A possible resolution could be that Annabeth finds the courage to tell her father about the abuse. Her father then takes steps to protect her and get her away from the stepmom.
One way is to focus on Annabeth's emotions. Describe how she feels isolated, scared, and confused. For example, show her hiding in her room when her stepmom is around. This can make readers understand the psychological impact of abuse.
Well, it could be about Annabeth learning to deal with this new aspect of her life while still being in the middle of her adventures. Maybe she has to quickly figure out how to manage it in a world full of monsters and quests.
The Weasleys could also be the ones to reach out first. They might realize that Percy was in a difficult situation at the Ministry and that he didn't mean to cause them harm. So they forgive him and they all work together to face whatever threats are out there, like Voldemort's return.
One possible consequence is that Sakura may develop a rebellious streak as a way to cope with the abuse. She might start acting out in school or in other social situations. Another consequence could be that she tries to find solace in substances or other harmful behaviors. For example, she could turn to alcohol or drugs at a young age in an attempt to numb the pain. Or she might engage in self - harm as a way to express the internal turmoil she is experiencing.
She might be overjoyed and immediately reciprocate his feelings. In many fanfictions, their relationship is built on a deep connection, so this could be a natural response.
Perhaps there could be a plot where Annabeth discovers that the abuse has given Percy some hidden powers or a different perspective on his demigod abilities. So she encourages him to explore and master these new aspects of himself. Or, it could be that the news of Percy's abuse spreads among their friends, and they all come together to form a support system for him, which in turn strengthens their group as a whole.
It could also be a matter of self - discovery. Annabeth might have been on a journey to find out who she was outside of her relationship with Percy. Meeting this mortal was a turning point where she realized she wanted to explore a different path, even if it meant leaving Percy. Maybe she thought that being with a mortal would give her a chance to have a more ordinary life, at least for a while.
The most straightforward resolution could be Hinata explaining the truth to Naruto. Once he knows the real situation behind her 'betrayal', he realizes he was wrong to hate her and they reconcile.
She might be disgusted. Gabe is such a horrible person in Percy's life. So Annabeth could show immediate anger towards Gabe just from Percy's description.
Well, one possible reason could be that Percy made a really stupid decision without consulting Annabeth first. Like, if he went off on a dangerous mission on his own when they were supposed to be a team. Annabeth is a very strategic person and she might feel betrayed or extremely frustrated by such actions.
