Rupert and Colby were two of my favs in their seasons...but they suck this season! It's like James said, "My Superman sucks!"
Remember not even Russell knows Parvati has the idol. All they need to do is tell the heroes that Parvati had saved him so he couldn't take her out. Like it was already mentioned, the heroes wouldn't know the real story anyway. Russell needs to claim he is aligned with the heroes (which is looks like in the previews that's what he's doing) and then let one of the girls play the idol that JT gave Russell.
In the heroes minds, this is the hidden idol from the villains camp since Russell needs to claim he already played it to save his butt. And Parvati...well, as much as I dislike her, gets to do what she wants with her idol....hopefully shares it with Russell.
As far as Sandra, YES, they should've gotten rid of her! How stupid. But, then again, it's her word against everyone else's....they could try to convince the heroes that she is just trying to stir things up. If they believe Russell is the odd man out and the vottes have "appeared" to go against the guys, I don't think they'll believe her much. It'll make them think, yes, but Russell is smarter than her
It'll be interesting regardless of what happens
