The promo literally shows us Natalie, Erik, and Amanda shooting, so I'm thinking it's going to be one of them. My guess at this point is that Erik is "on the chopping block" once James is out, and Amanda is formerly-powerful-now-desperate, so I think Natalie wins immunity. Which also would explain why go after injured Alexis out of their pair.

(Btw, Amanda has light blue around her middle, so yeah, it's nothing to do with teams.
