Some of the more traditional pure - blood families in the wizarding world could be antagonists. They might not approve of Harry, a half - blood, being involved with Pansy, and they could try to stop the pregnancy or break up the couple for the sake of 'pure - blood' ideals.
Well, in such a fanfiction, there could be a lot of chaos. Maybe Harry would first be in shock and then have to face the reality of becoming a father at a young age. It could also lead to a huge rift between him and his friends who might not approve of his relationship with Pansy.
One possible scenario in a Hermione and Pansy pregnant fanfiction could be that they are both part of a magical experiment gone wrong that results in their unexpected pregnancies. This could lead to a whole new set of challenges as they are from different houses in Hogwarts and might have different outlooks on life.
One possibility in this fanfiction could be that Draco and Pansy's pregnancy is a result of a long - hidden love. Maybe they had always had feelings for each other but were too proud to admit it earlier. Their pregnancy could be a turning point in their relationship, forcing them to face their emotions and the responsibilities that come with having a child. It could also lead to interesting interactions with their families, especially considering the pure - blooded nature of both families in the Harry Potter universe.
One idea could be that they are forced into an arranged marriage in a post - war world where they have to put aside their old grudges. Pansy discovers she's pregnant, and they both struggle to adapt to the new situation. Harry, being the hero he is, tries to protect Pansy and the unborn child from any threats.
For Harry, he could start as being very hesitant about the whole situation. He still has his Gryffindor ideals and is not sure about marrying a Slytherin. But as he spends time with Pansy, he could become more open - minded. Pansy, on the other hand, could start as cold and distant. But as she gets closer to Harry, she could show her more vulnerable side, like her fear of not being good enough.
Hermione could be a common character. She might be initially skeptical or even opposed to the idea of a harem but eventually come around. Another could be Draco. His relationship with Pansy and his past enmity with Harry could add a lot of tension and intrigue to the story. Also, Ginny could be in it, perhaps trying to win Harry back or having to accept the new situation.
There could be a fanfiction where Hermione and Pansy are pregnant due to a time - travel mishap. They end up in a different era in the wizarding world where their pregnancies are even more of a shock. They have to rely on each other for support as they are outsiders in this new time. Along the way, they discover new magical abilities within themselves that are related to their pregnancies. This not only helps them survive in this new era but also changes their relationship for the better as they see each other in a new light.
Harry may become more understanding of the Slytherin mindset. He realizes that not all Slytherins are bad, especially as he gets to know Pansy better through the marriage contract. He might start to see the value in their ambition and cunning in a different way.
The relationship between Harry and Pansy would be at the center of this change. They would have to form a new bond based on the fact that they are about to become parents. Their relationship might start off rocky but develop into something deeper as they face the challenges together. Meanwhile, the relationship between the Gryffindor and Slytherin houses in general could be affected. There could be more animosity or, in some cases, a new understanding as a result of Harry and Pansy's situation.
