Nico di Angelo as a brother (to Hazel)
-Nico learning all the gen z slangs so that he can teach Hazel
-Taking Hazel to the mall, buying her all the clothes that are trending
-Tells her how computers and smartphones work
-All just so that she doesn't feel left out from the present world, unlike him
-Nico half joking to ghostify Frank if he ever hurts Hazel
-(Not Frank turning into a squirrel bc he got scared)
-Shadow traveling her to Sammy Valdez's grave so that she could say a proper goodbye
-Kissing her forehead regularly, even when he doesn't like physical contact that much
-Volunteering to be her model when she wants to draw something
-Being so happy that he grins when he hears that she became a praetor (and happily insisting that he give her Jules Albert as a present-lol)
-Always making sure to visit her at least once a week
-Him doing all of these because he wants to be there for her when Bianca wasn't able to be there for him
I just feel like Nico would be the bestest brother to his siblings. Him and Hazel's relationship would be GOLD (pun intended lolll)
