So I was messing around w/ Ep. 5 and a couple things popped out for me in the intro flashback (w/ Nick and Vinny joining the DiKs).
First, there's a throwaway line that seems to me to confirm the theory that Vinny is involved in the drug business. Rusty is talking about his dad's influence and how he's pretty sure he can use it to get them alcohol. Vinny then says: "Hey, if not, I know some guys, if you're looking to score." Not a smoking gun by any means, but I do think it's another bit of supporting evidence for the theory.
More puzzling, however, is something I never paid any mind to at the end of that same flashback. Rusty is showing Nick and Vinny the library, which Vinny claims for his own. The doorbell rings and Tommy calls out from off screen:
Tommy: "Rusty! I need some help over here."
Rusty: "Are you kidding me? Again?"
Tommy: "Yeah... Again."
Rusty then excuses himself and leaves Nick and Vinny alone to finish the scene. I have no idea what this little exchange is supposed to mean, or even if it means anything at all. It just stood out to me this time around, and since everyone here loves some good wild speculation, I thought I'd toss it out there and see what thoughts any of you might have about it, if any.
