A great storyline could be the daughter having a unique magical ability that neither of her parents have. This could lead to her being both feared and admired at Hogwarts. In some fanfictions, she uses this ability to solve mysteries around the school. There could also be a story where she has to choose between following the Slytherin or Gryffindor values more closely, as she has a connection to both through her parents. This internal struggle can make for a very engaging read. And of course, a plot where she gets involved in a time - travel adventure related to her parents' Hogwarts years would be really exciting.
One interesting storyline could be a time - travel plot where Hermione and Draco are sent back in time and have to work with Hogwarts professors from different eras to fix a major magical disruption. For example, they might have to team up with Professors Dumbledore and Snape in the past to prevent a dark wizard from changing the course of wizarding history.
One possible storyline could be that they are forced to work together on a difficult school project at Hogwarts. They start off hating each other but gradually come to understand and respect one another as they face various challenges in the project.
One popular storyline is the 'enemies - to - lovers' trope. Draco starts off hating Hermione as in the original series, but gradually falls in love with her through various encounters. For example, they might be forced to work together on a project for Hogwarts and start to see each other in a new light.
One popular storyline could be that Draco and Hermione are forced to work together on a secret mission in the night club setting. Maybe there's a dark wizard threat that only they can solve due to their combined knowledge and skills. Another could be that they accidentally meet at the night club and start a friendly rivalry that slowly turns into something more romantic as they get to know each other better. A third one might be that they both attend the night club for different reasons, Hermione for some sort of academic research on the social behavior of wizards at such places and Draco just for leisure, and their paths cross in an unexpected way that changes their relationship dynamic.
Perhaps a storyline where Hermione is a mother in a post - war wizarding world. She has to raise her children in a society that is still rebuilding, teaching them values of peace and unity. This could involve her sharing her own experiences from the war to instill important life lessons.
One interesting storyline could be Hermione finding herself in Gotham City and having to use her magical skills to outwit the Joker. Maybe she tries to stop his evil plans without revealing her magic to the non - magical inhabitants of Gotham. Another could be the Joker getting his hands on some magical item from Hermione's world and she has to retrieve it. For example, if he got a powerful wand, Hermione would need to use her intelligence and magic to get it back before he causes chaos with it.
One interesting storyline could be where Deadpool somehow gets transported to the wizarding world. He'd be his usual chaotic self, confusing the hell out of everyone, especially Hermione. She might initially be put off by his insanity but gradually see his good side as he helps in some sort of magical - mutant mash - up adventure, like fighting a new dark wizard - mutant hybrid villain.
Often, in such fanfictions, there are plots where Hermione tries to keep the pregnancy a secret from the wizarding community at large. She might fear the reaction from both the Gryffindor and Slytherin sides. There could also be a storyline where Draco, despite leaving, has second thoughts later in life and tries to come back into Hermione's and the child's life, creating a lot of emotional turmoil.
A possible storyline is them teaming up to solve a mystery related to their family. Maybe their parents were involved in something before they were born, and now Draco and Hermione have to follow the clues. In some fanfictions, they find that their family has a connection to an ancient magic. They start to learn about their family's past together, and along the way, they overcome their initial differences. Draco's Slytherin cunning and Hermione's Gryffindor bravery combine to make them a formidable duo when it comes to unravelling the secrets.
One common storyline is the idea of Scorpius being bullied because of his family name, and Hermione and Draco having to team up to protect him. Another is where Scorpius shows an extraordinary aptitude for magic that is different from the norm, and Hermione and Draco must put aside their differences to help him develop his skills. For example, if Scorpius has an affinity for a type of magic that combines Muggle technology and wizardry, Hermione's Muggle - born knowledge and Draco's pure - blood expertise could be combined to support him.
