I think
name88 made a pretty compelling case why Quinn and Tommy didn't have anything to do with these shenanigans. You don't make money by bringing your best customers into your pay roll, you don't make a hostile takeover if it means getting rid of your primary investor.
Not that Quinn doesn't have her schemes and Tommy might either have a part in it or his own if cares enough to drop his fix for 5min, but remember AL when all lights were pointed at
the rapist stepdad and his dirty cop partner and in the end it was
that crazy bitch? I think something similar, much more subtle, is going on.
