However, in the end, they still love each other deeply.
One possible challenge could be psychological trauma. Tartarus is a terrifying place, and they might have nightmares or sudden panic attacks. Another challenge could be how they are perceived by others. Some might view them as changed or even dangerous now that they've been to such a dark place.

One popular type of fanfic could be about Percy and Annabeth's journey through Tartarus. It might focus on their struggles, like how they face the various terrifying monsters there. Maybe they use their unique powers and the bond between them to survive. For example, Percy's control over water could be crucial in crossing some of the dangerous rivers in Tartarus, while Annabeth's wisdom helps them make smart decisions when choosing paths in that dark and chaotic place.
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.
He could come back haunted by the terrors he faced in Tartarus. In the fanfiction, Percy might struggle with nightmares and flashbacks. His relationship with Annabeth could be strained as he tries to deal with his trauma alone. But then, through the help of his friends and the love of Annabeth, he slowly starts to heal. Meanwhile, an old enemy from Tartarus could be following him back to the surface world, and Percy has to gather his courage again to fight it off and protect his loved ones.
One possible fanfiction could be about Percy and Annabeth's struggle in Tartarus, where the darkness of that place starts to seep into their minds.

They face all kinds of terrifying monsters and challenges that test not only their physical strength but also their mental stability.
In some fanfictions, Annabeth and Percy might struggle with PTSD. They could have nightmares about their time in Tartarus. Percy might be overly protective of Annabeth, and they may need time to heal their emotional wounds together.
In some fanfictions, Percy uses his sense of humor as a coping mechanism. He might make light - hearted jokes about the Tartarus situations in the nightmare to Annabeth when they wake up. Annabeth, on the other hand, might try to analyze the nightmares. She'd break down the elements and figure out what in their subconscious is causing these dreams.
One interesting scenario could be Percy and Annabeth finding a hidden, powerful weapon in Tartarus that gives them an edge against the monsters there. Maybe it's a sword that can cut through the very fabric of Tartarus's darkness.
Percy might develop more of a steely determination. In Tartarus, he has to face extreme danger, which could make him even more resolute in protecting Annabeth and getting out. Annabeth, on the other hand, could become more resourceful. She'd have to use her wits in this strange and deadly place.
