Russel & his pawns were supposed to vote for Courtney, not Coach this time. At 1st Russell wanted Coach out, but right before tribal council Danielle swayed him (after he told her he wouldn't change his mind). In the end it was Parvati that flipped & voted for Coach, not Courtney, which sent Coach home. Parv has her own agenda here, she's not stupid. Just like Jeff said in his blog - when Ruseell had one iota of doubt about Parv he should have run with that gut instinct - instead his ego got in the way & it never crossed his mind that Parv would go against him. I think she has a Plan B & going against Russell in this week's vote was the start. I bet that was in interesting walk back to camp once Russell realized his precious Parv went against his demands & didn't vote for Courtney. I wouldn't doubt if Parv IS behind an all-girl alliance from this point on.
Although with editing who knows what really happened...Russell didn't seem shocked that Coach went, even though he told his co-horts to vote for Courtney, so maybe something went on behind the scenes that they didn't show.
