Imagine if Maria agreed to hide the kids out w/ Hades though. They managed to actually get there safely and Hades being Hades and how much he was just obsessed with Maria and her kids he would make it so as long as they were there, they didn’t age. He tries making it as homey and “lively” as possible to because he knows Maria is still kinda against this but doesn’t want her kids hurt obviously.
So imagine demi gods and others just being terrified that they have to walk through the underworld and just all of sudden seeing these two random kids playing hopscotch in a random patch of park type area next to a lake of fire completely unfazed. Or better yet, Bianca and Nico are the type to go ahead and make a game out of creeping people out as much as possible. So throughout the entire visit, they just follow the demigods completely silent in like masks or something saying nothing.
Or being completely intimidated by Hades and just mid rant Nico and Bianca come running in. Pulling on his robes like:
Bianca: “Dad! Dad, can we have the cake that’s on the counter!”
Hades: “Oh my Gods–Go ask your mother!”
Nico: “She said to ask you.”
Hades: “UuuuUUUGH, well did you eat dinner yet?”
Hades: “Did you eat your vegetables?”
Hades: “….Go, but if she asks I said no.”
