Jeff and Russell are working together after last week, and Russell will go home if Jeff doesn't take him off. If I were him, I'd nominate Jessie and Natalie to guarantee one of them goes home. That takes that alliance down to 2 - Chima plus whoever's left (prob. Natalie since Jessie's the bigger threat). Then those are the only two people to worry about come HOH time, and Chima wouldn't even be eligible to compete this next week and Natalie hasn't done well in any comps. Someone's gonna come after Jeff and Jordan's alliance pretty soon, so he might as well give this a try to save one of his friends in the house.
