I'm not sure specifically as it could be one of many fan - made stories. It might be a story where Nico, a character, does something to save Percy in the context of fanfiction. Fanfiction often takes existing characters and creates new, unique scenarios for them.
Well, first of all, AO3 is a great place to look. It has a very user - friendly search function. Just type in 'nico saves percy' in the search bar, and it will show you relevant stories if they exist. Another option is to check out some Percy Jackson - focused fan communities. Sometimes, fans share their works directly in these communities, or they can point you in the right direction to find the specific fanfiction you're looking for. Additionally, some Tumblr blogs dedicated to Percy Jackson fan works might also have links or mentions of such a fanfiction.
In the fanfiction, Percy might use his demigod senses. Since he has been in the casino before, he knows the layout and the tricks it plays. He could be searching for any signs of Nico's presence, like his unique demigod aura or any items that Nico might have left behind as he moved through the casino.
The camp leaders might betray them. If there is a power struggle within the camp, and Percy and Nico are seen as threats to the current leadership's power, the leaders could set them up. They could make it look like Percy and Nico are breaking camp rules or endangering the other campers, which would lead to the rest of the camp turning against them.
I don't know for sure as I haven't read this particular fanfiction, but usually in fanfiction, Percy could be a character from a popular book, movie or TV series.
Yes, there are many. You can look for ones on platforms like FanFiction.net. Just search for 'Percy and Nico friendship' and you'll find a lot of great stories that focus on their bond as friends, like adventures they might go on together or how they support each other in the face of challenges.
One great fanfiction could be about their adventure in an unknown magical realm. They might have to combine their unique powers - Jason's control over the winds, Nico's ability to summon the dead, and Percy's power over water to defeat a powerful dark force.
It could be because of the potential for a romantic relationship in fanfiction. Some fans like to explore the idea of Nico having romantic feelings for Percy. In that case, possessiveness might be a natural part of showing his intense emotions. He wants Percy all to himself, not sharing him with others, especially when there are other characters who might also be interested in Percy.
One possible fanfiction could be 'The Unseen Pain'. In this story, Percy might be crying due to the overwhelming pressure of his demigod duties. Nico stumbles upon him in a secluded corner of Camp Half - Blood. Nico, initially hesitant, decides to approach Percy and offer his silent support.
One of the common themes in fanfictions involving Percy, Nico, Jason and Chaos could be their epic adventures. For example, they might team up to face a new and powerful threat that emerges from the chaos itself. Maybe they have to journey through different realms, using their unique powers and personalities to overcome obstacles.
