Their relationship would shift from a purely platonic friendship to a deeply committed partnership. Harry would become more protective of Hermione, not just as a friend but as the mother of his child. Hermione would see Harry in a new light, as a co - parent and a life - long partner. They would have to communicate on a different level, sharing not only their thoughts about the baby but also their hopes and fears for their future as a family. There would also be some awkward moments as they adjust to this new dynamic, especially in front of their old friends who are used to seeing them as just friends.
The neighbor situation could make their relationship more open. They would have more opportunities to see each other without the hustle and bustle of Hogwarts. This could lead to them sharing more personal stories. For instance, Harry could tell Hermione more about his early years with the Dursleys, and Hermione could share her experiences growing up as a Muggle - born witch. This sharing of personal histories would likely strengthen their bond.
Their relationship would become more intense and committed. Having a baby together means they are now a family unit. They would have to rely on each other more than ever. There would be a deeper level of trust and understanding between them. They would also have to communicate better to make decisions about the baby's upbringing.
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.
If Hermione was Harry's sister, the relationship between her and Harry would be more family - oriented. Ron might initially be a bit jealous as he has to share his two best friends in a different way. But overall, they could form a really strong trio with a new family - like bond.
They would become more reliant on each other. Their relationship would shift from just being friends to co - parents. There would be a deeper level of intimacy and shared responsibility.
The relationship between them can be a journey. Initially, there could be some envy or misunderstanding due to the house differences. Maybe Harry envies the academic resources Hermione has in her house, or Hermione doesn't understand some of the Gryffindor bravado. But as they interact more, they learn to appreciate each other's strengths. Harry might admire Hermione's ability to think outside the box of Gryffindor norms, and Hermione could come to respect Harry's leadership skills that are so characteristic of Gryffindor. This new - found respect and admiration transform their relationship into a more profound and unique friendship.
If Hermione realizes her mistake and tries to make amends, it could lead to a deeper understanding between them. They might have to work through their feelings and have some difficult conversations. For instance, Hermione might have to explain her reasons fully, and Harry would have to decide if he can forgive her.
If Hermione was in Slytherin, their relationship would be more complex. They would have to overcome the typical Gryffindor - Slytherin rivalry. Harry might initially be more suspicious of Hermione's motives since Slytherins are often seen as more self - serving. However, Hermione's intelligence and loyalty would still shine through, and she would prove to Harry that not all Slytherins are bad. Their friendship would likely be more private as they would face scrutiny from both houses.
Their relationship could grow deeper as they share the responsibility of shaping the next generation of wizards. They would have to communicate constantly about the students' progress, and this could lead to a better understanding of each other's thoughts and feelings. For example, Hermione might learn more about Harry's intuition when it comes to students with potential, and Harry could gain more knowledge from Hermione about the importance of academic rigor.
It would deepen on an emotional level. They would have to communicate more about their future and the responsibilities of raising a child. Hermione might rely on Harry more for emotional support during her pregnancy, and Harry would grow to be more nurturing towards Hermione.
