True, true. I think some consideration should be given though since its paired with MC calling Quinn evil. I think it goes something like "Quinn's evil, you don't know what she does with her girls, she uses them to make money". Something to that effect, iirc.
But yeah, since MC clams up, you can't really blame Maya for not getting the message. That said, I feel like after the pool party in ep3 with Quinn offering the tuition paired with her "wide hips get tips" line, only a moron wouldn't understand whats going on.
