One possible plot could involve a prophecy. In this fanfic, the pregnancy might be part of a greater prophecy that they are meant to fulfill. Thalia and Nico then have to figure out how to protect the unborn child while also dealing with the various forces that are either trying to help or harm them because of the prophecy. They may have to seek help from old friends and allies to ensure the safety of the pregnancy.
Well, it could be a story where they are in a very unexpected situation. Maybe they were on some sort of magical adventure together and something happened that led to Thalia getting pregnant. Nico, being the father, might be initially in shock but then steps up to support Thalia. They could face a lot of challenges from their friends and the world around them as this is a very unorthodox situation in their universe.
Perhaps it could be a story of love and acceptance. Thalia and Nico fall deeply in love, and the pregnancy is a result of that. However, they belong to different groups or have different responsibilities. Their friends and families might not be accepting at first. But through their journey, they show that their love can overcome all these obstacles and that they are ready to take on the new role of parents, no matter how difficult it may be.
Well, aside from Thalia and Nico, there could also be other characters that play important roles. For example, their friends like Percy Jackson or Annabeth Chase might be involved. They could either support Thalia and Nico during this time or have some sort of conflict with them due to the unplanned pregnancy. Their reactions could add more depth to the story.
Perhaps it's a fanfiction focused on their relationships. They might form an unexpected bond in the story. Nico, who has often been a bit of an outcast, could find real friendship and acceptance from Percy and Thalia. They could start out on a simple quest, like finding a lost artifact, and during this journey, they learn more about each other and grow closer as friends.
Well, one possibility could be that they are given special status on Olympus. Maybe they are tasked with keeping the peace among the gods, which would lead to a lot of interesting interactions with the deities. They might also use their unique powers to improve the living conditions on Olympus, like Percy controlling water to create beautiful fountains or something.
It could be that they run away to find someone. Maybe a missing demigod friend or a powerful being who can help them with a problem they're facing. Percy, Thalia, and Nico might have received a mysterious message or a vision that leads them on this journey. As they run away and start their search, they encounter various obstacles. They have to cross dangerous terrains, deal with unfriendly gods or demigods who don't want them to succeed, and also figure out how to work together effectively. Their friendship is tested, but in the end, they grow stronger together.
One common theme is friendship. Since they are both from the demigod world, their friendship is often explored in different ways, like how they support each other in battles. For example, in many fanfics, Nico uses his powers to help Thalia when she's in a tough fight against some mythical creatures.
Perhaps it starts as a misunderstanding. Percy might misinterpret something Nico does as a threat to his friends. Thalia, being Percy's friend, jumps in to defend him. Nico, feeling attacked unjustly, then retaliates. It could turn into a full - on fight with them using their powers. Percy with his water - based powers, Thalia with her lightning, and Nico with his control over the dead. The fight could be a very intense and action - packed scene in the fanfic.
One possible plot could be that they face a lot of challenges. Maybe they are in a world full of danger and they have to protect their unborn child. They might need to find a safe place to stay, away from their enemies. Thalia could be using her skills to keep them safe while Luke tries to figure out how to provide for their future family.
Perhaps in the fanfiction, they are in a relationship and planned the pregnancy. The story could then focus on how they navigate the changes in their relationship. Reyna might be worried about still being a strong leader while pregnant, and Nico could be concerned about protecting his new family from the dangers of their world. They would also have to face any prejudices or challenges within their community regarding their situation.
A fanfic that stands out is 'The Trio's Trials'. This one is interesting because it not only focuses on their physical adventures but also their emotional growth. We see Percy dealing with his leadership role, Thalia coming to terms with her past, and Nico learning to open up more. The character development throughout the story is quite engaging.
This is a very unorthodox and non - canon idea. However, if such a fanfic were to exist, perhaps the plot could involve Percy and Thalia having to deal with the shock and the sudden change in their lives. They might face judgment from their friends and the demigod community. But this goes against the established relationships in the original works.
