That wasn't for Jeff, that was for Natalie.
In the HOH Comp he put up Jeff and Russell. He's with Lydia and Lydia was balling her eyes out. I think the lines are drawn in the sand.
Chima told Kevin to put up Russell and Jeff, he just reacted. Chima knew what she was doing...but so did Jeff when he turned around and put up Chima and Nat.
Russell (if exposed for the Jessie vote) will just say that he was saving the men because the women are going to ban together. He said this to Jeff many times and Jeff may not like it, but he will understand why Russell voted to keep Jessie. They will remain together despite the Jessie vote.
Kevin was also just called Gucci by Jordan and Jeff, so Jeff is not against Kevin. It's a game and Jeff knows not to offend anyone. He's a very smart player. It's all numbers, not that he "trusts" them.
