Josh is the target, but they want it to be a complete surprise. The boys and Natalie are acting like they are on Josh's side.
I have to say that they are convincing. Every other moment, I think someone has switched their vote. But every time the group as a whole (no Josh/James), they talk about how well their plan is working.
Plan: Josh feels safe, James bonds with Josh again, slam Josh out 4-1, fluster James right before the HOH competition.
