In this fanfiction, a possible plot development could be that Thalia's protection of Percy reveals a long - forgotten prophecy. As she guards him from various attacks, they start to notice strange signs and omens. These signs might be related to a prophecy that could change the fate of all demigods. Thalia then has to not only protect Percy from immediate danger but also figure out how to deal with the implications of this new - found prophecy. Along the way, their relationship could grow stronger as they face these challenges together.
Well, perhaps in the fanfiction, Thalia protecting Percy causes a rift between different camps of demigods. Some might see Percy as too important and Thalia's protection as a sign of favoritism. This could lead to internal conflicts among the demigods while they also have to face external threats. And as Thalia is so focused on Percy, she might have to make some tough choices between her loyalty to her friends in the other camps and her duty to protect Percy.
One interesting plot development could be that Thalia's protection of Percy leads to her uncovering a new threat against the demigods. Maybe she discovers a hidden group of monsters that are specifically targeting Percy because of his unique powers. This could then lead to an epic battle where Thalia uses her skills as a daughter of Zeus to fend off the monsters and keep Percy safe.
Well, Thalia might initially be shocked when she discovers what Gabe is like. She could then start to investigate more about Gabe's background and motives. Maybe she finds out that he has some sort of connection to a minor god or goddess who is using him to cause trouble for Percy. This discovery could lead to a whole new adventure where Thalia has to deal with this god or goddess while also trying to protect Percy and his mom from Gabe.
Perhaps a fanfiction where Percy and Thalia are transported to an alternate dimension. In this new world, they have to figure out how to get back while also dealing with different versions of their friends and enemies. Thalia might have to face an alternate version of herself who has turned evil, and Percy could be the one to help her see the light again. It would be full of action, drama, and self - discovery.
A great scene is when Percy is facing a moral dilemma. Thalia steps in to comfort him. She listens to his concerns without judgment and then offers her own perspective. For example, if Percy is not sure whether to trust a new demigod or not, Thalia shares her own experiences of making friends and enemies among the demigod community. She helps Percy see the situation more clearly and makes him feel better about whatever decision he will make. And sometimes, when Percy is just homesick, Thalia will create a little makeshift 'home' environment for them, like making a campfire and sharing stories, to make him feel a bit more at ease.
One idea could be that in the alternate universe (au), Thalia never becomes a tree. Instead, she and Percy go on a quest together to find a powerful artifact that can stop an ancient evil from awakening. They face many challenges along the way, like battling mythical creatures that are stronger than usual due to the dark magic seeping into the world.
Perhaps the prophecy involves Thalia having to team up with an unexpected ally. For example, a former enemy who has also been touched by the prophecy in some way. They would have to overcome their differences and learn to trust each other while facing numerous challenges like dangerous quests and battles against powerful Titans or other mythical foes.
One idea could be that Percy and Thalia have to go on a secret quest together, away from the rest of the demigods. During the quest, they discover new powers within themselves and also realize their feelings for each other are deeper than just friendship. Another could be a story where they are trapped in a magical realm and have to rely on each other's skills to escape, with lots of action and some tender moments in between.
A really engaging storyline could be them being transported to a different era in the world of Greek mythology. They would have to adapt to the different rules and powers that exist in that time while still relying on their own abilities. This would put their friendship and skills to the test in a whole new and exciting way.
One idea could be exploring how their demigod powers are affected during the pregnancy. For example, Percy's control over water might become more erratic due to hormonal changes. Another could be the reactions of their friends and the demigod community. Some might be supportive, while others might fear for the future of the half - bloods. Also, they could face challenges from the gods, as the birth of a new demigod with such powerful parents could shift the power balance in the mythological world.
Some fanfictions might focus on the relationship between the three of them. It could be a story where Percy, Luke, and Thalia are stranded in a strange place. They have to rely on each other to survive. During this time, they start to understand each other better. Percy learns more about Luke's past that made him turn bad in the first place, and Thalia tries to be the mediator between them, leading to a more complex and interesting dynamic.
One possible plot could be that Percy accidentally possesses Thalia due to a magical mishap. He then has to deal with her powers and her relationships while in her body. Maybe he has to keep it a secret from their friends at first.
