Being a half blood Percy thought he could easily blend in, after all he was half mortal, so that meant a part of him actually belonged there, but of course it's Percy we're talking about. So, no, being a halfblood in New York wasn't easy. And on top of everything he was a teenager for gods sake, a teenager, it's hard enough already being a child of the gods and on top of it all school, high school. Percy simply didn't know what to make of his life, who to live for, after all his mom was dead, Sally was dead, he had failed to save her; he left her with Hades, and Hades being as heartless as he was, being as mad and angry as he was at Sally for giving birth to Percy, a child of the sea god (whom was forbidden of even existing, thank you very much). Poseidon broke their oath and Sally had to suffer, that didn't seem fair to Percy, Poseidon broke the oath why in a fair world would Sally have to suffer the concecuences for an oath that wasn't even hers to keep, but of cource Hades couldn't bring all his anger and dissapointment down on Poseidon for wouldn't dare confront Poseidon because as much as he denied it he knew the truth was and still is that Poseidon is stronger, and has more power than Hades, he would have to me insane to even think or plot anything against the sea god. So who was left? No one, Percy had a deep resentment and anger all directed towards Poseidon and he was practically the only family he had left eventhough he often liked to deny he was even somehhow related to Poseidon.
