Josy doesn't need the money, but she sure could do it for Maya if she skips the free tuition.
Umm...there is no "free tuition". It's just a rumor that Quinn reinforces to lure more needy (let's be honest...) victims.
Quinn: "
Loose Hips, get Tips!"
"Free Tuition" is likely a scam perpetrated by Quinn to trick girls into agreeing to be prostitutes. The fact that it's a rumor is reinforced in the Quinn/Riona scene among a few other places. Someone "started" the rumor, and judging from the scene, it sounds like its probably Quinn (if not Mel and Sarah).
Apparently, the HOTS don't have enough money to pay their bills (let alone pay tuitions), thanks to Quinn blowing it on narcotics, loss of clients, and mismanagement (as revealed in Episode 5). But that's only temporary since they are only going to be able to hang on for a short time before falling behind again with the loss of revenue from losing the Alphas as clients, the possible ruining the deal with the Preps (possibly, considering the DIK interference at the party I doubt that the negotiations between Rich and Quinn become final, and I wouldn't be surprised if Tybalt doesn't end up paying the HOTs for the party after everyone evacuated) and now, thanks to screwing over Tommy (as he sees it), the loss of the DIKs for drug revenue. Quinn is screwed in Episode 6 and may need to do something desperate. Will she risk stepping up her prostitute game? I also think she's gradually losing Riona. Without her, I think Quinn is on even thinner ice.
