In fact, Quinn was willing to vouch for Mona to Burke. I got the impression that Quinn wanted to give Mona another chance, but Burke is such a touchy bitch that he immediately сancel her grant. That's why I think Quinn sent the sex tape. That way she can control the unpredictable bastard Burke. And it doesn't look like Mona was kicked out. She left on her own, not wanting to do this anymore.
I don´t interprete it like that. I don´t know the scene in which Quinn is willing to vouch for Mona to Burke. This is the dialogue:
- Quinn: "Something to bear with you... Think of it as motivation. Do you think Professor Stephen Burke will allow a student to solicite sex on campus? Doing what you dis, put you on his radar. I know how to handle him, but I´m sure he wouldn´t like hearing that you´re out there blabbering about how he tried to buy sex from you. A man in his position, would probably reverse such a rumor and take action. Students have been expelled for far less and the whore label you´d get would be hard to shake. Don´t ruin your future, Mona."
That´s not "I will vouch for you to Burke". That´s is a thread to scare her to death.
Later, when Quinn and Riona talk, the dialogue is:
- Riona: "And what about Mona?
- Quinn: "I told you, I already handled her"
- Riona: "And that´s it!? Did you see her these last few days? She looks like she´s about to lose it"
- Quinn: "She won´t. She´s scared right now, but it will pass. I have it under control".
(...)
- Riona: "Given how it worked out with her (Mona), you should drop Maya before you even attempt something. I don´t have a good feeling about this. And lie it or not, I´m in this too. I you keep this up, I won´t be. (...) I don´t want to expand and take more risks."
(...)
- Quinn: "And to calm your nerves... I´ve decided that everything you said wasn´t stupid".
I think that what Quinn decided it wasn´t stupid is two things: that Mona is about to lose it and therefore, she is a serious threat to her business, and that Maya is another Mona, and it´s better not to try to get her into the "restaurant".
If Maya is not into the restauran, Quinn doesn´t need or want her into the HOTs, so she´s happy that she leaves. Problem solved, although Sage´s intervention opens the problem again for Quinn. But it´s not a big problem anyway. Maya actually knows shit about Quinn´s business. But being into the HOTs, she can listen an see things and connect the dots. We´ll see how the situation develops.
About Mona, potentially can ruin everything. Somebody as cautious as Quinn, and with her lack of scruples, don´t take risks. I think she just talked with Burke to get her expelled. Another problem solved.
What we now is Mona don´t left B&R by her own will, that´s for sure. Her best friend Camila says clearly she never though that she was on the verge of leaving. And she´s the one that better knows her. She was expelled by Burke.
