Jewlz Maybe Percy is just a childhood hero to Nico. Plus, you don't have to go all crazy and saying that it ruined your childhood.
Bethany I really don't know why it bothers you so much, one of my friends still have a crush on Nico even after they found out he was gay/something else and has or still has a crush on Percy. I find it wrong that it ruins your one child hood!
This answer contains spoilers… (view spoiler)[Well, we don't know for certain that he's gay (he could be bisexual or another sexual orientation), but he's definitely not straight; he had a crush on Percy (and maybe still does). And how would that ruin one's childhood? It didn't ruin mine. (hide spoiler)]
