One common plot twist in Hermione and Harry jealous fanfiction is when there's a misunderstanding.

One plot twist could be that Hermione's jealousy is actually part of a spell cast on her. An enemy of the trio wants to create discord between them, so they cast a spell that magnifies her normal competitiveness into full - blown jealousy. As the fanfiction unfolds, she starts to realize her feelings are not normal and with the help of her friends, she breaks the spell. Or perhaps, Harry's grades are part of a prophecy - related phenomenon. Hermione's jealousy then takes a backseat when they realize the greater implications of Harry's academic success in relation to the prophecy.

In a particular fanfiction, the disease seems to target only pure - blood wizards. This causes a huge uproar in the wizarding community as they suspect it's a plot by Muggle - borns.

The plot twist lies in the fact that the solution is not about blood purity but about restoring the balance of an ancient magic that the artifact disrupted. It's a great exploration of the themes of prejudice and unity in the HP world.
