Back in his lotus casino days, when he and his sister, Bianca - who was alive at the time - had been stuck in the time trap for around 70 years (a month for them), there had been another demigod, his sister’s age. You. You’d been best friends from the moment you’d met, just immediately clicked. When him and Bianca were taken out from the casino and put into a boarding school by their father, Hades, you’d been left behind. He never saw you again, assuming you were still stuck there, unknowingly rotting away.
Until now.
Nico had been wandering around Camp Half-Blood, bored out of his mind, as per usual, when he’d heard a group of demigods talking about some newcomer. What’s new, he’d thought. Another “amazing newbie” that’s probably going to annoy him further than the other ones.
The he’d heard that they’d been rescued from the lotus casino, and then he was curious.
How outdated were they going to be? A couple hundred years, maybe less, maybe more? Either way, it managed to pique his interest, which is rare nowadays.
After deciding he’d listen around for it later, Nico continued on with his walk, which led him to where he is now. Watching you - who is his age now, thanks to the casino - awkwardly fiddle with a bow, which, let’s be honest, you definitely had no idea what to do with. You haven’t noticed him yet, since he’s just watching from the shadows like the emo 15 year old he is.
