They might face new and strange monsters. For example, they could encounter a sea - serpent that has the power to control the weather around the Argo 2. Percy would use his water - controlling abilities to try and fend it off while Annabeth comes up with a strategic plan to defeat it.
The main characters are clearly Percy and Annabeth. Percy, the son of Poseidon, is known for his courage and his ability to control water. Annabeth, the daughter of Athena, is highly intelligent and strategic.
Well, it could be about Percy and Annabeth having some sweet, romantic moments on the Argo 2. Maybe they're sharing secrets, or just enjoying the journey together while facing some minor challenges on the ship.
In fanfiction, their relationship might evolve in a more spiritual way. As they travel on the Argo 2, they could visit places that are significant to the gods. These experiences could make them understand each other on a deeper level. For example, they might visit a temple dedicated to Athena, and Annabeth could share her deepest feelings about her mother with Percy, and Percy would be more understanding of her connection to her divine heritage.
One possible implication could be a change in the group dynamics. The other characters on the Argo 2 would likely have to adjust to the situation. They might become more protective of Annabeth and start thinking about the future in a different way, like planning for the baby's safety in their dangerous adventures.
The story could progress with the group taking on a more defensive stance. They might avoid battles that are too risky to protect Annabeth and the unborn child.
In a large number of Percy and Annabeth fanfictions, they are indeed presented as soulmates. Their shared adventures, the way they understand each other without many words, and the deep loyalty they have for one another all contribute to this perception. Fanfiction authors often build on their existing relationship from the original works and enhance it to the level of soulmates. They might show it through things like Percy being able to sense Annabeth's distress from afar, or Annabeth always knowing exactly what Percy needs in difficult situations. This soulmate - like relationship makes for very engaging and heart - warming stories in the fanfiction realm.
Jason is likely to be another main character. Since he has his own set of skills and knowledge, he might have an interesting relationship with Percy in this story. Maybe he's a bit jealous at first of Percy's control over the ship, but then they end up working together really well. And of course, Piper could be there too. She might use her charm - speak abilities to help the crew communicate with any strange creatures they encounter during Percy's time controlling the Argo 2.
It could be that Annabeth has a misunderstanding about Percy. She might think he's a threat to her position or status at the camp, so she bullies him to try and keep him in check.
