But there are fears about what could blow it all up.

One slip today and you’ll fall off track.
Tonight, another adventure ends.
This is the most important immunity challenge of this game so far, she explains.

Because there’s only four of us.
There are only four votes going out tonight, and they’re even.
But its not just the danger of a split vote that has Kamilla worried.
They’re all four people that we each want to work with, she continues.
None of us want to be at Tribal.
None of us want to send each other home.
This is by far the most important challenge in this game.
Sensing a merge right around the corner, Kamilla considers this last tribal immunity contest to be truly key.
We all like each other too much.
And that sudden connection has surprised even Kamilla.
You guys should have split the vote.
And I was like, Why is Joe taking it so personally?
And now, 48 hours later, I love them more than the Civa people.
It’s going to be rough.
