How would the relationship between Harry and Hermione change in a 'Harry and Hermione married fanfic' compared to their friendship in the original series?

Well, they'd be closer in a more family - like way. In the original, they're good friends, but if raised together, they'd have that sibling - like bond. They'd probably be more protective of each other right from the start. For instance, Harry might not be as hesitant to ask Hermione for help as he sometimes was in the books, and Hermione would be more likely to mother - hen Harry.

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.

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.

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.

In the original series, their relationship was mainly defined by the house divide and their different loyalties. However, as demigods, a whole new dimension is added. They would have to put aside their old grudges because they are now part of a different world with different rules. Their relationship could become a friendship built on mutual survival and the understanding of their demigod natures. They may even find that their differences as a Slytherin and a Gryffindor are assets when dealing with the various tasks and threats that come with being demigods. Their bond could grow as they explore their new powers and face challenges that only they, as demigods, can understand.

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.

Their relationship could become deeper. Meeting Hermione's relatives would mean Harry is getting more involved in her personal life, which might make them closer. They would share more experiences related to her family, and this could lead to more understanding and trust between them.

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.

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.
