In the fanfiction, perhaps Thalia becomes really shy and tongue - tied whenever Percy is near. She tries to hide her feelings but her actions, like blushing or stammering, give her away. For example, when Percy asks her a simple question, she might start to fumble for words and her cheeks turn red. And she might get a bit jealous when she sees Percy interacting closely with other girls.
Well, it could be that Thalia's crush on Percy starts to influence her decisions in the story. She might be more willing to take risks to protect Percy, even if it means going against her own better judgment. Maybe there's a battle and she jumps in front of Percy to shield him from an attack without thinking twice because her feelings for him are so strong. And she might start to notice all the little things about Percy, like the way he smiles or how his hair is always a bit messy, and these small details just make her crush grow deeper.
One possible scenario could be that Thalia is constantly trying to find excuses to be around Percy. She might volunteer for quests or tasks that she knows Percy will be involved in just so she can spend time with him.
One possible plot development is that Thalia tries to hide her crush from everyone, including Percy. She's afraid of being rejected or making things awkward in their group. So she keeps her feelings bottled up, but her actions sometimes give her away, like she's always the first to volunteer to help Percy when he's in a tight spot.
Another scenario could be during an adventure. He shows great leadership and courage, saving his companions from danger time and time again. His comrades, both male and female, start to see him in a new light and develop feelings for him. It's also possible that in some fanfictions, Percy is in a different world or time period, and his out - of - place but amazing abilities make him the center of attention and attraction.
One scenario could be that Percy has had a really tough battle and is feeling down about his performance. Thalia finds him sitting alone, and she sits beside him, tells him that everyone has off days and that his strength is more than just his combat skills. She might share some of her own insecurities and how she overcame them, making Percy feel less alone.
Well, perhaps they are on a quest together. As they face various challenges and rely on each other more and more, their bond deepens. Then, when they reach a beautiful, secluded place during their journey, like a hidden glen or a mountaintop, they kiss. Or it could be that they have a misunderstanding at first, but after clearing things up, the kiss is a sign of their newfound understanding and love.
Perhaps in the fanfiction, Percy is forced into a situation where he has to choose between Thalia's life and the safety of many others. If the situation is presented in such a way that killing Thalia seems like the only option to save a large number of people, he might be pushed to do it. It could also be related to some prophecy that Percy misinterprets. If the prophecy seems to suggest that Thalia will bring great doom, and Percy takes it too literally, he could end up trying to kill her.
One possible plot could be that Jason is really shy about his crush at first. He tries to be around Percy more often, like joining the same quests or training sessions. He might secretly do nice things for Percy, like leaving his favorite food at his cabin without saying who it's from.
Perhaps in the fanfiction, there are other characters who are jealous of Annabeth's intelligence or skills. So they start spreading rumors or making unfair remarks. Percy defends her because he knows her true worth and capabilities. He would stand up and say things like 'You don't know her like I do. She's always been there for all of us.'
They could be like siblings. Percy and Thalia might act as the older siblings, protecting and guiding Nico. Percy, with his leadership skills, and Thalia, with her combat abilities, would be great at looking out for the younger Nico. They could also be like cousins, with a close - knit bond but still having their own individual family heritages that sometimes create interesting dynamics.
One possible scenario is that Naruto accidentally bumps into Yugao during a festival in the village. He's immediately smitten and starts following her around, trying to find excuses to talk to her. Another could be that Yugao is assigned to train Naruto for a special mission. Naruto, during the training, develops a crush on her because of her cool and skilled fighting style.
In such a fanfiction, Jason might be jealous because Percy has a strong connection with the sea and Thalia is a powerful daughter of Zeus. Maybe Jason feels overshadowed. For example, Percy's feats in the ocean make him stand out, and Thalia's leadership skills are remarkable. Jason could be jealous of the attention they get.
