As Taylor was attacking (yes, that's how I saw it ) Lisa, I noticed how uncomfortable the others were, especially Camille and Adrienne. They weren't backing Taylor up, and I found it interesting when Taylor said (to Paul?) "This wasn't how it was supposed to be" - or something like that...sounded like it it supposed to be a Lisa bash, but instead it turned back around to her (Taylor).
I agree with how you stated the second point and the Camille's implications of Taylor lying about abuse...my take on it was that Camille was frustrated and saying IF it were true, then do something about it (not her words, just how I took what she was implying). You stated it more clearly
