Seriously. Do y’all not remember Hazel cursing Octavian out after she brought Percy to him? Or all the other instances she cursed...
It's funny how fanon and canon versions of Nico and Hazel are completely reversed because like Hazel is cannonically very bold and sort of like a rebel almost? She also curses and stuff (unlike the fanon "omg hazel faints if she hears someone curse" version) and whereas Nico is rather polite and not at all rude and mean as some people interpret him, interesting how their personalities are reversed in fanon interpretations
