Not sure what you mean; i'm basically responding to a claim that "Quinn never promised Maya free tuition, no one did, that was a rumor she heard and decided to treat it as a fact." (which, as we can see, is bullshit)
That's a pretty bold statement.
Except it's not actually factual, just your interpretation.
In the first episode (after MC get his clothes, phone and guitar back) Quinn said this:
Q: I'm not going to say I'm sorry, because I'm not. What you did was a fucking scumbag thing to do.
MC: But I-
Q: Shh!
Q: I like to fuck with people. Some like that, some don't.
Q: So, no harsh feelings?
And now with that in mind, let's go back to that scene at the beginning of episode 3 that you mentioned.
Quinn: And while we wait, as a vice president, I wanted to take the time to shine the spotlight on Camila for her excellent performance during the DIKs' CUM-petition.
...
...
...
Quinn: Camila?
Camila: Yes?
Quinn: You've had the luxury to get closer to the HOTs than Maya and...
Mona: Mona.
Quinn: Really? Maya and Mona, hah.
Quinn: Do you like the opportunity you've been given?
Camila: Yes, Quinn. I... love it.
Quinn: Good answer.
Quinn: You see, I'm beginning to think that Maya and Mona, here, might be suitable as well.
Quinn: Would you agree?
Camila: I quess. Sure.
Maya: What's the offer?
Quinn: Oh, you will like this.
Quinn: I'm aware that you ladies have heard some rumors about the HOTs, right?
Maya: I've heard something about... free... tuition.
Quinn: Did you hear about that, as well, Mona?
Mona: It's been mentioned in whispers.
Quinn: Ah! The grapevine...
Quinn: Seems like there's a HOT among us who can't keep her trap shut.
Quinn: You know how the saying goes...
Quinn: Loose lips, sink ships.
Quinn: But loose hips, get tips.
Quinn: So, girls...are you interested?
Mona: Free tuition? Sign me up.
Mona: I'm not passing on that offer.
Quinn: And you, buttercup?
Quinn: Are you in?
Maya: What do we have to do, exactly?
*Sage appears*
At what point does Quinn promise anything to Maya?
She
didn't.
Or do you assume the question of whether you're interested in something = a promise?
And even if Quinn supposedly promised, unlike Mona, Maya didn't even agreed
Furthermore,
Quinn has nowhere directly confirmed that it's not a rumor.
She may have just been playing with Maya and Mona, teasing them for their naivety.
