The new relationship in this fanfiction would completely transform their interactions. Imagine Percy now having to deal with Annabeth's teenage angst or her dreams for the future in a fatherly way. He'd be more involved in her personal growth. Annabeth, in turn, would have to come to terms with Percy having a say in her life in a way he didn't before. Their relationship would no longer be just about fighting monsters together. There would be family - related emotions, like Percy feeling pride in Annabeth's achievements in a different, more paternal sense, and Annabeth might feel a new sense of security or annoyance depending on how Percy exercises his 'fatherly' rights.
Their relationship would likely become even deeper. They would be partners not only in their heroic adventures but also in parenting. They would have to support each other in raising their child, like Annabeth helping Percy understand their child's academic needs while Percy might be better at teaching combat skills. They would also have to make decisions together about their child's future, whether it's about staying at Camp Half - Blood or trying to live a more normal life in the mortal world.
Well, it completely shatters their trust. Percy would be devastated and feel extremely betrayed. He would question all their past interactions and wonder if Annabeth ever really cared about him.
When Annabeth is mad, Percy will likely try to make it up to her. He might start doing all kinds of things like bringing her favorite foods, trying to help her with her projects. But Annabeth might not be so easily swayed. She'll be looking for a real apology and for Percy to show that he's learned his lesson. So the relationship becomes a bit of a power struggle, with Percy trying to regain her favor and Annabeth deciding whether he's worthy of it.
Their relationship would likely become more nurturing. They would have to rely on each other more as they take on the role of parents. For example, when the child has a nightmare about monsters, Percy might be the one to comfort the child first while Annabeth figures out how to better protect the home. Then they would discuss their concerns and fears for the child together, strengthening their bond as they face these new challenges as a couple.
Well, they would probably communicate better. In Tartarus, they had to rely on clear communication to survive. So, back in the normal world, this would carry over. They'd be more open about their feelings, fears, and plans, which would strengthen their relationship in a more emotional way.
They might become more protective. Since they are dreaming of having a daughter, they would start to think about all the potential dangers she could face. Their relationship could grow deeper as they bond over their shared hopes and fears for their future child.
At first, it might become strained. Annabeth could be hurt and pull away from Percy. She might not want to be around him as much.
The relationship will likely grow stronger. They'll have to rely on each other more for daily tasks and support. For example, if Percy has a bad day at work or school, Annabeth will be there to comfort him right away, and vice versa. However, it could also be a bit strained at times. There might be moments when they feel suffocated by each other's presence, but they'll have to work through those feelings to keep their relationship healthy.
Their relationship could become more intense. With her hearing his thoughts, they'd be more in tune with each other's feelings. It might make their bond stronger as they'd understand each other on a deeper level.
Their relationship might develop through more in - depth conversations. Since they are engaged, they start talking about their future, like where they want to live. Maybe Percy wants to live near the ocean and Annabeth has other ideas, and they have to compromise.
