A Huge Strategic Threat

This is the 5th episode of Survivor: Bora Bora

Previously On Survivor...
After Porter was blindsided by Terrence's idol play, Angie needed to regroup. On Pahia, Vladimir's personality started to rub people the wrong way. On Noni, Bridgette was making allies. At the immunity challenge, Otemanu and Pahia won, sending Noni to tribal council where Al was the 4th person voted out.

16 are left; who will be voted out tonight?

Challenges
Immunity Challenge: Block It Out A pair of castaways from each tribe would swim out into the ocean to retrieve one of four crates with a different color on each face of a crate. Between the beach and crates would be a "battle zone" marked off by four flags. Within this zone, an opposing tribe member would try to prevent the two castaways from crossing the zone and reaching the crate. Once the two castaways crossed the zone, they would bring a crate back to the beach, and a second pair of castaways would go out to retrieve another crate. Once all four crates were retrieved, the crates would need to be stacked so that one color didn't show more than once on each column. The first tribe to complete the puzzle would win.

Day 12
The castaways walk into a suspected reward challenge.

Jeff Probst: Come on in guys!

The Otemanu and Pahia tribe walk into the challenge.

Jeff Probst: Otemanu and Pahia, getting your first look at the new Noni tribe, Al voted out at the last tribal council

Jeff Probst: OK, so we are actually not, competing in a challenge today.

The castaways looked surprised.

Jeff Probst: Drop your buffs, we are switching things up.

The castaways look surprised.

Tianna: Again?

Jeff Probst: But we are doing it a bit differently. The new twist is called Back in Time, where you will go back to the original tribe you were on.

The castaways cheer and grab new buffs.
