A plot twist could be that when Draco falls off his broom, instead of Hermione helping him directly, she uses a spell to make his broom catch him at the last moment. This shows her intelligence and also makes Draco question her motives. Later, he discovers that she didn't want to expose their growing friendship to others. Another twist could be that Draco's fall was actually a planned thing by someone who wanted to harm him, and Hermione has to figure out who it was while taking care of Draco. This adds a mystery element to the story.
In some fanfics, Draco's fall off his broom might be a result of a curse placed on him. Hermione, instead of using her usual magic to save him, has to use a dark magic - countering spell that she has been researching in secret. This reveals a side of Hermione that Draco didn't expect. And as Draco recovers, he becomes protective of Hermione because he realizes that if others knew about her knowledge of dark magic counter - spells, she could be in danger. This completely changes the dynamic between them and sets the story on a new path.
One possible fanfiction could be where Draco is showing off on his broom during a Quidditch practice. He tries a particularly risky move to impress Hermione who is watching from the stands. But his broom malfunctions and he falls. Hermione, being the kind - hearted person she is, rushes to his aid and this incident becomes a turning point in their relationship, making them see each other in a new light.
In some fanfictions, his fall off the broom could be a turning point in the story. It might lead to him discovering a new magical ability. For instance, he could unconsciously use a form of magic to slow his fall or even levitate himself slightly. This newfound ability could then be explored further in the story, perhaps making him a more powerful wizard in unexpected ways.
He could get seriously injured. In some fanfictions, he might break a bone or two. It would also likely lead to him being out of the Quidditch match if it happened during one.
In certain fanfictions, Harry's fall could be a part of a larger conspiracy. Maybe someone tampered with his broom on purpose. This would then lead to an investigation, with Harry and his friends trying to figure out who was behind it. Along the way, they could uncover other secrets about Hogwarts or the wizarding world in general, which would add more depth and complexity to the plot.
Dumbledore could also be a savior. Given his powerful magic, he could easily appear at the scene and use a spell to stop Harry from hitting the ground too hard. Or perhaps one of the teachers at Hogwarts, like Professor McGonagall, who is strict but caring, would use her transfiguration skills to create something to break his fall.
They could be racing each other on their brooms. Lucius, with his more experience, might initially be in the lead, but Draco, being young and eager, could use some new - fangled trick to overtake him.
Perhaps it's a story where Draco is learning how to fly better from his father Lucius. Lucius could be showing Draco some advanced flying techniques while they are on the broom, and during the flight, they might have a deep conversation about the family's future in the wizarding society.
Well, one interesting plot point is the initial shock and confusion for Draco. For example, in many of these fics, when he first realizes he can read women's minds, he's bombarded with all kinds of thoughts that he wasn't prepared for. Another plot point is how it affects his relationship with Hermione. He might discover her insecurities or her true feelings for him, which can either bring them closer or create more conflict depending on how the author writes it. Also, there could be a plot point where Draco has to keep his ability a secret from others in the wizarding world, and the stress of that secrecy can add an extra layer of drama to the story.
Another possibility is that Draco falls in love with a character from the opposing side. His love could be so strong that it overrides his loyalty to his original side, leading him to change. For example, if he falls for a Gryffindor, he might start to see things from their perspective and gradually shift his allegiance.
One interesting plot twist could be that Ginny and Draco's pregnancy is a result of a magical accident. Maybe a spell gone wrong during a battle or an experiment that binds their magical essences together. Another could be that they keep the pregnancy a secret from everyone at first, and as they struggle to come to terms with it, they start to develop unexpected feelings for each other. For example, Draco, who has always been a bit of a snob, realizes Ginny's true strength and kindness through this situation. And Ginny sees a more vulnerable side of Draco that she didn't expect.
