"Chris, I, Scout, we have the power now"
Leann Slaby (Vanuatu)
I could watch this blindside and the subsequent reactions to it over and over again. Most Survivor fans will agree that this is without question the definiton of a "power shift" -- Not the majority deciding to turn on a threat and eat one of their own for one round, but an honest-to-God switcheroo.
After the merge, the 6 remaining women in the game banded together to vote out Rory, Sarge, and Chad in quick succession. Though cracks were beginning to form, their majority remained intact and Chris was soon the only male left standing.
Here, the dominant threesome of Leann/Ami/Julie made a crucial mistake. They decided they wanted to switch the vote from Chris to Eliza for no real reason at all, and Scout and Twila saw this as their chance to change the game. Chris eagerly hopped on board and let Eliza know that she would be going home unless she voted with him. Thus at Tribal Council Leann was blindsided 4-3, and Chris and Eliza flashed shit-eating grins at the camera.
The reactions to the blindside were also priceless, from Ami trying to guilt trip Eliza for *not getting voted out* to Twila basically saying "lol u mad?" over and over and over. Twila/Scout/Chris/Eliza is one of my all time favorite reality TV alliances, and though they only lasted for like 2 episodes and ended in Eliza going off on Twila for the 18th time, I love them all to pieces.
Either Erik or James...
Erik giving away his necklace only to get turned on (losing him the game that he had a good chance of winning)
James getting blindsided at the final 7 with two idols in his pocket...
