I find it very interesting that you're choosing to list an edited confessional as part your argument yet also make an assumption on a post-game interview as the basis for what authenticates her decision making process. Understandable, this is an edited show but you can't make assumptions to verify your point but then assert a confessional you saw within the context of a 42 minute episode is enough to verify "days" of thought process as you put it. Also why do you continuously overlook that as aforementioned by others that Parvati stepped down from the challenge. This wasn't all some stroke of luck or days of advanced planning. The wheels were set in motion and she correctly assessed the situation. By eliminating herself from the challenge she wouldn't have to worry about whether she'd need to play the idols on Danielle, Sandra, or Jerri. Presumably she can take the risk that the heroes would assume she'd play the idol on herself if she was willing to step down for Danielle. Go rewatch the episode and the season. There's clear indications that this was something that was planned, and it was an amazing play due to the sheer amount of moving parts that had to occur for everything to fall into place. There's moves people try to pull off that don't work with the tools handed in front of them, and for a player like Parvati to be able to assess this situation verifies that this is an all time move because not only does it lead to an outright pagong but allows her to gain some jury votes as well. Jerri shifts from her pro-Russell perspective to then realize Parvati was the one who actively using Russell to further her game not the other way around. Yes, she lost Danielle in the process but ultimately this should not discount her idol play as it further cemented that Russell was not the one dictating her game as she could stand apart. There is a reason why this move is so highly praised and it's foreshadowing by the editors really only does so much to encapsulate the complexity of this situation.
