Joshy, just don't be mad, but what if... What if Maya beat up Quinn and stole her drugs? At first I thought it's a bullshit, but think about it: Maya hates Quinn, and Maya has money problems. She already tried to beat her and even slapped her! She was desperate for money, she was ready to sell her ass to do whatever it took to earn it. Put two and two together. Connect two dots. Stick your dick in crazy... No, don't mind the last one, it's irrelevant.
So now she has Quinn's stuff, but she'll have to sell it. Where do you think she'll do it? So, the chances of her running into both Vinny and Quinn are pretty high, and you really should be prepared!
