I wrote some things earlier about alpha and beta personalities. And what I am writing now will be very polarized.
Josy is a beta girl. She follows Maya, she follows MC. She is afraid of losing both of them. Already wanted to run away. The signs of this are many.
Maya is a hidden and suppressed alpha woman. (I can hear the groans of the community now) But given her past with a very dominant Alpha father, it is not surprising that Maya could not develop her Alpha skills. The characteristics of a positive alpha are present in Maya (self-confident, proactive, committed, independent and self-critical), but very underdeveloped. If she succeeds with the help of the MC to face the necessary confrontation with her father, the knot could burst with Maya.
Not sure I'd go for polarizing - I just don't see how you arrive at that conclusion?
Josy:
Was the one who initiated getting closer to MC suggesting the ride home and the date.
Invited MC for netflix and chill when her parents were out of town.
Was the 'leader' not the 'lead' in the camping flashback.
Up and ran from home with next to no money to attend B&R
Didn't back down to Quinn
and depending on your choices she's very much forward physically and will give Tommy a kicking if you wuss out.
The only time she's been 'submissive' and on the backfoot was during the M&J reveal and relationship up to the Library scene. I'd put that down to her one seeming weakness in that Josy doesn't thrive on being alone and left out.
As for Maya being an Alpha.............That'd be the same Maya who's been a plaything for Quinn, hostage to her dad, afraid to reveal her sexuality and on and on.
I'm not sure she even qualifies as Beta and is probably way back in Charlie.
EDIT: I'm not being a Maya hater but each girl fulfills a role in the game and where Jill is the refined young lady who you must despoil and turn into a woman, Maya is for the white knights who need to rescue a princess.
