Well, their relationship would change quite a bit. Firstly, they would have a stronger sense of trust as they share this special ability. In their Animagus forms, they could be more vulnerable with each other. For instance, if Harry becomes a dog, he might show his loyalty to Hermione in a more instinctive way. Hermione, if she becomes a raven, could bring Harry interesting things she finds while flying. They would also have a lot more shared experiences in their animal forms. They could go on secret adventures together, which would bring them closer. And this closeness might make their relationship more than just a friendship, especially as they rely on each other in their new forms for different things like protection, exploration, and communication.
In fanfiction, if Harry and Hermione become Animagus, they could have many new adventures. For example, they might use their animal forms to spy on the Death Eaters without being detected. Harry could become a stag, like his Patronus, which would give him speed and grace in the forest. Hermione might become an owl, as owls are associated with wisdom and knowledge, just like her. They could communicate secretly in their animal forms, adding an exciting new layer to their relationship and their fight against evil.
Their relationship might become more formal in public settings as they now hold a lordly and ladylike status. They would have to be more aware of their image. But in private, they could still be the same old friends, just with a deeper bond due to the shared responsibilities.
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.
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 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.
The Avengers would also become more diverse in terms of their capabilities. Harry's magic - based Animagus abilities would introduce an element of the supernatural to the team. This could attract new threats or allies. For instance, some magical creatures might be more likely to interact with the Avengers because of Harry's presence. It would also change how the public views the Avengers, as they now have a member with such extraordinary and otherworldly abilities.
Their relationship could change their roles quite a bit. As a couple, they might be more involved in diplomatic relations within the wizarding world. Harry is already a hero, and Hermione is highly respected for her brains. Together, they could bridge gaps between different wizarding communities. They might also be more involved in the Ministry of Magic's decision - making processes, using their influence to promote more progressive magic - related policies.
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 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.
In other stories, their Animagus forms can be a source of conflict at first. For example, if one is better at controlling their form than the other. But eventually, they learn from each other. Harry might be more instinct - driven in his stag form, while Hermione's otter form makes her more inquisitive. This contrast helps them grow both as individuals and as friends in the fanfiction world.
