They could become even closer friends. After going through the war together, they have a deep bond. Maybe they start to rely on each other more than ever, sharing every little detail of their lives.
There's a possibility that their relationship could turn romantic. With Ron out of the picture (assuming in this fanfic's context), they might start to see each other in a new light. They've always had a strong connection, and the post - war peace could make them realize their feelings for each other. They could start dating, going on magical dates around the wizarding world.
Their relationship might start with them being comrades in arms. After the war, they would have more time to really talk and understand each other on a deeper level. This would lead to romantic feelings.
In many of these fanfictions, their relationship often becomes more intense and reliant. For example, in stories where they are facing the mystery of Riddle together, they learn to trust each other even more deeply. They might start to rely on each other's unique skills, like Harry's courage and Hermione's intelligence, in a more profound way.
Hermione, on the other hand, could become more confident in her leadership skills. In the post - war fanfic, she may take on more responsibilities in the wizarding community. With Harry by her side, she realizes that she can make a real difference. Her character grows from being the brains behind Harry's operations to a leader in her own right. She also becomes more open - minded about different ways of magic, as she and Harry explore new areas of the wizarding world together.
The relationship could also develop through a series of misunderstandings and reconciliations. They might misinterpret each other's actions at first, leading to some tension. But as they clear up these misunderstandings on the train rides, they grow closer. Eventually, all the pent - up emotions lead to that kiss on the train as a way of finally expressing their true feelings.
At first, it might start with simple moments of realization. Harry begins to notice how Hermione's presence makes him feel more at ease in different situations. As the story progresses, they might have deeper conversations that lead to a stronger emotional connection.
At first, it would be really rocky. Harry has a history of distrusting Snape, and Hermione might be a bit cautious too. But as time passes, Snape's care for them in his own strict way would start to show. He'd probably be tough on them about their studies, but they'd see it's because he wants them to succeed.
It would likely cause a great deal of strain. Harry would probably feel betrayed and angry at Hermione. Their friendship, which was once strong, would be severely damaged.
As Hermione comforts Harry, they start to develop a more intimate bond. Harry begins to understand Hermione's caring nature on a deeper level. He realizes that she is always there for him, no matter what. This makes him more protective of her as well. For example, in a dangerous situation, he might be more concerned about her safety because of the special connection they've developed during these comforting moments.
It might also just be a normal part of their relationship. If the fanfic is set in a world where they are very comfortable with each other, it could just be a casual display of their closeness without any major relationship shift, but still showing how important they are to each other.
Harry's personality can grow in terms of his emotional intelligence. Since Hermione is so perceptive, he learns from her how to better understand his own emotions and those of others. He becomes more empathetic. Hermione, in a marriage with Harry, might develop a stronger sense of adventure. She realizes that there's more to life than just books and research. They both influence each other in positive ways, making their personalities more well - rounded and adaptable to the challenges of married life.
