Maya is plagued by her supreme lack of confidence, something she seems to be finding more and more when the MC is around. She is smart, smarter than she appear at some points, and naive, you brought up good points about her upbringing, which ain't helping her at all. On the rare occasions she snapped, she was great, that slap on Quinn or that #FuckYouDawe moment on Rooster for example, but then her doubts comes back.
Hope DPC develops her more in the next episodes cause she really is lagging behind, that tuition thing has to resolve itself, one way or another.
