Now that's just overthinking the problem... Worst case scenario is her father getting the money she eventually needs to pay back for her education, she needs to pay that back eventually anyway so that doesn't change anything....
But the fact that remains is she will no longer be dependent on her father when she gets a scholarship so alot of her current problems get solved that way... The way to Josy is free and tuition is paid so she can continue her studies....
And aslong she is attending B&R she can prove she can't start paying back yet so if her father decides to say she doesn't study she can just prove her case and show proof of the scholarship or proof of attendance... Either the loan is for the full term and she can prove she does just that or the loan pays per semester and they will terminate further deposits but still refrain from demanding paybacks till her studies are completed, in that case the father will even receive less money and ultimately Maya will need to pay back less aswell!
but now you're making assumptions just like the ones we'd be wrong to make...
of course with a scholarship (which we still don't know if Burke will want or will be able to give her) Maya would be in the ideal situation she thought she could get with Quinn's free tuition (which was just to buy her time), but there is still the problem of the loan to pay back
the father could continue to play dirty, and could do so because it is a double signature loan (he could re-discuss it, ask for an integration etc.)
however as you see you can't simply say that Maya's father controls the membership money. you have to deal with what we have been told.
Many for example think that the solution will be to simply tell Maya that she has been cheated.
