That's the way I looked at it as well.My theory (Remember, I absolutely LOVE Quinn above everyone else in the game) is she asked the 8-ball if MC could love her if he found out about her past and her secret drug dealings.
I like Quinn. IMO she's capable of displaying the most character growth. She puts on a nice facade but her lack of courage in telling Tommy about the deal she made with the preps and the somber mood she falls into after being mugged is really all I needed to see.
Underneath that rough exterior she's soft as a feather. The MC is going to get past her defense mechanisms at some point.
