I think that is my biggest issue with Candice. I don't really get what's going on with the heroes, but the villians obviously have a plan, so even if you believe everything Russell tells you (and let's face it, he's been completely honest so far

), you are on the outs to begin with. He basically told her, "we have a stronger, larger alliance than the heroes and if you join us, I think you'll make top 3". Really? More numbers is going to get you further?
The stupid thing is that she had the numbers and better. Sandra is easy pickings no matter what tribe you are on and as mentioned, Colby doesn't seem to have any motivation anymore. Amanda wants to win it and would be an eventual threat, but she's no tougher than any one of the other remaining villians. So how dumb is she or what didn't we see that made her think that she has a better chance by switching? That just doesn't make any sense to me at all.
Even if you think Sandra is disengenuous, then come up with a plan that benefits you either way like they tried last week (and would have succeeded had P not had 2 idols).
The best part of all of this is that had they wanted to, they could have eliminated Pavarti two weeks in a row now had they just tried.
BTW - our discussion last week about Rupert not being able to convince people and someone commented that you thought he did convince them, which is why they voted for Jerri. Had they really been convinced, they could have voted off Russell himself last week and it would have worked.
