Practically the gist of Apogee and Luma's relationship in the story. Apogee's people have a deep-seated prejudice towards dragons, since they were once at war with dragon invaders, and Luma has no fucking clue what his problem is, having only ever lived in Equestria her entire life. Shenanigans ensue.
Also if you haven't seen The Most Popular Girls In School you really should.
