plain an simple at the end when she yells at hutch that is vivian accepting her situation but also mad at hutch for putting her in the situation that ultimately is destroying there marriage and well most likely going to end the marriage in some way shape or form at some point.
Once in a while Duke shows another face, it lasts for a while before it goes into a slut-fucking-ass phase
You see - you yourself are subject to some manipulation. A good puppeteer can set up the situation in such a way that his victims see no other way out, and it seems to them that they make their own decision. In fact, they are already set up like a deer on a dark night on the highway. He runs to where the lights are. Of course, the whole thing doesn't excuse Vi, because she made certain decisions fully consciously, becoming a classic slut (for me, such a final situation is the last evening). Of course, classically she can blame it on Hutch - because he, in a sense, allowed it, or rather, saw no other option.
