What Are the Common Plot Twists in Hermione and Draco as Brother and Sister Fanfics?

A common plot twist is that Draco is secretly working against his family's wishes to protect Hermione. For example, his family might be part of a dark plot, but he chooses to side with Hermione instead. This adds an element of conflict and drama to the story.

One interesting plot twist could be that despite being siblings, they are sorted into different houses, and this causes a rift in their relationship initially. But as the story progresses, they find common ground in their magical abilities and family secrets.

A common plot twist is that Hermione actually has a hidden power or ability that she reveals during her captivity. For example, she might be able to use a type of magic that Draco and his associates didn't expect, which gives her an upper hand in the situation. This could lead to a change in their relationship dynamic, from captor - captive to something more like equals.

One common plot device is Draco flirting with other girls in front of Hermione. For example, he might shower another girl with compliments about her magical abilities which Hermione takes as a personal slight since she prides herself on her own skills. This immediately makes her jealous and sparks a series of events where she tries to show Draco that she doesn't care, but actually does.

One interesting plot twist could be when Hermione discovers her true heritage and has to face the fact that she's related to the Malfoys. It completely changes her relationship with Draco. Instead of being enemies, they have to figure out how to be siblings in a world where their families have such different values.

Often, a plot twist could be the discovery that the baby is part of some ancient prophecy. This throws Draco and Hermione into a whole new set of challenges as they try to protect their child and fulfill the prophecy. Also, there might be a plot twist where Hermione's Muggle - born status causes problems. Some in the wizarding world might try to use the new baby as a way to target Hermione and her family again, despite her relationship with Draco.

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 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 plot twist is that the child has some extraordinary magical power that neither Hermione nor Draco expected. Another is that the secret of the child's existence is threatened to be exposed by an old enemy. Sometimes, the child may turn out to be the key to solving a big mystery in the wizarding world.

Another theme is the changing of relationships. Their relationship, which was mostly adversarial in the books, takes a new turn. It can range from friendship to a more romantic relationship. For example, in many fanfics, the act of saving Hermione makes Draco realize his feelings for her that he had been suppressing.
