Yes that if Josy wouldn't exist another girl would just magically appear, because that's how life works, is ridiculous indeed. That's the shoulda, coulda, woulda realm again. "doesn't stop her having a relationship with a girl that her father found out about" that's an instant classic. How did you call it ? Make shit up to fit ones own narrative ? Well that's a 10 out of 10.
And no it doesn't stop Maya from thinking she is a lesbian, but it also doesn't stop her from doing nothing to emancipate herself from her father.
Our discussion resolves around one major point if Maya wouldn't love Josy and be with her.
You believe that Maya would've tried to emancipate herself from her father no matter what.
I believe that Maya would tough it out through college and then live her life however she wants once she is done. Well that or discover that she is actually bi and likes boys too.
Sadly we will never get an answer, maybe we can ask Dalli to write a fanfic on how Maya and Josy dealt with their seperation.
