If it gets exposed. On the others route it's all but confirmed it's closed now.
Trust me, it will get exposed if independent accountants are going to look into Burke's books.
And apparently they are all (Quinn, Rio, Mel, Sarah, Cammy at least) able to finance their studys due to it somehow due to it at least
The restaurant can't be exposed (publicly at least, let one or two people like Sage find out, yes, but not a public scandal).
We're talking about a case where half the members of a sorority are prostitutes, if it becomes public all the members will be considered whores whether they were or not. So that would mean that the poor innocent girls would be condemned to flee to the other side of the country to hope to lead a life outside the scandal, and it involves 3 MGs, it's far too catastrophic for an ending, especially as it seems totally outside the MC's responsibility.
I'm sure there's no connection between Burke and the Restaurant. If we follow DPC's not-very-subtle-winking, I'm willing to believe we'll find that there's something fishy about Burke and the scholarships he can award at his whim, but it doesn't link him to the Restaurant; and if the winks are too obvious, I see it as more of a red herring.
I don't recall any reference to how Quinn, Rio, Mel, Sarah, and Camilla financed the college. I don't think their little prostitution business makes that much money. As for Burke paying for them (via scholarship), in that case why remove Maya's name from that scholarship because she tells him she's a HOT member ?
