[47][Speculation] Only one person wins immunity next episode / other changes to mergeatory.
There are two lanes, but it seems that Jeff is standing next to an individual immunity necklace, which he usually doesn't for the past earn the merge challenges.
Additionally, there's a bigger sit-out bench than usual in the back, so it's likely that it's a stage challenge where people get eliminated throughout. The press release also says that the advantage they're hunting for in the NTOS is for "a huge lead in the challenge," so it looks like they're doing something different for mergeatory?
