You might consider that Renee is pretty much Faye before she hit bottom and bounced....
Disagree. Faye was abrasive and mean at time, but it was petty and had no spite or fear behind it. At worst, Faye was alcoholic and ultra-defensive about it, but never mean-spirited. Faye was, even when being mean, doing it out of a twisted sense of humor.
Renee appears to be just as mean deep down as she is on the surface. She appears to really hate and distrust men, to the point where even a man she's never seen, who has been mentioned secondhand as a helpful guy, is presumed evil. And not just for laughs. Renee hasn't said anything funny that I can recall. She's just a misanthrope, possibly with previous trauma that she's obviously not going to try to work through. A seething victim. Not my favorite sort of person.
