They could reveal secrets about the gods. For instance, they might tell Sally about some of the gods' more human - like qualities or their petty squabbles that are not widely known. Maybe they share a story about how Zeus and Poseidon were arguing over something trivial, like who had the better view from their respective thrones on Olympus.
Another secret could be about the real identities of some of the other demigods at Camp Half - Blood. They might tell Sally that a certain demigod who seems really ordinary on the surface actually has a very powerful and dangerous parentage that they've been keeping under wraps to protect the camp and the demigod in question.
Maybe Percy tells Sally about Annabeth's amazing adventures in the fanfiction. For example, her heroic deeds in battles against monsters.
Percy could also reveal Gabe's possible illegal activities. Maybe Gabe is involved in some small - time theft or is in cahoots with some shady characters. Percy would share this with Annabeth as he trusts her and knows she can handle such information.
One possibility is that they tell Sally about their latest adventure in the demigod world. Maybe they share details about a new monster they defeated or a mysterious place they discovered. For example, they could be telling her about a hidden temple filled with ancient magic that they had to navigate through to retrieve an important artifact for Camp Half - Blood.
Well, it could be because Sally is an important person in Percy's life. He trusts her and wants to share the interesting things about Annabeth from the fanfiction with her.
Sally would likely become a mother figure to Annabeth. She would offer her advice and support, just as she does for Percy. Percy and Annabeth's relationship would become more domestic. They'd have more time to just be together, sharing small moments like having breakfast together in the morning. Their bond would strengthen as they face the normal day - to - day challenges of living together, along with Sally.
She might tell Piper about Percy's heroic deeds in fanfiction. For example, how he faces powerful monsters and overcomes seemingly impossible challenges, just like in the original stories but with new twists in the fan - created scenarios.
One challenge could be office gossip. People might start talking if they notice Percy and Annabeth getting too close. This could create a difficult work environment for both of them. Another challenge is the power dynamic. Percy has to be careful not to abuse his power as a boss when it comes to his relationship with Annabeth.
Maybe in the fanfiction, Annabeth moves in to further study some ancient texts that Sally has access to. Percy is excited as he gets to spend more time with Annabeth. They face challenges like adjusting to living together, like who takes out the trash or does the dishes. But overall, they create a warm and loving environment, with Sally acting as a guiding figure for both of them.
In this fanfiction, Naruto might reveal his insecurities about being the Jinchuriki at first. He could share how he was really scared of the Nine - Tails inside him and how he had to constantly battle with the fear of losing control.
It could be Chiron, the centaur. He's always keeping an eye on the campers and would likely be concerned if he caught them up to something. He might give them a stern talking - to and some extra chores as punishment.
