i love that canon nico's appearance is described as unnerving. percy says he has a glint in his eyes that makes you think he's either a genius or a madman. people comment about how his presence is eerie and how he just seems to show up, like a specter. his smile is said to be more unsettling than his scowl. pretty privilege nico is a fun hc but i just love the idea that he looks like some eldritch being at his worst and a sopping run-over black cat at his best.
