Let’s face it though. If you don’t think Nico already knows about every other god in the PJO universe, you’re insane. Of course, he knows magicians exist. His dad and Osiris/Julius literally play cards once every week. Persephone’s been showing Anubis her flowers all the time because the Underworld can be hella boring in either place and sometimes Anubis just wants to be surrounded by calm pretty stuff vs graves.
Yeah, he knows about the Norse gods. He accidentally stumbled into one of the realms when he was shadow travelling and still has no idea how he got there. I mean, Nico di Angelo fucking met God in an alleyway after ten cups of coffee and two hours of sleep and he’s only like 5% sure it was a hallucination.
He literally just straight-faced ask Thanatos if other gods existed one time and the man just went “where else would mortals come up with these myths, y’all aren’t that smart” before pushing Nico onto some other deity of the dead so the kid would leave him alone.
Ya boy’s met fucking Kali and thinks she’s awesome and has her damn card. If you ask any god out there about him, chances are they’ve met him or heard of him through conversation with a god who has met him. “Sweet kid,” they’ll say. “Kinda quiet but nice. Real helpful if you need it.”
Nico’s been known all this bullshit. The first time he meets Magnus, he’s not confused or shocked. He just looks him over and then just plainly asks “so how’d you escape?” and literally everyone else in the room is completely shocked he knows, when of course he knows.
He just can’t be bothered to talk about it if it’s not important to anything at stake or doesn’t require his assistance. The world ending’s because some wolf is gonna do something stupid apparently? Great, not his mythology, not his problem. If they need his help, they’ll ask.
what i do is not up to you
