kiki, that's an amazing post.
I agree about Brenda's gameplay, entirely. Nice analysis of Parvati. It was always said that she was dangerous because she was so charming. We are not shown Brenda's charm. We've been shown that she tossed Chase aside in disdain. She seems to have forgotten about her numbers.

She and Sash were shown going from the head of a majority alliance of 5 or 6, to two swing votes. She was shown going from cultivating Jane to not hanging with her. In fact, no one was seen really hanging out with Brenda.

Na Onka was shown telling Chase not to irritate Brenda. For Na Onka to say something that socially aware, I think that Brenda must have major moodiness. It was interesting seeing Na Onka acting as glue between her allies.

Brenda was shown as not trying hard enough. She was not willing to pretend to be supportive of an ally.OTOH, we have seen Fabio and Ben shown as willing to play a role, whatever they need to do.

I love your idea of smart vs. dumb. Marty called Jane and Chase dumb and dumber. Marty was smart and is gone. Brenda was too happy and sure of herself when she won the IC. When Jeff asked her if she was sure she was right, she didn't hesitate. That is something other people see. She could have faked some doubt and tried to seem lucky that she remembered.

Before the swap, we saw Marty announcing that nothing could go wrong with his plans, then the rug was pulled out under him. Last episode, we saw Brenda saying she is in control. Following the pattern, she will have everything turn upside down the next day.

It is spoiled that Na Onka is going to tell Chase that Brenda is taking Nay and Purple to the F3, probably at the reward. Fabio will be there, and I hope we see him casting doubt and working Chase. Jane will surely turn on Brenda. People should start saying that Brenda is going to win if they don't take her out.

Sash was shown as a guy who takes care of himself only, so he won't fight it.
