Their relationship could turn into a bitter rivalry again. Maybe they both regret the one - night stand immediately. Hermione might think Severus took advantage of her in a moment of weakness, and Severus might think Hermione was just being a silly Gryffindor. This would cause them to start arguing and competing again, but this time with an added layer of personal animosity from the night that they shared.
Their relationship would likely become more centered around the baby. They would have to cooperate even more closely to take care of the little one. There would be less time for their own personal issues as the baby's needs would be top priority.
During the pregnancy, their relationship would deepen. Severus would use his knowledge to take care of Hermione, like making special potions for her well - being. They would have to communicate more about their future and the baby's future. They might face some challenges, like Severus' past reputation causing some issues, but they would work through them together, growing closer in the process.
After the one - night stand, they might face a lot of opposition from their friends and families. Draco's pure - blood family might not approve of his relationship with Hermione, a Muggle - born. But this external pressure could actually bring them closer. They could fight against the odds together, and in the process, their relationship could transform from a one - night stand into a strong, loving relationship.
At first, it might be a bit rocky. Hermione is very opinionated and Severus is, well, Severus. But as she grows, she could start to see past his prickly exterior. Maybe she discovers his hidden kindness through his actions towards her in the fanfiction.
In fanfiction, the vampire side of Severus can make their relationship more intense. It can introduce a forbidden - love - like quality. Hermione is a rule - following Gryffindor, and being involved with a vampire goes against many norms. This creates a lot of internal and external conflict. Their relationship is no longer just about their personalities but also about this huge, vampiric secret. And it often leads to some really exciting plot twists as they try to keep their relationship hidden or find a way to make it work in a world that may not accept it.
In the long run, their relationship could either turn into a loving family unit or they could go their separate ways completely. It depends on how they handle the various challenges that come with the pregnancy. If they communicate well and are willing to forgive past mistakes, they might build a strong bond. But if they keep holding grudges or have different life goals, the relationship could fall apart.
Well, it would change the story a great deal. Firstly, Harry would have a more stable home environment with Severus as his guardian. He wouldn't be so alone at the Dursleys'. Draco, on the other hand, might learn different values from Severus rather than just pure - blood supremacy from his family. And Hermione would have an adult figure in the wizarding world who truly understood her thirst for knowledge. The whole dynamic between the three of them would shift from rivalry to more of a sibling - like relationship under Severus' care.
After marriage, they'd likely become more in - sync. They'd understand each other's quirks even better. Draco might become more open - minded due to Hermione's influence, and Hermione would learn to relax a bit more with Draco's laid - back Slytherin side. Their relationship would be a balance of Hermione's drive for knowledge and justice and Draco's sense of family and loyalty.
In the beginning, Severus would probably view Hermione as a nuisance. But Hermione, being Hermione, would not take being treated like a simple pet lying down. She would constantly challenge him in small ways, like refusing to follow his commands in a way that made him think. This would pique Severus's interest. As they spent more time together, he would come to respect her and see her as more than just a pet. Their relationship would develop into a complex one, with elements of friendship, respect, and a shared love for knowledge.
Their relationship might start off very rocky. Severus would be distrustful of Hermione as she is a Gryffindor and he has his own prejudices. But as they are forced to rely on each other because of the Time - Turner situation, they start to see each other's strengths. For example, Hermione's intelligence and quick thinking, and Severus' knowledge of magic and his ability to be cunning in difficult situations.
