Summary
When your dad, who is also a god, and also king of the world's oceans, invites you to a party full of important dignitaries and also his actual family, you can't really refuse the invitation. Percy wishes that he could though. Now he's stuck on a quest, again, with his father's actually legitimate godly children. Limited budget, limited time, limited idea of what he's walking into. Why did he let himself be talked into this?
Triton has feelings surrounding his father's bastard child. Those feelings are mostly made up of anger. There's also a healthy dose of rage and betrayal mixed in, for flavor, but it's mostly anger. And with his powers weakening, Triton is also reliant on the demigod to guide him through the quest they have all been assigned. Once this is over, Triton will be taking the nap of his lifetime.
Rhode is confused by the demigod child. Percy himself is a massive contradiction. Born of two worlds, in so many different ways, and not belonging truly to any of them. She hopes that something of this will help him. But little brothers have a trend of not doing what's best for them.
Through this all, there is a brewing conspiracy, a prophecy, and a primordial goddess trying to claim what's hers.

Summary
PLEASE READ MERCY UPON OURSELVES BY HEDGEHOGY BEFORE YOU READ THIS!!!!!
Trigger warnings: ⚠️ Mentions of child abuse, suicidal thoughts, self harm, major character injury, neglect, eating disorders, and depersonalization. Separate warnings will be in each chapter notes.
Poseidon didn’t know he had another son. And now he’s saddled with not one but two teenagers that have lost their mothers, as he tries to wrangle his grief for his wife into submission. It’s not easy.
-
Triton didn’t want another brother. He was perfectly content with being an only child, and having a brother was, quite honestly, one of the last things he would think about after Mama died. Of course he disliked the little shitface! Trust him, that wouldn’t change.
-
Percy is hurting. His mom is dead, and he’s living with two strange men in a strange house when all he wants to do is curl up, go to sleep, and never wake up.

Or or: Tritons traumatized and can’t deal with it

Summary
Having to deal with the consequences of a goddesses actions against a child of the sea. Had been bad the first time for all of them. And Triton hadn't wished it on anyone else.
To have it happen almost a second time through one of her children. Was proving to be just as painful as the first.
Even if this time it was his half brother instead of his child.
Or
When the consequences from the Capture the Flag game are more severe because Percy does nearly die against the Ares cabin. It brings back some bad memories for his Dad's side of the family due to Annabeth's involvement. And as a result ends up gaining a very (in Percy's opinion.) overprotective immortal family in the process.

Summary
Odysseus sighed heavily as his raft floated closer to Ithaca. He was so close. He had gone through Hell to get here, and he wasn’t going to let anything take him away from it.
His raft rocked a little, and Odysseus picked up his knife in a flash. Was it a creature? Just water? He wasn’t going to take any chances.
Then a head poked out of the water a few feet away from the raft.
Or,
An under appreciated god chats with Odysseus about morals and death.

Him making a jab about his brother's swordmanship skills was supposed to be taunt about him and whoever had been teaching him. Nothing more.

Summary
He had always tried to be the best version of himself and not disappoint Poseidon. But now that he knew Percy was his favorite son, it felt like a slap in the face.
Triton knows he shouldn't feel this way. After all, Percy is only human and still young while he's a god and future heir of Poseidon. He should be above such feelings, it was unnatural for them. But he can't help but feel like he had to do better, to prove to his Father that he wasn’t replaceable.

Summary
Maybe sending a child after another person who is displaying unhinged behavior and took him out to the woods to kill him the last time they saw each other. Is not the smartest idea Hermes.
OR
Percy appreciates the concern from the sea side of his Dad's family after the fight with Luke on the Andromeda. Really he does. But as nice it is to have someone else besides his mother fussing over him. He also would just like some rest that isn't supposed to be doing camp activities.
