivious to Fred's feelings at first. She's so focused on her studies that she doesn't pick up on his subtle hints, like the way he always offers her the last piece of treacle tart. This could lead to some comical misunderstandings as Fred tries harder and harder to get her attention.
