But when one takes into account the other differences in how the cards talk about them, it could also take the meaning of them saying that May doesn’t belong with the HH/Mantle and is there due to some form of late teenage rebellion and should realise her place/happiness is in Atlas. While Fiona joining the HH and “becoming a criminal” is a shame but expected.

THERE SURE ARE SOME DIFFERENCES, HUH.

May is portrayed as “helping ‘maintain peace’ in Mantle” (which honestly, as a phrasing, frames her as some kind of cop; the kind of thing Atlesian sensibilities would see as valuable, since they’re more inclined to think of Mantle and the faunus as needing policing than protection) after leaving to prove that she was different from her family (and for no other reason), but not particularly enjoying her life.

Whereas Fiona’s cheerful nature is portrayed as just her default programming and used to infantilize her, by disregarding her passion and commitment to a cause and treating her as essentially a mascot (eugh) who’s Always Happy To Help! and would, clearly, be just as helpful and happy with a nice productive job serving Atlas by serving the Schnee Dust Company TM. Such a shame that such a sweet, friendly, innocent girl fell in with bad influences. But our view of her can’t possibly be racist, because we didn’t even mention her being a faunus!
