What could happen in a 'Poseidon holds Percy in his lap' fanfic?

There could be a sense of relief. If Percy has been through a tough time, being in Poseidon's lap would mean he's out of danger for the moment. And for Poseidon, there might be pride. He's proud of Percy for his strength and courage, and this moment of holding him is a way to show that. There might also be a touch of sadness, perhaps because Poseidon knows the difficulties Percy will face in the future due to his half - mortal nature.

In a 'Percy meets Poseidon' fanfic, Percy might seek advice from Poseidon. Maybe he's facing a new and powerful enemy in the demigod world, and Poseidon could offer some godly wisdom or a special weapon to help him. For example, Poseidon could give Percy the power to control a new aspect of the sea, like the ability to summon sea monsters that are loyal only to Percy.

Well, perhaps Percy starts seeing things that aren't there. Maybe he gets really paranoid and starts suspecting his friends of things they didn't do.

Well, one possibility is that Percy uses his powers of water manipulation that he got from Poseidon in unexpected ways. He might create water clones to confuse Poseidon during the fight.

Poseidon could arrive to warn Percy about an impending danger in the fanfic. He might bring along some underwater allies to help Percy and his friends at the Camp. It could be a really cool scene where Poseidon shows off his power, like creating a huge tidal wave just outside the Camp boundaries to make a point. And Percy would be both proud and a bit intimidated by his father's presence.

When Percy Jackson meets Poseidon in fanfiction, it could be a very emotional encounter. Percy has always had a complex relationship with his father. They could start by just looking at each other, a moment of silence filled with unspoken words. Then, Poseidon might start by apologizing for not being there for Percy as much as he should have. He could tell Percy about the constraints of being a god and having to abide by certain rules. Percy, on the other hand, could share his experiences at Camp Half - Blood and how he has felt like an outcast at times. This meeting could lead to a new understanding between them, and perhaps Poseidon could offer Percy a chance to become more involved in the world of the gods, which would bring new adventures and challenges for Percy.

Well, it could be about Percy and Poseidon having some sort of adventure together. Maybe they team up to face a new threat in the mythological world. Since it's a fanfic, the author might also explore their relationship in ways not shown in the original stories, like Poseidon teaching Percy some unique powers or skills.

In a Percy Jackson baby sister fanfic, she could have some really cool adventures. Maybe she discovers she has her own unique powers early on, like being able to communicate with sea creatures in a different way than Percy. She could also get into trouble by wandering into the wrong part of the camp, like the restricted areas where the more dangerous magical items are kept.

Well, Percy could start to resent Poseidon and all things related to him. He might decide to leave Camp Half - Blood and try to make it on his own in the mortal world. But then he realizes that his demigod powers still draw trouble, and he has to find a new way to deal with it without relying on his father's name.

One possible plot could be that Poseidon has to keep the female Percy hidden from the other gods because she's a girl and not the expected male hero. He might train her in secret on an isolated island, teaching her about her powers and the history of the gods.
