The relationship would change drastically. They would no longer be just former enemies or reluctant allies. They would become co - parents. Harry's natural inclination towards kindness and Severus' protective nature (although often hidden) would come to the fore. They would have to learn to trust each other completely, which would be a difficult but necessary step. There would be arguments and misunderstandings, but also moments of deep connection as they raise their baby in the magical world.
At first, it would be extremely strained. Severus has a history of being at odds with Harry. But with the baby in the picture, they would be forced to interact. Harry might see a different side of Severus as he tries to be a father. Severus, on the other hand, would have to deal with his own feelings towards Harry while also caring for the baby. Over time, they could develop a bond based on their shared responsibility and the love for their child. This would be a huge transformation from their previous relationship which was full of mistrust and dislike.
Severus would likely become more protective. His personality would shift from being mainly focused on his own grudges and potions work to being centered around Harry's well - being. He might also become a bit more open - minded as he has to consider Harry's needs and wants, which could be different from his own. For instance, he may have to tolerate Harry's love for flying, even though he himself may not be into it. And over time, he might develop a sense of humor as he deals with Harry's childish antics.
At first, their relationship would be full of hostility. Harry would be angry about being forced into this marriage with Severus, who he has had a complex history with. Severus, on the other hand, might be indifferent or even disdainful.
In many of these fanfictions, Severus becomes more empathetic. For example, in 'A Different Destiny', when he finds baby Harry, he starts to see the potential for a different future for the boy, which makes him less bitter and more open - minded.
One popular one is 'A Different Destiny' where Severus finding baby Harry sets off a chain of events that deviate from the original story's path. It has great character development.
His personality also becomes more open. He has to communicate with Harry in a more honest and open way. He can't keep all his thoughts and feelings bottled up like he used to. He has to share his wisdom and experiences with Harry, which in turn makes him more approachable and less of the brooding, closed - off person he was before in the official story.
At first, it's likely to be full of tension. Harry may be hesitant and even a bit resentful about the marriage, while Severus is his usual cold self. But as time passes, they start to see each other's good sides. Harry realizes Severus's intelligence and Severus sees Harry's courage in a new light.
He would become more nurturing. Usually, Severus is seen as cold and aloof, but with Harry in his care, he'd have to show more warmth. He might still be strict, but it would be out of love for Harry's well - being rather than just being his usual harsh self.
In these fanfictions, they often explore the relationship by delving into the power dynamics at play. Severus, being a former Death Eater and a teacher, has a certain authority. Harry, on the other hand, is the Boy Who Lived. The lemon aspect adds a layer of passion and physicality. For example, in some stories, the initial animosity between them slowly turns into a more complex attraction. The fanfictions may use their shared experiences, like fighting Voldemort, as a backdrop to build this unique relationship.
The relationship may become more complicated. Severus might struggle with his own emotions. He might feel an urge to protect Harry from this fictional abuse, but at the same time, he has to deal with his long - standing animosity towards Harry. So, it could lead to a very strange and tense dynamic between them, with Severus trying to balance his new - found protectiveness and his old grudges.
In this scenario, Severus' character experiences a significant transformation. He has to shed his cold exterior to a large extent. He becomes a father figure, which means he has to be there for the boys emotionally. He starts to show emotions more openly, whether it's pride when they do well in their studies or worry when they are in danger. His sense of loyalty also shifts. Before, it was mainly towards certain people or causes, but now his loyalty is first and foremost to Harry and Draco. This new - found loyalty makes him a more rounded and likable character in the fanfiction, as he is no longer just the brooding potions master but a loving and dedicated father.
