Rob and Russell were both cast on the same tribe on Heroes vs. Villains, but they were soon fighting for control of the Villains tribe. While they both started their own alliances, the Villains tribe won four of the five first challenges.
But when they finally went to tribal again, sparks flew. At a Double Tribal Council, Rob's alliance planned to split the vote between Russell and Parvati because they knew Russell had an idol. However, Rob's alliance member Tyson got spooked and voted for Parvati instead of Russell.
Russell played his idol on Parvati instead of himself, and Tyson ended up being voted out. The Villains then lost the next immunity challenge, and Rob was voted out.
